In a recent study at Wake Forest University School
of Medicine, people who had high levels of vitamin D in their blood
were significantly stronger during a grip-strength test than those with
lower amounts. "Vitamin D deficiencies have been associated with
muscle weakness," says Denise Houston, the study's author. "It may be
because the nutrient regulates calcium-which is crucial for protein
synthesis-and a hormone that helps build muscle." For maximum
strengthening and added protection from many diseases, including
several forms of cancer, you need at least 400 international units (IU)
of vitamin D a day. One cup of fortified yogurt or milk will give you
100 IU; a serving of fortified cereal such as Total, the whole shebang.
Stronger bones and muscles? We'll drink (milk) to that.
