Improving the absorption of milk is actually very simple
It is 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 sticks to the stomach wall for better absorption.
The calcium in milk can also relieve stress, so it is more beneficial for the elderly's sleep. 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 blood calcium is supplemented and balanced throughout the night, so there is no need to dissolve calcium from bones, preventing bone loss and osteoporosis. Therefore, drinking milk before bedtime is good. Milk should not be drunk raw. When heated to boiling, the lactose in milk begins to caramelize at 100°C, decomposing into lactic acid and formic acid, reducing its nutritional value.
If milk is boiled for too long, 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 and in need of energy, drinking milk at this time will use the protein as a carbohydrate to be converted into heat energy and consumed. It stays in the stomach for a short time and is quickly excreted into the intestine, which is not conducive to digestion and absorption. It is not advisable to eat 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 which will coagulate into clumps, which are not easy to digest and absorb, destroying nutrients.
