Cardiometabolic Health

Cardiometabolic health is a relatively new term that encompasses cardiovascular and metabolic diseases, including type 2 diabetes and metabolic syndrome. Collectively, such conditions are the leading cause of preventable death worldwide. They all share similar risk factors (e.g., overweight/obesity, elevated blood pressure) which can be modified by diet and lifestyle choices. The available evidence indicates that eggs, when consumed as part of an overall healthy diet pattern, do not affect risk factors for cardiometabolic disease. Recent recommendations from the American Heart Association, American College of Cardiology and American Diabetes Association do not limit egg or cholesterol intake, a change from earlier guidance from these organizations. In fact, several global health organizations, including Health Canada, the Canadian Heart and Stroke Foundation, the Australian Heart Foundation and the Irish Heart Foundation, promote eggs as part of a heart-healthy diet.

Given the public health significance of understanding cardiometabolic diseases, research on risk reduction remains an active area of pursuit. For example:

  • A randomized controlled study in people with metabolic syndrome showed that those consuming three whole eggs per day as part of a reduced carbohydrate diet experienced favorable changes in HDL-cholesterol, insulin sensitivity, and other aspects of the lipoprotein lipid profile
  • A randomized controlled weight loss trial in people with diagnosed type 2 diabetes showed improved lipid and glucose markers following consumption of 2 eggs per day for 12 weeks.
  • An egg-based breakfast, rich in protein (35% energy; 26.1 g egg protein), promoted glycemic control in people with type 2 diabetes and pre-diabetes relative to a high-carbohydrate breakfast.

Breakfast is important; tips for making it nutritious

An article posted the other day in the Washington Post, Consumer Reports Insights: Breakfast is important; tips for making it nutritious, discusses the importance of the breakfast meal. With respect to eggs, the author states, “…having (eggs) at breakfast helps dieters lose weight … possibly because they’re so filling that they reduce the chance of overeating later. People with normal levels of LDL (bad) cholesterol who limit their intake of saturated fat can safely eat up to seven eggs a week; those with high LDL should limit themselves to four, or use egg whites or an egg substitute.” Recent research conducted at the University of Connecticut and Louisiana State University, among other places, supports the author’s contentions.

In addition, newer data from the University of Illinois indicates not only the importance of eating breakfast, but also the importance of consuming adequate protein during the breakfast meal to support muscle growth and repair. The typical American eating pattern consists of marginal protein intake at breakfast and lunch, with the largest amount of protein consumed doing the dinner meal. Researchers suggest that protein intake should be spread more evenly throughout the day, with similar quantities (some say as much as 30g per meal) consumed at breakfast, lunch, and dinner. Eggs are a great way to ensure optimal protein intake during the breakfast meal.
