Spinach

Spinach is a popular leafy green vegetable that can be used in a variety of dishes such as soups, sauces, smoothies, and salads. One cup (30 grams) of raw spinach contains 181 percent of the daily value for vitamin K, 56 percent of the daily value for vitamin A, and 13 percent of the daily value for manganese.

It's also high in folate, which aids in the production of red blood cells and the prevention of neural tube defects during pregnancy. A low folate intake during the first trimester of pregnancy was found to be one of the most preventable risk factors for the neural tube defect spina bifida in one study. Consuming spinach, in addition to taking a prenatal vitamin, is an excellent way to increase your folate intake during pregnancy.
