The rising rate of skin cancer has put using sunblock rightup there with flossing your teeth when it comes to healthyhabits. In 2002, 50 percent-- approximately 1.1 million cases--ofall cancers in the United States were skin cancers, of whichnearly 10,000 cases were fatal. It is easy to understand whymany people have become fearful of the sun's warmth and glow.

However, it is not commonly appreciated, especially amongtraditional medical doctors, that the food you eat is farmore important to the development of skin cancers than sunexposure.

At the beginning of 1900 we had very little processed vegetableoils in our diet. Now vegetables are great and we all needthem every day, but when they are processed and refined andconsumed in large amounts they can cause major health problems.

Most vegetables are very high in omega-6 fats. In the last100 years the U.S. population has gone from consuming virtuallyno vegetable fats to consuming more than 70 pounds per year.Fats from corn oil, safflower, sunflower, sesame and otheroils are virtually 100 percent omega-6 fats.

This high consumption of omega-6 fats totally distorts theimportant omega 6:3 ratio, and this ratio is one of the keysto obtaining any type of cancer, but especially skin cancer.

So not only will we benefit from consuming additional omega-3fats, but it is vital to reduce the omega-6 vegetable oilsas much as possible. Ideally, the ratio should be 1:1, butmost Americans have a 15:1 ratio. The Japanese are the longest-livedculture on earth, and their ratio is about 3:1.

If you don’t believe me on this one, I encourage youto check out one of the top cancer journal articles CancerRes 2000 Aug 1;60(15):4139-45:

"Epidemiological, experimental, and mechanistic dataimplicate omega-6 fat as stimulators and long-chain omega-3fats as inhibitors of development and progression of a rangeof human cancers, including melanoma."

Ten years ago an Australianstudy showed a 40 percent reduction in melanoma for thosewho were eating fish--and this was without any attention tolowering omega-6 fats.

Two years ago, the prestigious National Academy of Sciencespublished a comprehensivereview showing that the omega 6:3 ratio was the key topreventing skin cancer development.

So, do I recommend you pop some fish oil pills and go outand get as much sun as you would like?

Absolutely not.

You must exercise caution. At the beginning of the seasongo out gradually, perhaps as little as 10 minutes a day. Progressivelyincrease your time in the sun so that in a few weeks, youwill be able to have normal sun exposure with little riskof skin cancer.

Remember never to get burned, that is the key.

Remember also never to use sunscreen, another key. You cancreatively use your clothing to block the sun’s raysduring your build-up time.

The bottom line is: please avoid getting sucked into thehype that sunlight is dangerous. It is only dangerous if youare clueless about fat nutrition, which most medical doctorsare. If you choose to ignore your omega 6:3 ratio and stayout of the sun, you could limit your risk of skin cancer,but is that worth the risk of getting MS, breast or prostatecancer?

I think not.

So get yourself some high-quality krill oil.
