The Importance of Choline: More Than Just a Nutrient
Choline is an essential nutrient, similar to B vitamins, that plays a critical role in several bodily functions. Your body synthesizes a small amount of it, but not enough to meet daily requirements, making dietary intake crucial. Choline is a precursor for acetylcholine, a neurotransmitter involved in memory, mood, and muscle control. It is also necessary for building cell membranes and for liver function, where it helps transport fats. A deficiency can lead to liver damage, muscle issues, and cognitive impairment.
The Unrivaled Champion: Beef Liver
When it comes to sheer choline concentration, beef liver sits at the top of the list. Just a 3-ounce (85 gram) serving of cooked beef liver contains an impressive 356 mg of choline, which accounts for approximately 65% of the Daily Value (DV). Its high nutrient density makes organ meat a powerhouse, also rich in other crucial vitamins and minerals such as iron, B12, and folate. While not a staple in all diets, incorporating beef liver or other organ meats like chicken liver (247 mg per 3 oz) can significantly boost choline intake.
Top Tier Sources: Eggs and Other Animal Products
Following beef liver, eggs are another superstar source of choline, and arguably one of the most accessible. One large hard-boiled egg provides 147 mg of choline, with almost all of the nutrient concentrated in the yolk. This makes whole eggs an excellent and versatile addition to any meal plan. Beyond eggs, other high-ranking animal products include:
- Fish: Many varieties of fish are excellent sources. A 3-ounce serving of cooked Atlantic cod contains 71 mg, while a half fillet of cooked salmon can provide over 160 mg. Fish also offer beneficial omega-3 fatty acids.
- Beef and Poultry: Lean cuts of beef and poultry also contribute to choline intake. For example, 3 ounces of beef top round can provide 117 mg, and a 3-ounce serving of roasted chicken breast offers 72 mg.
Plant-Based Powerhouses for Choline
For vegetarians and vegans, or those simply looking to diversify their diet, several plant-based foods offer substantial amounts of choline.
- Soybeans and Soy Products: Roasted soybeans are a top plant-based source, with a half-cup providing 107 mg of choline. Tofu and edamame are also great options.
- Shiitake Mushrooms: A plant-based alternative with a surprisingly high choline content, a cup of cooked shiitake mushrooms can provide 116 mg.
- Wheat Germ: This concentrated source of fiber and vitamin E also contains a significant amount of choline, with 1 ounce offering 51 mg.
- Cruciferous Vegetables: Vegetables like broccoli, cauliflower, and Brussels sprouts contain moderate levels of choline that can add up over the day.

Beyond the Highest Source: Optimizing Your Overall Choline Intake
While beef liver is the single highest source, the key to meeting your choline needs is a diverse diet. Relying solely on one food is not ideal; instead, it's about incorporating a variety of sources throughout your week. Consuming eggs for breakfast, a salad with grilled chicken or fish for lunch, and a dinner with beans or soybeans can help you easily reach your recommended daily intake. For many, a balanced diet including both animal and plant-based foods is the most practical strategy. For those following a strict vegan diet, it is especially important to focus on plant-based choline sources like soybeans, wheat germ, and certain vegetables, and potentially consider a supplement after consulting a healthcare provider.
Conclusion: Variety is Key to a Choline-Rich Diet
To ensure you're getting enough choline, the best strategy is to focus on dietary diversity rather than fixating on a single 'highest' food. While beef liver holds the top spot, a combination of accessible foods like eggs, fish, and plant-based options such as soybeans and wheat germ can provide ample amounts of this critical nutrient. Regular consumption of these varied sources will help support vital functions like brain health, liver function, and metabolism, safeguarding against deficiency. As always, for personalized advice, especially for pregnant women or individuals with specific health concerns, consulting a healthcare professional is recommended.
