The conversation around immunity has evolved from reliance on vitamin C and supplements to a focus on gut health, which is seen as the body's immune headquarters. Prachi Mandholia, a Clinical Nutritionist based in Mumbai, explains that nearly 70% of the immune system is associated with gut health, specifically through gut-associated lymphatic tissue (GALT). The gut microbiome, consisting of trillions of microorganisms, influences various bodily functions, including digestion and immunity. With rising awareness post-pandemic, many are now prioritizing gut health through the consumption of probiotics found in fermented foods like curd, kimchi, and kombucha. Additionally, prebiotic foods, such as bananas and garlic, play a vital role in supporting these beneficial bacteria. Emerging research is also linking gut health to mental and skin health through the gut-brain and gut-skin axes. To enhance gut health, a 'food-first microbiome' approach is suggested, emphasizing diverse, local, and seasonal foods while reducing processed sugars and maintaining a balanced lifestyle.
