Dull Skin

Combating tired, dull skin is as simple as upping your fruits-and-veggies intake. "A recent study from St. Andrews University found that people who upped their intake of produce for six weeks were rated as more attractive," says Sass. "The scientists tracked the diets of 35 people, took photos of them, and asked others to rate the pictures. Volunteers who ate an average of 2.9 more portions of fruits and vegetables each day were rated as healthier looking, and those who downed an extra 3.3 portions per day were rated as more attractive."

According to Sass, this isn't the first study of its kind — a previous one led by researchers at the University of Nottingham found that participants who ate a healthy diet rich in fruits and vegetables were rated as more attractive. There's no real downside to a produce-heavy diet, so this is just one more reason of many to eat more servings of fruits and vegetables.
