Ever wonder if the bags of greens in the front of the supermarket shelf that are exposed to the light are more nutrient-dense than the ones in the back in the dark? Me neither, but researcher Gene Lester did. He found that just 24 hours of light exposure enhanced the greens’ nutrients. He also discovered that baby spinach is more nutrient-rich than mature spinach. So go get your baby greens, from the front of the display, and eat up!
