Milk replaces drinking water to destroy nutritional balance

It is said that milk can be used as water because almost 90% of the milk is water. Water is one of the most important nutrients for human life. When the human body loses more than 2% of water, the function of the body will be affected. The human body does not have water to supplement and can be life-threatening in a few days. Therefore, when the supply of water is insufficient, milk can of course be used as a source of water to supplement the body with precious water.

However, milk cannot be used as water. Because we can drink as much water as we can, milk cannot. The reason is that milk also contains many components such as fat, protein, sugar, calcium, and phosphorus, and their intake is limited. If the water we need every day comes from milk, nutrients such as fat may be taken too much. Therefore, milk cannot be consumed as water in an unlimited amount. "Highly nutritious" foods can't be better.

People who think that they can drink milk as a starting point think that milk is a highly nutritious drink. They think that since they are "highly nutritious," they should be more prosperous. Some people misunderstand "nutrition" and they interpret nutrition as the content and quality of various nutrients. Milk contains high levels of calcium, good protein quality, and contains more vitamin B2 and vitamin A, which are relatively inadequate to Chinese diets. But why is this misunderstanding?

First of all, nutrition refers to the reasonable combination of various foods in terms of quantity and variety to meet the needs of the human body. Due to the current limitation of nutrition in understanding, the rationality of this combination is usually expressed as the quantity and proportion of various nutrients, but this does not mean to put together nutrients such as protein, vitamins, calcium, iron, and zinc. Become "high nutrition". The proper nutrition of food should include a certain percentage of cereals, beans, vegetables, fruits, meat, eggs, milk and other foods, plus water, to form our daily meals. The use of large amounts of milk instead of water actually undermines the balance of this food mix.

Secondly, from the analysis of nutrients contained, milk contains about 3% of protein and fat, about 5% of sugar, and about one-thousandth of calcium. According to the recommendations of the Chinese residents' dietary guidelines, drinking water 1.2 liters a day, if the milk is used as water, calcium will be over-supply, fat and heat are also a little more. Saturated fatty acids in milk are detrimental to cardiovascular health. Too much energy can easily cause obesity. [Ten kinds of causes of obesity are the easiest ways to lose weight]. That is, using milk instead of one-half of a day's drinking water - 600 milliliters, and eating too much fat and calories. This is why Westerners choose skim milk for their health. As for the protein in milk, we don't really need to overemphasize it. Given the rich variety of food supplies and the relatively high proportion of animal foods, the protein supply of the urban population in China is not their main nutritional problem. For rural residents, especially for the economically backward rural residents, milk is more effective in improving protein nutrition.

The last thing to say is that high-protein, high-fat, high-energy diet has become one of the culprits of modern "civilized diseases" such as diabetes, cardiovascular and cerebrovascular diseases, and tumors. Therefore, some scholars hold very negative views about Westerners' eating habits of drinking milk and drinking milk as water. According to reports of some milk related to ovarian cancer and prostate cancer, some scholars have even advocated not drinking milk. This is somewhat extreme. The occurrence of cancer is related to many foods and dietary habits we eat daily, such as eating a lot of animal foods, fried and barbecued foods, smoked and preserved foods, excessive energy intake, and eating less fruits and vegetables. These issues are more related to cancer than milk. Therefore, we must not waste food, and we cannot simply understand these studies as the relationship between certain foods and tumors. It should be noted that any food is beneficial and harmful on both sides, moderate in quantity and harmful in excessive quantity, and the key is to mix it with a variety of foods.

Therefore, if we can drink some milk each day, we can improve the supply of calcium. When drinking water is inconvenient at hand, we can temporarily use it to supplement water. However, the long-term use of large amounts of milk instead of drinking water does not mean reasonable nutrition, and it is not high nutrition, and it may also bring about health hazards.
