Experts pointed out that eating milk and eggs for breakfast is unscientific, and it is difficult for protein to provide energy. At present, more than 9% of children only eat milk and eggs in the morning, and there is no food for breakfast for a long time, which is not good for children's growth and development.
Milk contains lactose, which is the dimer of galactose and glucose, and galactose is its nutrition. Eggs contain a lot of protein, which is decomposed into amino acids by protein. The absorption of amino acids consumes energy (active transport on the small intestine wall).
At this time, there is less glucose available in the blood, and galactose will be oxidized to provide energy. Some protein in eggs will react with some nutrients in milk, reducing the nutritional value, so it is not suitable for eating together.
Extended data:
Nutrition of milk:
Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese and molybdenum. The most rare thing is that milk is the best source of calcium for human body, and the ratio of calcium to phosphorus is very suitable, which is beneficial to the absorption of calcium. There are at least 100 complex species, and the main components are water, fat, phospholipids, protein, lactose and inorganic salts.
Nutrition of eggs:
According to the analysis, every100g of eggs contains12.8g of protein, mainly ovalbumin and ovalbumin, and contains 8 kinds of amino acids necessary for human body, which is very similar to the composition of human protein. The absorption rate of protein in eggs can reach 98%. Every100g of egg contains11~15g of fat, which is mainly concentrated in yolk and easily digested and absorbed by human body.
