8 Foods With Folate

Folic acid is the synthetic form of vitamin B9, which can be purchased as a supplement. Folic acid can also be found in some processed foods such as bread, cereal, and some brands of orange juice.

When naturally occurring, vitamin B9 is known as folate. Folate is found in many different types of fruits and dark green leafy vegetables.

If you're deficient in folate, you may experience symptoms such as muscle weakness, unexplained fatigue, and anemia.

What Are Folic Acid and Folate?

Folic acids and/or folate, also known as vitamin B9, are essential for your health. In fact, B9 is considered to be one of the body's 13 essential vitamins. B9 is necessary for the body to synthesize deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), the genetic makeup of all your cells.

Vitamin B9 can be consumed either naturally in foods (folate) or via supplementation (folic acid).

What Are the Health Benefits of Folate?

Adequate folate levels in our body are associated with some health benefits. Folate reduces the risk of the following:

List of Folate-Dense Foods

Folate can be found in a variety of vegetables, especially dark, leafy greens, fruits, and more. Foods fortified with folate (folic acid) are more easily absorbed in the body.

Asparagus

Asparagus has some of the highest levels of folate.Asparagus boasts 89 micrograms (mcg) of folate per four spears.

Asparagus is also high in vitamin K and antioxidants such as vitamin C. Asparagus has anti-inflammatory properties and helps the brain's development and functioning.

Legumes

Legumes are a family of foods that include beans, peas, and lentils. Legumes are an excellent source of folate. The folate content will vary based on the type of legume chosen. For example, pinto beans contain 294 micrograms of folate per one-cup serving, while blackeye peas contain 122 micrograms per one-cup serving (canned).

Legumes are also high in fiber and protein and are a great option if you're trying to cut back on your meat consumption.

Dark, Leafy Vegetables

Dark, leafy vegetables are a great source of folate. Some dark, leafy vegetables that are especially rich in folate include:

  • Spinach: 131 micrograms per 1/2-cup serving (cooked)
