A new
BMJ opinion piece—by an author with egg and meat industry ties and who is concerned with “accelerated food trends towards plant-based diets/veganism”—is stirring up confusion about choline, an essential nutrient involved in memory, mood, muscle control, and other brain and nervous system functions. Don’t be confused: Eggs, meat, and other animal products are not the only sources of, nor the most healthful sources of, choline.
In fact, consuming dietary choline from animal products can actually lead to health problems.
The New England Journal of Medicine published a study looking at egg consumption and found that TMAO, a byproduct of dietary choline, can lead to greater risk for heart attack, stroke, and death. But the authors pointed out that a vegetarian or high-fiber diet can reduce choline intake and modulate the risk for heart disease.

Circulation also linked choline to increased risk of heart disease. But the authors found that participants who followed a vegan or vegetarian diet were protected against the harmful effects of choline.
