Getting adequate amounts of vitamin D can be difficult, which is why many individuals take supplements to help them improve the levels of this nutrient in their body. Recently, Consumer Reports published an article on a study which found that eating more cereal may be a good way for people to boost their vitamin D levels.

The study, which was published in the Journal of Food Sciences, examined more than 11,000 individuals from the U.S. and Canada and found that less than 2 percent of them got enough vitamin D from food sources. However vitamin D-fortified cereal may be able to help people get more of the nutrient.

"In the U.S., cereal - which is often fortified with vitamin D - also ranked among the top food sources. And in both countries, as the frequency of cereal consumption and breakfast consumption went up, so did overall vitamin D intake," according to the news source.

The National Institutes of Health states that along with fortified cereal, swordfish, salmon, tuna and fortified orange juice are all sources of vitamin D.
