Key lime pie - that's all the reason one needs to love this zesty tropical fruit, but it has innumerable other uses in dishes ranging from breakfast smoothies to lime-sprinkled salmon on the grill. The nutritional benefits derived from limes are every bit as important: antioxidants, flavonol glycosides, kaempferol, and vitamin C, which staves off colds and flu, eases arthritis pain, and ultimately may prevent many of diseases such as heart disease, stroke, hardening of the arteries and skin, stomach, lung, breast, colon, and mouth cancers. With every study conducted, scientists are turning over more evidence that this small, green tropical fruit may have even more mighty health advantages.
