Immunity isn’t just a buzzword, it’s the foundation of how our bodies protect, prevent, and heal. In this #NuaTalks video, Nua sits down with nutritionist and lifestyle educator Karishma Chawla to unpack one of the most important yet misunderstood aspects of health: why immunity begins in the gut.
With expertise in weight loss, gut health, and hormone balance, Karishma explains how these areas are interconnected. She reminds us that immunity isn’t about invincibility, but about balance. Too much activity can harm, too little leaves us unprotected. And that balance, she says, starts in the gut.
It’s striking to learn that 70–80% of our immune system resides in the gut, making it a vital ecosystem influenced by every bite, habit, and stressor. Poor diets, irregular routines, and environmental toxins can compromise gut health, triggering inflammation and weakening immunity.
But the message is hopeful: nurture the gut, and you strengthen not only digestion but also hormones, metabolism, brain health, and resilience. With 90% of our body made up of bacterial cells, some 35,000 species, the gut microbiome is an organ in itself, vital to growth and protection.
Karishma’s message is clear: strong immunity starts with mindful routines and gut care. When we support the gut, it supports us in return.
