Only with the non-nitrogen calorie burning of the proteins in milk and eggs can the body better synthesize receptor tissues, muscles, immunoglobulins and improve the immunity of the body. Without the most basic calories, only a bottle of milk and an egg, its rich protein will first be used as fuel to break down to provide energy for the body, so a bottle of milk and an egg in the morning is not allowed.
