Squash
Squash is a good source of vitamin C and carotene. The six carotenoids (out of the 600 found in nature) found most commonly in human tissue — and supplied by squash and other gourds — decrease the risk of various cancers, protect the eyes and skin from the effects of ultraviolet light, and defend against heart disease.
One of them, alpha-carotene, helps slow down the aging process. Butternut squash is the strongest source of these nutrients, but you can also try acorn, Hubbard, delicata, calabaza, and spaghetti squash.
