It is likely that a diet including seed oils is responsible for a lot of metabolic disease. I would propose that this includes sunburns, caused by diet more than just staying in the sun by itself. Recently sunscreens that contain Benzene were recalled, so it’s entirely possible that skin cancer was exacerbated by sunscreen itself! Seed oils are very high in Omega-6 that cause inflammation. Seed oils are originally a waste product of industrial processes, not meant for food. If you watch how it’s made you will realize that vegetable oils are not really food. The invention of sunscreen may have even coincided with the growing use of seed oils in the 1930’s. Sunscreen was invented in 1938 in Switzerland by Franz Grieter. He got a sunburn when hiking in the mountains and created a cream to help him prevent it. In the 1930’s Weston A Price was also visiting Switzerland and found a marked difference in the diet between isolated mountain communities and modern city dwellers. The diet of isolated mountain living swiss was noted as: “primarily consisted of dairy products (raw milk, butter, cream and raw milk cheese) from cows grazing on lush alpine slopes, and rye bread, or roggenbrot, from rye grown in the valley. They ate meat about once a week, usually veal, using all the parts and making soup with the bones, and some vegetables during the summer months.” The diet of city dwelling “modernized swiss” was described that they: “got their food from stores selling sugar, white flour, pastries, jams and jellies, canned condensed milk, canned foods and vegetable oils.” This looks similar to the extreme difference between an ancestral diet and a modern food diet. A number of other bloggers and twitter users have found that they have not gotten sun burn, or not as severe a reaction to the sun when seed oils were removed from their diet as well. Eating animal saturated fat could be protective, natural vitamin D is necessary for good health and sunscreen really is the new margarine.
