Foods for Healthy Skin: You Are What You Eat
What Are Foods for Healthy Skin? continued...
The best-known essential fatty acids are omega 3 and omega 6, which must be in balance for good health (and good skin). Though we all seem to get enough omega 6, Heller says many people lack omega 3s. Fish, walnut, and flax seed oil are among the best sources.
Healthy Oils. These contain more than essential fatty acids. Eating good-quality oils helps keep skin lubricated and keeps it looking and feeling healthier overall, Lipski tells WebMD.
Which oils are the right oils for healthy skin? Lipski says those labeled cold pressed, expeller processed, or extra virgin are the ones to look for.
"When an oil is commercially processed, the first thing they do is add solvents and raise them to really high temperatures, then put it though five or six processes. Important nutrients are lost," says Lipski.
By comparison, she says when oils are prepared by the cold-press or expeller process, or, in the case of olive oil, are extra virgin, preparation involves only pressing, heating, and bottling.
"You get all the nutrients that are not only good for your skin, but good for your body," says Lipski.
Since any fat, even a healthy one, is high in calories, experts remind us that we don't need more than about two tablespoons a day.
Whole-wheat bread, muffins, and cereals; turkey, tuna and brazil nuts. The mineral selenium connects all these foods for healthy skin. Experts say selenium plays a key role in the health of skin cells. Some studies show that even skin damaged by the sun may suffer fewer consequences if selenium levels are high.
For instance, in two clinical trials, researchers at Edinburgh University showed that when levels of selenium were high, skin cells were less likely to suffer the kind of oxidative damage that can increase the risk of cancer. The results were published in 2003 in both the British Journal of Dermatology and the journal Clinical and Experimental Dermatology. And a group of French researchers found that oral doses of selenium, along with copper, vitamin E and vitamin A could prevent sunburn cell formation in human skin.
