Why all athletes and bodybuilders eat chicken eggs ?

 Introduction:

Eggs are a great source of protein. This is not up for debate. Eggs have long been recognized and appreciated as a great source of high quality protein, both to the average Joe and those who spend lots of time with the iron in the gym.
Just one egg can supply over 12 percent of the daily recommended intake of protein. The quality of egg protein is so high that the World Health Organization (WHO) uses it as a reference standard against which the protein quality of all other food is judged. Egg protein is a complete protein and thus includes a number of amino acids such as leucine, isoleucine, valine, methionine, cysteine, lysine, tryptophan, and other essential amino acids that contribute to the repair and regeneration of muscle
Here are 7 reasons why bodybuilders and athletes eat egg;

1. CLA-Conjugated linoleic acid:
   CLA is derived from animal sources. Chickens fed their natural diet and raised organically produce eggs with higher levels of CLA. CLA has been found to have antitumor activity at levels achievable through your diet. In other animal studies, CLA has been shown to help with regulation of glucose and to decrease the percentage of body fat. CLA is found in the yolk of the egg.
2. Heart-Healthy Cholesterol:
   Years ago, the egg was demonized because of its cholesterol content, which is also located in the egg yolk. However, in most circumstances, dietary cholesterol has little to no impact on blood cholesterol levels—one of the reasons cholesterol-lowering drugs are such a big business. Many studies have demonstrated that the consumption of several eggs per week has no significant impact on blood cholesterol levels, stroke, or heart disease. Some studies, where the cholesterol did increase, found it was the HDL or “good” cholesterol that was on the rise. The data has been so compelling that the American Heart Association was forced to retract its recommended ban on the consumption of eggs and, in fact, today considers their inclusion part of a healthful, balanced diet.
3. Super Fats:
   Omega-3 fatty acids include the essential fatty acid ALA, or alpha linolenic acid, and the conditionally essential fatty acid DHA, or docosahexaenoic acid. These polyunsaturated fatty acids are critical in helping the body reduce levels of inflammation. They are also critical in the maintenance of heart and brain health. Some egg brands achieve high levels of omega-3 fatty acids by supplementing the chickens’ diet with non-naturally occurring supplements such as menhaden oil, krill oil, flaxseed oil, and algae oil. However, when chickens are allowed to pasture they tend to consume legumes that result in eggs that are naturally high in omega-3 polyunsaturated fatty acids, and nothing beats a natural high. Additionally, DHA has been shown to turn on genes that increase fat burning while deactivating genes that increase fat storage.
4.    Source of Protein:Eggs contain about 6 grams of high quality protein, so high that it is used as the standard by which other foods are measured. Eggs are also a rich source of vitamins, including A, E and K and a range of B vitamins such as B12 (energy), riboflavin and folic acid. Eggs also contain all eight essential amino acids needed for optimal muscle recovery and building valuable minerals like calcium, zinc and iron.
5.       Calories:
   Bodybuilders want to stay lean, and so they need to control their overall calorie consumption while still getting lots of protein. Eating the whole egg gives you a bit more protein and a lot more calories — twice the protein but more than four times the calories. 300kcal of egg whites would give you 65g of protein, while 300kcal of whole eggs only gives around 25g protein.
6.      Antioxidants:
   The egg is a powerhouse of disease-fighting nutrients like lutein and zeaxanthin. These carotenoids may reduce the risk of age-related macular degeneration, the leading cause of blindness in older adults. And brain development and memory may be enhanced by the choline content of eggs..But the full health benefits of eggs can only be realized if you store them properly — in the refrigerator — and cook them thoroughly to kill any potential bacteria.
7. B vitamins:
   Eggs provide vitamin B2, or riboflavin, and vitamin B12, or Cobalamin. One large egg provides 0.25 mg of riboflavin, meeting 15 percent of the recommended daily value for this nutrient as well as 0.6 mcg of vitamin B12, or nearly 10 percent of the recommended daily value. Riboflavin, like other B vitamins, plays a role in energy metabolism, or breaking down the foods you eat into energy your cells can use. Vitamin B12, found almost solely in animal foods, helps you make genetic material, or DNA, as well as red blood cells. All of the B vitamins are important for promoting a healthy nervous system.
