Drinking milk is essential to building strong bones, right? Not necessarily. Milk does not make you less prone to bone fractures. Also, the nutrients in milk can be found from other sources in higher amounts, and one in four Americans can't even digest dairy. The idea that milk is necessary for good health is a myth that has been perpetuated by the U.S. federal government in order to sustain the dairy industry. During WWI, farmers focused exclusively on dairy to send milk to malnourished soldiers. Canned powdered milk is good for providing nutrients in cold, harsh conditions in which vegetables can't grow. This created a huge milk surplus, and the easiest way to consume it was to convince American citizens to drink more.
