Gut health has become one of the most talked-about wellness topics online. From influencers promoting olive oil shots on an empty stomach to claims that bone broth can "heal" the gut, social media is filled with quick-fix solutions promising better digestion, more energy and improved wellbeing. But according to gut health experts, the science behind many of these viral trends is far less dramatic than social media suggests.
Why the Gut Microbiome Matters
The gut microbiome refers to the trillions of microorganisms including bacteria, viruses and fungi that live throughout the digestive tract. Research suggests these microbes help digest food, regulate blood sugar, support the immune system and may even influence mental health.
Scientists have also found links between a healthy gut microbiome and lower levels of anxiety, improved mood and better metabolic health. However, experts caution that gut health is highly individual, making universal dietary solutions unlikely.
Chia Seed Water: Helpful But Not a Miracle Drink
Chia seed water has become a popular morning ritual among wellness influencers. Chia seeds are rich in fibre, which can help support bowel regularity and provide nourishment for beneficial gut bacteria. However, experts note that relying on a single source of fibre is unlikely to transform gut health. Different microbes thrive on different types of fibre, making dietary diversity far more important than any one ingredient.
For most people, chia seed water is safe to consume but it should be viewed as one component of a balanced diet rather than a standalone gut-health solution.
Olive Oil Shots: Better in Your Meals
Extra virgin olive oil is well known for its heart-health benefits and anti-inflammatory properties. Some evidence also suggests it may help relieve constipation in certain individuals. However, there is currently little evidence that taking olive oil as a concentrated shot provides additional benefits for the gut microbiome compared with simply using it in cooking or as a dressing.
Experts say the nutritional value remains largely the same whether it is consumed straight or incorporated into meals.
Sea Moss Gel: Trending Faster Than the Science
Sea moss gel, a supplement derived from seaweed, has gained popularity for its fibre content and naturally occurring vitamins and minerals.
Despite its growing popularity, scientific evidence supporting its use specifically for gut health remains limited. Experts also warn that excessive consumption may expose people to high levels of iodine and potentially harmful heavy metals, both of which can pose health risks when consumed in large amounts.
People with digestive conditions such as inflammatory bowel disease may want to exercise particular caution.
Bone Broth: Nutritious But Not a Gut-Healing Elixir
Bone broth is often promoted as a gut-repairing superfood. Made by simmering animal bones with vegetables, herbs and acidic ingredients for extended periods, it contains protein, collagen and minerals. While bone broth can be nutritious and comforting, experts point out that most of its nutrients are absorbed in the small intestine. Since the majority of gut microbes reside in the large intestine, there is limited evidence that bone broth directly improves the microbiome.
Nutrition experts also note that bone broth can contain significant amounts of saturated fat if excess fat is not removed during preparation, which may not be ideal for people managing cholesterol levels.
Kombucha May Offer Some Benefits
Among the trending gut-health foods, kombucha appears to have stronger scientific support. The fermented tea contains naturally occurring acids and plant compounds produced during fermentation, some of which have been linked to potential health benefits.
However, not all kombucha products are created equal. Experts recommend choosing traditionally fermented varieties and checking labels carefully, as some commercial products contain added sweeteners or ingredients that may reduce their potential benefits.
Do You Actually Need to 'Heal' Your Gut?
One of the biggest misconceptions surrounding gut health is that everyone needs to actively repair or detoxify their digestive system.
Experts say that most healthy individuals do not require special gut-healing protocols. Persistent symptoms such as ongoing abdominal pain, chronic constipation, diarrhoea or excessive bloating should be evaluated by a healthcare professional rather than treated with restrictive diets or social media remedies.
The Gut Health Advice Backed by Science
While researchers continue to learn more about the microbiome, one recommendation remains consistent, i.e., focus on overall dietary quality rather than chasing viral trends. Supporting gut health is often less about expensive supplements and more about sustainable habits, including:
- Eating a wide variety of plant foods
- Increasing fibre intake
- Including fermented foods where appropriate
- Limiting ultra-processed foods
- Maintaining regular physical activity
- Prioritising adequate sleep
As interest in gut health continues to grow, experts say the simplest advice remains the most effective: nourish your microbiome with a diverse, balanced diet rather than relying on a single superfood to do all the work.
