There are so many healthy reasons to eat vegetables that it feels redundant to keep enumerating them. But if a stronger immune system, cancer-fighting antioxidants and heart-healthy fiber aren't reason enough for some, perhaps we can appeal to their vanity: a study published in the journal Evolution and Human Behaviour found that eating foods high in carotenoids — a nutrient found in some fruits, leafy greens and root vegetables — gave them a healthy glow that rivaled a sun tan and made them more attractive in tests.
