Asparagus

A Natural Diuretic

Asparagus is a very good source of potassium (288 mg per cup) and quite low in sodium (19.8 mg per cup). Its mineral profile, combined with an active amino acid in asparagus, asparagine, gives asparagus a diuretic effect. Although some popular articles on asparagine link this amino acid to the distinct urinary odor that can follow along after consumption of asparagus, research studies suggest that this odor stems from a variety of sulfur-containing compounds. Historically, asparagus has been used to treat problems involving swelling, such as arthritis and rheumatism, and may also be useful for PMS-related water retention.

Food for Healthy Gut Flora

Asparagus contains a special kind of carbohydrate called inulin that we don't digest, but the health-promoting friendly bacteria in our large intestine, such as Bifidobacteria and Lactobacilli, do. When our diet contains good amounts of inulin, the growth and activity of these friendly bacteria increase. And when populations of health-promoting bacteria are large, it is much more difficult for unfriendly bacteria to gain a foothold in our intestinal tract.

Especially if you're thinking about becoming pregnant or are in the early stages of pregnancy, make asparagus a frequent addition to your meals. A cup of asparagus supplies approximately 263 mcg of folate, a B-vitamin essential for proper cellular division because it is necessary in DNA synthesis. Without folate, the fetus' nervous system cells do not divide properly. Inadequate folate during pregnancy has been linked to several birth defects, including neural tube defects like spina bifida. Despite folate's wide availability in food (it's name comes from the Latin word folium, meaning "foliage," because it's found in green leafy vegetables), folate deficiency is the most common vitamin deficiency in the world.
