When asparagus is in season, run to the nearest supermarket or greengrocer and buy a big bunch. Cook it quickly and lightly. Stir-frying asparagus, rather than boiling it, preserves the water-soluble vitamins, including folate.
A cup of cooked asparagus provides remarkable amounts of folate – well over half the day's requirement. This heart-healthy B vitamin is also plentiful in peas. Folate helps to reduce blood levels of homocysteine, a substance linked to increased risk of cardiovascular disease.
