This isn’t news in some health-conscious circles, but it’s wonderful to see it addressed so prominently in the New York Times. This article challenges the idea, long touted by the dairy industry, that milk is beneficial in combating osteoporosis. It goes even further and suggests that maybe it is part of the problem.
The science of osteoporosis and its resultant fractures has long been plagued by some vexing observations. Why, for example, are osteoporotic fractures relatively rare in Asian countries like Japan, where people live as long or longer than Americans and consume almost no calcium-rich dairy products? Why, in Western countries that consume the most dairy foods, are rates of osteoporotic fractures among the highest in the world? And why has no consistent link been found between the amount of calcium people consume and protection against osteoporosis?
An alternative theory of bone health may — or may not — explain these apparent contradictions. It is the theory of low-acid eating, a diet laden with fruits and vegetables but relatively low in acid-producing protein and moderate in cereal grains. Its proponents suggest that this menu plan could lead to stronger bones than the typical American diet rich in dairy products and animal protein, often enhanced by calcium supplements.
