These citrus gems contain calcium and folate, two nutrients that are important for post-menopausal women and women of child-bearing age. One fresh lime contains 22 milligrams of calcium and over five micrograms of folate. Not bad for a tiny little fruit!
The peels of citrus fruits contain an inhibitor of melanin production. With age and UV ray exposure, melanin, which gives skin its pigment, can build up and deposit itself as spots on your skin. Treating skin to a mask with bits of lime peel in it could reduce this hyperpigmentation.
The limonoid compounds in limes have been shown to prevent cancers of the colon, stomach and blood. Though the exact mechanism is unknown, scientists have observed that antioxidant limonoids also cause cancer cell death. Lime limonoids also stay active longer in your bloodstream, mopping more free radicals than green tea or dark chocolate.
Fresh or from concentrate, lime juice contains more citric acid than orange or grapefruit juice. Citric acid is a natural inhibitor of kidney stones made of crystallized calcium. Go for fresh lime juice squeezed into water, as opposed to commercial limeades, for maximal benefits.
The primary flavonoid found in the limes, known as hesperidin, has been shown to lower cholesterol and triglyceride levels in animals fed a high-cholesterol diet. Get the most hesperidin out of heart-smart limes by eating as much of the white pith as possible.
