U of M expert available to discuss low Vitamin D in diets of adults
In many parts of the country, cooler weather has started moving in.
A steady drop in temperatures normally hustles people indoors. Unfortunately hibernating during the winter months can cause a decline in vitamin D, the ‘sunshine’ vitamin that is crucial to bone health.
Just how bad has vitamin D insufficiency gotten and what can people do to get more of the “sunshine vitamin” during the winter months? A University of Minnesota expert who has studied the effects of vitamin D insufficiency and can offer tips to keep you healthy this winter is:
Lisa Harnack, professor of epidemiology, School of Public Health and director of the Nutrition Coordinating Center
Vitamin D is essential for the development and maintenance of healthy bones. Unfortunately many Americans (Minnesotans included) don’t get enough vitamin D in their diets to meet recommended intake levels. In fact, Harnack’s latest research – recently published by the Journal of the American Dietetic Association – shows vitamin D in the diet has been heading in the wrong direction.

“Over the past 25 years vitamin D in adult diets has been on the decline, making a bad situation worse”, said Harnack. “Both men and women have shown a steady decrease in their vitamin D intake.”
Harnack says that this winter, residents across Minnesota should aim to include vitamin D rich foods in their diets on a daily basis.
What are some good food sources of vitamin D?
• All types of dairy milk (e.g. 2%, skim, etc.) are fortified with vitamin D. Some brands of soy, rice and other non-dairy milks are fortified with vitamin D while others are not. Read the lable to choose a product that is fortified.
• Some brands of cereal, yogurt, margarine, and orange juice are fortified with Vitamin D. Read the nutrition facts panel to find fortified brands.
• Some foods like fish and mushrooms naturally contain vitamin D. The list of foods that are naturally good sources of vitamin D is short. As a result, most people need to rely on food products fortified with vitamin D to get sufficient vitamin D in their daily diets.
