After years of being maligned, fat is making a comeback. It's the macronutrient necessary for absorbing fat-soluble nutrients like carotenoids, the antioxidant the body converts to vitamin A. This family of antioxidants gives fruits and veggies their orange and red hues, so the produce containing these antioxidants is easy to spot.Take tomatoes, for instance. They're known for being high in the antioxidants lycopene and beta carotene, two types of carotenoids. But since lycopene and beta carotene are fat soluble, tomatoes need to be paired with a bit of fat to absorb these important nutrients. Spritzing a little olive oil over your tomatoes adds flavor and will help you reap the benefits of this fruit disguised as a veggie. Or go all out and make a Caprese salad.
