Just as an unhealthy diet can have a negative effect on your skin and health, a healthy diet high in antioxidant-rich foods can help protect your body, even from the sun. Since antioxidants help reduce inflammation and free radicals, loading your diet with them will go a long way against sunburn and skin damage as a result of UV rays.
To be clear, I'm not saying you should completely replace your daily sunscreen with food, but what you eat can offer additional protection for your skin. So if you're looking for some ingestible sun protection, add these six sun-friendly foods to your next shopping list.
1. Berries & stone fruits
Strawberries, blueberries and cherries contain high levels of vitamin C, which can reduce free radical damage caused by exposure to UV radiation. Vitamin C also stimulates collagen production, important for skin’s youthful appearance. As a bonus, cherries contain melatonin, which protects skin from UV radiation and repairs sunburn damage.
2. Leafy greens
If it’s green and it's got leaves, chances are it’s good for sun protection. According to one study, spinach, kale and swiss chard can reduce the risk of squamous cell skin cancer by 50%. Broccoli is also a good choice: it's full of sulphoraphane, an antioxidant that helps your cells protect themselves against UV radiation.
Fresh herbs like parsley, basil, sage and rosemary are also packed with free radical-fighting, skin-protecting antioxidants. Not sure where to start? Check out our guide to cruciferous vegetables.
3. Red & orange produce
The antioxidant lycopene has been shown to protect the skin against sunburn and is at least twice as effective an antioxidant as betacarotene when it comes to blocking UV light. It also helps rid the body of free radicals. Chow down on tomatoes, papaya, guava, red bell peppers and pink grapefruit. Watermelon is an especially good choice: it contains 40% more lycopene than tomatoes.
Betacarotene is another antioxidant that has natural sunscreen properties: it's been linked to reduced reactions to sunburns. You can fnd it in carrots, sweet potatoes, squash, pumpkins, mango and apricots.
Spirulna has been dubbed "the next great superfood," and for good reason. This micro-algea — along with chlorella — contains the antioxidant astaxanthin, which has been shown to protect the skin and eyes against UV radiation. It also fights free radicals and inflammation to prevent sun damage by preventing UV-induced cell damage.
If micro-algea isn't exactly your cup of tea, you can find this powerful antioxidant in shrimp and salmon.
As long as it's dark chocolate you're eating, you'll be ingesting plenty of flavanoids, which can improve your skin’s ability protect against sun burns and other UV-induced issues.
Research found that people who ate about one ounce of high-percentage dark chocolate every day for three months could withstand twice the amount of UVB rays before their skin started to turn red, compared to those who didn't.
6. Green & black tea
The myriad health benefits of tea are well-known, but it's nice to know that the cups you're drinking can also help protect against sun damage. Green and black teas are packed with polyphenols that can help stop cancerhelp stop cancer development by limiting the blood supply to the cancerous area.
Green tea can even help prevent non-melanoma skin cancer by enhancing DNA repair.
