According to the U.S. National Institutes of Health's National Library of Medicine, 42 percent of Americans meet the criteria for clinical vitamin D insufficiency.
However, if you live in the northern hemisphere at this time of year, almost everyone runs the risk of being short of the 'sunshine' vitamin. Apart from popping a daily vitamin D supplement, what's the best natural way of getting a good vitamin D intake (in the absence of sunshine)?
Egg Yolks: One egg yolk contains 10 percent of your daily value of vitamin D.
Salmon: Salmon is not only a great source of omega-3, one three-ounce serving also provides 71 percent of your daily intake of vitamin D.
Tuna and Sardines: Although not quite as rich in vitamin D as salmon, this versatile fish makes it easy to up your vitamin D intake in sandwich or sushi form.
Mushrooms: This superfood is great for vitamin D. A handful of white mushrooms offers 46 percent of your daily vitamin D needs, so add some to your next soup, pizza, or scrambled eggs.
Milk: Milk is one of the most well-known sources of vitamin D, but if you don’t consume dairy, don’t panic, the other options in this list are great choices too!
