Folate, also known as vitamin B9, is a water-soluble vitamin that has many important functions in your body.

In particular, it supports healthy cell division and promotes proper fetal growth and development to reduce the risk of birth defects (1).

Folate is found naturally in many foods, as well as in the form of folic acid in fortified foods.

It’s recommended that healthy adults get at least 400 mcg of folate per day to prevent a deficiency (2).

Here are 15 healthy foods that are high in folate or folic acid.

Legumes are the fruit or seed of any plant in the Fabaceae family, including beans, peas and lentils.

Although the exact amount of folate in legumes can vary, they’re an excellent source of folate.

For example, one cup (177 grams) of cooked kidney beans contains 131 mcg of folate, or about 33% of the RDI (3).

Meanwhile, one cup (198 grams) of cooked lentils contains 358 mcg of folate, which is 90% of the RDI (4).

Adding eggs to your diet is a great way to boost your intake of several essential nutrients, including folate.

Just one large egg packs in 23.5 mcg of folate, or approximately 6% of the RDI (8).

Including even just a few servings of eggs in your diet each week is an easy way to boost your folate intake and help meet your needs.

Eggs are also loaded with protein, selenium, riboflavin and vitamin B12 (8).

Furthermore, they are high in lutein and zeaxanthin, two antioxidants that may help reduce the risk of eye disorders like macular degeneration (9, 10).

Summary Eggs are a good source of folate, with about 6% of the RDI in just one large egg.

Leafy green vegetables such as spinach, kale and arugula are low in calories yet bursting with many key vitamins and minerals, including folate.

One cup (30 grams) of raw spinach provides 58.2 mcg, or 15% of the RDI (11).

Leafy greens are also high in fiber and vitamins K and A and have been associated with a host of health benefits.

Studies show that eating more cruciferous vegetables, such as leafy greens, may be associated with reduced inflammation, a lower risk of cancer and increased weight loss (12, 13, 14).

A 3-ounce (85-gram) serving of cooked beef liver packs 212 mcg of folate, or about 54% of the RDI (30).

In addition to folate, a single serving of beef liver can meet and exceed your daily requirements for vitamin A, vitamin B12 and copper (30).

It’s also loaded with protein, providing a whopping 24 grams per 3-ounce (85-gram) serving.

Protein is necessary for tissue repair and the production of important enzymes and hormones.

Summary Beef liver is high in protein and folate, with about 54% of the RDI of folate in a single 3-ounce (85-gram) serving.

Wheat germ is the embryo of the wheat kernel.

Although it’s often removed during the milling process, it supplies a highly concentrated amount of vitamins, minerals and antioxidants.

Just one ounce (28 grams) of wheat germ provides 78.7 mcg of folate, which equals about 20% of your daily folate needs (31).

It also contains a good chunk of fiber, providing up to 16% of the fiber you need per day in a single ounce (28 grams) (31).

Fiber moves slowly through the GI tract, adding bulk to your stool to help promote regularity, prevent constipation and keep blood sugar levels steady (32, 33).

Summary Wheat germ is high in fiber, antioxidants and micronutrients. One ounce (28 grams) of wheat germ contains about 20% of the RDI for folate.

Besides being delicious and full of flavor, papaya is jam-packed with folate.

One cup (140 grams) of raw papaya contains 53 mcg of folate, which is equal to about 13% of the RDI (34).

Additionally, papaya is high in vitamin C, potassium and antioxidants like carotenoids (34).

Pregnant women should consider avoiding eating unripe papaya. Researchers speculate that eating high amounts might cause early contractions in pregnant women, but the evidence is weak (35).

Summary Papaya is rich in antioxidants and folate. One cup (140 grams) of raw papaya provides approximately 13% of the RDI for folate.

Summary Bananas contain a good amount of folate. One medium banana contains about 6% of the RDI.

Avocados are incredibly popular due to their creamy texture and buttery flavor.

In addition to their unique taste, avocados are an excellent source of many important nutrients, including folate.

One-half of a raw avocado contains 82 mcg of folate, or about 21% of what you need for the entire day (37).

Plus, avocados are rich in potassium and vitamins K, C and B6 (37).

They’re also high in heart-healthy monounsaturated fats, which may protect against heart disease (38).

Summary Avocados are high in heart-healthy fats and folate, with one-half of a raw avocado providing about 21% of the RDI for folate.

Many types of grains, such as bread and pasta, have been fortified to boost their folic acid content.

The amounts can vary between different products, but one cup (140 grams) of cooked spaghetti supplies approximately 102 mcg of folic acid, or 26% of the RDI (39).

Interestingly, some studies have demonstrated that the folic acid in fortified foods may be more easily absorbed than the folate found naturally in foods.

For example, one study concluded that the folate in foods such as fruits and vegetables is only about 78% as bioavailable as the folic acid in fortified foods (40).

Conversely, other research suggests that the specific enzyme used by the body to break down folic acid in fortified foods is not as efficient, which can result in a build-up of unmetabolized folic acid (41).

A well-balanced diet that’s rich in natural sources of folate with moderate amounts of fortified foods can ensure you’re meeting your needs, all while minimizing potential health concerns.

Summary Fortified grains contain added amounts of folic acid. One cup (140 grams) of cooked spaghetti contains about 26% of the RDI.

Folate is an important micronutrient found in abundance throughout your diet.

Eating a variety of healthy foods, such as fruits, vegetables, nuts and seeds, as well as fortified foods, is an easy way to increase your folate intake.

Not only are these foods rich in folate, but they are also high in other key nutrients that can improve other aspects of your health.
