7 Foods That Help Protect Your Skin from Harmful UV Rays
You know that a lot of foods are really good for you, but did you know that several actually have properties that can help protect your skin from the sun? Considering the intense rays many of us are exposed to this summer, everything helps, right?
Here’s a little more about how this works, and what foods to add to your diet for a little extra skin protection.
Science Indicates Foods Can be Skin Protective
According to the University of Maryland Medical System, eating certain foods can help protect against skin cancer. Though we don’t yet have scientific tests that have measured and compared various foods and their ability to protect the skin, research has shown that antioxidants may offer protection.
A study published in 2010 also came to similar conclusions, though it added that food nutrients can protect not only against skin cancer, but photo-oxidative damage that leads to skin aging. Scientists noted in the study that antioxidant vitamins, minerals, and phytochemicals, in addition to essential fatty acids, have demonstrated protective properties. They added that the presence of these nutrients in the traditional Greek-style Mediterranean diet may have contributed to the low levels of melanoma there, despite the population’s exposure to high levels of solar radiation.
“The increasing incidence of skin cancer despite the use of externally applied sun protection strategies,” said Niva Shapira, lead author, “alongside research showing that nutrients reduce photo-oxidative damage, suggest nutritional approaches could play a beneficial role in skin cancer prevention.”
Some of the Best Choices
Though many foods may offer sun protection, below are a few of those with the most promise so far, though we’re always finding out about new super foods.
1. Apples. Surprised? A Japanese study actually found that apple polyphenol extracts, particularly flavonids called “procyanidins,” inhibit skin cancer in mice. Another polyphenol, quercetin, protected DNA from human skin cancer cells.
2. Green Tea. Yes, it’s a beverage, but it’s got powerful antioxidants. The University of Maryland Medical Center says it contains polyphenols, potent antioxidants that have shown in studies to help prevent skin tumors from starting or growing.
3. Dark Chocolate. Another reason to indulge now and then, dark chocolate has powerful antioxidants that may help protect from sunburn.
4 and 5. Olive Oil and Tomato Paste. Did you need another reason for using these health-filled goodies, often critical in flavorful pasta sauces? Here it is. German studies found that those subjects consuming about 2 teaspoons of olive oil and about ¼ cup of tomato paste daily for 10 weeks experienced 35 percent less reddening when exposed to sunlamps than those who didn’t eat these items. In addition, research from the University of Michigan found that lycopene and other antioxidants in tomatoes can help prevent the skin from becoming sunburned.
6. Broccoli. Research from the Johns Hopkins School of Medicine exposed areas of volunteers’ skin to intense ultraviolet light one to three days after applying a broccoli-sprout extract to the same area. The extract was all but rubbed away by the time of the exposure, but those areas had, on average, 37 percent less redness and inflammation. Simultaneous animal studies showed that mice treated with the extract had significantly fewer and smaller skin tumors after exposure to UV rays. Scientists say that broccoli turns on the body’s natural cancer-fighting machinery, and once turned on, it works for days. The lead researcher of the study recommended eating one-half cup of broccoli each day to protect against skin cancer.
7. Green, Leafy Vegetables. This includes kale, spinach, and chard. According to an Australian study, these could decrease skin cancer risk. Scientists studied over 1,000 adults living in Australia over an 11-year period, and found that increasing intakes of green leafy vegetables was associated with a 41 percent decreased risk of skin cancer. These vegetables are rich in folic acid, which plays a key role in DNA synthesis and repair. In addition, researchers also examined those participants that previously had skin cancer, and found that those who did had a 55 percent decrease in skin cancer with increasing intakes of green leafy vegetables. “Our findings show that higher intakes of green leafy vegetables may help prevent Squamous cell carcinoma (SCC) tumors among people who have prior skin cancers,” the researchers stated.
