Eggs are the food we need for our daily lives, and we often eat, but also very rich in nutritional value, often as essential supplements for morning nutrition. Then below the livestock and poultry producers in Hubei tell you that the nutritional value of eggs is reflected in where?
It is understood that eggs per hectogram contains 12.8 grams of protein, mainly ovalbumin and oocyst, which contains the body's eight essential amino acids, and very similar to the composition of human protein, the body's absorption of egg protein up to 98% . Egg contains 11 to 15 grams of fat, mainly concentrated in the egg yolk, but also easily digested and absorbed by the human body, egg yolk is rich in lecithin, sterols, lecithin and calcium, phosphorus, iron, vitamin A, vitamins D and B vitamins. These ingredients are very helpful to improve the function of the nervous system, therefore, the egg is better brain food.
An egg contains as much calories as half an apple or half a cup of milk, but it also owns 8% phosphorus, 4% zinc, 4% iron, 12.6% protein, 6% vitamin D , 3% Vitamin E, 6% Vitamin A, 2% Vitamin B, 5% Vitamin B2, 4% Vitamin B6. These nutrients are essential to the human body and they play an extremely important role, such as repairing human tissues, forming new tissues, consuming energy and participating in complex metabolic processes.
【Protein】: Eggs are rich in high-quality protein containing 13 grams of protein per 100 grams of eggs. The two eggs contain roughly 50 grams of protein, either fish or lean protein. The digestibility of egg protein is also highest in milk, pork, beef and rice.
[Fat]: Each 100 grams of eggs containing 11.1 grams of fat, mostly concentrated in the egg yolk to unsaturated fatty acids, fat was milky, easily absorbed by the body.
Cholesterol egg yellow contains more cholesterol, up to 510 mg per hundred grams, therefore, many people, especially the elderly are wary of eating eggs, afraid to eat eggs caused by increased cholesterol and lead to atherosclerosis. Scientists have found that although eggs contain more cholesterol, but also rich in lecithin. When lecithin enters the bloodstream, it causes small particles of cholesterol and fat to stay in suspension, thereby preventing the deposition of cholesterol and fat on the blood vessel wall. Therefore, scientists believe that eating two eggs a day for normal cholesterol-fed seniors increases cholesterol by up to 2 milligrams in 100 milliliters of blood without causing hardening of the arteries. But should not eat too much, too much to eat, adverse gastrointestinal digestion, resulting in waste, but also increase the burden of liver and kidney.
[Amino acids]: Egg is particularly rich in methionine, while cereals and beans lack the amino acids essential for the body.
Other micronutrients: There are other important micronutrients in eggs such as potassium, sodium and magnesium, especially iron in yolk, up to 7 mg / 100 g, but the iron in the yolk is non-heme iron, Combined with the existence of utilization is only 3%; the phosphorus in the egg is very rich, but the relative lack of calcium, so the milk and eggs can be nutritionally complementary to each other. Egg, vitamin A, B is also very rich.
So, usually can eat more eggs, good for the body. It is best to eat two eggs a day is better.
