The nutritional value of these two types of eggs is not very different, it is difficult to say which one is better. According to experts' initial comments and big data analysis, 20 rumors were shortlisted in the "Top 10 Science Gossip Ending List" of the "Dizhan 2018 China Science Popularization" campaign. Among them, the rumor that "earth eggs are more nutritious than ordinary eggs" has been widely circulated, also in the top 20 gossip list.

When it comes to local eggs, people always think they're better than chicken eggs. One explanation is that chickens eat different foods due to different feeding methods, and that the nutritional value of local eggs is different from that of ordinary eggs. Eggs from chickens raised in rural areas are not disturbed by humans and are not fed antibiotics and hormones. Eggs are pure and natural, rich in vitamins, high protein and fatty acids, and have high nutritional value. However, ordinary eggs produced by artificial farming are fed with specialized feed, which speeds up the growth and laying of chickens and greatly reduces nutrition. Is this really true? One study compared local (or free-range) and caged eggs. The results showed that the nutritional value of the two types of eggs is not really very different.

Professor Ma Guansheng of the Department of Nutrition and Food Hygiene at Peking University's School of Public ****Health said local chickens do get a more complete range of nutrients than those from chicken farms because of the different methods of rearing. However,from the nutritional composition of eggs, natural eggs contain higher levels of protein, carbohydrates, cholesterol, calcium, zinc, copper and manganese than ordinary eggs, and the cholesterol content in natural eggs is more than twice as high as that in ordinary eggs, which is related to the large proportion of yolk. However, fat, niacin, selenium, etc. Local eggs are lower than regular eggs. There is no difference in other nutrients.

This shows that the nutritional value of local eggs and ordinary eggs have their own advantages. People can choose according to their preference. Since earth eggs are also high in cholesterol, for those who need to limit their cholesterol intake, choosing regular eggs is usually fine.
