Asparagus is a very good source of fiber, folate, vitamins A, C, E and K, as well as chromium, a trace mineral that enhances the ability of insulin to transport glucose from the bloodstream into cells. A particularly rich source of glutathione, asparagus may help protect against and fight certain forms of cancer, such as bone, breast, colon, larynx, and lung cancers.
Asparagus is packed with antioxidants, ranking among the top fruits and vegetables for its ability to neutralize cell-damaging free radicals. Asparagus contains high levels of the amino acid, asparagine, which serves as a natural diuretic. Increased urination not only releases fluid, but helps rid the body of excess salts. This is especially beneficial for people who suffer from edema, (an accumulation of fluids in the body’s tissues), and those who have high blood pressure or other heart-related diseases.
