Nutritionist Sarah Ann Macklin’s food for thought

Sweet potato

A superfood for the skin, sweet potatoes contain high levels of beta-carotene. As a precursor of vitamin A, beta-carotene helps the body combat harmful free radicals.

Green tea

Packed with polyphenols and powerful catechins, green tea prevents free radicals from harming healthy skin cells.

Tomatoes

With plenty of lycopene (a bright red carotene and carotenoid pigment), tomatoes can limit oxidative damage of the skin caused by sun exposure and air pollutants.

Walnuts

Scoring high in omega-3 fatty acids, this nut not only lessens skin inflammation, but also promotes collagen production within the skin.
