Nutrition scientists began to refine this hypothesis in the early 20th century, emphasizing the role of negatively charged particles and positively charged particles in food. Diets high in chloride, phosphate and sulfate (all of which are anions) were presumed to be acid forming, while diets high in potassium, calcium and magnesium (all of ...
As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels. For precise details about vitamins and mineral contents, the USDA source can be used. [1] To use the tables, click on "show" or "hide" at the far right for each food category.

Only two essential fatty acids are known to be essential for humans: alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid).
