It's actually very simple to improve the absorption of milk.
It's best to drink milk at night because milk contains a biochemical substance called L-tryptophan that can induce drowsiness, as well as trace amounts of morphine-like substances. These substances have a certain sedative and hypnotic effect. Especially L-tryptophan, it is the main raw material for the brain to synthesize serotonin, which plays a key role in brain sleep. It can temporarily inhibit the brain's thinking activities, making people want to sleep, and it has no side effects. Moreover, milk adheres to the stomach wall, which is good for absorption.
The calcium in milk can also relieve tension, so it is more beneficial for the sleep of the elderly. Therefore, drinking milk at night is good for people's rest and sleep. Drinking milk before bedtime, the calcium in milk can be slowly absorbed by the blood, and the blood calcium is supplemented and maintained throughout the night, without the need to dissolve calcium from the bones, preventing bone loss and osteoporosis. Therefore, drinking milk before bedtime is good. Milk should not be consumed raw. When heated to boiling, take it out immediately. At 100°C, lactose in milk begins to caramelize and decompose into lactic acid and formic acid, reducing its nutritional value.
If milk is boiled for a long time, its color turns brown, its milky aroma decreases, the protein denatures and precipitates, and vitamins are also lost. The rotavirus antibody in milk, which has the effect of preventing infant diarrhea, is also destroyed. After boiling the milk and letting it cool slightly, do not add sugar. Lysine and fructose in milk form fructoselysine at high temperatures, which is harmful to the human body. Sugar is acidic, and the calcium in milk is alkaline. The combination of the two causes a large loss of calcium. It is best not to add sugar.
It is not advisable to drink milk on an empty stomach. When the body is in a hungry state, it needs energy. At this time, drinking milk will use protein as a carbohydrate to generate heat energy and consume it. It stays in the stomach for a short time and is quickly excreted into the intestines, which is not conducive to digestion and absorption. It should not be eaten with foods containing tannic acid and oxalic acid, such as strong tea, pomelo, lemon, bayberry, pomegranate, purslane, wild rice stem, spinach, etc. Because they contain a large amount of oxalic acid and tannic acid, they coagulate into lumps, which are not easy to digest and absorb, and destroy nutrients.
