Vitamin D Deficiency Affects Nearly 70 Percent of Americans
Nearly 70 percent of adults and children in the United States are deficient in vitamin D. Long known for its contribution to strong bones, recent research suggests that Vitamin D may play critical roles in cancer prevention, heart and blood vessel health, and pregnancy.
In most cases, Vitamin D deficiency stems from to lack of sun exposure and not getting enough of the vitamin in the diet. Sun exposure is the primary way that the body manufactures Vitamin D – but it also increases your risk of skin cancers. You can increase your Vitamin D level by making small changes in your diet.
Good food sources of vitamin D include:
- Vitamin-D fortified milk or orange juice
- Vitamin-D fortified cereal
- Oily fish such as tuna, salmon, swordfish, and mackerel
- Egg yolks
- Beef liver
- Vitamin-D fortified yogurt
