What is the primary food source of folic acid?

Folic acid, which is the synthetic form of folate, is crucial for various bodily functions, particularly in DNA synthesis and repair, as well as in the production of red blood cells. Among the food sources listed, leafy greens are recognized as one of the best natural sources of folate.

Foods such as spinach, kale, and romaine lettuce are particularly high in folate, making them important contributors to one's dietary intake of this essential nutrient. The high folate content in leafy greens is vital, especially for pregnant women, as it can help prevent neural tube defects in developing fetuses.

While citrus fruits and legumes also provide folate, their folate content is generally lower compared to that found in leafy greens. Supplements can provide folic acid as well, but they are not a food source. Therefore, when considering natural dietary options, leafy greens stand out as the primary food source of folic acid.
