A pregnant woman should eat at least 2 eggs a day, ideally. While eggs are a superfood with many nutrients, this recommendation is based solely on the choline in eggs. Eggs and liver are the two highest sources of choline, and while other foods have choline, you'd have to overeat just to get close to the quantity found in eggs or liver. Eating 2 eggs a day gives you about half of the recommended daily intake for choline (250-300mg).
