Egg protein boosts power, strength and energy

Washington, Feb 17 (IANS) The presence of high-quality protein in eggs boosts 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. Additional research suggests that some Americans are not consuming enough of the stuff to achieve and maintain optimal health.

The review analyses more than 25 protein studies and concludes that the all-natural, high-quality protein in eggs contributes to strength, power and energy.

For instance, 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 thiamin, 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.

“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,” said Donald K. Layman, co-author of the research review and professor emeritus at the University of Illinois.

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.

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.
