Synopsis and Key Points:
Nutrition Today affirms that protein in eggs makes a valuable contribution to muscle strength sustained energy and promotes satiety.
Eggs provide affordable source of high-quality protein for sustained energy. New research shows high-quality protein in eggs contributes to power, strength and energy.
A research review published recently in Nutrition Today(1) affirms that the high-quality protein in eggs makes a valuable contribution to muscle strength, provides a source of sustained energy and promotes satiety. High-quality protein is an important nutrient for active individuals at all life stages, and while most Americans consume the recommended dietary allowance (RDA) for protein, additional research suggests that some Americans are not consuming enough high-quality protein to achieve and maintain optimal health.(2,3,4)
The Nutrition Today review analyzes more than 25 protein studies and concludes that the all-natural, high-quality protein in eggs contributes to strength, power and energy in the following ways:
The protein in eggs provides steady and sustained energy because it does not cause a surge in blood sugar or insulin levels, which can lead to a rebound effect or energy "crash" as levels drop. Eggs are a nutrient-rich source of high-quality protein and provide several B vitamins required for the production of energy in the body, such as thiamine, riboflavin, folate, B12 and B6.
Dietary protein intake directly influences muscle mass, strength and function in people of all ages. One egg provides more than six grams of high-quality protein (13 percent of the Daily Value), which can help individuals build and preserve muscle mass, and help older adults prevent muscle loss. Eggs are also rich in leucine, an essential amino acid that contributes to the muscle's ability to use energy and aids in post-exercise muscle recovery.
The high-quality protein in eggs provides all of the essential amino acids our bodies need to build and maintain muscle mass. In fact, the quality of egg protein is so high that scientists frequently use eggs as the standard for evaluating the protein quality of other foods.(5)
"While many Americans may be getting enough protein, they need to focus on consuming sources of higher-quality protein. Our review of the science suggests that eggs are an ideal protein choice, plus, they are very affordable," says Donald K. Layman, Ph.D., co-author of the research review and professor emeritus at the Department of Food Science and Human Nutrition at the University of Illinois. "In addition, individuals should focus on when they consume high-quality protein. Most protein consumption occurs in the evening, even though there are significant benefits to consuming more protein at breakfast, such as stimulation of muscle protein synthesis and long-lasting satiety."
Additional Benefits of Eggs' High-Quality Protein
The high-quality protein in eggs provides additional benefits, including:
Satiety & Weight Management:
A 2008 study showed that eating two eggs for breakfast helped overweight dieters lose 65 percent more weight and feel more energetic than those who ate a bagel breakfast of equal calories and volume.(6) Another recent study found that when individuals ate high-quality protein foods for breakfast, including eggs, they had a greater sense of fullness throughout the day compared to when they ate more protein at lunch or dinner.(7)
Value & Versatility:
In addition to providing high-quality protein, eggs are affordable and versatile. Serving for serving, eggs cost less than other sources of high-quality protein. For an average of just 15 cents per egg, Americans get a number of important nutrients in addition to high-quality protein, including choline, riboflavin and vitamin B12, all for only 70 calories per egg.

AEB is the U.S. egg producer's link to the consumer in communicating the value of The incredible edible egg and is funded from a national legislative checkoff on all egg production from companies with greater than 75,000 layers, in the continental United States. The board consists of 18 members and 18 alternates from all regions of the country who are appointed by the Secretary of Agriculture. The AEB staff carries out the programs under the board direction. AEB is located in Park Ridge, Ill.
The Egg Nutrition Center (ENC) is the health education and research center of the American Egg Board. Established in 1979, ENC provides science-based information to health promotion agencies, physicians, dietitians, nutritional scientists, media and consumers on issues related to egg nutrition and the role of eggs in the American diet. ENC is located in Washington, DC.
