Middle-aged and elderly people easily feel weak and osteoporosis. This is because in the middle-aged and elderly stage, the functions of body organs tend to deteriorate, and the absorption capacity and immunity will decline, which is easy to cause nutritional deficiency caused by osteoporosis and bone calcium loss. Many people will supplement calcium in various ways as soon as they pass middle age. In fact, low-priced milk is the best choice.
Milk is rich in various nutritional values.
Milk contains almost all kinds of nutrients needed by human beings. It is rich in protein, contains 8 kinds of essential amino acids, and also contains vitamins A, B, calcium, phosphorus, potassium, carbohydrates, linoleic acid and other components. A variety of immunoglobulins contained in milk can enhance human disease resistance, and lactose in carbohydrates can also regulate gastric acid, promote gastrointestinal peristalsis and digestive gland secretion, and inhibit the growth of spoilage bacteria.
Fresh milk is healthy milk.
Because a few enzymes in milk will decompose nutrients in milk, produce unpleasant smell and taste, and affect the quality of milk. Therefore, for safety and nutrition reasons, the extruded fresh milk must be processed. There are two kinds of processed milk: fresh milk and normal temperature milk. Fresh milk is sterilized by the advanced pasteurization method at present, and some beneficial bacteria are retained while removing harmful bacteria from milk, so that the freshness of milk is maintained to the greatest extent and the nutritional value of milk is not lost; Normal temperature milk adopts ultra-high temperature sterilization, which instantly kills all bacteria that may lead to deterioration, and also leads to the loss of certain nutritional value, but the shelf life is relatively long. Comparatively, fresh milk is more nutritious.
Keep milk fresh by blocking light.
Because the external light will change the flavor of milk and destroy the nutritional components of milk, proper packaging is also very important to protect the quality of fresh milk.
The common milk containers in the market are fresh house cartons, plastic bottles and glass bottles. Many customers only care about the convenience and beauty of the container when choosing milk, but don't consider the suitable packaging from the practical aspect. According to research, glass bottles can only isolate 9% of the light, translucent plastic containers can only isolate 30% of the light at most, while fresh house cartons can basically isolate 96% of the light, ensuring that the nutrients in milk are not destroyed and ensuring the quality of fresh milk. Moreover, the fresh milk carton is cheap and easy to carry, which is more in line with environmental protection requirements. They are the best milk containers.
