What are the effects of drinking milk on an empty stomach?

Milk is not only protein, but also carbohydrates, and the body preferentially absorbs carbohydrates from milk for energy, followed by fat in milk, and protein is only in third place. The crux of the matter is that the body automatically breaks down fat and muscle proteins to provide energy on an empty stomach.

At this time, instead of worrying about losing that little bit of protein absorption by drinking milk on an empty stomach, it is better to grab a milk pad to cushion your stomach and protect your muscles. ‍‍

Nutrients are mainly absorbed in the duodenum and upper jejunum; Liquid foods stay in the gastrointestinal tract for a shorter period of time. Therefore, if you drink milk on an empty stomach, it will run to the lower intestines before it has time to absorb well, which is called poor absorption.

People with sensitive gastrointestinal tract (mostly frail girls), in medical terms, people with "irritable bowel syndrome", pour cold milk into the stomach, even if they are not lactose intolerant, they may have diarrhea due to irritability. You can drink it slowly in small sips or warm it with warm water. Anyway, I think it's better not to drink milk on an empty stomach, but if you like to drink it on an empty stomach, it's okay, just be happy.

Milk contains nutrients such as protein, lactose, fat, etc. Lactose belongs to carbohydrates and substances, he will give priority to ** to the human body part of the energy to save protein, the so-called "empty stomach milk nutrition can not be fully absorbed" probably refers to the loss of protein, in fact, will not cause this situation. However, some people with gastrointestinal function or congenital "lactose intolerance" should not drink milk on an empty stomach, especially not to drink a large amount of milk on an empty stomach.

For example, some people will have bloating and diarrhea after drinking milk on an empty stomach, and such people are not suitable for drinking milk on an empty stomach. There are also people who rarely drink milk since the baby is weaned, and such people are not suitable for drinking milk on an empty stomach, because there will be "lactose intolerance", and there will also be bloating, diarrhea, and indigestion. Therefore, if you drink milk regularly since you were a child and your gastrointestinal function is good, drinking milk on an empty stomach will not cause any discomfort or harm.

Milk contains a lot of lactose. The average Chinese lack lactase and cannot break down lactose. After drinking milk on an empty stomach, lactose stays in the intestines for a long time, causing osmotic pressure to rise.

The increase in osmotic pressure can cause the intestines to be unable to absorb water from the intestines. Therefore, a large amount of water will accumulate in the large intestine, and it will be diarrhea. If there is already some stool left in the large intestine, then the milk will only dilute the stool when it enters the large intestine and will not flow in the large intestine, so the diarrhea symptoms are milder than drinking milk on an empty stomach.

But even if you don't have diarrhea by drinking milk when you have poop, bacterial fermented lactose can still cause bloating and farting.

Drinking milk on an empty stomach will not only make people drowsy, but also cause a great waste of various rich nutrients in milk. Because the protein in milk will be excreted from the stomach quickly, and the precious protein will be broken down by the body and consumed as calories, so it is difficult to play its proper role. The amino acids in milk are excreted into the large intestine without time to be absorbed in the small intestine, and even some harmful substances will be produced.

What are the dangers of drinking milk on an empty stomach? First, it is not easy to digest and easy to release gastric acid, second, it affects the health of the intestines and intestines, and third, nutrients are not easy to absorb, so it is recommended to drink milk after breakfast and before going to bed.

There is no harm.

Some people say that drinking milk on an empty stomach will consume protein as energy in vain, but in fact, milk contains about lactose, which will give priority to decomposing energy supply and saving protein; In addition, milk also contains about 3% fat, which can also play a role in energy. Therefore, drinking milk on an empty stomach does not cause protein to be wasted.

Babies under the age of 1 can drink milk on an empty stomach, which proves that the nutrients in milk are very comprehensive and can be fully utilized by the human body. Even with a slight decrease in digestibility, it is better to drink milk on an empty stomach than nothing at all, when it is too late to eat breakfast.

If you have bloating and diarrhea after drinking milk, it means that you should not drink too much milk on an empty stomach, and you should eat some starchy foods and then drink them in small sips, or you can change to yogurt.
