Recent study shows that eating two eggs for breakfast, as part of a calorie-restricted diet, helps overweight adults lose more weight and have greater reduction in BMI, waist circumference and percent body fat than those who ate a bagel breakfast of equal calories1. Further, total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides, did not differ between the groups. This study supports previous research which showed that people had greater feeling of satiety after the egg breakfast, and consumed significantly less energy for the entire day as well as for the next 36 hours2.
Is an Egg a Day Okay? Does It Cause High Cholesterol?
Eggs are very nutritious. They are an excellent source of protein and contain omega-3 fats, as well as 11 different vitamins, minerals and antioxidants. The common belief that eggs cause high cholesterol is untrue. A large study shows that there is no evidence for a relationship between dietary cholesterol or eggs and heart disease risk3. Its findings suggest that consumption of up to one egg a day is unlikely to have significant overall impact on the risk of coronary heart disease or stroke among healthy men and women. However, for people with high cholesterol or heart disease, the American Heart Association recommends that they should not consume an egg a day. More precisely, it recommends these people should eat less than 200mg of cholesterol a day4. On a weekly basis, it recommends that they should limit their intake to no more than three yolks, considering that each egg yolk contains approximately 213mg of cholesterol.
Researchers also found that consumption of one or more eggs per day was associated with an increased risk of coronary heart disease in people with diabetes5. There was also evidence that daily egg consumption would significantly increase the risk of Type 2 diabetes6 and common diabetic complications in people with existing diabetes7. Hence, people with diabetes or those at risk should not consume an egg a day.
