Folate is a crucial B vitamin, also known as B9, that plays a vital role in cell growth, DNA synthesis, and red blood cell production. Adequate intake is especially important during pregnancy and infancy for proper development, but it benefits everyone by helping to lower homocysteine levels, which is associated with a reduced risk of cardiovascular disease. For those looking to increase their dietary folate, nuts are an excellent and satisfying source. While many nuts contain this essential nutrient, certain types stand out for their exceptional folate content.
Nuts with the highest folate content
When searching for the top nuts for folate, peanuts often lead the pack, despite technically being a legume. They provide a significant boost of B9, along with a host of other beneficial vitamins and minerals. Hazelnuts and sunflower seeds are also excellent sources that offer a substantial amount of folate in a single serving.
Peanuts
- Folate Content: Peanuts are one of the most folate-rich options, providing a large percentage of the daily value in just one serving.
- Health Benefits: Beyond folate, peanuts are packed with protein, healthy fats, and antioxidants, making them a well-rounded and heart-healthy snack.
- How to Enjoy: Add raw or dry-roasted peanuts to trail mix, use them in stir-fries, or enjoy a tablespoon of natural peanut butter with an apple.
Hazelnuts
- Folate Content: Known for having a higher folate content than many other tree nuts, hazelnuts are a fantastic addition to any diet.
- Health Benefits: These nuts also contain high levels of vitamin E, which acts as a powerful antioxidant, and are a good source of dietary fiber.
- How to Enjoy: Sprinkle chopped hazelnuts over yogurt or salads, blend them into a nut butter, or simply eat them as a standalone snack.
Sunflower Seeds
- Folate Content: While not technically a nut, sunflower seeds are a folate powerhouse often categorized with nuts due to their nutrient profile. A one-quarter cup serving offers a significant portion of the daily recommended folate.
- Health Benefits: Sunflower seeds are also rich in vitamin E, selenium, and copper, all of which contribute to overall health.
- How to Enjoy: Add them to cereals, salads, or baked goods, or eat them raw for a crunchy and nutritious snack.
Other nuts and seeds with notable folate
While peanuts, hazelnuts, and sunflower seeds contain the highest concentrations, several other nuts and seeds also contribute to your daily folate intake. Incorporating a variety of these into your diet can help ensure you meet your nutritional needs.
- Walnuts: These are a good source of folate, with one ounce providing around 28 mcg, and they also offer beneficial omega-3 fatty acids.
- Pistachios: Besides being rich in antioxidants and B vitamins like B6, pistachios contain a moderate amount of folate.
- Flaxseeds: Just two tablespoons of these seeds can add a substantial amount of folate to your diet. They are also known for their fiber and omega-3 content.
- Almonds: Almonds are a good source of magnesium, calcium, and vitamin E, and they contain some folate as well.
- Chia Seeds: These versatile seeds offer a decent folate boost alongside their high fiber and omega-3 content.
How to incorporate more folate-rich nuts and seeds
Adding these nutrient-dense options to your meals is simple. Here are some ideas to help you get started:

Note: Folate is sensitive to heat, and some cooking methods can lead to a decrease in its content, but boiling and roasting are generally considered safe for retaining a large percentage.
What is the difference between folate and folic acid?
Folate is the form of vitamin B9 found naturally in foods like nuts and green leafy vegetables, while folic acid is the synthetic form used in fortified foods and dietary supplements. The body absorbs folic acid more readily than folate from natural sources.
Who needs to pay extra attention to their folate intake?
Pregnant women or those planning to become pregnant should be especially mindful of their folate intake, as adequate levels can help prevent neural tube birth defects in the fetus. Individuals with digestive disorders, certain genetic mutations, or those who consume excessive alcohol may also need to monitor their intake more closely.
How can I maximize the folate benefits from nuts?
To maximize the folate benefits from nuts, opt for raw or lightly roasted varieties. A study found that total folate retention in nuts and seeds after heating was, on average, 81%, indicating that heat processing can lead to some loss.
Do all nuts contain folate?
Most nuts and seeds contain some amount of folate, but the concentration varies widely between types. As seen in the table above, options like peanuts and sunflower seeds have significantly more folate per serving than others.
Can a folate deficiency cause health problems?
Yes, a folate deficiency can lead to several health issues, including megaloblastic anemia, where red blood cells are larger than normal. Symptoms can include fatigue, irritability, and shortness of breath. In severe, untreated cases, neurological damage can occur.
What are some easy ways to add folate-rich nuts to my meals?
Besides snacking, you can add folate-rich nuts to your diet by sprinkling them on salads or oatmeal, blending them into smoothies, or incorporating them into homemade trail mix. Using natural nut butter on toast or in sauces is another simple and delicious option.
Are there any risks associated with consuming high-folate nuts?
For most people, consuming folate from whole food sources like nuts is safe and beneficial. However, very high intake of synthetic folic acid from supplements can mask a vitamin B12 deficiency and may pose a risk for some individuals. A balanced diet with a variety of foods is key. If you have concerns, consult a healthcare professional.
