Milk, butter, eggs, fortified cereals, and seafood are all good food sources of vitamin D. As I’ve previously said, exposure to the sun is important because sunlight actually helps our body produce vitamin D. But we’re also told that exposure to the sun is largely responsible for skin aging, skin cancer, and the development of melanoma. Because of this, the authorities who urge us to limit our exposure to the sun are quite correct. But if a lack of sunlight is coupled with a poor dietary intake, vitamin D deficiency can develop. This sequence of events is common in lots of us older folks, but particularly in people who are institutionalized and also in the homebound elderly.
