Short Winter Days Mean It's Time to Top Up Your Vitamin D
When the sun is not enough, add Vitamin D from food sources and supplements
Bellingham, WA (Vocus) October 18, 2010
As we approach the winter solstice – the shortest day of the year – it's clear that in many areas of North America, sunshine is in short supply. What's more startling is that many North Americans – studies suggest 30-50% – are deficient in the sunshine vitamin, Vitamin D.
According to nutrition expert Gloria Tsang, founder of HealthCastle. com, Vitamin D deficiency is an issue all year long, not just during winter days with few sunshine hours – but the winter season is an especially important time to ensure good Vitamin D levels, since the sunshine vitamin helps protect against winter flu. "We call Vitamin D the sunshine vitamin," Tsang says, "But the reality is that most people don't get enough Vitamin D from the sun at any time of year – especially since it's now so important to protect our skin from the damaging effects of the sun. We can get some Vitamin D from food sources, but the truth is that just about everyone should be taking a Vitamin D supplement, too."
In addition to helping fight the flu, Vitamin D has other important effects in the body. It aids calcium and phosphorus absorption, helping prevent bone diseases like rickets and osteoporosis, and studies have shown that is has a strong association with lowered cancer risk. Here are 5 key ways to get more Vitamin D:
Feast on fish: Fatty fish, like salmon, tuna, sardines, and mackerel, as well as cod liver oil, are the best food sources of Vitamin D.
Enjoy eggs: Egg yolks contain small amounts of Vitamin D3.
Find fortified foods: Milk fortified with Vitamin D virtually eliminated rickets in the 1930s, and is still a prime source of Vitamin D today. Other Vitamin D-fortified foods include breakfast cereals, yogurt, and orange juice.
Munch on mushrooms: Some mushrooms contain Vitamin D2, including some mushrooms grown in conditions specifically designed to boost Vitamin D content.
Be safe; take a supplement: Expert opinions vary on how much Vitamin D we need (some experts recommend up to 1000 IU per day for adults), but most agree we're not getting enough. Since it's hard to absorb Vitamin D from food sources, your safest best is to take a supplement, especially in the winter.
Of course, we all get some of our Vitamin D supply from the sun – but increasing your sun exposure to up your Vitamin D intake is not a good idea, since the potential risks to your skin outweigh the benefits of the additional Vitamin D. Focus on eating Vitamin D-containing foods instead, and top up your intake with a good supplement. More healthy eating tips from registered dietitians are available at http://www.
