Eat yourself beautiful
Nutrition impacts everything; your metabolism, mood, and organs, including your skin. As scientists learn more about diet and the body, it's increasingly clear that what you eat can significantly affect the health and aging of your skin. Here are 11 of the best foods for keeping your skin fresh and glowing.
1. Fatty Fish
Fatty fish, such as salmon, mackerel and herring, are excellent foods for healthy skin. They are rich sources of omega-3 fatty acids, which are necessary to keep skin thick, supple and moisturized. In fact, a deficiency in omega-3 fats can cause dry skin.
The omega-3 fats in fish reduce inflammation, which can cause redness and acne. They can even make your skin less sensitive to the sun's harmful UV rays. Some studies show that fish oil supplements may fight inflammatory and autoimmune conditions affecting your skin, such as psoriasis and lupus.
Fatty fish is also a source of vitamin E, one of the most important antioxidants for your skin. Getting enough vitamin E is essential for protecting your skin against damage from free radicals and inflammation.
Lastly, fish provides zinc, a mineral vital for regulating inflammation, the production of new skin cells and overall skin health. Zinc deficiency can lead to skin inflammation, lesions, and delayed wound healing.
Natalie’s all-time favorite are back again! Getting enough of the monounsaturated fats in avocados is essential to keep skin flexible and moisturized. One study in over 700 women found that a high intake of monounsaturated fats found in avocados was associated with more springy skin. Avocados are also a good source of vitamin E, which is an important antioxidant that helps protect your skin from oxidative damage from sun exposure.
Interestingly, vitamin E seems to be more effective when combined with vitamin C. Vitamin C is also essential for healthy skin. Your skin needs it to create collagen, which is the main structural protein that keeps your skin strong and healthy. A deficiency in vitamin C is rare these days, but common symptoms include dry, rough and scaly skin that tends to bruise easily. Vitamin C is also an antioxidant that protects your skin from oxidative damage — caused by the sun and the environment — which can lead to signs of aging.
Walnuts have many characteristics that make them an excellent food for healthy skin. They are a good source of essential fatty acids, which are fats that your body cannot make itself. In fact, they’re richer than most other nuts in both omega-3 and omega-6 fatty acids. A diet too high in omega-6 fats may promote inflammation, including inflammatory conditions of your skin like psoriasis. On the other hand, omega-3 fats reduce inflammation in your body including in your skin. While omega-6 fatty acids are plentiful in the Western diet, sources of omega-3 fatty acids are rare. Because walnuts contain a good ratio of these fatty acids, they may fight the inflammatory response to excessive omega-6.
Walnuts also contain zinc, which is essential for your skin to function properly as a barrier, as well as necessary for wound healing and combatting both bacteria and inflammation. Walnuts also provide small amounts of the antioxidants vitamin E, vitamin C and selenium, in addition to 4–5 grams of protein per ounce.
4. Sweet Potatoes
Sweet potatoes are an excellent source of beta-carotene, which functions as provitamin A, which means it will be converted into vitamin A in your body. Carotenoids like beta-carotene keep your skin healthy by acting as a natural sunblock. When consumed, this antioxidant is incorporated into your skin and protects your skin cells from sun exposure. This may help prevent sunburn, cell death and dry, wrinkled skin. Interestingly, high amounts of beta-carotene may also add a warm, orange color to your skin, contributing to an overall healthy glow.
5. Red or Yellow Bell Peppers
Like sweet potatoes, bell peppers are an excellent source of beta-carotene, which your body converts into vitamin A. They’re also one of the best sources of vitamin C, necessary for creating the protein collagen which keeps skin firm and strong. A single cup of bell pepper provides an impressive 317% of the RDI for vitamin C. A large observational study in women linked eating plenty of vitamin C to a reduced risk of wrinkled and dry skin with age.
Broccoli is full of many vitamins and minerals important for skin health, including zinc, vitamin A and vitamin C. It also contains lutein, a carotenoid that works like beta-carotene. Lutein protects your skin from oxidative damage, which can cause your skin to become dry and wrinkled. Broccoli florets also pack a special compound called sulforaphane. Sulforaphane is also a powerful protective agent against sun damage by neutralizing harmful free radicals and switching on other protective systems in your body. Evidence suggests sulforaphane may also maintain collagen levels in your skin.
Tomatoes are a great source of vitamin C and contain all of the major carotenoids, including lycopene. Beta-carotene, lutein, and lycopene have been shown to protect your skin against damage from the sun. They may also help prevent wrinkling. Consider pairing carotenoid-rich foods like tomatoes with a source of fat, such as cheese or olive oil. Fat increases your absorption of carotenoids.
Soy contains isoflavones, a category of plant compounds that can either mimic or block estrogen in your body. Isoflavones may benefit several parts of your body, including your skin. One small study in middle-aged women found that eating soy isoflavones every day for 8–12 weeks reduced fine wrinkles and improved skin elasticity. In postmenopausal women, soy may also improve skin dryness and increase collagen, which helps keep your skin smooth and strong. These isoflavones not only protect the cells inside your body from damage but also your skin from UV radiation, which may help prevent some skin cancers.
9. Dark Chocolate
If you need one more reason to eat chocolate, here it is: The effects of cocoa on your skin are pretty phenomenal. Real cocoa powder has so many antioxidants known to make skin less rough and scaly, less sensitive to sunburn and have better blood flow, which brings more nutrients to your skin. One study found that eating 20g of high-antioxidant dark chocolate per day could allow your skin to withstand over twice as much UV radiation before burning versus eating low-antioxidant chocolate. Make sure to choose dark chocolate with at least 70% cocoa in order to maximize the benefits and keep added sugar to a minimum.
10. Green Tea
Green tea may protect your skin from damage and aging. The powerful compounds found in green tea are called catechins and work to improve the health of your skin in several ways. Like several other antioxidant-containing foods, green tea can help protect your skin against sun damage. One 12-week study in 60 women found that drinking green tea daily could reduce redness from sun exposure by up to 25%. Green tea also improved the moisture, roughness, thickness and elasticity of their skin.
11. Red Wine
Red wine is famous for containing resveratrol, a compound that comes from the skin of red grapes. Resveratrol is credited with a wide range of health benefits, among them reducing the effects of aging. It may also slow the production of harmful free radicals, which damage skin cells and cause signs of aging. Unfortunately, there's not much evidence that the amount of resveratrol you get from a glass of red wine is enough to impact your skin. And since red wine is an alcoholic beverage, there are negative effects to drinking it in excess. It's not recommended to start drinking red wine just because of its potential health benefits. However, if you already drink, you might enjoy red wine as your alcoholic beverage of choice.
The Bottom Line
What you eat can have a big impact on your skin health. Make sure you're getting enough essential nutrients to protect your skin. The foods on this list are great options to keep your skin healthy, strong and gorgeous.
