Gut health has officially gone viral. Scroll TikTok or Instagram for five minutes and you’ll be told to drink chia seed water at sunrise, down a shot of olive oil, add sea moss gel to everything, or sip bone broth like medicine — all promising to “heal” your gut, boost mood, fix digestion, and unlock endless energy.
But do these trending gut health foods actually live up to the hype? Or are they another case of wellness marketing running ahead of science?
Experts say the truth is far more nuanced — and for most people, far less dramatic.
What Is the Gut Microbiome (And Why Everyone Is Talking About It)?
The gut isn’t just your stomach. It’s your entire digestive system, stretching from your mouth to your anus. Inside it lives the gut microbiome — trillions of bacteria, viruses, and fungi that influence digestion, immunity, metabolism, and even mental health.
According to BBC science broadcaster Caroline Steel, your gut microbiome is more unique than your fingerprint. A balanced microbiome has been linked to:
- Better energy extraction from food
- Stable blood sugar levels
- Stronger immune defenses
- Lower anxiety and improved mood
That connection explains why gut health has become a social media obsession. But uniqueness is also the key problem: what works for one gut won’t work for everyone.
Do Viral Gut Health Foods Actually Improve Your Microbiome?
Microbiologist Alan Walker and gut health scientist Dr Megan Rossi agree that many viral foods contain a small grain of truth — but are wildly oversold as miracle cures.
Here’s what the science says about the biggest gut health trends.
Chia Seed Water
Verdict: Helpful, but not magical
Chia seeds are rich in fiber, which can support digestion and feed beneficial gut bacteria. They may help with bowel regularity — but that’s where the benefits stop.
Walker explains that no single fiber source feeds all gut microbes. Different bacteria thrive on different fibers, meaning diversity matters far more than one trendy drink.
Bottom line: Drinking chia seed water won’t hurt, but on its own, it won’t “heal” your gut.
Olive Oil Shots
Verdict: Same benefits, unnecessary format
Extra virgin olive oil is well known for its anti-inflammatory and heart-health benefits. It can also help relieve constipation.
But taking it as a concentrated “shot”? There’s no evidence that doing so improves the gut microbiome more than simply adding it to meals.
“There’s no meaningful difference between drinking it straight and eating it with food,” Walker says.

Sea Moss Gel
Verdict: Popular, poorly proven, potentially risky
Sea moss gel (a type of seaweed) is hyped for its fiber, minerals, and vitamins. But Dr Rossi says there’s very little scientific evidence supporting claims that it improves digestion or gut bacteria.
More concerning: seaweeds can contain high levels of iodine and heavy metals. Excess intake may cause health issues — especially for people with inflammatory bowel disease.
This is one trend experts urge caution with.
Bone Broth
Verdict: Comforting, nutritious — not a microbiome fix
Bone broth is made by simmering animal bones for hours to extract minerals and proteins. While nutrient-dense and soothing, it doesn’t significantly feed gut bacteria.
Most of its nutrients are absorbed in the small intestine, while the majority of gut microbes live in the large intestine — meaning very little reaches them.
There’s also a downside: if saturated fat isn’t skimmed off, it may negatively affect cholesterol levels.
Kombucha
Verdict: One of the better options — if it’s real
Fermented foods can support gut health, and Dr Rossi says she’s a fan of traditional kombucha. Fermentation produces organic acids and antioxidant compounds linked to health benefits.
But not all kombucha is equal. Experts recommend:
- Look for natural “floaters” (living cultures)
- Avoid brands with added vinegar
- Skip sugar-free versions with artificial sweeteners
Authentic fermentation matters more than branding.
Signs Your Gut Might Actually Need Help
According to Caroline Steel, genuine gut issues may include:
- Persistent constipation or diarrhea
- Excessive gas
- Ongoing abdominal pain
In these cases, medical advice matters more than diet trends. Extreme elimination diets or cutting out foods like bread rarely “heal” underlying problems.
“If you’ve got a problem with your gut, cutting out bread isn’t going to fix it,” she says.
The Truth About “Healing” Your Gut
Here’s the reality most influencers won’t say: most people don’t need to heal their gut at all.
If your gut is already healthy, no viral drink or supplement is going to transform it. Obsessing over gut fixes can do more harm than good.
Instead, experts consistently recommend simple, evidence-backed habits:
- Eat a wide variety of plant foods
- Increase fiber intake
- Cut back on ultra-processed foods
- Focus on consistency, not quick fixes
Final Takeaway
Viral gut health foods aren’t scams — but they’re not miracles either. The microbiome thrives on diversity, balance, and long-term habits, not shortcuts.
If there’s one lesson from science, it’s this: your gut doesn’t need trends — it needs variety and patience.
And sometimes, the best gut health advice is also the least viral.
