Dietary cholesterol increases the risk for type 2 diabetes, according to a meta-analysis published in Nutrition, Metabolism, & Cardiovascular Diseases. Those who consumed more cholesterol from foods like eggs and red meat increased their risk for diabetes more than those who consumed the least amount of cholesterol. For every 100 mg per day of added cholesterol—an egg has about 186 mg—the risk increased by 5%. Avoiding animal products, the only dietary source of cholesterol, is best for diabetes prevention.
