Colorful Foods Contribute to Prettier, Smoother Skin
If you want a smoother, clearer complexion, Jessica Wu, M.D., assistant clinical professor of dermatology at USC Medical School and a dermatologist in Los Angeles, encourages you to toss all these fortifying Feed Your Face foods into your grocery cart.
Definitely one of your skin’s best defenses, tomatoes contain a powerful antioxidant called lycopene. While studies have not yet been entirely conclusive, many suggest that lycopene may be responsible for helping to protect the skin against sun damage.
Lycopene is best absorbed by the body when it has been cooked or processed, so eating tomato sauce, tomato paste, and ketchup is likely to be more effective than just eating raw tomatoes when trying to safeguard your skin against harmful UV rays. Lycopene is also fat soluble, which means that it is absorbed more easily when consumed with fat, such as eggs, avocado, and olive oil.
Sometimes it gets a bad rap, and even though red meat does contain saturated fat and cholesterol, lean red meat is one of Dr. Wu’s favorite Feed Your Face foods because it’s so high in protein and zinc. In fact, recent studies suggest that red meat may be even better at treating acne than antibiotics.
To produce collagen, your skin needs the amino acids glycine and proline, and the protein in red meat has the highest concentration of these two amino acids. The mineral zinc is also crucial for collagen production. “It’s an essential cofactor,” says Dr. Wu. “Without enough zinc, it’s difficult for the skin to make collagen. Plus, zinc is a natural anti-inflammatory.” And vegetarians don’t need to miss out. Dr. Wu adds that high concentrations of glycine can also be found in seafood, proline in cottage cheese and cabbage, and zinc in lentils, kidney beans, and raw oysters.
It’s no secret that green tea is an antioxidant powerhouse. Its strong anti-inflammatory and anti-aging effects are attributed to its high concentration of catechin compounds. Studies have shown that green tea can be used both orally and topically to help protect the skin from sunburns and UV-associated skin cancers. Research also suggests that drinking one cup of green tea twice a day over the course of six months may actually reverse sun damage and significantly improve any problems you have with redness and broken capillary veins.
As long as we’re going green, let’s talk about how these low-calorie beans can help you grow thicker hair and healthier nails. Green beans are a star Feed Your Face food because they’re one of the richest sources of silicon — not to be confused with silicone, which is found in bad lip jobs and breast implants! The USDA has not yet established recommended daily intakes (RDIs) of silicon, but 10 mg per day seems to be adequate for strengthening hair and nails, according to recent studies. Dr. Wu recommends choosing organic green beans, since they retain more silicon from the soil. Don’t like green beans? You can also get your silicon fix from volcanic mineral waters such as Volvic, which contains 14.5 mg per liter.
