Why We Don’t Use Sunscreen June 10, 2008
Kate and I are leaving tomorrow morning on a trip to Dallas to be with family and help out with the crisis that’s going on. While we are there, we will be spending some time in the pool, and going on walks.
So we’re going to get some sun. And lots of it! But we won’t be bringing any sunscreen. We will, however, be bringing our cod liver oil.
Some people think I’m crazy not to put any sunscreen on Kate. If we are out in midday sun or we are planning to be out for a long time, I do cover her with a hat and a shade. Otherwise I don’t worry about it — I want her to soak in the sunshine!
The more I read about sunscreen, I really don’t think it’s good for you. It’s carcinogenic! Plus the vitamin D from the sun is so good for you. So you don’t want to block that.
It’s so funny — reminds me of that Woody Allen quote from “Annie Hall” (one of my favorite movies of all time), “Sun is bad for you. Everything our parents said was good is bad. Sun, milk, red meat… college.”
How did they ever convince us all these things are bad?
Here are a few excerpts from a great article on The Healthy Skeptic blog:
… Sunlight is a major source of vitamin D. Insufficient levels of vitamin D can result in osteoporosis, autoimmune diseases and rheumatoid arthritis - among other equally unpleasant and life-threatening conditions. When you put on those high-SPF sunscreens, not only are you increasing your risk for melanoma, you are increasing your risk of developing all of the conditions that can arise from vitamin D deficiency because you are blocking your body’s ability to synthesize vitamin D.
And while it is possible to obtain vitamin D from food, it is only present in large amounts in certain kinds of seafood - which many people do not consume regularly. The highest sources for vitamin D in food are anglerfish liver, cow’s blood (I’m not joking) and high-vitamin cod liver oil (HVCLO). It is also present in more modest amounts in chum salmon, Pacific marlin, herring, bluefin tuna, duck eggs, trout, eel, mackerel and salmon.
I’m going to go out on a limb and guess that most Americans aren’t eating these foods on a regular basis. The lack of adequate intake of vitamin D in the diet, combined with habitual use of high-SPF sunscreen and/or lack of exposure to the sun is a perfect recipe for increasing the risk of cancer for children and adults alike.
I don’t know about you, but we don’t eat a lot of anglerfish and cow’s blood around here. We do take our cod liver oil, which turns out is a very good thing to do because you need the right ratio of vitamin D and vitamin A:
Before closing, I must mention (briefly) the issue of vitamin D toxicity. Vitamin D is widely considered to be the most toxic of all vitamins, and dire warnings are often issued to avoid excess sun exposure and vitamin D in the diet on that basis. The discussion of vitamin D toxicity has failed to take into account the interaction between vitamins A, D and K. Several lines of evidence suggest that vitamin D toxicity actually results from a relative deficiency of vitamins A and K.
So, the solution is not to avoid sun exposure or sources of vitamin D in the diet. Rather, it ensure adequate vitamin D intake (through sunlight and food) and to increase the intake (through diet and/or supplements) of vitamins A & K.
Interestingly, I have noticed that since I have been taking cod liver oil, I don’t burn anymore. Kate and I went for a long walk a while back — two hours in bright midday sun and I was not wearing a hat. (Kate was under a sunblock shaded cover I have for her stroller.) We came home and Seth commented on how red my face was. We were both sure I was going to have a bad sunburn.
A couple of hours later, the redness was gone. No burn! That has never happened to me before.
Before I started eating the WAPF way, I definitely would have gotten a sunburn in those conditions. I’m not sure what it is about my diet that is preventing the burn — but I think it has something to do with all the good fats I’m eating (whole milk, cream, butter, coconut oil, meats with skin and fat). I think it also has a lot to do with the cod liver oil.
My inlaws said something interesting recently. They went to Costa Rica last fall and for the first time ever, they did not burn. They insisted that the only thing they had changed in their diet was the inclusion of daily cod liver oil.
PS: Since we’ll be gone all week, I probably won’t be posting. See you next week!
