This Skin-Healthy Diet Tweak Is Totally Nuts

In the hierarchy of the nut realm, the walnut is king. The crunchy crown jewel is loaded with antioxidant polyphenols that fight free radicals and help prevent them from damaging cells. The antioxidant content in walnuts is almost double that of other nuts, according to researchers. Plus, they’re rich in anti-inflammatory omega-3 fatty acids, alpha-linolenic and linoleic acids. Linoleic acid, which is often lacking in acne-prone skin, helps regulate sebum and supports the skin barrier.

A favorite among bridge players and vegans, the cashew contains a laundry list of skin-loving minerals and bioactive compounds including oleic acid, linoleic acid, phytosterols, phenolics, tocopherols, magnesium, iron, and phosphorous. Cashews are rich in zinc, a mineral that aids cell growth and tissue repair, protects against oxidative stress, and gives acne regimens a boost. They’re also good sources of selenium, which guards cell membranes, enhances the skin’s elasticity, and is an essential component in the enzyme glutathione, which regulates pigment. The most abundant vitamin in cashews is the cell-protecting antioxidant, Vitamin E. As with other nut varieties, leaving the skin on boosts the antioxidant value.

Everybody’s favorite nut, the almond has earned its adoration. Its unique nutrient profile—protein, monounsaturated fats, essential nutrients like vitamin E and magnesium, all in a fiber-dense package—make the almond an A+ snack. It also ranks low on the glycemic scale and exerts its blood-regulating influence on other foods. Studies show that when eaten with high-glycemic foods like bread and pasta, the almonds keep glucose from spiking. That makes almonds excellent for protecting against the age-accelerating process known as glycation, in which sugar binds to proteins, causing collagen degradation.
