Dietary Fat
In plain words
The short version
Fat-soluble vitamins need fat in the same meal to be absorbed at all.
Why it's green
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Safety profile
Vitamins A, D, E and K, and carotenoids like beta-carotene and lycopene, are absorbed only when fat is present in the same meal. A fat-free salad of leaves and tomato delivers a fraction of the carotenoids that the same salad with oil does.
