Gut health has become one of social media’s favourite buzzwords. From chia seed water in the morning to adding sea moss gel to smoothies, these foods are credited with everything from better moods to more energy. However, scientists warn that the reality behind these viral foods is more complex.
While the gut microbiome does play a crucial role in overall well-being, many of these so-called “gut-healing” foods have limited scientific backing. For most healthy people, obsessing over gut health may be unnecessary.
What is the Gut Microbiome?
The gut microbiome refers to the trillions of bacteria, viruses, and fungi that live in the digestive tract. According to BBC science broadcaster Caroline Steel, the microbiome plays an essential role in everything from energy extraction to immune defense. It also affects mental health, with research linking it to lower anxiety and better mood.
Steel emphasizes that a healthy gut microbiome is unique to each person, much like a fingerprint. It’s associated with better blood sugar regulation, immune function, and the overall health of the digestive system.
Do Viral Gut Foods Live Up to the Hype?
Many of the trending gut health foods, like chia seed water and bone broth, contain a “small seed of truth” but are often overstated as miracle solutions. Experts like microbiologist Alan Walker and gut health scientist Dr. Megan Rossi say that while these foods may offer some benefits, they are not the cure-alls they are often made out to be.
Chia Seed Water: A Source of Fiber, but Not a Miracle
Chia seeds are high in fiber, which can feed beneficial gut bacteria and aid bowel regularity. However, no single fiber source can fix gut health on its own. As Dr. Rossi explains, the diversity of fiber sources matters more than any one ingredient. Drinking chia seed water won’t hurt, but it won’t dramatically improve your gut health either.
Olive Oil Shots: Limited Impact on the Microbiome
Olive oil is praised for its anti-inflammatory benefits and heart-healthy properties. While it may help with constipation, there’s little evidence that taking it as a concentrated “shot” boosts the microbiome specifically. According to Walker, there’s no meaningful difference between drinking olive oil straight and adding it to food.
Sea Moss Gel: Claims with Little Scientific Support
Sea moss gel, a type of seaweed, is often marketed for its fiber and nutrients. However, Dr. Rossi points out that there is little scientific evidence to support its effectiveness for improving gut health. In fact, she cautions against taking large doses, especially for those with inflammatory bowel disease. Sea moss can also contain heavy metals and iodine, which may cause health issues if consumed excessively.

Bone Broth: Not the Gut Miracle It’s Made Out to Be
Bone broth is often touted as a nutrient-dense food with healing properties for the gut. However, Walker explains that most of the nutrients in bone broth are absorbed in the small intestine, not the large intestine where the majority of gut microbes live. As a result, bone broth may have minimal impact on gut health. Dr. Rossi adds that bone broth can have negative effects on cholesterol if the fat isn’t skimmed off properly.
Kombucha: Benefits Vary Based on Quality
Kombucha, a fermented tea, contains natural acids and antioxidants created during fermentation, which may provide health benefits. However, not all kombucha is the same. Dr. Rossi advises choosing kombucha with visible floaters, as this indicates a live culture. It’s also important to avoid sugar-free varieties that contain artificial sweeteners.
Gut Health: When to Seek Medical Advice
While gut health has become a hot topic, it’s essential to remember that most people don’t need drastic dietary changes. If you experience persistent symptoms like constipation, diarrhea, excessive gas, or abdominal pain, it’s important to seek medical advice rather than relying on popular trends.
Caroline Steel warns against turning to extreme elimination diets in an attempt to “heal” the gut. For most people, a balanced diet with more plant-based foods, increased fiber, and fewer ultra-processed items is the best approach.
Conclusion: Keeping Your Gut Happy
Rather than chasing trends, focus on easy, sustainable changes to improve your gut health. Eating more plant-based foods, increasing your fiber intake, and cutting back on processed foods can support a healthy microbiome without the need for trendy foods.
