In today’s fast-paced lifestyle, many people rely heavily on protein powders, vitamin gummies, and so-called “smart” supplements to stay mentally and physically fit. But neurologists from the group The Brain Docs say the real key to maintaining your mental health could already be sitting in your fridge or kitchen shelf.
In a recent viral Instagram post, they shared their take on fibre, calling it “one of the most overlooked tools for brain health.” They believe that eating a diet rich in fibre from everyday foods like fruits, vegetables, and whole grains can significantly improve one’s mood, focus, and overall mental well-being.
The link between your gut and brain isn’t just a trending topic—it’s backed by decades of scientific research. The gut-brain axis is a two-way communication system between your digestive tract and your central nervous system. When your gut is healthy, your brain tends to be healthier too.
As The Brain Docs explain, fibre feeds the “gut-brain axis,” strengthening this critical system and enhancing how we process emotions, manage stress, and stay mentally resilient.
A scientific review published on PubMed examined 18 studies focused on diet and mental health. The findings were eye-opening:
For every 5 grams of fibre added to the diet, adults experienced a 5% lower risk of depression.
These numbers underline just how important dietary fibre can be—not just for digestion, but for emotional and cognitive health too.
The best part? You don’t need to break the bank or chase exotic ingredients. Here are some fibre-rich, accessible foods to include in your daily meals:
Broccoli
Asparagus
Carrots
Bananas
Apples
Berries
Garlic
Onions
Oats
Lentils
Barley
Seeds (chia, flax, etc.)
These foods promote the growth of good gut bacteria, which directly correlates with better mental clarity, mood balance, and even sleep.
A report by The Mirror found that vegetables and soluble fibres had the strongest link to improved mental health. While cereal and fruit fibres were slightly less impactful, they still contributed to lowering the risk of depression.
“This isn’t just another trend, it’s a shift in how we think about food and mental well-being,” say experts.
According to health experts, adults should aim to consume 25 to 30 grams of fibre daily—and don’t forget to stay hydrated, as fibre works best with adequate water intake.
You can meet your daily fibre needs with these simple changes:
Breakfast: Start with yogurt and a banana
Lunch: Add a fibre-rich lentil salad
Dinner: Try a broccoli and barley stir-fry
These small tweaks can go a long way toward improving your gut and, in turn, your mind.
In a world dominated by quick fixes and supplement fads, neurologists are reminding us of the power of whole foods. The Brain Docs have brought attention to an often-ignored nutrient—fibre—which research suggests may significantly reduce the risk of depression.
With a strong link between gut health and brain function, fibre feeds the gut-brain axis, helping to improve emotional regulation and mental resilience.
Scientific reviews confirm that adding as little as 5 grams of fibre daily can bring measurable benefits. Best of all, you don’t need expensive or exotic ingredients.
Everyday items like oats, apples, lentils, and broccoli are more than enough to support your brain. By making simple, consistent changes to your meals, you can nurture both your gut and mind.
So next time you're at the grocery store, skip the supplement aisle and stock up on nature’s brain boosters instead—your mental health might thank you for it.
