Many people have the habit of drinking a glass of milk for breakfast and before bed, and they are used to drinking a large glass of milk in one go. Is this way of drinking milk affect the absorption of nutrients? Experts say that drinking milk should be slow, not "gulped down".
Don't just focus on speed when drinking milk
When eating, people emphasize "chewing slowly", and the same goes for drinking milk. Drinking too fast will put a certain burden on the gastrointestinal tract. Lactase cannot reach the required level in the body in a very short time, causing stress-induced lactose intolerance, which may lead to diarrhea, and the digestive absorption rate will also be affected. This means that people who don't like milk may waste nutrients by forcing themselves to drink it in one gulp just for its nutritional value.
Experts point out that although some people are used to a fast-paced lifestyle of eating and drinking quickly, and their gastrointestinal tolerance is strong, so they may not feel uncomfortable even if they drink milk in large gulps, from a long-term health perspective, milk should also be sipped slowly. It is not recommended to gulp down a large glass or bottle at once.
Pay attention to the temperature when adding sugar
It is a common belief among many parents that unsweetened milk is not good for children's digestion. However, experts say that adding sugar is to increase the calories supplied by carbohydrates, but it must be quantified, generally 5 to 8 grams of sugar per 100 ml of milk. If too much sugar is added, it is more harmful than beneficial for the growth and development of infants and young children. Excess sugar entering a baby's body will cause water retention, making muscles and subcutaneous tissues soft and weak. Such babies may look chubby, but their body's resistance is poor, which is medically called "mud-paste" physique. Excess sugar stored in the body can also become a risk factor for some diseases, such as dental caries, myopia, and arteriosclerosis.
At the same time, it is best to add sucrose to milk. After sucrose enters the digestive tract, it is broken down by digestive fluids into glucose, which is absorbed by the human body. Some parents specially buy glucose for their children, which is completely unnecessary. Because glucose has a low sweetness, using too much of it can easily exceed the specified range, and children may refuse to eat it because it's not sweet enough.
So when should sugar be added? Some parents add sugar to milk and heat them together. This way, lysine in the milk will react with sugar at high temperatures (80℃-100℃) to produce a harmful substance, glycosylated lysine. This substance is not only not absorbed by the body but is also harmful to health, especially for children. Therefore, the boiled milk should first be cooled to warm (40℃-50℃) before adding sugar to dissolve it.
