I hear about “essential nutrients” frequently, what are they?
R/ Essential nutrients are essential for the maintenance of basic daily functions for health and life itself. These functions are carried out in every cell and every organ of the body, every minute of every day, from birth to death. An essential nutrient is a substance that the body must have to function, but which it cannot produce on its own, therefore, the nutrient must be obtained from external sources, that is, from food.
There are 13 vitamins (which by definition are essential), 15 essential minerals or electrolytes, nine essential amino acids, and two essential fatty acids.
