What is a nutrient or qualifies as one?
The Expert Report defines nutrients as traditional vitamins, minerals, and essential fatty acids for which recommended intakes have been established. The definition also includes other components that include phytonutrients or bioactive substances present in foods for which a physical or physiological effect has been scientifically documented, or for which a substantial body of evidence exists for a plausible mechanism, but for which a recommended intake and function have not been definitively established.
