Top Tips: Enjoying Christmas Without The All-or-Nothing Vibes
At this time of year the messages around food and drink tend to fall into two camps. Either it is Christmas so anything goes until January, or it is all about "damage limitation", saving calories for the party and "burning off" the mince pies. Neither tends to leave people feeling particularly festive…
I would love you to try a different approach this year. Instead of strict rules, keep a few simple anchors in place so that you can enjoy the food, the drinks and the company - and still feel like yourself. Here are my top tips, based on the evidence and on what I see work for clients year after year.
1. Keep Your Everyday Anchors
The most helpful thing you can do over the festive season is keep some of your normal routine going. Regular meals, a breakfast that includes protein, and plenty of vegetables on most days give your body a sense of rhythm when everything else is busier than usual.
This is not about being "good". It is simply that steady, balanced meals help to keep energy and appetite more even, which makes it easier to enjoy the treats without feeling out of control. If you would like a reminder of how to build a balanced plate, take a look at Balance Your Plate Balance Your Energy.
2. Don't Arrive at the Party Hungry
Skipping meals to "save up" for an evening out often backfires. Research shows that alcohol tends to increase how much we eat rather than replacing food and arriving ravenous makes that effect more noticeable.
A proper meal or a satisfying snack before you go, ideally with some protein, fibre and healthy fat, can help. Think a bowl of soup with beans, eggs on wholegrain toast, or Greek yoghurt with nuts and berries. Having food in your stomach also slows down how quickly alcohol is absorbed, which the NHS recommends if you are drinking.
3. Know Your Pour
It is very easy to underestimate how much you are drinking at Christmas. Glasses are often large and get topped up before they are empty.
According to the NHS, a standard 175ml glass of 12% wine is 2.1 units, while a large 250ml glass is 3 units. A 125ml glass of 12% prosecco is around 1.5 units, and a pint of 5.2% lager is 3 units. Many red wines are 13.5% or more, so the numbers can be higher still. Asking for a small glass and letting it empty before it is refilled are simple ways to keep track without needing to count every sip.
4. Alternate and Explore Alcohol-Free Options
Alternating each alcoholic drink with water or a soft drink is one of the easiest habits to adopt, and it helps with thirst and pacing. The range of alcohol-free and low-alcohol drinks has also improved enormously, from alcohol-free wines and beers to botanical spirits and kombucha.
At home, sparkling water with fresh orange slices, a cinnamon stick and a few cranberries feels just as festive in a nice glass. Having something you genuinely enjoy in your hand makes it much easier to skip a drink you did not really want.
5. Keep Some Drink-Free Days
The UK Chief Medical Officers advise not regularly drinking more than 14 units a week, spread over three or more days, with several drink-free days each week. Over Christmas, it can help to look at your diary and decide in advance which evenings will be drink-free.
It is also worth knowing that "saving up" units for one big night is not the answer. The guidance specifically advises against heavy drinking in a single session, because the short-term risks rise quickly. And as I explained in my blog on alcohol and sleep, drink-free nights are often the ones when you sleep best.
6. Add Before You Subtract
Rather than focusing on what to cut out, think about what you can add. Christmas is a wonderful time for seasonal vegetables: Brussels sprouts, red cabbage, parsnips, carrots, kale and chestnuts, not to mention clementines and pomegranates.
Filling half your plate with vegetables at the big meals adds fibre, colour and plant compounds, and naturally leaves a little less room for the heavier foods without any sense of restriction. Most of us fall short of the NHS recommendation of 30g of fibre a day, so this is a gift to your gut too. If festive bloating is an issue for you, my blog How to beat the festive bloat has some practical ideas.
7. Move for Enjoyment, Not to "Burn It Off"
I would love us to retire the idea of exercising to cancel out food. Movement has so many benefits for mood, sleep, blood sugar and heart health that it deserves better than being used as a punishment.
A walk after Christmas lunch is a lovely tradition, and research suggests that even short bouts of walking after a meal can help to moderate the rise in blood sugar that follows it. A family walk, a dance in the kitchen or a game in the garden all count.
8. Enjoy It, Then Move On
Choose the festive foods you really love and savour them properly, sitting down and without distraction. If there is something you only eat because it is there, it is fine to leave it. I couldn’t go through Christmas without having a proper mince pie!
Then, if you have a bigger meal or a later night than planned, simply return to your usual way of eating at the next meal. There is no need to skip breakfast, start a detox or "be good" until January. As I explained in Why Detox Diets Don't Work and What to Do Instead, your liver and kidneys do that job very well on their own.
Start With One Thing
You do not need to do all of these. Pick the one or two that feel most realistic for you this December and let the rest go. Small anchors, kept consistently, are far more powerful than a perfect plan you abandon by the 20th.

Alcohol, Sleep and Appetite: Why a Few Drinks Leave You Tired, Hungry and Bloated
December is the month when many of us drink perhaps a little more than we might do usually... There’s the work Christmas party, drinks with your mates, a glass of something while wrapping presents, and the long, sociable meals over Christmas and Boxing Day. None of that is a problem in itself, and I promise you this isn’t a blog about giving everything up!
But what I do hear in clinic at this time of year, though, is a very similar set of complaints.
If any of that sounds familiar, it might help to understand what alcohol is actually doing in your body. Knowing the why makes it much easier to decide what you want to do about it.
What Happens to Your Sleep?
Alcohol is a sedative, which is why a drink or two can make you feel drowsy and why so many people use a nightcap to help them drop off. The trouble is that falling asleep and sleeping well are not the same thing.
A 2025 systematic review and meta-analysis in Sleep Medicine Reviews pooled 27 studies looking at how alcohol affects the sleep that follows it in healthy adults. The researchers found that alcohol delayed the onset of REM sleep and reduced the total amount of it, and that this happened even at the lower doses studied, getting worse as the dose went up. Interestingly, the faster drop-off that people notice was only clearly seen at the higher doses, around five drinks or more.
REM sleep matters. It is the stage most closely linked with emotional processing, memory and that feeling of having had a genuinely restorative night. Losing some of it is one reason you can sleep for seven or eight hours after a night out and still wake up feeling as though you have barely slept.
There is also a timing effect. Your liver works through alcohol over the course of the night, and as levels fall, sleep in the second half of the night tends to become lighter and more broken. This is the classic pattern of sleeping heavily for a few hours and then waking in the early hours, often feeling hot, restless or wired.
A few other factors add to this as well. Alcohol suppresses vasopressin, the hormone that helps your kidneys hold on to water, so you are more likely to wake up needing the loo. It relaxes the muscles of the upper airway, which can make snoring worse, and has been linked with a higher risk of obstructive sleep apnoea. And for women in perimenopause or menopause, alcohol is a commonly reported trigger for hot flushes and night sweats.
Why Am I So Hungry After Drinking?
If you have ever found yourself at the kitchen counter at midnight eating cold roast potatoes, you are not lacking willpower! There is good evidence that alcohol changes how we respond to food.
A 2019 systematic review and meta-analysis in the British Journal of Nutrition looked at studies where people were given alcohol before or with a meal. On average, they went on to eat more food, around 340kJ (about 80kcal) more than when they had a non-alcoholic drink, and their bodies did not compensate for the energy in the alcohol itself. Total intake rose by around 1,070kJ (about 250kcal) per occasion.
Why might this happen? One interesting study published in the journal Obesity in 2015 gave 35 women either alcohol or a saline placebo through a drip, so the alcohol bypassed the gut entirely. After alcohol, a part of the brain called the hypothalamus, which helps regulate appetite, responded more strongly to the smell of food, and on average the women ate more at lunch. Researchers sometimes call this the "apéritif effect". Alcohol also lowers inhibition, so the plan to have a light supper can quietly become something else entirely.
The effect often carries into the next day. Poor sleep is strongly linked with increased hunger and a pull towards quick, sugary and salty foods, which is why the morning after can feel like one long craving.
Why Do I Feel So Tired and Bloated the Next Day?
Most people put next-day fatigue down to dehydration. Alcohol does make you pass more urine, and staying hydrated is sensible, but research into hangovers suggests dehydration is only part of the picture. Studies have not found a strong link between markers of dehydration and how bad a hangover feels. Broken sleep, the build-up of acetaldehyde (a toxic by-product as your liver breaks alcohol down) and an inflammatory response all seem to play a bigger role. In other words, a pint of water before bed is a good idea, but it will not fully undo a short night of fragmented sleep.
Bloating is a very common complaint too, and there are several reasons for it. Alcohol can irritate the lining of the stomach and relax the valve at the top of it, which is why the NHS lists it as a trigger for indigestion and heartburn. Fizzy drinks such as beer, prosecco and mixers add gas. Drinks are often paired with rich, salty or large meals, and a disrupted night can leave your digestion feeling sluggish. Over time, regular heavier drinking can also affect the gut lining and the balance of the gut microbiome, which is something I look at closely with clients who have ongoing digestive symptoms. If bloating is a regular issue for you, you might find The Fibre Mistake That's Making Your Bloating Worse helpful too.
How Much Is Too Much?
The UK Chief Medical Officers' guidelines, which the NHS follows, advise that men and women do not regularly drink more than 14 units a week. If you do drink as much as 14 units, it is best spread over three or more days, with several drink-free days each week.
It is worth knowing what that looks like in a glass. According to the NHS, a standard 175ml glass of 12% wine is 2.1 units, and a large 250ml glass is 3 units. A bottle of 13.5% wine is 10 units. Many Christmas wines are stronger than 12%, and glasses at parties are often generously filled, so units can add up more quickly than you think.
It is also important to be clear that "low risk" does not mean "risk free". The 14-unit guideline is a level at which the risk of harm is kept low, not a target or a level at which alcohol becomes good for you. I looked at what alcohol does to the liver in Sugar, Alcohol and your Liver, and I will explore the "healthy drinking" idea in more detail in my next blog on red wine.
So, What Can You Do?
None of this means you cannot enjoy a drink this Christmas! It simply means you can make choices with your eyes open.
Having your last drink earlier in the evening gives your body more time to process it before sleep. Eating a proper meal with protein and fibre before or while you drink can help with the late-night hunger that follows. Alternating alcoholic drinks with water or a good alcohol-free option, and keeping a few drink-free evenings in your week, can make a real difference to how you sleep and feel. I will share more practical ideas in my Top Tips blog later this month [LINK TO TOP TIPS BLOG ONCE LIVE].

Top Tips for Supporting Your Brain Health
If you are noticing more brain fog, forgetting names, struggling to concentrate or simply thinking more about how to protect your brain as you get older, it can be difficult to know where to start.
There is certainly no shortage of advice. Take this supplement. Avoid that food. Do a daily crossword. Eat more blueberries. Buy a continuous glucose monitor.
But the best research tells a much less complicated story.
Brain health appears to benefit most when we look after several different areas at the same time: cardiovascular and metabolic health, nutrition, movement, sleep, hearing and vision, mental stimulation and social connection.
The 2024 Lancet Commission estimated that around 45% of dementia cases worldwide could potentially be delayed or prevented by addressing 14 modifiable risk factors throughout life.
That does not mean dementia is always preventable. Genetics, ageing and many factors outside our control remain important. But it does mean there are plenty of things we can do to create a healthier environment for our brains to age in.
Here are some good places to start:
1. Eat for Your Brain and Your Heart
One of the most consistent findings in brain-health research is that dietary patterns matter more than individual “superfoods”.
Mediterranean, DASH and MIND-style diets differ slightly, but they have far more similarities than differences. They tend to contain plenty of vegetables, fruit, beans and lentils, nuts, seeds, wholegrains, olive oil and fish, with fewer ultra-processed foods.
The evidence is not strong enough to say that any one of these diets prevents dementia. Instead, look at what these eating patterns have in common.
Try this: Aim to include vegetables or fruit at every meal, use extra virgin olive oil regularly, eat beans or lentils several times a week, include nuts and seeds, and choose minimally processed foods most of the time.
2. Look After Your Blood Sugar
The brain is highly energy dependent, but that does not mean it benefits from constantly high blood glucose.
Insulin resistance and type 2 diabetes are associated with an increased risk of cognitive decline and dementia. Diabetes is one of the 14 modifiable risk factors highlighted by the Lancet Commission, and the new WHO dementia risk-reduction guidance specifically recommends managing diabetes alongside other cardiovascular risk factors.
For day-to-day concentration, meals dominated by rapidly digested carbohydrates can also leave some people feeling hungry, tired or mentally flat a few hours later.
Try this: Build your meals around a good source of protein, plenty of vegetables and a sensible portion of fibre-rich carbohydrate.
For example, rather than toast and jam on its own, try eggs with wholegrain toast and vegetables, or Greek yoghurt with berries, seeds and oats.
You can read more about this in my article What is Causing my Brain Fog?
3. Don’t Forget Protein
We tend to associate protein with muscles rather than the brain, but maintaining muscle mass is an important part of healthy ageing.
Muscle is a major site of glucose disposal, so preserving muscle mass can support insulin sensitivity. Protein also provides amino acids required throughout the body for enzymes, hormones and neurotransmitter production.
This becomes particularly important from midlife onwards, when maintaining muscle can become more difficult.
Try this: Include a meaningful source of protein at each meal rather than leaving most of your protein until dinner.
Think eggs, Greek yoghurt, fish, chicken, tofu, tempeh, beans, lentils, cottage cheese or lean meat.
4. Eat Your Omega-3s Before Reaching for Supplements
DHA is an important component of brain-cell membranes, and oily fish is a regular feature of Mediterranean and MIND-style dietary patterns.
But supplements are not automatically better. The updated WHO guidance does not recommend omega-3 supplements specifically to reduce the risk of cognitive decline or dementia in people without a diagnosed deficiency.
That is an important distinction between supporting good nutrition and trying to treat or prevent disease with supplements.
Try this: Aim to eat oily fish regularly. Good options include salmon, sardines, mackerel, trout and herring.
If you do not eat fish, discuss suitable alternatives with a qualified practitioner rather than assuming you need a very high-dose supplement.
5. Eat More Colour
Blueberries often receive the “brain food” headlines, but they are not magical.
What is interesting is that berries, colourful vegetables, herbs, spices, tea, coffee, cocoa and extra virgin olive oil contain plant compounds called polyphenols.
Polyphenols interact with inflammatory signalling, vascular function, antioxidant defence and the gut microbiome. This is one reason researchers increasingly focus on dietary diversity rather than individual nutrients.
Try this: Instead of counting blueberries, count colours.
Across the week, include greens, reds, purples, oranges and yellows. Think broccoli, spinach, tomatoes, peppers, berries, beetroot, red cabbage, herbs and spices.
The more varied the plant intake, the broader the range of nutrients and plant compounds you are likely to consume.
6. Move Your Body and Pick Up Some Weights
If I had to choose between an expensive “brain supplement” and regular physical activity, the evidence would strongly favour movement.
Exercise research increasingly shows benefits for cognitive function, with aerobic, resistance and combined exercise all showing positive effects in older adults. Recent meta-analyses suggest resistance exercise may be particularly useful for several aspects of cognition.
Then there is the bigger multidomain evidence.
The Finnish FINGER trial combined nutrition, exercise, cognitive training and cardiovascular monitoring. More recently, the 2025 U.S. POINTER trial studied 2,111 older adults at increased risk of cognitive decline. Both lifestyle groups improved cognition, with greater benefit in the more structured intervention.
Try this: Combine everyday movement with both aerobic and resistance exercise.
Walk briskly, cycle, swim or dance, but also challenge your muscles two or more times each week if appropriate for you.
Your muscles are not separate from your metabolic or brain health.
7. Know Your Blood Pressure and Cholesterol
This is not as glamorous as buying nootropics, but it may be considerably more important.
High blood pressure and high LDL cholesterol are both recognised modifiable dementia risk factors. The 2024 Lancet Commission specifically added high LDL cholesterol in midlife to its list of factors associated with dementia risk.
What protects the blood vessels supplying your heart also helps protect the blood vessels supplying your brain.
Try this: Know your blood pressure, cholesterol and HbA1c, particularly from midlife onwards.
If they are raised, speak to your GP. Nutrition and lifestyle can support cardiovascular health, but they should complement appropriate medical management rather than replace it.
8. Take Sleep Seriously
We all know how poorly the brain works after a bad night's sleep. Attention, memory, decision-making and reaction times can all suffer.
The longer-term relationship between sleep and dementia is more complicated. Observational research links abnormal sleep duration and some sleep problems with increased dementia risk but cause and effect can be difficult to untangle because early brain changes may themselves disturb sleep.
One issue that should not be ignored is sleep apnoea.
Try this: Prioritise a regular sleep routine and speak to your GP if you snore heavily, stop breathing during sleep, wake repeatedly gasping or feel unusually sleepy during the day.
Better sleep is worthwhile for your brain now, even before we consider long-term risk.
9. Look After Your Hearing and Eyes
This is probably one of the more surprising brain-health recommendations.
Hearing impairment and untreated vision loss are included among the Lancet Commission's modifiable dementia risk factors. The new WHO guidance also recommends considering hearing aids as part of dementia risk-reduction strategies where appropriate.
Top Tips: Eating for Healthy Skin We often think of skincare as something that happens in the bathroom. We cleanse, moisturise, exfoliate and apply sunscreen, yet the skin is also maintained from within throughout the day. Skin cells need energy and nutrients. Collagen formation requires amino acids and vitamin C. The skin barrier contains fats that help limit water loss, while antioxidant defence systems rely on nutrients obtained through the diet. This does not mean that one food will clear acne, cure eczema or remove wrinkles. Skin health is influenced by hormones, genetics, immune function, medication, sun exposure, stress and skincare, as well as nutrition. However, food provides many of the raw materials needed for normal skin structure and maintenance. A varied diet containing adequate protein, healthy fats and plenty of colourful plants is likely to offer more meaningful support than chasing the latest so-called superfood. Here are my top tips for eating for healthy skin. 1. Eat the Rainbow, but Understand Why “Eat the rainbow” can sound like vague nutrition advice, but the colours in plant foods often represent different families of naturally occurring compounds. Tomatoes and watermelon contain lycopene. Carrots, squash and sweet potatoes provide beta-carotene. Dark leafy vegetables contain lutein and beta-carotene, while berries, red cabbage and blackcurrants contain anthocyanins. Many of these compounds interact with the body’s antioxidant defence systems. Your body naturally produces reactive molecules during metabolism, energy production and immune defence. Oxidative stress occurs when the production of these molecules exceeds the body’s capacity to manage them. Within the skin, ultraviolet radiation, pollution and cigarette smoke can add to this burden. Excessive oxidative stress may damage cell membranes, proteins and DNA. It can also activate inflammatory pathways and enzymes involved in breaking down collagen and other components of the skin’s supporting structure. The aim is not to eliminate oxidation. Reactive molecules also perform useful biological roles. Instead, the goal is to provide the nutrients the body uses within its own defence and repair systems. Regularly include a mixture of berries, cherries, plums, blackcurrants, tomatoes, peppers, watermelon, carrots, pumpkin, sweet potato, broccoli, watercress, leafy greens, red cabbage, beetroot and aubergine. Herbs, spices, tea, coffee and cocoa also contribute useful plant compounds. You do not need every colour at every meal. Aim to eat several colours across the day and vary them throughout the week. 2. Include Vitamin C-Rich Foods Every Day Vitamin C is one of the nutrients most directly involved in normal skin structure. It contributes to normal collagen formation for the normal function of skin and also contributes to the protection of cells from oxidative stress. Collagen begins as chains of amino acids. Before these chains can become strong, stable collagen fibres, they must undergo several chemical modifications. Vitamin C acts as a cofactor for enzymes involved in this process. In simpler terms, protein provides the building materials, while vitamin C helps the body assemble them into normal collagen. Useful sources include red and yellow peppers, blackcurrants, strawberries, kiwi fruit, citrus fruit, broccoli, Brussels sprouts, watercress, leafy greens, tomatoes and new potatoes. Vitamin C is water-soluble and can be reduced by prolonged cooking, so include a mixture of raw and lightly cooked produce where possible. 3. Do Not Forget Protein Collagen is a protein, and normal tissue maintenance depends on an adequate supply of amino acids. This does not mean that eating collagen sends it directly to the face. Dietary proteins are broken down into amino acids and small peptides, which the body then uses for muscles, enzymes, immune proteins, connective tissue and skin. Protein intake is often uneven. Breakfast may consist mainly of toast or cereal, lunch can be light, and most of the day’s protein is left until dinner. Including a meaningful protein source at each meal makes it easier to meet overall requirements. Good options include eggs, fish and seafood, poultry, lean meat, Greek yoghurt, cottage cheese, kefir, tofu, tempeh, edamame, beans, lentils and chickpeas. Plant-based diets can provide the amino acids required for the body’s own collagen production. Plants do not contain collagen, but this does not mean animal collagen must be eaten. The important factors are sufficient total protein, enough energy, dietary variety and an adequate intake of vitamin C. 4. Make Polyphenols Part of Ordinary Meals Polyphenols are a large family of plant compounds found in vegetables, fruit, tea, coffee, cocoa, herbs, spices, nuts, seeds and extra virgin olive oil. Laboratory studies suggest that some polyphenols interact with antioxidant defence, inflammatory signalling and enzymes involved in collagen breakdown. Human evidence is more variable because polyphenols are extensively digested and metabolised. Their effects also depend on the food, the amount consumed, the gut microbiome and the wider dietary pattern. This means it is more sensible to eat a wide range of polyphenol-rich foods than to expect one ingredient to transform the skin. Easy ways to increase them include adding berries, cherries or chopped apple to breakfast, using extra virgin olive oil on salads and vegetables, adding herbs and spices generously to meals, drinking green or black tea, choosing red onion, red cabbage and aubergine, and adding natural cocoa to yoghurt or porridge. Cocoa is an interesting example. Some small controlled studies using specially standardised high-flavanol cocoa products have reported changes in skin blood flow, elasticity or responses to UV exposure. These products are not the same as an ordinary chocolate bar, so the research does not mean unlimited chocolate becomes a skincare strategy, unfortunately. A couple of squares of dark chocolate can, however, be enjoyed as part of a balanced diet. 5. Include Omega-3 Fats Regularly Fats are sometimes overlooked in conversations about skin, yet the skin barrier contains a complex mixture of lipids that helps restrict excessive water loss and protect against the external environment. Omega-3 fatty acids are also used to produce signalling molecules involved in regulating inflammatory responses. The most biologically active omega-3 fats are EPA and DHA, found mainly in oily fish such as salmon, sardines, mackerel, trout, herring and anchovies. UK guidance recommends eating at least two portions of fish each week, including one portion of oily fish, although maximum recommended intakes differ for certain groups. Walnuts, chia seeds, hemp seeds and ground flaxseed provide the plant omega-3 fat alpha-linolenic acid, or ALA. The body can convert some ALA into EPA and DHA, but the conversion is limited. These foods remain valuable sources of fibre, minerals and unsaturated fats, although they are not nutritionally identical to oily fish. People who do not eat fish may wish to use omega-3-fortified foods or discuss an algae-derived EPA and DHA supplement with a suitably qualified professional. Research into omega-3 fats and individual skin conditions remains mixed, so oily fish should not be presented as a treatment for acne, eczema or rosacea. It can, however, form part of a balanced dietary pattern that provides fats needed for cell membranes and normal inflammatory regulation. 6. Use Extra Virgin Olive Oil as a Daily Staple Extra virgin olive oil is more than simply a source of monounsaturated fat. It also provides phenolic compounds that distinguish it from more heavily refined oils. It is a central part of the traditional Mediterranean diet, alongside vegetables, fruit, beans, lentils, wholegrains, nuts, seeds, herbs and fish. Research has associated Mediterranean-style dietary patterns with better cardiometabolic health and more favourable markers of inflammation and oxidative stress. Direct evidence relating specifically to skin appearance is less extensive, so it should not be promoted as a wrinkle-reducing diet. Its value is that it brings together many nutrients involved in normal skin maintenance, including vitamin C, carotenoids, polyphenols, omega-3 fats, protein, vitamin E, zinc and selenium. Use extra virgin olive oil as a salad dressing, drizzle it over cooked vegetables or add it to beans, soups and wholegrains. It can also be used for normal home cooking. There is no need to save it exclusively for cold dishes, although repeatedly overheating any oil should be avoided. Food cannot promise flawless or ageless skin. What it can do is provide nutrients involved in normal collagen formation, antioxidant protection, tissue maintenance and the function of the skin barrier.

Persistent acne, eczema, unexplained rashes, non-healing areas or changes to a mole should be assessed by a GP, pharmacist or dermatologist. Nutritional support can complement appropriate care but should not replace medical diagnosis or treatment.
Skin Health from Within
We spend a great deal of money trying to improve our skin from the outside. Serums, masks and moisturisers can all have their place, but the skin is not simply a covering. It is a living organ that needs energy, protein, fats, vitamins and minerals for everyday maintenance and repair.
What you eat cannot stop ageing, replace sunscreen or cure a skin condition. However, nutrition provides the raw materials used to form collagen, maintain the skin barrier and support antioxidant defence.
Why Skin Reflects Internal Health
The skin is one of the body’s first lines of defence. Its outer layer helps reduce water loss and protects against irritants, microbes, pollution and physical damage. Beneath it sits the dermis, which contains blood vessels, glands and the extracellular matrix that gives skin much of its strength and flexibility.
Collagen and elastin are important components of this structure. Collagen provides strength, while elastin allows the skin to stretch and return towards its original shape. Fibroblasts continually produce and remodel these proteins.
This process changes with age. Collagen production gradually declines and existing fibres become less well organised. Menopause can accelerate these changes because oestrogen influences skin thickness, hydration and collagen metabolism.
Age is not the only influence. Ultraviolet radiation, smoking, air pollution, poor sleep and persistent stress can all increase oxidative stress or inflammatory signalling. These processes may activate enzymes known as matrix metalloproteinases, or MMPs, which break down parts of the skin’s supporting matrix, including collagen. This helps explain why two people of the same age may have very different skin. Genetics matter, but so does the environment in which the skin has been living.
Nutrition is one part of that environment. It should be viewed as additional support, not edible SPF. Shade, protective clothing and an appropriate broad-spectrum sunscreen remain essential.
There is also growing interest in the gut–skin axis. Gut microbes produce metabolites that interact with the immune system, intestinal barrier and inflammatory pathways. Researchers are investigating these connections in relation to acne, eczema, psoriasis and rosacea. This does not mean every skin flare begins in the bowel. Skin conditions usually have several contributing factors, and microbiome research is still developing. However, it reinforces the idea that skin health does not exist separately from digestion, immune regulation and the quality of the overall diet.
Nutrients That Support Collagen and Skin Structure
No single “beauty food” can transform the skin. Collagen formation is a multi-stage process that depends on enough energy, amino acids, vitamin C and several supporting micronutrients.
Vitamin C has a particularly direct role. It contributes to normal collagen formation for the normal function of skin and contributes to the protection of cells from oxidative stress.
Collagen begins as chains of amino acids. These chains must undergo several chemical modifications before they can form strong fibres. Vitamin C acts as a cofactor for enzymes involved in this process.
Good food sources include peppers, blackcurrants, strawberries, kiwi fruit, citrus fruit, broccoli, Brussels sprouts, watercress, tomatoes and new potatoes.
Vitamin C is water-soluble and sensitive to prolonged cooking, so include a mixture of raw and lightly cooked produce. There is no need for enormous doses. Regular intake from food is more useful than occasionally consuming a very large amount.
Protein supplies the amino acids used to build and repair tissues. Collagen contains high amounts of glycine and proline, but eating collagen does not send it directly to the face. Dietary proteins are broken down, and their amino acids are used according to the body’s priorities.
Include a useful protein source at each main meal. This might be fish, eggs, poultry, lean meat, Greek yoghurt, tofu, tempeh, beans, chickpeas or lentils. Plant-based diets can provide the amino acids needed for the body’s own collagen production. Plants do not contain collagen, but they provide protein alongside vitamin C, polyphenols and other nutrients involved in normal tissue maintenance.
Polyphenols are plant compounds found in berries, cherries, grapes, cocoa, tea, herbs, spices, olives and colourful vegetables.
Laboratory research suggests that some polyphenols can interact with antioxidant defence, inflammatory signalling and enzymes involved in collagen breakdown. Human research is more variable because polyphenols are extensively digested and metabolised.
It therefore makes more sense to eat a wide range of polyphenol-rich foods than to expect one ingredient to reverse skin ageing. Easy additions include berries at breakfast, extra virgin olive oil on vegetables, herbs and spices in cooking, green or black tea, red cabbage, aubergine, apples and a small amount of high-cocoa dark chocolate.
Oxidative Stress and Premature Ageing
Oxidative stress occurs when the production of reactive molecules exceeds the body’s ability to manage them. Reactive oxygen species are not automatically harmful. They are produced during normal metabolism and participate in immune defence and cell signalling. Problems arise when production becomes excessive or antioxidant defences are inadequate.
Ultraviolet radiation is a major external driver of oxidative stress in the skin. Pollution and cigarette smoke can add to this burden. Excessive oxidative stress can affect DNA, cell membranes and proteins, and can activate inflammatory pathways and collagen-degrading enzymes.
The body has its own antioxidant network involving enzymes and nutrients such as vitamin C, vitamin E, selenium, zinc and carotenoids. These do not form an invisible shield. They work as part of a coordinated defence and repair system.
Carotenoids are the yellow, orange and red pigments found in carrots, tomatoes, peppers, pumpkin, watermelon and leafy greens. Several can accumulate in the skin. Human feeding studies suggest that regularly eating carotenoid-rich foods may modestly increase resistance to UV-induced redness. This effect develops gradually and is far weaker than sunscreen or protective clothing.
Oxidative stress can also be generated internally. Persistently high blood glucose may increase oxidative stress and promote the formation of advanced glycation end-products, or AGEs. Glycation occurs when sugars react with proteins. When this affects long-lived proteins such as collagen, fibres may become stiffer and more resistant to normal repair. This does not mean sugar must be eliminated or that one pudding ages the face. The repeated metabolic environment matters more than a single food.
Meals built around protein, vegetables, fibre-rich carbohydrates and healthy fats generally produce a steadier glucose response than meals dominated by refined carbohydrates.
Everyday Foods for Healthier Skin
A skin-supportive diet does not require specialist powders or a restrictive “cleanse”. It looks much like a varied Mediterranean-style pattern.
Aim to include:
Eat enough overall. Chronic under-eating can reduce intake of protein, essential fats and micronutrients. Look after the gut by increasing plant diversity gradually and according to tolerance. Fermented foods may suit some people but are not compulsory.
Drink regularly, but remember that litres of water will not erase dry skin or wrinkles. Limit smoking and excessive alcohol, prioritise sleep and seek medical advice for persistent acne, eczema, unexplained rashes or changes to a mole.
Healthy skin is not created by one perfect meal, and it is not ruined by one imperfect one.

Top Tips: Travel-Friendly Food Swaps for a Healthy Gut
Travel food can be a bit of a lottery. Sometimes you find a lovely little café with fresh food, proper coffee and plenty of delicious options that you can photograph and remember when you get home. Other times, you are standing in an airport queue, tired, hungry and wondering whether lunch is going to be a packet of crisps, a giant muffin or a slightly limp sandwich.
When you have a sensitive gut, this can feel even more difficult. You may be trying to avoid bloating, reflux, constipation, loose stools or blood sugar dips, but you also do not want to turn your holiday into a set of food rules.
The good news is that supporting your gut while travelling does not have to mean packing a suitcase full of chia seeds or refusing every ice cream, pastry or restaurant meal. It is usually about making a few simple swaps that help keep your digestion, energy and appetite steadier.
Think of this as adding a little structure around the edges, so you can enjoy your time away without your gut feeling completely abandoned.
Why Travel Often Disrupts Digestion
Your gut is surprisingly sensitive to routine.
At home, you may eat at fairly similar times, drink from your usual mug, have access to foods you know you tolerate, and move around in a way your body recognises. When you travel, that rhythm changes quickly.
You may skip breakfast to get to the airport, drink more coffee than usual, sit still for hours, snack instead of eating a proper meal, eat later at night, drink less water and have a bit more alcohol, or rely on foods that are lower in fibre and protein. None of this is “bad”, but it can make digestion feel more unpredictable.
For some people, travel leads to constipation because they are moving less, drinking less and ignoring the urge to go. For others, the combination of rich food, alcohol, unfamiliar ingredients, stress and disrupted sleep can trigger bloating, reflux or loose stools.
If you have IBS, this can be even more noticeable. IBS symptoms can be affected by meal timing, stress, caffeine, alcohol, fizzy drinks, fibre type, fat content and individual food triggers. This is why a travel day that looks “not that bad” on paper can still leave you feeling uncomfortable.
The aim is not to eat perfectly. It is to make a few swaps that reduce the overall digestive load.
Practical Swaps for Airports, Hotels and Road Trips
One of the easiest ways to support your gut when travelling is to avoid going into the day underfed and over-caffeinated.
A common travel pattern is coffee at home, coffee at the station, something sweet at the airport, then a long gap before a very large meal. This can leave you tired, wired, bloated and craving more quick energy by the afternoon.
A better swap is to aim for protein earlier in the day. If you are at the airport, look for eggs, Greek yoghurt, smoked salmon, chicken, hummus, cheese, nuts, seeds or a more substantial sandwich or salad with protein.
If you are leaving early, even a quick breakfast at home can help: yoghurt with berries and seeds, eggs on toast, overnight oats with protein, or a smoothie with protein powder if you tolerate it.
If your usual travel choice is a pastry or muffin, you do not need to ban it. But you may feel better if you pair it with something more sustaining. For example, have a croissant with Greek yoghurt or eggs rather than on its own. Have fruit with nuts rather than fruit alone. Choose a sandwich with chicken, tuna, egg or hummus instead of a plain cheese baguette with very little fibre or colour.
At hotel breakfasts, the same principle applies. Start with protein, then add plants and carbohydrates you tolerate. Eggs with tomatoes and mushrooms, yoghurt with berries and seeds, porridge with ground flaxseed, or smoked salmon with sourdough may all be more supportive than a plate made entirely of pastries, juice and coffee.
For road trips, the biggest issue is often convenience food. Service stations are improving, but they still make it very easy to graze on crisps, sweets, chocolate bars and fizzy drinks. These foods are not forbidden, but if they become the whole meal, your gut and energy may not thank you.
A simple road trip swap is to pack one “proper food” option before you leave. That might be a chicken wrap, oatcakes with cheese, a boiled egg pot, hummus with crackers, leftover frittata, yoghurt with berries, or a small cool bag with fruit, nuts and a protein option. You can still stop for coffee or enjoy something fun, but you are not relying entirely on what is available next to the petrol pumps.
Protein and Fibre on the Go
Protein and fibre are two of the most useful travel nutrition anchors.
Protein helps meals feel more satisfying and supports steadier energy. Fibre supports bowel regularity, gut microbiome diversity and stool consistency, although the type and amount of fibre matters if you have IBS or bloating.
The problem is that many travel foods are high in refined carbohydrates but low in protein and fibre. Think pastries, muffins, crisps, sweets, white bread sandwiches, biscuits and sugary drinks. These can be convenient, but they may leave you hungry again quickly or more prone to energy dips. A better approach is to build a “protein plus fibre” habit.
Instead of crisps on their own, try oatcakes with cheese, hummus with crackers, roasted chickpeas if you tolerate legumes, or nuts with fruit.
Instead of a sweet cereal bar, try a simple protein bar with recognisable ingredients, Greek yoghurt with berries, or a small bag of trail mix.
Instead of a white bread sandwich with very little filling, choose one with chicken, tuna, egg, smoked salmon, falafel or hummus, ideally with salad or vegetables.
Instead of fruit juice, choose whole fruit and water. Whole fruit provides fibre and tends to be more filling than juice, which can deliver a lot of sugar quickly and may loosen stools in some people.
If you are prone to bloating, be mindful that more fibre is not always better on a travel day. Suddenly eating lots of raw vegetables, beans, bran bars or dried fruit can make symptoms worse. Soluble fibre is often gentler. Oats, chia, ground flaxseed, berries, peeled fruit, potatoes and carrots may suit some people better than large raw salads or high-bran products.
Smarter Snack Choices for Energy
Snacks can be really useful when travelling, especially if meals are unpredictable. The issue is not snacking itself. The issue is relying on snacks that give you a quick lift, then leave you hungrier, more tired or more bloated an hour later.
A good travel snack usually has at least one of three things: protein, fibre or healthy fats. Even better if it has two.
Some practical options include oatcakes with nut butter, rice cakes with cheese, nuts and fruit, Greek yoghurt, boiled eggs, hummus with crackers, roasted edamame if tolerated, a simple protein bar, biltong, olives, avocado pots, or a small homemade flapjack with oats and seeds.
It is also worth watching the “health halo” snacks. Many bars, protein snacks, vegetable crisps and gluten-free travel foods are marketed as healthy, but may be high in sugar, sweeteners, emulsifiers, polyols or additives that do not suit a sensitive gut. Some sugar-free sweets and bars contain sugar alcohols such as sorbitol, xylitol or maltitol, which can trigger gas, bloating or diarrhoea in people with IBS.
A simple label check can help. Look for a shorter ingredient list, a decent protein or fibre content, and ingredients you recognise. If a product has a long list of syrups, sweeteners, gums, flavourings and claims on the front of the packet, it may not be as gut-friendly as it looks.
Preparing Ahead Without Obsessing
A little planning can make travel much easier, but there is a fine line between being prepared and becoming anxious about food.
The aim is not to pack every meal or avoid all local food. One of the joys of travel is eating differently. But if your gut is sensitive, it can help to take a few familiar options with you, so you are not completely dependent on airports, service stations or hotel buffets.
Before you travel, think about your likely pinch points. Is it the early start? The airport wait? The long car journey? The hotel breakfast? The late dinner? The moment when everyone else wants cocktails and crisps but you have not eaten properly since 10am?
Once you know your weak spot, you can plan around it.
For an early start, prepare breakfast the night before. For a long journey, pack a protein-rich snack and water. For a hotel breakfast, decide in advance that you will start with protein. For a day trip, take something familiar in your bag. For a hot day, keep hydration and electrolytes in mind.
If you are travelling with IBS, SIBO-type symptoms, reflux or a very sensitive gut, it may also help to keep your food choices simpler for the first day or two. Give your body time to adjust before you add in all the rich food, alcohol, late nights and new ingredients at once.
You can still enjoy your holiday. You may just enjoy it more if your gut is not in crisis by day three.
And if your gut is making going away a worry, it doesn’t have to be that way. Why not book in a call to find out more?
