Folic acid, also known as folate, is a crucial B vitamin (B9) essential for cell growth, DNA formation, and red blood cell production. While leafy greens and legumes are common sources, nuts offer a convenient and tasty way to boost your folate levels. Certain nuts and seeds stand out for their particularly high concentration of this vital nutrient. Peanuts, which are technically legumes but are classified and consumed as nuts, are at the top of the list, followed by hazelnuts, walnuts, and some seeds. Incorporating these into your diet can support various bodily functions, from heart health to cognitive function.
The Top Nuts for Folic Acid Content
When searching for nuts rich in folate, you'll find that some are significantly more potent than others. Here are the leading contenders:
- Peanuts: Uncooked, raw peanuts provide the most significant amount of folate, with approximately 240 mcg per 100 grams. They are also rich in protein and antioxidants, making them a powerhouse snack.
- Hazelnuts (Filberts): These sweet, earthy nuts are another excellent source, offering about 113 mcg of folate per 100 grams. They also provide a good dose of vitamin E and manganese.
- Walnuts: Known for their omega-3 fatty acids, walnuts also contribute to your folate intake, with roughly 98 mcg per 100 grams. They are also high in antioxidants.
- Pistachios: Providing around 70 mcg of folate per 100 grams, pistachios are a great option for a savoury snack that offers a nutritional punch.
- Almonds: A popular choice for snacking and cooking, almonds contain about 44 mcg of folate per 100 grams, along with healthy fats, fiber, and vitamin E.
The Role of Seeds and Other Nuts
While the focus is often on nuts, many seeds also contain high levels of folate and are worth including in your diet. Sunflower seeds, for instance, are very high in folic acid, and incorporating seeds into your nut mix can further increase your nutrient intake. Other nuts, like cashews, contain lower amounts but still contribute to your daily value.

The Importance of Folic Acid and Where to Find It
Folic acid and its natural counterpart, folate, are vital for various bodily functions. It helps the body produce and maintain healthy new red blood cells. Folate is especially critical for women who are pregnant or planning to become pregnant, as it can help prevent certain birth defects of the baby's brain and spine. Beyond nuts, other excellent sources of folate include leafy greens, legumes, and fortified grain products.
The Difference Between Folate and Folic Acid
While the terms are often used interchangeably, there is a distinction. Folate is the naturally occurring form of Vitamin B9 found in foods, whereas folic acid is the synthetic, manufactured version added to supplements and fortified foods. The body absorbs folic acid more efficiently than folate from food sources, but both contribute to meeting your daily B9 needs. A balanced approach that includes natural food sources and potentially supplements is often recommended.
Conclusion: Making Informed Choices for a Healthier You
For those wondering which nuts have high folic acid, peanuts and hazelnuts stand out as some of the richest sources. Adding these, along with walnuts and other varieties, is an excellent way to supplement your diet with this essential vitamin. By focusing on whole, nutrient-dense foods, you can take a proactive step towards supporting your overall health and well-being. Always aim for a varied diet to ensure you are meeting all your nutritional needs, and consider discussing supplementation with a healthcare provider if you have specific health concerns or dietary restrictions.

Key Takeaways
- Peanuts are the Top Contender: Technically a legume, but nutritionally similar to nuts, peanuts provide the highest folate content per serving among common nuts.
- Hazelnuts and Walnuts are Rich Sources: Hazelnuts and walnuts are excellent options, offering substantial amounts of folate, vitamin E, and omega-3s.
- Seeds are Also Powerful: Don't overlook seeds like sunflower and flaxseeds, which also contain very high levels of folic acid and other nutrients.
- Vary Your Nut Consumption: A mix of different nuts and seeds can provide a broader range of nutrients beyond just folate, such as healthy fats and antioxidants.
- Preparation Matters: Opt for raw or lightly roasted, unsalted varieties to maximize nutrient content and avoid excessive sodium.
- Folic Acid vs. Folate: Remember that folate is the natural form in nuts, while folic acid is the synthetic form often added to supplements and fortified foods.
- Daily Intake Targets: Many organizations recommend 400 mcg of folic acid per day for adults, with increased amounts for pregnant women.
FAQs
Are peanuts truly a nut, and do they have a lot of folic acid?
Technically, peanuts are legumes, but they are nutritionally similar to tree nuts and are used in similar ways. They are one of the best sources of folic acid, with raw peanuts providing approximately 240 mcg per 100 grams.
What is the difference between folate in nuts and folic acid in supplements?
Folate is the natural form of vitamin B9 found in nuts and other foods. Folic acid is the synthetic form used in supplements and fortified foods. Folic acid is often more easily absorbed by the body.
How can I add more folate-rich nuts to my daily routine?
You can snack on a handful of peanuts or hazelnuts, sprinkle chopped walnuts or almonds over your morning oatmeal or salad, or add them to baked goods.
Do roasted nuts lose their folic acid content?
While some nutrients can be affected by heat, dry roasting has a minimal impact on the folate content of nuts. For example, roasted peanuts still contain a good amount of folic acid, though raw nuts often have slightly higher levels.
Are there any other high-folate seeds besides nuts?
Yes, sunflower seeds are exceptionally high in folic acid, with around 227 mcg per 100 grams. Flaxseeds and chia seeds are also good sources.
Can I get enough folic acid from nuts alone?
While nuts are a great source, it is important to eat a varied diet that includes other folate-rich foods like leafy greens, legumes, and fortified grains to meet your daily needs.
Is folic acid important only for pregnant women?
No, folic acid is crucial for everyone, as it is involved in DNA synthesis and cell division. However, it is especially critical for women who are pregnant or may become pregnant to prevent neural tube defects.
Are there any side effects to consuming too many nuts for folic acid?
Consuming nuts in moderation as part of a balanced diet is generally safe. Excessive intake may lead to high calorie consumption due to their dense caloric nature. High doses of synthetic folic acid supplements should be discussed with a doctor, though obtaining folate from whole foods is less likely to cause issues.
Can children eat nuts for folic acid?
Yes, nuts can be a healthy part of a child's diet for folic acid and other nutrients, provided there are no allergies. For young children, ensure nuts are prepared in a safe form (e.g., ground) to prevent choking.
What are some folate-rich breakfast ideas involving nuts?
Try topping your oatmeal or a smoothie bowl with walnuts, flaxseeds, and sunflower seeds. You can also mix chopped nuts into pancake batter or make a nut-based granola.
