Growing evidence indicates that the gut is pivotal in human health and the progression of many diseases, including inflammatory conditions, obesity, type 2 diabetes, cardiovascular diseases, mental health issues, and cancer. It is the principal organ tasked with digesting the food we consume and absorbing nutrients. The gut underpins all bodily functions, from energy production and hormonal balance to mental well-being, skin condition, and the elimination of toxins and waste. It is estimated that roughly 70% of the immune system resides within the gut.
