Well, maybe stopping it would be extreme — calcium is critical to bone density, and maintaining it is a challenge for the elderly. However, something that often comes along with milk, at least in the U.S. is vitamin D. You need a certain amount of vitamin D in order to absorb the calcium, and seniors are often deficient in the vitamin. However, taking vitamin D supplements really may not be the solution. Although the study is, again, a very small sampling, the latest research out of Switzerland actually indicates that taking vitamin D supplements can increase the rate of falls amongst seniors. So, drink your milk, but be cautious before taking vitamin D supplements.
