Facts about Sunscreen
As we all know, UV light from the sun’s rays causes skin cancer and prematurely ages the skin. This doesn’t mean that we don’t need some sun. Having about 20 minutes each day is good for us. It boosts our vitamin D levels and improves our overall mood. However, if exposed for more than 20 minutes our immune system will suffer. And so growing up, we have all been taught to lather on a lot of sunscreen and to do it often. Is sunscreen really the best thing for us and our health? What could be lurking in the ingredients that could end up being very harmful to us?
There are 17 ingredients approved by the FDA in sunscreen. 15 of the ingredients are clear chemicals that absorb the UV light. The last 2 are made of minerals that reflect the UV light. Out of the 15 clear chemical ingredients, 9 of them are known as endocrine disruptors. The endocrine system is our bodies’ hormone system. The ingredients in sunscreen interfere with the normal function of our hormones. The most common hormones are estrogen, progesterone, testosterone, and thyroid. It has been found that some endocrine disruptors that act like estrogen can be a huge factor to the development of breast and ovarian cancers in women. While some other endocrine disruptors can increase the risk of prostate cancer developing in men.
With chemical sunscreens, in order for it to be effective it has to be reapplied often. Some sunscreens lose as much as 90% of their effectiveness within an hour. They do a good job with blocking UV light, but they also get used up quickly. The reason is because chemical sunscreens don’t sit on the surface of the skin. In fact, they soak into the skin and quickly find their way into the bloodstream. It flows through the whole body without being detoxified by the liver. These chemicals are then detected in blood, urine, and even breast milk for up to two days after a single application.
This doesn’t happen with the mineral or physical sunscreens. These have the ingredients of zinc oxide and titanium dioxide. They sit on the surface of the skin and physically block UV light instead of being absorbed into the skin and therefore the bloodstream and the body’s systems.
Foods that help protect against sun damage
-Heirloom Tomatoes: Heirloom tomatoes are rich in the antioxidant lycopene. Lycopene reduces UV-induced free radicals by up to 50%. To better absorb the lycopene, it is best to ingest it with fat.
-Watermelon: Watermelon is another good source for lycopene. In order for it to be effective, it is recommended to eat at least three cups of watermelon.
-Bell Peppers: Bell peppers are rich in the antioxidant capsiate. This reduces inflammation from sun exposure, and also decreases UVB-induced skin damage.
Pomegranates: The pomegranate seeds contain polyphenols. This protects the skin from UVB free radicals and also UVA. Having some pomegranate juice is an easy way to get antioxidants. But without the seeds, the juice converts to sugar too quickly which leads to glycation and aging.
Wild Salmon: Wild salmon are rich in omega-3 fats. This reduces inflammation caused by UVB rays up to 52%. It also blocks the release of UV-induced enzymes that eat away at collagen, causing lines and sagging.
