4 Simple Rules for a Healthy Gut

Reported by Vogue.

Your gut is running the show — and most of us have no idea. According to Vogue, recent advances in gene sequencing have given scientists a dramatically clearer picture of the bacterial ecosystem living inside us, and what they've found is hard to ignore. French scientist and pharmacist-biologist André Burckel explains that the microbiota can "send messages to the brain, with an impact on neurotransmitters which then act on mood." Meaning your digestive tract isn't just processing lunch — it's influencing how you sleep, how you feel, and how well your immune system fights back.

Feed It Like You Mean It

Burckel's framework, outlined in The Burckel Diet, for Microbiota Health, zeroes in on five dietary non-negotiables: resistant starches (beans, bananas, wheat) that feed good bacteria; beta-glucans from oats and barley that simultaneously boost beneficial microbes and lower cholesterol; fructans from asparagus, chicory, and melon to keep things balanced; fiber from kale, figs, and almonds that fuels short-chain fatty acid production for brain and metabolic health; and polyphenols from dates, tea, cocoa, and spices that act as natural prebiotics. Amy Shapiro, RD, founder of Real Nutrition, keeps it even simpler: eat the Mediterranean diet, eat varied, and remember that "diversity matters." Raw or lightly cooked food also deserves a spot in your rotation — French chef Marie-Sophie L., author of Raw Food, notes that heat above 42°C (107°F) destroys key nutrients and fibers. Her daily staples: nuts, chia and hemp seeds, vegetable juices, and apples, which support liver health through their fiber, antioxidants, and malic acid.

On the probiotic front, fermented foods — kimchi, kefir, yogurt, pickles — are your most accessible entry point. Nutritionist Cristina Barrous calls them "key for providing special probiotics to the diet," and recent research backs that up, linking fermented food consumption to reduced risk of diabetes, cardiovascular disease, obesity, and even age-related cognitive decline. For a more targeted approach, Dr. Valérie Leduc, a specialist in antiaging medicine, advocates for microbiota DNA analysis to guide personalized probiotic prescriptions — a next-level move worth exploring if you've been dealing with persistent issues.

But no supplement or superfood will compensate for a life lived on fumes. Shapiro is direct: "Gut health is a full-lifestyle conversation" — one that requires adequate sleep, consistent movement, and actual stress management. The warning signs of a struggling microbiome go beyond bloating and bathroom issues. Skin flare-ups, brain fog, relentless sugar cravings, and a compromised immune system are all flags worth taking seriously. The upside, per Shapiro: "The gut is responsive to change." It just requires a real commitment, not a three-day cleanse.

Your mood, your skin, your energy — it all starts in your gut, which means the most radical thing you can do for your overall health is also the most unglamorous: eat more plants, stress less, and sleep like it's your job.
