Asparagus is low in calories and carbohydrates, and compared to other vegetables it is relatively rich in protein. One cup of asparagus supplies only 24 calories, almost half of which are derived from protein. Asparagus is an excellent source of potassium, vitamin K, folic acid (263 micrograms per cup), vitamins C and A, riboflavin, thiamine, and vitamin B6. It has an excellent ratio of potassium (288 milligrams per cup) to sodium (19.8 milligrams per up). Asparagus is also a very good source of dietary fiber, niacin, phosphorus, protein, and iron. Historically, asparagus has been used as a diuretic and in the treatment of arthritis and rheumatism. The amino acid asparagine may be responsible for the diuretic effect of asparagus. When this amino acid is excreted in the urine, it gives off a strong, characteristic odor.
