　　Many people also add brown sugar when boiling eggs, thinking that brown sugar and eggs are very nutritious. If they are used together, they can be better than the other. However, if the heating time is too long, a chemical reaction will occur between the amino acids in the eggs and the sugar, forming a compound called glycosyl lysine. This substance is not only difficult to be absorbed by the human body, but also toxic. It can destroy the amino acid components in the eggs that are very beneficial to the human body, reduce the nutritional value of the eggs, and even cause damage to the human body. Therefore, eggs should not be cooked with sugar.
