Black eyed peas
Although not especially rich in vitamins, black-eyed peas do contain a substantial amount of folate. From your 1/2-cup serving of cooked black-eyed peas, you can get 179 mcg folate, which is almost half the daily amount you need of this nutrient. Folate, which helps with cell formation, is especially important during pregnancy.
Black-eyed peas are a modest source of potassium. A 1/2-cup serving provides 239 mg of this mineral, or almost 12 percent of the recommended daily intake. Potassium is critical for keeping the muscles, including the heart, working properly. The same serving of black-eyed peas also contains 2.2 mg of iron or about 12 percent of the recommended daily intake.
