Summer is here and you probably spend more time outdoors. That‘s good news. We can all use the extra vitamin D, according to new research out of Stanford.

In fact, a new study found that women who took vitamin D/calcium supplements cut their risk of developing melanoma, an aggressive form of skin cancer. In fact, they cut their odds by 50 percent! And these were women considered "high-risk" for developing melanoma.

Your body, of course, naturally converts sunshine into vitamin D. So it stands to reason that a little unadulterated sunshine is good for you. It may even protect you against skin cancer. Sounds paradoxical, I know. But experts believe vitamin D blocks cells in your body from mutating, including your skin cells.

So this summer, aim to spend 20 to 30 minutes outside each day without sunscreen. Morning light is generally gentler. This will give you about 10,000 IU of vitamin D3. You can also get vitamin D into your diet by eating more eggs. Vitamin D is naturally found in egg yolks. Also, try to eat more salmon, tuna, and sardines.

Also, if you‘re going to the beach, you will need sunscreen at some point. You‘ll want to look up the safest sunscreens that don‘t contain hormone disruptors. Visit the Environmental Working Group‘s website at www.ewg.org for a list of the safest brands on the market.

So if you haven‘t yet joined the vitamin D bandwagon, now‘s the time to hop on. Go for up to 5,000 IU of vitamin D3 (the form of vitamin D most readily absorbed by the body). You can also get vitamin D into your diet by eating more eggs (naturally found in yolks) and fatty fish such as salmon, tuna, and sardines.
