The Best Anti-Aging Foods

Best for Firming: Kale and Spinach

Why they work: These vital veggies contain special phytonutrients, or antioxidant compounds, that help guard against damage caused by the sun. Spinach is loaded with beta-carotene and lutein, two nutrients that have been shown to improve skin elasticity, according to a study in the Journal of Agricultural Food Chemistry.

Serve yourself: Every week, aim for three cups of either kale or spinach, or a combination of both, suggests Newgent.
