Calcium added to soy milk is good for bones. But it tends to settle and then can be quite tough to redistribute into the milk. According to a study from Creighton University in Nebraska, fortified soy milks may deliver only 25% to 79% of the promised calcium, depending on the type used and the way it’s added. In cow’s milk, calcium is naturally suspended throughout the liquid.
What to do: Shake that soy milk each time. And consume calcium from a variety of sources to get the full amount you need daily: 1,000 to 1,200mg.
