                                The human body absorbs an impressive 95% of macronutrients from the small intestine. A fundamental concept in nutrition is understanding that these absorbed nutrients follow one of two distinct routes, which determine their initial destination and processing: which nutrients go into the portal blood after being absorbed and which go into the lymphatic system?. This critical divergence is based primarily on the nutrient's solubility.
