I am not a nutritionist, but I can tell you that through my research I have found that there are health benefits associated with each of the ingredients that make up a Caprese. Tomatoes are high in vitamin C and are a good source of potassium and vitamins A and K. They also contain antioxidants that help ward off cancer and keep your heart healthy. Basil contains essential oils which are rich in antioxidants, vitamins and magnesium and it is an excellent anti-inflammatory. Mozzarella is a relatively low-calorie cheese and is an excellent source of calcium. As with anything, it is good to eat it in moderation.
