Eggs carry bacteria during their formation. Immature eggs can't kill bacteria and easily cause diarrhea. Protein in eggs contains avidin, which will affect the absorption of biotin in food and cause symptoms such as loss of appetite, general weakness, muscle pain, skin inflammation and eyebrow removal. Eggs contain antitrypsin, which affects the digestion and absorption of protein. These two substances can not be decomposed in immature eggs, thus affecting protein's digestion and absorption.
