Another benefit of fats is that they help with the absorption of certain key vitamins, the fat-soluble ones, like vitamin A, vitamin D, vitamin E, and vitamin K. The very important antioxidants, carotenoids, are also fat soluble. They include beta-carotene (the orange in carrots and the provitamin converted to vitamin A in the body), lutein (a pale yellow in sweet corn, and found in especially high levels in spinach), lycopene (the red color from tomatoes), and zeathanthin (a red-orange compound found in high amounts in leafy green vegetables, among others).
