Limes are a good source of magnesium and potassium, which promote heart health. Potassium can naturally lower blood pressure and improve blood circulation, which reduces your risk of a heart attack and stroke.
As with most fruits, there is only a trace amount of fat in limes.
Vitamins and Minerals
Limes and lemons, like all citrus fruits, are an excellent source of vitamin C. Just one lime contains just under 20 milligrams, a third of the daily recommended amount of vitamin C for adults. Vitamin C helps with cell growth and repair, such as wound healing, and supports the immune system. Limes are also a good source of folate, vitamin B6, and potassium.
While limes do contain healthful phytonutrients, we typically consume them in amounts too small to offer much benefit. Their biggest contribution may be in replacing oil or salt in a dish to cut its overall fat or sodium content.
Fights Oxidative Stress
Limes contain antioxidant compounds, which means they can help cells fight damage caused by free radicals in the body. In turn, this can help prevent chronic diseases and signs of aging.
