Selenium rich eggs can supplement selenium and improve immunity, while astaxanthin eggs are rich in astaxanthin, which can resist oxidation, beautify and nourish the skin... These eggs, which are touted as beneficial by businesses, may have powerful functions, but they may not be suitable for everyone. How to rationally view the numerous "functional eggs" on the market and obtain nutrition safely and reliably? Let's take a look at the interpretation of experts in the field of food science. Eating eggs to supplement selenium is not reliable. Selenium is an essential trace element for humans and animals. Research has shown that selenium can eliminate free radicals present in the body and protect the normal function of cell membranes. In recent years, scientists have also discovered that selenium has functions such as anti-cancer, heart protection, cataracts prevention, and anti-aging. The selenium rich eggs on the market are usually produced by adding selenium containing yeast, organic selenium, etc. to the chicken feed during the feeding process of laying hens. By using healthy chicken bodies as a transformation "factory", the selenium in the chicken body is maintained in a dynamic balance during the egg laying cycle, and high selenium eggs containing selenium protein can be continuously produced. According to the GH/T1135-2017 standard for selenium rich agricultural products in China, the selenium content in eggs should be between 0.15-0.50mg (mg)/kg (kg), and the content of selenium substituted amino acids should be greater than 70%. Converted to commonly used selenium supplementation units, the selenium content of each hundred grams of selenium rich eggs should be 15-50 μ G (micrograms). Generally speaking, an egg weighing about 60 grams should have a selenium content of 9 to 30 micrograms. However, according to the testing results of relevant institutions publicly disclosed by the media in the past, some selenium rich eggs have a selenium content of only 13.8 μ G/100g, which is lower in selenium content than some ordinary eggs. Some selenium rich eggs have a selenium content of over 100 micrograms per hundred grams. According to the recommended selenium intake by the Chinese Nutrition Society, a normal adult's selenium intake should reach 60-250 micrograms per day, with 150 micrograms per day being the optimal. In addition to the natural intake of 10-20 micrograms of selenium from food and water, people should also supplement 130 micrograms of selenium daily. According to the standard that most selenium rich eggs contain an average of 21 micrograms of selenium per egg, it is unrealistic to consume an average of 6 selenium rich eggs per day to meet the selenium requirements for human supplementation. After all, most eggs have high cholesterol levels and are not suitable for large-scale consumption. In addition, although supplementing selenium appropriately is beneficial to the body, excessive supplementation may cause harm to the body, such as hair loss, nail deformation, rough hair, and even affect intelligence. Especially for infants and young children under 3 years old, frequent consumption of selenium rich eggs with selenium content exceeding 100 micrograms per hundred grams of eggs poses a health risk of excessive selenium supplementation. Astaxanthin eggs are not suitable for daily consumption. They are fed to laying hens through feed rich in fish, shrimp, and seaweed components, which can accumulate a large amount of astaxanthin in the eggs. Astaxanthin, with extremely strong antioxidant capacity, can reduce lipid peroxidation and effectively inhibit lipid peroxidation caused by free radicals. It is widely used in health products, medicine, cosmetics, etc. However, the biggest selling point of astaxanthin eggs is
