Some people believe that eating raw eggs gives the best nutrition. Actually, there are many disadvantages to eating raw eggs, which can be harmful to health. Raw eggs contain anti-enzyme proteins and anti-biotin proteins. The former blocks the interaction between proteases in the human intestine and proteins, affecting protein digestion and absorption. The latter binds with biotin in food, forming substances that the body cannot absorb. However, these two harmful substances in raw eggs are destroyed when cooked, so they no longer affect nutrient absorption. The protein structure in raw eggs is dense, making it difficult for digestive enzymes in the gut to reach them, so they are not easily digested or absorbed. But when boiled, the protein structure becomes softer and easier to digest and absorb. About 10% of fresh eggs carry pathogenic bacteria, mold, or parasitic eggs. Some parents give their children a mixture of hot water and raw eggs with sugar, but because the pathogens and parasite eggs in the eggs are not fully killed, it can lead to diarrhea and parasitic diseases. If the egg contains Salmonella, it can cause food poisoning. Recently, it was discovered that eggshells may carry O-157 E. coli. Even if the amount is small, eating raw eggs can still cause food poisoning. Some people use raw eggs to treat constipation in children, but this doesn’t help with constipation and can spread toxoplasmosis, a zoonotic disease. This disease develops quickly and affects almost all organs due to Toxoplasma infection, and can even lead to death in severe cases. Therefore, eggs must be cooked thoroughly. Steamed eggs are best. Do not use hot water to mix eggs, and never eat raw eggs. Jin Weie, Tongji Medical College, Wuhan
