It shows a 6 percent increased risk of heart disease when the number of eggs a person ate each day increased by half an egg. Norrina Allen, an associate professor at Northwestern University said that, in the United States, eggs are generally one of the top sources of cholesterol(胆固醇) in a person's daily food.
