It's common knowledge that foods with high trans and saturated fat contents (like french fries, pizza and potato chips) are to be avoided for a healthy diet. But healthy fats are a necessary part of a healthy diet and they're especially beneficial for your skin. Healthy fats contain monounsaturated and polyunsaturated fats, which "are anti-inflammatory, reduce the risk of cardiovascular disease, and are full of healthy nutrients," says dietitian Dana Hunnes. These fats are often referred to as fatty acids, and the foods that contain them are amazing for sagging skin.

Olives
"Olives are a rich source of vitamins A and E, both of which protect the oils on the surface of your skin from free-radical damage," says registered holistic nutritionist Peggy Kotsopoulos. "The rich phenol content [in oilves] protects skin against oxidization. It helps repair cells, protects against damage and soothes the skin, helping it renew and regenerate."
Walnuts
Walnuts are rich in omega-3 fatty acids. "Consuming foods rich in omega-3 fatty acids may lead to smoother, younger-looking skin with a visible reduction in inflammatory skin conditions like acne and psoriasis," says health expert Chris Kresser.
Olive Oil
Olive oil, a common ingredient in the popular Mediterranean diet, is rich in monounsaturated fats. “Olive oil contains potent antioxidants,” says dermatologist Elizabeth Tanzi. “These include vitamin E and polyphenols, which help to gather and neutralize free radicals that can otherwise damage the skin and advance the appearance of aging.”
Avocado
"[Avocados] provide healthy monounsaturated fats that maintain cell membranes, helping skin stay soft, smooth, and hydrated," according to dermatologist Charles Crutchfield III. "They're also rich in phytochemicals that serve as strong antioxidants that protect the skin from damage, along with vitamins and minerals that help skin repair damage when it does occur."
Incorporate these anti-inflammatory healthy-fats into your diet and you'll have firmer skin in no time!
