Choline is an essential vitamin-like nutrient required for cell membrane phospholipids, lipid transport out of the liver, methylation reactions and synthesis of the neurotransmitter acetylcholine.
Because dietary surveys show that most adults consume less than the recommended Adequate Intake—and because animal foods like egg yolks are the most concentrated single sources—vegetarian and vegan cooks benefit from knowing which plant and dairy staples contribute choline across the day.
Adult choline targets: Adequate Intakes (AI) and the 550 mg Daily Value
Even though the human liver can synthesize small amounts of choline, internal production is not enough to meet physiological needs, which is why the U.S. National Academies classify choline as an essential nutrient. According to Oregon State University's Linus Pauling Institute, severe choline deficiency causes abnormal fat accumulation in the liver (nonalcoholic fatty liver) and muscle damage.
The Food and Nutrition Board sets the adult Adequate Intake (AI) for choline by sex and life stage, while the U.S. Food and Drug Administration (FDA) uses 550 mg/day as the single reference Daily Value (DV) on Nutrition Facts and Supplement Facts panels:
- Adult women (19 years and older): 425 mg/day Adequate Intake (increasing to 450 mg/day during pregnancy and 550 mg/day during lactation).
- Adult men (19 years and older): 550 mg/day Adequate Intake.
- FDA Nutrition Facts Daily Value (DV): 550 mg/day (voluntary on retail food labels unless added or claimed).
How eggs, dairy, cruciferous vegetables, soy and peanuts supply choline
According to NHANES data cited by the Linus Pauling Institute, mean U.S. choline intakes are about 284 mg/day for women and 390 mg/day for men, and vegetarians—especially vegans who consume no eggs or milk—can be at risk for low choline intake if meals rely heavily on refined foods.
As the Linus Pauling Institute notes, eggs (where the choline is concentrated in the yolk), dairy products, cruciferous vegetables (such as broccoli, Brussels sprouts, cauliflower and cabbage), soybeans/tofu, peanuts, legumes and whole grains are key dietary contributors:
- Lacto-ovo vegetarian kitchens: Egg yolks are by far the richest single vegetarian source of choline, while milk and yogurt contribute steady amounts across daily servings.
- Plant-based and vegan kitchens: Soy foods (soybeans, tofu, soy milk), peanuts and peanut butter, cruciferous vegetables (broccoli, Brussels sprouts, cauliflower), beans, lentils, quinoa and wheat germ combine across meals to build daily choline intake.
- Dietary betaine sources: The Linus Pauling Institute also notes that spinach, beets and whole wheat are rich in betaine (a choline metabolite); while betaine cannot be converted back into choline for cell membranes, it can spare some of the body's methyl-donor requirement for choline.
How to combine plant and dairy choline sources in everyday meals
Because no single plant food matches the choline concentration of an egg yolk, plant-based cooks meet their daily choline target by layering multiple medium-source foods across breakfast, lunch and dinner:
- Include soy or legumes daily: Use tofu, tempeh, edamame, chickpeas or lentils as your main meal protein.
- Pair meals with cruciferous vegetables: Roast or steam broccoli, cauliflower, Brussels sprouts or cabbage as a regular side dish.
- Use peanuts, seeds, whole wheat, spinach and dairy (or fortified soy milk) to round out daily intake.
