There is no difference in nutrition between dumb eggs and ordinary eggs.

Sichuan Provincial Feed Work Station on different regions, different varieties, different breeding methods of dozens of batches of eggs for testing. The study showed that the unsaturated fatty acid content of the earth eggs is slightly higher than that of ordinary eggs, and the content of the rest of the nutrients are basically the same. This is due to the combination of food from free-range indigenous chickens or the extension of the breeding cycle, while the earth eggs with more fat will taste a bit more flavorful than ordinary eggs.

Wooden eggs, dumb eggs or walk-in eggs are all nicknames for free-range eggs. The Ministry of Agriculture's standards for eggs are only pollution-free, green and organic, and there is no exact standard for eggs.

It is not easy to identify whether the chickens that lay the eggs are free-range or caged, so there is no exact indicator to check whether an egg is recognized as a local egg. There's no way to determine if it's near industrial polluters, if it has parasites, etc. The environment and feed are difficult to control and may be even less safe.

Nutritional Value of Eggs

Protein: Eggs are rich in high-quality protein, each 100 grams of eggs contain 13 grams of protein, two eggs contain protein roughly equivalent to 50 grams of fish or lean meat protein. The digestibility of egg protein is also highest in milk, pork, beef and rice.

Fat: every 100 grams of eggs contain 11. 1 grams of fat, mostly concentrated in the yolk, to unsaturated fatty acids, fat is milky, easy to be absorbed by the body.

Cholesterol: egg yolk contains more cholesterol, per 100 grams can be as high as 1510 milligrams, but also rich in lecithin. After lecithin enters the bloodstream, it will make the cholesterol and fat particles smaller and keep them in suspension, thus preventing the deposition of cholesterol and fat in the blood vessel wall.

Scientists therefore believe that for older people with normal cholesterol, eating 2 eggs a day, with a maximum increase of 2 milligrams of cholesterol in 100 milliliters of blood, will not cause hardening of the blood vessels. However, should not eat more, eat too much, unfavorable digestion of the stomach and intestines, resulting in waste, but also increase the burden on the liver and kidneys.

Amino acids: eggs are particularly rich in methionine, while cereals and legumes are deficient in this essential amino acid.

Other micronutrients: eggs have other important micronutrients, such as potassium, sodium, magnesium, especially in the yolk of the iron up to 7 mg / 100 grams; eggs in the phosphorus is very rich, but the relative lack of calcium, so the milk and eggs **** with the consumption of nutritional complementarity. Eggs are also rich in vitamins A and B.
