Calcium in Soy Milk
Soy milk is a healthy alternative to cow's milk for people who are lactose intolerant and for vegetarians who don't eat dairy. If you drink soy milk, however, you should be aware that your body may not be getting as much calcium as the nutrition label leads you to believe.
A study has shown that the body does not absorb the calcium in calcium-fortified soy milk as well as it absorbs the calcium in cow's milk. Even if the labels on a soy milk carton and a regular milk carton claim the same amount of calcium, your body will absorb about 25% less calcium from the soy milk.
This isn't necessarily bad news; you can make some simple adjustments to get the amount of calcium you need. For example, you could simply drink more of the soy milk. Or you could include more calcium-rich foods in your diet, such as greens, broccoli, dried beans, and tofu.
