A recent report from Turkey shows that women who wear veils have lower blood levels of vitamin D and therefore are at increased risk for suffering osteoporosis.

Vitamin D is found in egg yolks, liver and salt-water fish oils from sardines, herring and salmon. The vast majority of people on earth do not eat enough of these foods to meet their requirements for vitamin D, so they have to depend on sunlight. You get enough vitamin D to meet your requirements by exposing a few inches of skin to sunlight for less than one half hour a day. Veiled women in Turkey rarely expose any part of their bodies to sunlight, so they have low blood levels of vitamin D that increase their risk for osteoporosis. Fortified milk is not a good source of vitamin D because the calcium in milk uses up vitamin D to increase a person's need for that vitamin.
