You may not know that eggs can't be cooked with sugar, and it's not good to eat sugar after eating eggs. Many places have the habit of eating poached eggs in sugar water, which will make the amino acids in the protein of eggs form a combination of fructosyl lysine, which is not easily absorbed by the human body.

similarly, eggs should not be eaten with soybean milk. Many mothers will add plumeria in soy milk, or let their children drink soy milk after eating eggs. Soybean milk contains a substance called trypsin, which combines with ovalbumin in egg white, which will cause the loss of nutrients and reduce the nutritional value of both.
