1. Eggs help to improve performance
Eggs have a high satiety index, meaning they make you feel full for longer. One large egg supplies 6g of high quality protein and a large variety of essential nutrients, with the exception of vitamin C. This is why teaming up a fruit or orange juice with an egg and whole-wheat/low GI bread provides the perfect breakfast to perform well in a challenging environment.
2. Eggs can help to iron out problems
Many people with mild iron deficiency experience vague symptoms of tiredness, headaches and irritability. Iron is the carrier of oxygen in the blood and plays an important role in immunity, energy metabolism and many other functions in the body. The iron in egg yolk is in the form of heme iron, the most readily absorb-able and usable form of iron in food and more absorb-able than the form of iron in most supplements.
3. Eggs improve nutrient adequacy of the diet
The nutrient density of eggs makes them a valuable contributor to a nutritious diet. A study among egg vs. non-egg consumers revealed that the diets of the non-egg consumers were more likely to fall short of vitamins A, E and B12. Eggs contributed 10-20% of folate and 20-30% of vitamins A, E and B12 among egg consumers. This study demonstrates the important role one food can play in ensuring nutrient adequacy.
4. Eggs provide the best quality protein
Protein is one of the most important elements of our diet. Our bodies use protein to build new and repair old tissue. Eggs are champions at providing high quality protein. Amino acids are the building blocks of protein. Nine of these amino acids cannot be manufactured by the body and must be derived from the diet. A complete protein food contains enough of these nine essential amino acids to promote growth and maintain body tissue.
Egg, milk and meat (including poultry and fish) proteins are all complete proteins, but egg protein is of the highest quality, with a rating of 100. Compared to eggs, milk is rated at 93 and fish and beef at 75. One egg has approximately the same protein content as 30g cooked meat, fish or poultry. And apart from being the most versatile and best source of protein in our diet, it is also the least expensive.
