Busting 8 common gut health myths

Our gut is as individual as we are, but for many people, talking about gut health is a little taboo. While we can understand that discussing the ins and outs of our gut health may feel a little embarrassing, it’s far from it.

In fact, it’s this taboo – in addition to a lack of understanding around gut health and an inability to break bad gut habits — that means 57% of people don't take their gut health as seriously as they should. But we’re here to change this, so without further ado, let’s get into it.

Gut health 101

Simply put, gut health refers to the overall health of the digestive system. This includes the stomach, small intestine, large intestine and all the parts of our body responsible for breaking down food into nutrients.

Sometimes, things like constipation, diarrhoea can be signs of an unhealthy gut. But there’s no sure way to tell if you have a healthy gut.

Why is gut health important?

Believe it or not, the gut is home to trillions of live bacteria and other microorganisms (mainly found in the large intestine and collectively known as the gut microbiome). Made up of both good and bad bacteria, the microbiome works to help keep us healthy. The balance and diversity of different gut bacteria is unique to each individual and linked to a range of essential bodily functions.

Here’s just a handful of roles that gut bacteria plays:

• They support immune health by helping to train the immune system (70% of immune cells are found in the gut!)

• They help our bodies digest food, such as fibre, and absorb nutrients to support the body’s daily functions

• They help protect us from harmful bacteria

• They combine essential vitamins including K and B12

8 common gut health myths, busted

When it comes to our gut health, there is no magic potion or quick fix. Gut bacteria are as unique as we are, so what may work for one person might not work for another. The general rule of thumb is to stick to a well-balanced diet, an active lifestyle, get plenty of sleep and keep hydrated. All of these can help contribute to your overall wellbeing.

What we do know is that there’s a lot of myths and theories out there on gut health – think old wives tales. This, along with one-size-fits-all answers means it can be hard to digest (pardon the pun) what’s true and what’s false. So, with this in mind, let’s get into busting the most common myths…

1. Serotonin (the feel-good hormone) is only produced in the brain

Serotonin is a chemical found naturally in the body that functions as a neurotransmitter (neurotransmitters are the body's chemical messengers). And while serotonin is often referred to as ‘the feel-good hormone’ as it helps regulate moods, what many people don’t know is that 95% of serotonin is actually produced in the gut.

And it makes a lot of sense. Think back to a time where you’ve experienced a butterfly feeling in your stomach, or when you’ve based an important decision on a gut instinct, or perhaps you’ve suffered from an upset stomach during a stressful time.

This all comes down to the bi-directional communication between the gut and brain, known as the gut-brain axis. In simple terms, they’re connected both physically through the vagus nerve (one of the biggest nerves connecting your gut and brain), as well as chemically through neurotransmitters, such as serotonin. 

This means that the gut plays a crucial role in supporting your moods. Want to know more? Find out more about the connection between the gut microbiome and your health.

2. You should have a bowel movement every day

Despite this being part of a daily routine for many, talking about toilet habits can often feel a little taboo – but it needn’t be. We’re here to lift the lid on bowel movements so you can get a better understanding of your digestive health.

When it comes to frequency, factors such as diet, age, activity levels and eating habits can all impact bowel movement. What’s considered normal for one person, may not be normal for another – some people pass one stool every day, while others may go every other day. Typically speaking, the average range of stools tends to be no more than three stools per day and no less than three stools per week. The key is to figure out what’s normal for you, so that you can identify when this changes.

It's a good idea to take note of any changes in your bowel habits, colour and texture. If you’re concerned about any of the above, don’t hesitate to speak to your GP.

3. Exercise has no impact on gut health

It’s no secret that exercise is beneficial for our mental and physical wellbeing. In fact, studies have shown that people who are more physically active tend to have healthier guts, which helps support good immune health and digestion.

Physical activity increases blood flow to the muscles in the digestive system, which massages our food along the digestive tract. It’s also thought that in some cases, exercise can help to increase ‘good’ bacteria in the gut.

When it comes to exercising, we understand that everyone is different. While some people prefer to do more cardiovascular-based activities such as swimming and cycling, others may feel more comfortable doing gentle exercises such as walking, yoga and Pilates – it’s whatever works for you.

4. Bloating is all down to diet

If you feel like your stomach grows twice in size after eating a big meal or certain foods, then you’re certainly not alone. Many people suffer with bloating from time to time and a big misconception is that it’s all down to the foods we eat. But there are actually many other contributing factors that can trigger bloating, including:

• Swallowing too much air when you eat

• Some foods and drinks such as certain vegetables and fizzy drinks

• Food intolerances such as lactose intolerance

Problems with your digestion can also play a big role in bloating, including things like constipation, IBS as well as conditions like irritable bowel syndrome (IBS) and coeliac disease. Some people notice bloating more around their period, too.

If you frequently experience bloating or are experiencing bloating for the first time, speak to your GP.

5. Gluten is harmful to the gut

Similarly to bloating, there’s an old wives tale that gluten is harmful to the gut. But let’s break it down.

Gluten is a dietary protein found in wheat, barley and rye which is present in foods such as pasta, pizza bases, bread, cakes and some breakfast cereals. For some people, eating these foods can cause an adverse reaction or digestive difficulties shortly after eating them such as stomach pain, diarrhoea, bloating and constipation. These can be linked to conditions like coeliac disease (an autoimmune condition where your immune system attacks your digestive tract), a wheat food allergy and a gluten sensitivity or intolerance.

It’s because of this that many believe gluten is harmful to the gut. However, many people without digestive disorders related to gluten can eat gluten day-in-day-out without experiencing any ill effects, meaning there’s no reason to restrict this from your diet without good reason.

With that being said, if you do think you may have coeliac disease or a gluten intolerance or sensitivity, speak to your GP.

6. Diarrhoea is only caused by infection

If you experience a bout of diarrhoea, most people put this down to bacterial and viral infections, food poisoning or medicinal side effects. When the reality is that it can be caused by a whole host of other things such as a stressful evening, feelings of anxiety to a bacterial or viral infection – all of which are linked to the gut. It can also happen more frequently during menstruation.

When diarrhoea strikes, it can increase your risk of dehydration which can leave you feeling tired and dizzy. Treating diarrhoea will help replenish the loss of essential water and nutrients, regulating and restoring your digestive balance back to normal.

7. The more fibre, the better

Dietary fibre is good for your digestive health as it helps you to absorb nutrients, support good bacteria, aid digestion, help prevent constipation and create a feeling of fullness, too.

Eating plenty of fibre is also associated with a lower risk of heart disease, stroke, type 2 diabetes and bowel cancer. But did you know that 90 percent of adults in the UK population don’t get enough fibre? It’s recommended that adults consume 30g of fibre a day as part of a healthy, balanced diet through the likes of wholemeal breads, wholegrain cereals, potatoes with the skin on, beans, pulses, fruits, vegetables, nuts, and seeds.

However, there can be too much of a good thing, especially if you increase your intake too quickly. Consuming too much soluble fibre can lead to loose stools, bloating and gas, which makes it particularly troubling for those with conditions such as IBS. If you’re trying to increase your intake, try doing this gradually to avoid these symptoms and allow your gut to adjust to the higher intake. Make sure you’re also drinking plenty of water as this helps waste pass through your digestive system.

8. Cutting out or eliminating foods is good for your gut

One of the biggest myths about the gut is that you need to restrict your diet in order to keep it healthy. Some people are led to believe that cutting out or eliminating certain foods is the answer, particularly if they feel it’s causing their gut woes.

However, unnecessarily cutting out whole food groups can lead to nutritional deficiencies as well as impacting your gut microbes. The microbiome thrives on a diverse diet of plant-based foods (experts recommend 30 or more a week), which refers to fruits, vegetables, legumes, nuts, seeds, spices, spices and wholegrains. However, restricting your diet can actually decrease the gut microbe diversity.

A diet free from the likes of gluten and dairy is unlikely to be desirable for most people, unless you have an allergy, medical condition or intolerance to it, like coeliac disease or lactose intolerance. 

The bottom line? It’s more about the benefits of what you include as opposed to what you exclude.
