Dr. Jonathan V. Wright [a prolific writer]
discussed what he calls the “DNA Repair Group” – the foods and supplements that everyone (and especially those who get a lot of sun exposure) should be consuming in abundance. Vitamins C and E are very important to relieving stress to the skin.
But according to Dr. Wright, folic acid deficiency is “a major contributor to skin cancer risk.” He says, “Folic acid is destroyed rapidly byheat, cold, and exposure to light, including sunlight. So it’s sunlight’s destructive effect on folic acid inthe skin, not the actual sun exposure itself, which accounts for a significant part of the skin cancer problem.
Folic acid (along with vitamin B12 and zinc) is absolutely key to DNA reproduction and repair .”The best dietary sources of folic acid include spinach and other dark green vegetables, brewers yeast,

lima beans, cantaloupe, watermelon, wheat germ, and liver from organically raised animals. In addition, Dr. Wright suggests supplementing with 1,000 mcg of folic acid per day, and more if you spend a good amount of time in the sun or have a family history of skin cancer
