The Gut Health Trend: What the Experts Say About Healing Your Gut Naturally

#GutHealth

TikTok explodes with content under the #guthealth hashtag.

In practical terms, this is TikTokers — sometimes professionals and sometimes not — unveiling their gut health secrets and journeys, offering tips on how to “reset” or “heal” your gut, do “gut cleanses”, and warning about what can be toxic to your gut’s wellbeing. More often than not, these videos link gut health issues with hormonal issues; many users’ tips are, for instance, addressed towards solving acne problems, bloating and constipation, and cortisol imbalance.

This advice is often quite simple — it does not involve taking medication or following complex dietary plans. When it comes from experts, especially gastroenterologists, it mostly focuses on cutting back on ultra-processed foods and on including more fibre, prebiotics — like garlic, onion, and asparagus — and probiotic-rich foods like yoghurt, dahi, and kafir, and increasing your water intake, according to Doctor Sethi.

On the other hand, among the many professionally reviewed TikToks, some unverified information is gaining popularity. One TikToker claims that healing your gut should start with a gut-healing morning routine that includes hydration before coffee — popular drinks in the gut health TikTok community are celery juice and kombucha — eating a balanced breakfast, and practising mindfulness and stress-relief practices like meditation and yoga. Although this is not bad advice, it is important to always view social media’s unprofessional guidance with a critical lens, as it often fails to address the more serious underlying issues of gut health and might oversimplify the matter.

Let’s Talk About Guts

Research led by the Institute of Nutritional Medicine at the University of Hohenheim shows that the gastrointestinal tract plays an essential role in our overall health, far beyond simply processing food and absorbing nutrients and fluids. Research, including animal and human studies, has shown that our gut works closely with bacteria that help break down food and aid digestion. The gut also plays a role in regulating key functions of our immune system and the lining of our intestines, both of which are crucial for maintaining good health.

Additionally, the gut communicates with the brain through nerves and hormones, sending signals about how much energy we are taking in and even influencing our mood and sense of well-being. Recent studies in germ-free mice have revealed that the collection of bacteria in the gut, known as the gut microbiota, can affect not only how the digestive system works but also how the brain develops, impacting behaviour and brain chemistry.

To truly understand gut health, it helps to know that the gut barrier is composed of several layers and systems: the lining of our intestines, the gut immune system, the network of nerves that control gut movement, supporting tissues, muscles, and a steady blood supply. This barrier does more than just defend our bodies from potential threats inside our digestive tract. It also helps us absorb the nutrients we need, fosters a healthy relationship with beneficial bacteria, and allows our immune system to tolerate harmless substances.

When the gut barrier is healthy and intact, it keeps our digestive system working smoothly. But if this barrier is disrupted, it can be an early sign not only of digestive diseases but also of conditions that affect other parts of the body.

What Does a Healthy Gut Look Like?

A healthy gut is reflected in how well our body absorbs nutrients, water, and minerals from the food we eat. It shows in having regular, comfortable bowel movements without symptoms such as nausea, vomiting, constipation, or bloating. When the gut is functioning properly, there are no ongoing issues such as acid-related diseases, inflammation, enzyme deficiencies, or food intolerances. There is also no presence of chronic inflammatory conditions like inflammatory bowel disease or coeliac disease, and no signs of gastrointestinal cancers.

The balance and health of the microbes living in our gut are also important. A healthy gut does not have excessive growth of harmful bacteria, and the community of good bacteria is strong and active, and this balance ultimately protects us from infections.

The gut’s natural barrier also works effectively, producing the right amount of mucus and preventing harmful bacteria from entering our bodies. The gut immune system is balanced, with normal numbers and activity of immune cells, and the body shows tolerance to harmless substances without allergies or excessive immune reactions.

When all these aspects are in harmony, a person enjoys a good quality of life, feels well-being, and experiences a positive gut feeling. The gut’s own nervous system and serotonin production are balanced, supporting both digestive health and emotional balance.

How to Take Care of Your Gut Health

Harvard Medical School lists simple, easily achievable steps we can take to support our gut health.

Increasing your fibre intake is essential. Fibre feeds the friendly bacteria living in your gut, helping them thrive and keeping your digestive system in good shape. A diet rich in fibre is linked to a more diverse community of gut microbes and a lower risk of common digestive problems such as constipation. These include beans, whole grains, avocados, sweet potatoes, Brussels sprouts, tofu, berries, leafy greens, and a variety of nuts and seeds. Aim for twenty-one to thirty-eight grams of fibre each day.

Drinking enough water is another key to gut health. Water helps your body absorb nutrients, keeps your core temperature steady, and supports the production of protective mucus in your digestive tract. Being well hydrated also helps prevent constipation and keeps the gut bacteria environment healthy. For most people, four to six cups of water a day is a good goal.
