For a while now we have know that there is a link between obesity and a deficiency in vitamin D. A relatively recent study found vitamin D supplementation resulted in weight loss in obese and overweight people who are vitamin D deficient. Unlike most vitamins, vitamin D can be manufactured by your body, provided you're exposed to sunlight. However the use of sunscreen reduces your skin's ability to make vitamin D by 90 to 99 percent, depending on the level of SPF and thoroughness of application. Even without the use of sun screen it's tough to catch the right rays. The sunlight you're most likely to get on a daily basis—in the early morning and late afternoon—is too weak to generate enough vitamin D. Not to mention that air pollution can filter out some of the UVB rays, so less of them are able to reach your skin at any time of day. So how do we get an ample supply of this sunshine vitamin?
There are many dietary supplements that you can purchase to boost your vitamin D levels along with foods rich in vitamin D such as:
Tuna canned in water
Sardines canned in oil
Milk or yogurt (fortified with vitamin D)
Beef or calf liver
But do not stop there; why not take it outside too. Now that winter is winding down and spring is evidently on the horizon that means we can slowly begin to put down the winter parkas and whip out the wind breakers for a walk, jog or run outside; maybe along the sea wall? There are many other health benefits to a steady production of vitamin D within your body that include the regulation of calcium and phosphorus absorption which in turn promotes the maintenance of healthy bones and teeth. There are many, many more benefits to this sunshine vitamin and it is definitely worth learning more about to assist you on your health and fitness journey coupled with your personal training here at GWA!
