We’ve all heard that food is the best medicine, but a new study out of the University of Arizona found that nutrient-dense foods could also be useful as topical applications. According to researcher Sally Dickinson, a naturally occurring compound in broccoli is loaded with chemopreventive properties. The nutrient is known as Sulforaphan, and if added to the list of ingredients in sunscreen, could dramatically increase the products cancer-preventing properties. “Sulforaphane is the kind of compound that has so many incredible theoretical applications if the dosage is measured properly,” Dickinson says. “We already know that it is very effective in blocking sunburns, and we have seen cases where it can induce protective enzymes in the skin.”
