Milk vs Water the body needs to replenish water. Milk is stronger than water 

Moisture is very important to the operation of our body functions. However, recent studies have found that in terms of "hydrating effect", plain boiled water is generally not the best, but milk takes the top spot. What is going on? Let us take you through today!  

A study suggesting milk may be more hydrating than water is getting attention recently. Researchers established a "beverage hydration index" based on how much people pee over four hours after drinking various beverages, and it turned out that milk has the best result when it comes to longer-term fluid retention. However, this does not mean milk is better than water, because water can still help you avoid dehydration in the first place.

To replenish water for a long time, drinking water may not be the best choice. A study by a British university pointed out that although plain water can quickly replenish water for the human body, beverages containing a small amount of sugar, fat or protein will retain water longer than water. "The most effective "water retention" beverage is milk.

First of all, let's emphasize that drinking water is still very important. Generally speaking, it is recommended that adults drink between 6 to 8 cups of water per day, which is about 1,500-2,000cc, which cannot be replaced by other beverages. As for the above-mentioned study, it was found that beverages with a little sugar, fat or protein can make the water stay in the stomach longer. The results of the study pointed out that because milk contains lactose, protein and fat, it can reduce the speed of water excretion from the stomach and make its "hydration effect" and "water retention effect" longer. 

Although beverages with a little sugar can keep the "water retention" effect sustained, too much sugar will backfire. The reason is that when these high-sugar beverages enter the small intestine, the body will transfer a large amount of water to the small intestine to dilute the high-concentration sugar. Therefore, the body can retain less water.

Coffee is the same. Drinking a small amount of coffee is no problem, but if you consume more than 300 mg of caffeine (about two to 4 cups of coffee), the diuretic effect of caffeine will accelerate the loss of water in the body.

On the other hand, the sodium contained in milk acts like a sponge to retain water in the body and reduce the amount of urine produced by the body. This effect is similar to that of the oral electrolyte solution used to treat diarrhea. The trace amounts of sugar, sodium and potassium in the solution can adequately retain water in the body.

Medical experts also pointed out that the physiological response of "thirst" is due to the increase in cell osmotic pressure, which stimulates the osmotic pressure receptors, triggers the excitement of the drinking water center, and initiates the feeling of thirst; after drinking water, the osmotic pressure will decrease, and this feeling is also It disappears naturally, but drinking milk does not. In other words, milk or other beverages cannot "quench thirst." In addition, the human kidneys and liver rely on water to remove toxins from the body, and water also plays an important role in maintaining skin elasticity and hydration. Therefore, in order to maintain health, you must drink more water anyway.
