25 folate-rich foods for pregnancy planning: portion tables and safe preparation
Compare 25 foods and 3 drinks in clear folate tables, with up-to-date pregnancy intake guidance, cooking ideas and practical food safety advice.
What folate does and why it matters
Folate is a name for several forms of vitamin B9 found in food. Folic acid is the form commonly added to supplements and fortified products. Vitamin B9 helps with cell division, DNA formation and red blood cell production; prolonged deficiency can contribute to a form of anemia.
A baby's neural tube forms very early, often before pregnancy is recognized. Taking the recommended folic acid before conception and in early pregnancy helps lower the chance of neural tube defects, though it cannot prevent every possible complication.
Folate intake before and during pregnancy
Japan's 2025 dietary reference values recommend 240 µg per day from the diet for adult women. The dietary recommendation rises by an additional 240 µg in the middle and late stages of pregnancy, for a total of about 480 µg per day. These refer to dietary folate, not an individual medication prescription.
People planning pregnancy or who may become pregnant are advised to obtain an additional 400 µg of folic acid daily through a supplement or fortified food, alongside varied meals, starting at least a month before conception. Medication use, certain conditions or a previous neural tube defect–affected pregnancy require an individualized discussion with a clinician.
Five standout folate-containing foods
Small amounts of toasted nori and natto can contribute folate to a meal. Animal liver is also extremely rich in folate, but it contains high amounts of preformed vitamin A; that makes liver products inappropriate as a pregnancy folate strategy. Raw sea urchin also carries food safety concerns.
The comparison below describes nutrient content, not a list of recommended pregnancy foods. Prefer safe vegetables, beans and appropriate folic acid supplementation rather than relying on liver or raw seafood.
| Food | Edible portion | Approx. folate | Practical note |
|---|---|---|---|
| Toasted nori seaweed | 3 g | 57 µg | Useful as a small rice or vegetable topping. |
| Natto fermented soybeans | 50 g | 60 µg | Eat freshly opened with rice; respect cold-chain and expiry instructions. |
| Raw sea urchin roe | 8 g | 29 µg | Raw seafood is a foodborne infection risk during pregnancy. |
| Chicken liver | 40 g | 520 µg | Very high in retinol; avoid liver and liver products during pregnancy. |
| Eel liver | 20 g | 76 µg | May be rich in retinol; not a suitable go-to folate source in pregnancy. |
Ten vegetables and legumes with folate
Leafy vegetables and legumes are flexible additions to everyday meals. Spinach, broccoli, komatsuna, asparagus and edamame provide folate as part of a wider nutrient mix.
The estimates below apply to the stated edible portion and preparation. Cooking times, seasonal variation and actual serving sizes mean the amount on your plate will not be identical every time.
| Food | Edible portion | Approx. folate | Practical note |
|---|---|---|---|
| Boiled spinach | 100 g | 110 µg | Steam or cook briefly and serve with a meal. |
| Cooked broccoli | 50 g | 60 µg | Cook until tender; soft stems are edible too. |
| Boiled edamame | 100 g | 260 µg | A protein-containing legume; cook thoroughly and avoid prolonged boiling. |
| Cooked asparagus | 60 g | 110 µg | Steam or sauté briefly. |
| Cooked sweetcorn | 220 g | 190 µg | Steaming or microwaving reduces nutrient loss to discarded cooking water. |
| Okra | 100 g | 110 µg | Cook gently, add to soup or steam. |
| Komatsuna greens | 100 g | 86 µg | Japanese leafy greens suited to soup or a quick stir-fry. |
| Cabbage | 100 g | 78 µg | Wash well, then use in soup or stir-fries. |
| Lettuce | 100 g | 73 µg | Wash thoroughly under running water before eating raw. |
| Bamboo shoots | 100 g | 63 µg | Prepare and cook thoroughly; refrigerate promptly. |
Five fruits that contribute folate
Fruit offers folate alongside water, fiber and other vitamins. Strawberries, mango, cherries, green kiwifruit and banana can be rotated across snacks and meals to keep your choices enjoyable.
A whole fruit can be much bigger than a standard sample portion, so compare weights rather than counting pieces alone. Wash fruit carefully and remove visibly spoiled areas before eating.
| Food | Edible portion | Approx. folate | Practical note |
|---|---|---|---|
| Strawberry | 15 g | 14 µg | Wash shortly before eating. |
| Mango | 300 g | 250 µg | Peel before eating; folate varies with variety and size. |
| Cherries | 50 g | 19 µg | Wash well and remove pits. |
| Green kiwifruit | 100 g | 36 µg | Adds vitamin C and variety. |
| Banana | 100 g | 26 µg | Convenient with pasteurized yogurt or a balanced snack. |
Five other foods with folate
Eggs, soy milk, small sardines, bread rolls and even potato chips contain some folate. Yet a food's overall nutritional value, preparation and hygiene matter at least as much as one vitamin measurement.
Cook fish and eggs fully, store soy milk as directed and check labels on fortified bread. Chips are not an ideal folate strategy because they often bring considerable salt and fat.
| Food | Edible portion | Approx. folate | Practical note |
|---|---|---|---|
| Fully cooked egg | 50 g | 22 µg | Cook thoroughly to reduce Salmonella risk. |
| Soy milk | 200 g | 62 µg | Choose properly stored pasteurized products. |
| Grilled small sardines | 50 g | 17 µg | Cook fully and watch salt in dried fish. |
| Soft bread roll | 100 g | 45 µg | Pair with vegetables and protein; read fortified-food labels. |
| Potato chips | 60 g | 42 µg | Often salty and fatty; not a preferred folate source. |
Three drinks that supply some folate
Certain fermented milk drinks are vitamin-fortified, while unsalted tomato juice and cow's milk naturally contribute varying quantities. Yakult Mil-Mil S has been advertised with folate content, but recipes and labels may change.
Do not rely on beverages alone to meet preconception needs. Compare current labels, consider added sugar and choose pasteurized dairy products.
| Food | Edible portion | Approx. folate | Practical note |
|---|---|---|---|
| Yakult Mil-Mil S drink | 100 g | 240 µg | Previously advertised as enriched; verify the current label. |
| Unsalted tomato juice | 200 g | 34 µg | Check brand-specific nutrition information. |
| Pasteurized cow's milk | 200 g | 10 µg | Also supplies calcium; avoid unpasteurized milk. |
Cooking and washing without unnecessary nutrient loss
Naturally occurring folate is water-soluble and some can leach into cooking water, especially with extended soaking or boiling. Steaming, quick cooking, or serving the broth as part of the meal can reduce losses. Still, washing produce properly must take priority over attempting to preserve every microgram.
Not every vegetable should be eaten raw. During pregnancy, food safety comes first: prepare legumes and bamboo shoots appropriately, wash fresh produce and vary preparations between soup, steamed vegetables and thoroughly cooked beans.
Food folate versus supplement folic acid
Natural food folates come in different chemical forms and are generally less consistently absorbed than synthetic folic acid. Folic acid is stable in supplements and fortified foods, and appropriate supplementation has evidence for lowering neural tube defect risk.
A diet containing leafy greens is important, but it does not necessarily replace the specific recommendation for 400 µg of folic acid each day before and during early pregnancy. Check for overlap between multivitamin products and ask for advice before using unusually high doses.
Supplement examples and reading the label
Japanese brands such as BELTA and Hagukumi have been marketed with different ingredient formulas and associated services. Labels such as 'organic', 'natural' or 'better absorbed' and promotional prices alone should not determine your choice; old prices and recipes may be out of date.
Check folic acid per daily dose, total tablet count, added nutrients, allergens, preformed vitamin A and label reliability. Anyone taking medication or managing a medical condition should discuss supplement changes with their clinician or pharmacist.
Food safety issues to consider in pregnancy
Avoid liver and liver products as a folate source during pregnancy because of potentially excessive preformed vitamin A (retinol). Avoid risky raw seafood, thoroughly cook meats, fish and eggs, skip unpasteurized dairy and take care with refrigerated ready-to-eat foods that can carry Listeria.
Monitor caffeine from coffee, tea and energy drinks according to pregnancy guidance. Ordinary culinary portions of parsley and celery do not warrant fear, but concentrated extracts and essential oils should not be taken as self-prescribed pregnancy remedies.
Freshness and storage of folate-containing foods
Folate can decline during prolonged storage and cooking. Refrigerate leafy greens appropriately, use them soon after purchase and wash before preparing. Correct freezing can be convenient when food cannot be used immediately.
Do not leave perishable items at room temperature for extended periods. Refrigerate prepared food promptly, reheat safely where appropriate and discard anything spoiled. Preventing foodborne illness matters as much as preserving vitamins.
A balanced day of folate-containing meals
Breakfast might include fully cooked eggs, bread and kiwi; lunch could feature rice, cooked edamame and steamed broccoli; dinner could combine well-cooked fish, spinach soup and a portion of fruit. These examples show variety rather than a required or restrictive meal plan.
Adapt meals to allergies, preference, medical needs and professional advice. The main message is to eat balanced meals, practice food safety and start the appropriate folic acid supplement when planning a pregnancy.
Numbers are approximate examples for the stated edible portion, not recommended daily servings. Cooking, brand, seasonal variation and database updates affect results. Boiled edamame is approximately 260 µg/100 g in the Japanese food composition database. High folate content alone does not mean pregnancy-safe.
