A half of cup of asparagus has only 20 calories and 2 grams of fiber. Asparagus is a good source of dietary fiber, folic acid, and vitamins C, E and B6. One more benefit of asparagus: it contains high levels of the amino acid asparagine, which serves as a natural diuretic, and 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. Keep in mind these cooking tips that preserve antioxidants and keep your preparation healthy:
- Roast, grill or stir-fry your asparagus. These quick-cooking, waterless methods will preserve the high nutritional content and antioxidant power of asparagus.
- Enjoy your asparagus without salt, butter or sauces to get the most out of its diuretic properties, as salt can cause water retention in some people.
