This is because carrots don't contain Vitamin A but a carotenoid called beta carotene which is a “provitamin” — a substance that can be converted into a vitamin.

因为萝卜所含并不是维生素 A，而是一种叫做β-萝卜素萝卜素，它是一种“维生素原”，一种可以转化成维生素物质。

One last thing, the absorption efficiency of carotenoids decreases as the amount of dietary carotenoids increases.

最后一点是，萝卜素吸收效率随着饮食中萝卜素摄入升高而降低。

So, it makes sense that this research from Ohio state found that avocado is a good way to help absorb carotenoids like beta-carotene and convert them to Vitamin A.
