Lime, a type of citrus fruit, is an excellent source of antioxidants. If the acidic taste scares you from sucking a lime fruit, squeezing a little lime juice into a glass of warm water is a good beverage. And you’ll still enjoy the nutritious benefits of lime. Antioxidants protect your body by preventing or stopping damage caused by free radicals, or chemicals that harm cells. Lime rejuvenates the skin, improves digestion, helps with weight loss, lowers blood sugar, and fights common infections like cold.
