Eggs are commonly used in making complementary foods. Many people think that the yolk of native eggs is redder and more nutritious to the human body. So what does it look like in fact? Let's have a look.
In fact, the nutritional value of native eggs is no different from that of ordinary eggs.
The yolk color of native chicken is more red, because native chicken intake a lot of beta carotene when eating feed. The size and price of an egg does not mean that it is "more nutritious", but only depends on the size of the hen itself and the production of eggs.
The nutritional value of eggs is almost the same. On the contrary, the eggs of ordinary chicken farms are more fresh and hygienic because of their large-scale, large output and fast turnover.
Unless there is a reliable source of native eggs, do not blindly buy native eggs. Native eggs are the products of individual workshops. The feed is not as nutritious as chicken farms, and the health status is unknown.
As for other eggs, such as goose eggs, duck eggs and quail eggs, their nutritional values are similar. From the perspective of cost performance, ordinary eggs are undoubtedly the best choice for mothers.
Native egg PK common egg
There is not much difference between native eggs and common eggs in nutritional composition, the difference of protein is less than 2%, and the calorie of native eggs may be slightly higher.
The difference between native eggs and common eggs
Because of the different feeding methods, the fat content of native eggs is slightly higher, but the unsaturated fatty acids and phospholipids which have the function of health preservation are slightly higher. However, the diet of common chicken was scientifically proportioned and dietary fiber was added, and the content of cholesterol and fat was slightly lower.
Therefore, although they have their own merits in nutritional composition, there is little difference between them.
Security differences
The growth, food and disease of native chicken, people can not understand its context, prone to food safety problems. The chicken farm eggs were fed and vaccinated intensively, and the food safety problems can be traced. Therefore, the safety of ordinary eggs may be higher.
Taste difference
Because the production cycle of native eggs is long, the water content is low, and the fat content is high, the real native eggs taste better than ordinary eggs. However, the production of native eggs is low and the price is high. The native eggs sold in the market are not real native eggs. The difference between the two can not be distinguished from the taste without prior warning.
Factors affecting eggshell color
Many people think that white eggs are native eggs, or brown eggs are more nutritious. And the fact is: the color of the eggshell depends on the breed of the hen, not on the nutritional content of the egg. In addition, diseases and seasonal changes of hens may also affect the color of eggshell, which has nothing to do with the feed they eat.
Factors affecting yolk color
Many people use the color of egg yolk to judge its nutritional value. In fact, the color of egg yolk is affected by chicken feed. Adding carotene, vitamin B2, lutein and other colored substances in feed will affect the color of egg yolk. It is not scientific to judge the nutrition of eggs by color.
