Happy Tummy Foods

Some foods are excellent for supporting our digestion and here are some of my favourites that I suggest to clients on a regular basis:

Cruciferous vegetables

These smelly veg bring amazing health benefits on a number of different levels. Since we’re talking about foods that are helpful for your digestion, you should know that they contain compounds called glucosinolates, which are fermented by bacteria and used as fuel. They are prebiotic.

Examples:

Bok choy, broccoli, Brussels sprouts, cabbage, caulifiower, kale , rocket, spring greens, watercress.

Fermented foods

Fermented foods have a long tradition in some parts of the world, especially Asia, Africa and Eastern Europe. Bacteria (and sometimes beneficial yeasts) might be involved in the process and the result is an increase of good bacteria in the foods. You’ve probably heard of live or ‘bio’ yoghurt.

Some of these other probiotic foods might sound peculiar and a little ‘advanced’ for most regular people. However, they are now commonly found on supermarket shelves (you'll find them in the world foods aisle where the Oriental products are) and, while they might not be the kind of product you would usually go for, it is always worth experimenting. Kimchi, in particular, is often combined with chilli and other flavours and is far tastier than its name might suggest.

Examples include yoghurt, pickles (gherkins), sauerkraut, kimchi (fermented cabbage), tempeh (fermented soya beans), natto (fermented soya beans), miso soup (fermented soya beans), tamari soy sauce, buttermilk, some cheeses like cottage cheese, gouda, mozzarella and cheddar.

Fermented drinks

Like other fermented products, these were once only found in health food shops and were perhaps the prevail of people who ate a very clean and unprocessed diet. 

These were a secret waiting for the masses to discover. Often flavoured with fruits, they really are delicious and do not taste 'worthy'. You'll find them in the chilled drinks section in most supermarkets.

Kombucha (fermented tea - sweet and fizzy but without sugar) and kefir (fermented dairy drink very much like a yoghurt drink) are examples.

The only way you’ll know if it’s for you is to try!

Fibre

Fibre is one of the best things to eat to support healthy digestion. Fibre is described as being either insoluble or soluble.

This is part of the plant wall in fruit and veg. It’s indigestible so it passes right through your system, sweeping up toxins and other waste products as it goes, and keeping you regular. The undigested fibre is also fermented by gut bacteria, producing the beneficial short chain fatty acids mentioned earlier.

YOU CAN FIND INSOLUBLE FIBRE IN:

Fruit and veg, beans and lentils, oats and wholegrain foods like brown rice and wheat.

This can be partially digested and is well-celebrated for its ability to reduce cholesterol in the blood and normalise blood sugar levels.

YOU CAN FIND SOLUBLE FIBRE IN:

Oats, veg, fruit (especially apples, pears, berries, and citrus fruits), beans and lentils.

Anti-Microbial Foods

Some foods exert a natural antibiotic or anti-fungal effect and can be useful for keeping nasties like pathogenic bacteria or unwelcome yeasts at bay.

These include caprylic acid found in coconut. Coconut oil is also a very good oil to use in cooking, especially at high temperatures.

Garlic contains the active ingredient allicin, which has historically proven itself to be an effective killer of both bacteria and viruses, making it a great immune-boosting ingredient. Use it raw wherever possible.

Olive oil – the oleic acid has anti-bacterial properties. Use it generously to dress salads and veg.

And we can’t have a list of the foods to add in, without looking at what we need to avoid for a happy tummy:

Sugar and refined carbohydrates

In same way there are things your digestive system loves, there are things it will not love you for. Sugar. That’s the number one thing to avoid, plus anything that contains added sugar.

Other things your tummy is not fond of include highly refined products like white rice, pasta, pastry and snacks like crisps and biscuits.

Fix Your Digestion Naturally

There are few things worse than tummy troubles. If your digestive system doesn’t work as it should, the result might be pain or discomfort right through to downright embarrassment at the gurgly noises and bad smells your body produces. It doesn’t have to be that way and, as a nutrition practitioner, I am always amazed by how long some of my clients have been trying to muddle through before they seek my help.

What scientists now call the ‘microbiome’ is a parallel universe of all kinds of different microorganisms running all through your digestive tract, that runs from your mouth to… well, the other end.

Most of these organisms are bacteria, and there are lots more of these than there are cells in your body - about ten times as many. The balance of the bacteria in your digestive system has implications for your health in general and not just your innards. In short, it’s important to have the right kinds of bacteria in the right places. It matters that the ratio of good to bad bacteria works – when you’re out of balance (there are more unfavourable bacteria and other microorganisms) nutritionists call this ‘dysbiosis’.

Dysbiosis can result in your digestive system becoming a more favourable environment for yeasts like candida or parasites. There are some places you don’t really want many bacteria, whether good or bad, like in the small intestine. Your body really should do a daily swoosh of all bacteria from the small intestine down to the colon (it's called the Migrating Motor Complex).

There are many reasons why this might happen – like having had food poisoning in the past – and the result is that the bacteria left behind feast on the food you’re eating, causing bloating, wind, feelings of nausea, diarrhoea and constipation (or a combination of the two). Essentially, all those things you might be linking to your irritable bowel syndrome (IBS).

I’m going to be straight with you and say that the ideal situation is that you bring your digestive problems to me, and that we talk about getting to the bottom (excuse the pun) of exactly why your system isn’t working the way it should, and this usually involves some testing. When you’re ready to prioritise your health, you know where I am.

In the meantime, here are my top 5 tips to help to fix your digestion

1. Use your senses

The first step in the digestive process is often overlooked but it's a really important one. Known as the cephalic phase, it’s triggered when you see or smell food. You are literally whetting your appetite. When you start thinking about the lovely meal you are going to prepare, you are getting your digestive juices flowing. The enzymes in your saliva help you break down your food more easily so, when the time comes, your body is actually ready to start digesting food before you have even cut the first slice – never mind actually putting anything in your mouth.

It may sound an incredibly simple step – and it is – but these days we are often so busy that we don’t make the time to think about our food in this way. If you find you're always eating on the go, throwing a sandwich down your neck at your desk or having a TV dinner, this is a vital step you are missing out on. One trick is to be mindful and try and spend a few minutes thinking about your tasty lunch before you eat it to get the digestive juices going.

2. Chew Your Food

Your stomach does not have teeth! Chewing your food is the second phase of digestion, and it’s key when it comes to good gut health. With proper chewing, you are mechanically breaking down the food into smaller pieces, so that there’s a greater surface area and the digestive enzymes can get to work more easily, doing their job. And the bad news?

If you’re not chewing properly, it’s highly likely that you’re not digesting your food properly. And that means you won’t be absorbing vital nutrients either. Not chewing also means the food you eat takes much longer to break down and, as it hangs around in your digestive system, it can start to ferment, causing uncomfortable wind, gas and bloating. Don’t worry about chewing a certain number of times – that all depends on what you are eating and various other factors.

Instead try this test: chew your food enough so that if someone asked you to spit it out, they wouldn’t know what you had been eating. Another sign you need to chew more is if you start to see undigested food in your stools.

3. Balance Your Stomach Acid

Sales for heartburn tablets are skyrocketing because so many people wrongly assume that their digestive troubles are because of too much stomach acid. What nutritionists like me find more frequently in the clinic is the total opposite! Getting older, stress and some over-the-counter medications can make your stomach acid levels drop to the extent that you don’t produce enough to digest food sufficiently.

Why is this important? The stomach acid you produce not only kills any bacteria in the food you are eating, but it also breaks down the protein in your meal. If you’re not properly digesting the protein element in food, it can start to ferment, creating gases that force up the oesophagal sphincter muscle (a type of muscle flap) and what little stomach acid there is can escape. So that burning feeling, especially if accompanied by smelly gas, can be a sign your digestion isn’t working as well as it should be.

One solution is to have a teaspoon of apple cider vinegar before each main meal. It’s important you choose apple cider vinegar with the ‘mother’ rather than one you can buy in the supermarket (that’s for your chips).

There are people who genuinely produce too much stomach acid and, if you try the apple cider vinegar trick and it seems to make things worse, you can neutralise the acid by taking a little bicarbonate of soda.

4. Take a digestive enzyme supplement

Digestive enzymes break down your food into nutrients so your body can absorb them. But as you age, you naturally produce fewer of these helpful enzymes. You can counteract this by increasing your intake of foods that are higher in them – eating pineapple or papaya before a meal can help.

If you aren’t a fan of these fruits, instead try a digestive enzyme capsule (available from health food shops), which will give your system a gentle boost to help it do its job properly.

5. Take time out

Not eating is almost as important for your health as eating. It’s important to space out your meals so the digestive system actually gets a chance to rest. This might require some self-discipline if you’re a frequent grazer.

Eating every 4-6 hours is a good benchmark to aim for and gives the body enough time to completely digest the previous meal and have a break before you put it to work again.

Of course, there will be days when your eating routine falls out of whack, but don’t beat yourself up. Just try and get back on track the following day.

What exactly is IBS?

Irritable Bowel Syndrome is a problem I see daily in clinic and it is problematic on many different levels. 

If you have been diagnosed with this condition, you may well have been suffering with it for years and, while a diagnosis can – at first– offer comfort in finally having a recognised problem, the satisfaction is short lived because often that’s where all support ends, and you’re left no further forward in actually fixing what the problem is. 

The difficulty begins because IBS is essentially meaningless; it’s a catch-all term used to encompass a huge variety of digestive issues. If you’re serious about getting to the bottom of the problem (no pun intended), I’m happy to discuss your symptoms and help find a way forward. You can book a free IBS health check with me by clicking here.

 

In my experience, it’s likely to be one of the following five conditions:

1 SIBO (small intestine bacterial overgrowth)

Around 60% of people with IBS will have SIBO. Though you might have heard about good (and bad) bacteria in the gut, really what experts are talking about is the balance of bacteria in the large intestine: the colon. 

The small intestine shouldn’t have very much bacteria at all, and the each day the body should perform a flush to sweep bacteria from the small intestine and into the large intestine. This flush is called the ‘migrating motor complex’. 

For a huge variety of reasons (historic food poisoning being the most common, but also low levels of stomach acid, or adhesions may play a role, among others) the bacteria are not swept away. The trouble is that these bacteria can ferment the food in your small intestine, causing gas, belching, bloating, pain and a variety of other symptoms, including constipation and/or loose stools, and even anxiety. 

A simple breath test can establish which gases are present, and we can devise an action plan based on your results. 

2 Lactose intolerance

This is when your body is not able to tolerate lactose, a type of sugar found naturally in milk and other dairy products. Essentially, bacteria in your intestine feed on these milk sugars, leading to a host of IBS symptoms, like bloating and gas, nausea, constipation or diarrhoea. 

It can go hand in hand with other digestive complaints, such as coeliac disease or increased intestinal permeability (‘leaky gut’). Lactose intolerance can be diagnosed via a simple at-home breath test. 

3 Fructose malabsorption

The symptoms are very similar to lactose intolerance. Fructose (which is found in fruit, honey and many processed foods) is a sugar, which, like lactose, is digested in the small intestine. 

Some people cannot absorb fructose, and what is not absorbed is fermented by intestinal bacteria, causing bloating, cramping, gas and distension of the stomach. 

You might also experience brain fog and headaches. A breath test will diagnose the condition. 

4 Dysbiosis

This is an imbalance in the levels of beneficial (good) and pathogenic (bad) bacteria in the large intestine or colon. This is now common due to overuse of antibiotics and alcohol, an increase in high sugar diets, and stress.

Symptoms can vary from a sluggish bowel or diarrhoea, pain, bloating and flatulence, to chronic bad breath, joint pain, fatigue, and food sensitivities.

Dysbiosis is also implicated in a variety of health conditions like diabetes, heart disease and obesity. A stool test can help establish whether your gut bacteria are out of balance, along with a host of other markers that might be useful in getting to the root of your digestive problems. 

 

5 Yeast overgrowth

Where the gut environment becomes out of balance (due to dysbiosis), yeast can thrive. 

Diets high in sugar feed the yeast – although if you think you might have a yeast overgrowth, it’s worth noting that long-term yeast problems can mean that the yeast cells are pathogenic or disease causing, and that the yeast has switched its metabolism to also be able to digest protein and fat. Symptoms of yeast overgrowth include recurring thrush, gas or bloating, fatigue, bad breath, cravings for sweet foods, joint pain and brain fog. 

A stool test can establish the presence of candida or other yeast overgrowth.

Did you know that up to 80% of your immunity to germs and disease is in your digestive system? The mucosa-associated lymphoid tissue (MALT) in the gut is part of the first line of immune defence so getting the right balance between beneficial or ‘good’ gut bacteria and the ‘bad’ or potentially pathogenic bacteria is key.

The gastrointestinal tract houses a diverse community —thousands of microorganisms, encompassing bacteria, fungi, viruses, and various microbes collectively known as the gut microbiome. Within this delicate ecosystem, certain microorganisms correlate with favourable health outcomes, while others are associated with less desirable effects.

Optimal gut health, characterized by a rich diversity of beneficial bacteria, is integral to the maintenance of a robust immune system. It assumes a key role in modulating immune responses, ensuring a correct reaction to injury or infection without compromising healthy tissue.

The intricate interplay between gut microbiome and immune system functions bidirectionally. Similar to how the immune system exerts influence on gut health, the gut microbiome significantly impacts immune responses, including specific types of inflammation.

Distinguishing between acute and chronic inflammation is imperative. Acute inflammation, such as our bodies’ reaction following physical injury, is a natural part of our body's self-care mechanism. Conversely, chronic inflammation represents a prolonged and detrimental immune response, associated with heightened risks of conditions such as obesity, heart disease, and type 2 diabetes.

Research shows us that the gut microbiome serves as a central conduit, linking chronic inflammation to these chronic conditions.

Turning attention to our nutrition, we know that an individual approach is essential, as no microbiome is the same! However, there are general principles which underpin a good, diverse microbiome – and thus allowing us to support good working of the body’s immune system.

Emphasizing plant-rich diets, particularly those rich in prebiotics found in foods like asparagus, onions, leeks, garlic, legumes, and whole grains, are a great place to start. Prebiotic foods help to feed the friendly bacteria in our guts.

In addition to this, incorporating probiotic-rich foods is another foundational step. Probiotics, living microorganisms found in fermented foods such as yoghurt, kefir, kimchi, sauerkraut, aged cheddar, and kombucha, play a role in enhancing gut microbiome diversity and fostering the proliferation of beneficial microorganisms. Being consistent in consuming these types of foods is key.

In summary, the symbiosis between gut health and the immune system is like a symphony, orchestrated by the gut microbiome. Understanding and nurturing this relationship, particularly through good diet choices, is foundational to a good immune system.

Is your IBS driving you crazy?

Bloating, gassy, cramps, heavy, uncomfortable? One minute you can’t go to the loo and the next minute you can’t get off it. 

The likely cause is Irritable Bowel Syndrome (IBS). It’s incredibly common. According to Guts UK, a charity set up to promote awareness of and funding for digestive problems, it affects up to a third of people at some stage or another and it is one of the main reasons people visit their doctor.

Unfortunately, according to the NHS, there’s not a lot you can do. The official view is that it’s a lifelong problem that no one really understands and that there’s no cure for (although over-the-counter medicines can help symptoms). So sorry, move along and deal with it yourself. 

As nutrition professionals will tell you, there IS hope. A consultation with a nutrition professional specialising in digestive health will be able to, in the first instance, provide some natural solutions that are likely better than taking over-the-counter medication AND your nutritionist will be able to work with you to find the root cause. This will enable you to get to the bottom of what is causing the symptoms of IBS (excuse the pun), and then you can take steps to fix it.

One of the most common causes of IBS is SIBO (small intestinal bacterial overgrowth), which accounts for 60##plus## of IBS cases. This describes a condition where bacteria manage to grow and thrive in the small intestine. It’s not a question of ‘good’ or ‘bad’ bacteria. There shouldn’t really be many there at all.

It might be that you have a lactose intolerance. This is when your body is not able to tolerate lactose, a type of sugar found naturally in milk and other dairy products, leading to a host of ‘IBS symptoms’. It might similarly be fructose malabsorption. Again, some people are not able to absorb fructose and symptoms are very similar to lactose intolerance. 

Dysbiosis is an imbalance in the levels of beneficial (good) and pathogenic (bad) bacteria in the large intestine or colon, potentially caused by the overuse of antibiotics or alcohol, an increase in high sugar diets, and stress. 

Or you might have a yeast overgrowth. Simply, the gut environment gets out of balance (due to dysbiosis) such that unwelcome yeast can thrive.  

None of these are pressing issues for regular doctors because there is often not the NHS testing or the framework for treatment of these problems. In some cases, digestive problems can be tricky to solve, and it almost always involves a lot of detective work. But if your symptoms are hampering your life in a significant way, I want you to know that there ARE things you can do. Although IBS might be very common, it is not normal to experience the symptoms you do.

What can I do about my IBS now?

There are some simple tricks you can put into practice today and that might make enough of a difference to help you get your life back on track. I’m going to tell you what they are in a moment.

I also want you to consider the degree to which your symptoms bother you. Are you satisfied with just covering up the symptoms and hoping for the best? That might be enough for you. If it isn’t, please book yourself in for a free 30-minute digestive health call to get an idea of what you can do right away and what might be possible for you. 

10 ways to improve your digestion

The following suggestions are very basic but surprisingly effective at improving symptoms of digestive distress. 

DO

• Try a cup of hot water or ginger tea before meals to stimulate digestion.
• Apple cider vinegar (with the ‘mother’) also works – take 1tsp before a meal.
• Think about your food before eating it – the thought and smell kickstarts the digestive process.
• Make sure you’re chewing properly. If you had to spit out the mouthful, no one should be able to tell what you’ve been eating. 
• Try a few cubes of pineapple or papaya before a meal. These contain enzymes that can boost your digestion. You might also consider taking a natural digestive enzyme supplement from a health food store to support your body’s natural digestion process.
• Take a 15-minute walk after eating if you can. This lowers blood sugar levels and improves digestion (see, your granny was right).

 

DON’T

• Eat at your desk at work. Getting up and out is important for so many reasons. In this case, checking emails while you are also eating may have you gulp down your food or not chewing properly. Neither are good for your digestive health. 
• Try to eat on the go or when you’re stressed out. You won’t digest your food properly or absorb the nutrients. This is the quickest way to get heartburn.
• Don’t eat fruit after a meal. Fruit likes a quick passage through the digestive system. It can get stuck behind other foods that are digested more slowly and then ferment, causing gas. 
• Don't drink too much water or other fluids with your meal as this dilutes the stomach acid needed to digest your food properly.

If you’re sick of feeling bloated, gassy, crampy, or going to the loo too often (or not often enough), book in for a free 30-minute digestive health mini consultation. You can do that by clicking this link here.

Probiotics and prebiotics. What are they and why are they important?

You’ve probably heard people talk about ‘good’ and ‘bad’ bacteria and that we want to have more ‘good’ bacteria because this has a positive effect on your health. I’ll bet you may also have a conceptual idea that probiotics will help you, and perhaps you’ve seen little bottles of probiotics advertised as the saviour of your health. Today I want to let you know why this all matters, so that you can make the best choices for your health. 

Good v bad bacteria

When we talk about bacteria in the gut, we are usually talking about bacteria in the large intestine, the colon. Your ‘microbiome’. The microbiome is a parallel universe of all kinds of different microorganisms running all through your digestive tract, that runs from your mouth to… well, the other end. 

Most of these organisms are bacteria, and there are lots more of these than there are cells in your body - about ten times as many. The balance of the bacteria in your digestive system has implications for your health in general and not just your innards. In short, it’s important to have the right kinds of bacteria in the right places. It matters that the ratio of good to bad bacteria works – when you’re out of balance (when there are more unfavourable bacteria and other microorganisms) nutritionists call this ‘dysbiosis’.

These microorganisms play a crucial role in maintaining overall health, as they help to break down food, make vitamins, regulate your immune system, and prevent the growth of harmful pathogens. When we think about the gut, consider we want a balance between the good and bad microorganisms, a victory of ‘good’ over ‘bad’ bacteria and yeasts, and so on. 

Research tells us the composition of the microbiome can vary widely from person to person, and that changes in the microbiome may be associated with a variety of health conditions, including inflammatory bowel disease, obesity, and diabetes. As a result, there is growing interest in understanding more the microbiome and its role in health, and in developing strategies to maintain or modify the microbiome for therapeutic purposes. As a nutrition practitioner, it’s one of the areas that fascinates me and I spend a lot of time in clinic talking to people about how they can use food and supplements to support the health of their microbiome. 

(As an aside, although the word microbiome is most commonly associated with the gut, in reality, your microbiome also refers to other parts of the body, such as the skin, mouth, and reproductive tract.)

One of the ways you can keep a healthy gut environment is to tackle any digestive problems you might be struggling with (ask me if you need help), eat the kinds of foods our body really needs and (potentially) take supplements to help ensure the bacterial balance in your gut microbiome stays positive in spite of what 21st century living may throw at it. Eating probiotic foods and prebiotic foods can help.

Probiotic foods

Probiotic foods are foods that naturally contain live microorganisms like bacteria or yeasts. They are often referred to as "functional foods" as they provide nutritional benefits beyond basic nutritional needs. Think of these as providing your body with additional healthful bacteria. 

Some of the most common probiotic foods include:

• Yoghurt: Yoghurt is made by fermenting milk with bacterial cultures, typically Lactobacillus bulgaricus and Streptococcus thermophilus. Some yogurt products also contain additional probiotic strains, such as Lactobacillus acidophilus and Bifidobacterium lactis.
• Kefir: Kefir is a fermented milk drink that is made by combining milk with kefir grains, which contain a mixture of bacteria and yeasts. Kefir is rich in probiotics and may also contain other beneficial compounds, such as vitamins and minerals.
• Sauerkraut: Sauerkraut is a fermented cabbage dish popular in Europe that is made by combining shredded cabbage with salt and allowing it to ferment for several days. The fermentation process produces lactic acid, which gives sauerkraut its distinctive sour taste and also serves as a natural preservative.
• Kimchi: Kimchi is a spicy Korean dish that is made by fermenting vegetables, typically cabbage, with a mixture of spices and seasonings. Kimchi is rich in probiotics and may also contain other beneficial compounds, such as antioxidants and anti-inflammatory compounds.
• Miso: Miso is a Japanese condiment that is made by fermenting soybeans with a type of fungus called Aspergillus oryzae. Miso is typically used as a seasoning in soups and other dishes and is rich in probiotics and other beneficial compounds, such as antioxidants and vitamins. You can buy miso soup to drink as a snack and also miso paste, which you might use in cooking, from many supermarkets. 

What about probiotic drinks?

You will undoubtedly have seen mass-produced and heavily advertised drinks like Actimel and Yakult on supermarket shelves. Unfortunately, many of the popular ones do not have enough bacteria and/or the bacteria do not survive the harsh digestive environment in the gut, therefore do not have an impact. Just swallowing something ‘good’ is not enough. Often these additionally either have added sugars or sweeteners to make them palatable, which is not that great for the gut. My view: go for the more traditional form of fermented foods.

Probiotic supplements

You’ve likely also have seen probiotic supplements, even on supermarket shelves and wondered whether you should take one. 

Unfortunately, a supplement cannot replace a good diet, but it can help provide targeted support. If you have digestive problems, let’s have a chat about what we can do to help. Since everyone is different and we all have a unique microbiome, truly targeted support can look like finding specific strains of bacteria to support certain conditions (some strains are great for supporting low mood, others are helpful for hormone balance, and so it goes on). These are often not the kinds of products without professional recommendation. 

That said some of the key beneficial bacteria that can help include lactobacillus (acidophilus and rhamnosus) and the bifidobacteria group (breve, longum, lactis). Bottom line, what will most benefit you very much depend on the specific symptoms or conditions you are dealing with. And I would *always* look at diet before supplementation.

About prebiotics

Prebiotics are a type of dietary fibre that are not digested in the small intestine, but instead reaches the large intestine where they serve as a food source for beneficial gut bacteria. So, while probiotics provide additional bacteria, prebiotics feed the bacteria that are already there and help promote the growth and activity of specific types of bacteria that are considered beneficial for health.   

Some common types of prebiotics include inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS). These prebiotic fibres are found naturally in many plant-based foods, such as bananas, onions, garlic, leeks, asparagus, artichokes, and whole grains.

Cruciferous veggies are also very helpful for your digestion, you should know that they contain compounds called glucosinolates, which are fermented by bacteria and used as fuel. They are also prebiotic. 

Examples are: Bok choy, broccoli, Brussels sprouts, cabbage, cauliflower, kale and spring greens.

Prebiotics have been shown to have a variety of health benefits, including improving digestion, boosting the immune system, reducing inflammation, and improving the absorption of certain nutrients. Additionally, research suggests that prebiotics may help reduce the risk of certain health conditions, such as type 2 diabetes, heart disease, and colorectal cancer.

It is important to note that while prebiotics are beneficial for health, they can also cause digestive discomfort in some people, particularly when consumed in high amounts. Anyone with IBS, for example, should approach some of these foods with care. What lurks behind the majority of cases of IBS is bacteria in the small intestine, where we don’t really want it (large intestine, yes, small intestine, no). Your body really should do a daily swoosh of all bacteria from the small intestine down to the colon (called the Migrating Motor Complex) but for a variety of reasons that might not occur. What can then happen is the bacteria in the small intestine can feast on these lovely prebiotic foods, causing gas, bloating and discomfort. That’s not me telling you don’t eat these foods but, if you have digestive problems, start with small quantities until you work out what your body can tolerate. 

You can also buy prebiotic supplements like FOS but I wouldn’t advise these unless you are working with a nutrition professional. They can be really helpful in a digestive health programme but only if you know what you are doing and which specific products to buy. 

A healthy microbiome 

5 important things your gut bacteria do for you:

1 Kill bugs and hostile bacteria 

These can cause unpleasant symptoms or disease – like the ones that cause food poisoning or stomach ulcers.

2 Boost your immunity

60% of your immunity is in your gut and the immune tissue in your digestive system is very sensitive to bacterial activity. The good bacteria also encourage the body to make a particular kind of antibody that stops you getting sick.

3 Improve digestion

Some bacteria help you break down particular foods and even help with the muscular contractions that move food through your system – thus keeping you regular.

4 Make vitamins & help you absorb nutrients better

Your gut bacteria are responsible for making many B vitamins, and these same bacteria help you absorb minerals in the food you eat better.

5 Protect against disease

Some bacteria produce enzymes that turn the fibre you eat into short chain fatty acids (SCFA). This is interesting because these SCFAs can help protect against heart diseases by regulating cholesterol and having a positive impact on fats in the blood. A particular type of SCFA called butyrate has been shown to be protective against cancer.
