Alkaline Diet

The recommendation to eat only alkaline foods and avoid acidic ones is not grounded in nutrition or biochemistry. Food pH does not determine whether a food is healthy or harmful; its nutrients do. Alkaline water and alkaline-classified foods do not raise blood pH in healthy individuals; the kidneys excrete the excess. The alkaline diet's core premise collapses when examining how pH actually varies across body compartments. Pursuing an alkaline diet can disrupt the stomach, colon, and urinary tract — compartments that must remain acidic to function and protect the body. Avoiding acidic foods, taken to its logical conclusion, means avoiding the biochemical building blocks of life itself.
