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.

New USDA Analysis: Egg are 14% Lower in Cholesterol

There are many who think our food supply is unhealthy and getting more so. But, according to new United States Department of Agriculture (USDA) nutrition data, www.ars.usda.gov/nutrientdata many of our naturally produced foods are actually healthier than during our parent’s childhood. Beef and pork cuts are leaner, lower fat choices of milk and cheese are widely available and now the egg, already low in saturated fat, has been found to be lower in dietary cholesterol and qualifies as a good source of vitamin D. The USDA recently reviewed the nutrient composition of standard large eggs, and results show the average amount of cholesterol in one large egg is 185 mg, 14 percent lower than previously recorded.   The analysis also revealed that large eggs now contain 41 IU of Vitamin D, an increase of 64 percent.

This is wonderful news, since for a long time public health organizations have been continuing to advise people to restrict their dietary cholesterol based on old, less sophisticated research techniques than those used by scientists today. Unlike most countries around the globe who have looked at the science and decided that the evidence is lacking to continue to confuse people with guidance which restricts dietary cholesterol , the US continues to include a 300mg dietary cholesterol restriction in its dietary guidelines. The good news is that it is so much easier to include the many beneficial nutrients that an egg supplies in your diet daily without having to consider your dietary cholesterol intake. Unless of course, you often consume foods containing a great deal of solid fats and added sugar which unlike eggs and seafood that are naturally low in unhealthful fats and added sugars, can complicate your heart disease risk.  One look at the nutrition facts panel, and it’s easy to see why eating an egg daily is a healthy practice that our grandparents understood and valued.

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.
