Vitamin D is important for strong bones, good health

Vitamin D.jpgVitamin D is often called the “sunshine vitamin” because our bodies can make vitamin D when sunlight contacts the skin. During our dark winter months, many Alaskans are getting very little (if any) vitamin D from sunlight exposure, so we need to think about getting the vitamin through foods and supplements. Vitamin D is important for strong bones and may contribute to overall good health.

“Eating healthy foods is always the best option”, says Diane Peck, Registered Dietitian Nutritionist with the Alaska Section of Chronic Disease Prevention and Health Promotion. “Healthy foods provide so many more nutrients and other benefits that aren’t found in supplements. But for many people in Alaska, taking a vitamin D supplement along with a healthy diet may be appropriate.”

Lucky for us, some of the foods with the most vitamin D are found in Alaska. Traditional diets protected Alaska Native people during the long, dark winter. Salmon — fresh, canned or smoked — is an excellent source of vitamin D. Marine mammals, fish oil and seal oil contain large amounts of vitamin D. Oysters, shrimp, halibut, flounder, and rock fish are good sources, too. 

Other foods that contain vitamin D include tuna fish, cod liver oil, egg yolks, and some mushrooms. Vitamin D has also been added to many foods. Look for the words “vitamin D fortified” on packages of milk, soymilk, yogurt, orange juice, oatmeal, and ready-to-eat cereals. For a list of foods and their vitamin D content, see the U.S. Dietary Guidelines.
 
The amount of vitamin D needed varies throughout your lifespan. You can learn more about the Recommended Dietary Allowance (RDA) for vitamin D at https://ods.od.nih.gov/factsheets/VitaminD-Consumer/. Besides living in a place without much sunlight, other factors may affect vitamin D levels:
 
• People with darker skin don’t produce vitamin D as quickly as people with lighter skin.
• Older adults may not produce vitamin D as well as younger people.
• Breastfeeding is the best choice for the health of infants, but breast milk can be low in vitamin D.
 
If you think you’re not getting enough vitamin D, talk with your health care provider. It is important to note that taking too much vitamin D can have negative effects and may interact with other medications you’re taking.
 
For more information about vitamin D, see this Alaska Section of Epidemiology website and this State of Alaska educational resource.
