If you've noticed that what you eat affects not only your waistline but also your skin, hair and nails, you are not alone. Your skin is often a reflection of your health—and that's a good thing. Changing up your diet is an underrated, efficient route to clearer, younger looking skin. Plus, it's a lot cheaper than all those lotions and potions lining the counters. The health of every organ affects our appearance. Just as eating well can keep our heart in tip-top shape, we can shave years off our looks if we chew the right things. Our skin is barraged inside and out by stress, hormones, junk food and weather, just to name a few. A healthy diet helps your skin withstand these insults via nutrients that help repair, maintain and enhance it.
