How to enhance internal microbial balance through strategic dietary choices

The equilibrium of human health is fundamentally linked to a complex system of microorganisms residing within the digestive tract.

These microbes govern vital functions ranging from metabolism and immunity to concentration and mood regulation.

To understand how specific dietary choices shape this ecosystem, HT Lifestyle consulted Dr Debojyoti Dhar, a molecular biology expert and cofounder of BugSpeaks.

Fibre-rich vegetables

Dr Dhar explained that what you eat shapes your gut microbiome, a complex ecosystem of microorganisms.

He emphasised that "The way to improve gut health is by consuming specific foods instead of simply eating foods from larger categories of foods called ‘food groups,’" specifically recommending:

• Leafy greens: Good sources of insoluble fibre, providing substrate for microbiota diversity. Examples include spinach, fenugreek, mustard greens, and kale.
• Cruciferous vegetables: These contain compounds aiding detoxification and beneficial bacteria. Key examples are broccoli, cauliflower, cabbage, and Brussels sprouts.

Daily consumption is vital because "Eating vegetables will promote short-chain fatty acid production in the colon, which strengthens the colonic barrier and reduces inflammation."

Fermented food

The second category involves fermented items such as homemade curd. Dr Dhar noted that "Fermented foods contain live cultures that directly improve digestion and assist in nutrient breakdown," helping to re-establish microbial balance after illness.

Prebiotic-rich foods

Finally, the biologist suggests prebiotics as an energy source for bacteria. Sources like garlic, onion, leek, banana, oat, barley, chickpea, and lentil ensure that "beneficial bacteria grow and multiply,' and, in the process, they overtake or suppress the growth of harmful bacteria."
