I recently read this compelling tale of how a mother discovered a link between milk allergy and attention deficit hyperactivity disorder (ADHD) in her daughter.

Milk is often touted as the perfect food. It does a body good, right? Apparently, it does a lot of bodies bad. Milk allergy is implicated in all sorts of odd disorders, and it often goes unnoticed for years or even lifetimes since milk is so common in our society. Other food allergies are also implicated in everything from behavioral disorders to arthritis. If you think about it, we humans are the only mammals that continue to drink milk well after childhood.

Here's another little-known fact about milk: It's often marketed as a good way to prevent osteoporosis because of its relatively high calcium content; however, the animal protein in milk also intensifies the urinary excretion of calcium–and several scientific studies have concluded that the consumption of this animal protein increases the risk of bone fractures.
