Nutrition is a complex and sometimes confusing subject. The existing classification of nutrients into two groups, macro and micronutrients, does not do justice to the wide spectrum of nutritional foods available. In this opinion piece, we suggest a six-layered 6M hierarchal classification of nutrients that offers a comprehensive and complete understanding of nutrition. Mega, macro, meso, micro, micro-bio, and minimization of anti-nutrients make up the 6M list of nutrients.
