The nutritional value of milk
Milk is easy to digest and absorb food, nutrient-rich, containing 3% to 4% of protein, and contains all of the body's essential amino acids. In addition, the absorption rate of milk protein in milk is very high, generally about 97%. Milk contains about 3.5% milk fat, which is a high-digestible food fat. When lactose contained in milk is digested and absorbed by the human body, it can be converted into one molecule of glucose and one molecule of galactose, and it can also promote the growth of beneficial lactic acid bacteria in the intestinal tract. The growth of lactic acid bacteria is beneficial to the elderly to absorb calcium and other minerals. Prevention of osteoporosis plays a positive role.
Milk contains many minerals, especially calcium and phosphorus. Milk contains many vitamins needed by the body. These vitamins play an important role in maintaining the health of the elderly, preventing and treating diseases, and promoting the absorption of calcium.
However, Xiao Bian reminded that although milk is rich in nutrition, it does not mean that there is no need for other ways to supplement nutrition, such as calcium supplementation. The amount of calcium absorbed by people through food every day is only about half of the human body's calcium requirement. For example, for adults, the daily requirement for calcium is 800 milligrams, while the daily calcium intake through food absorption is only 400 milligrams, which is why many people have appeared. Sub-health reasons. In addition to drinking milk and other food supplement methods, calcium supplements should be safe and effective. It is recommended that some marketers sell better products such as the body Henggeng calcium, using a unique calcium supplement formula, this product can be very old and children Good absorption, good calcium effect.
Soymilk and milk which have high nutritional value
Compared with milk, soymilk has similar protein content, but vitamin B2 is only 1/3 of that of cow's milk. The content of niacin, vitamin A and vitamin C in soymilk is zero. Although the iron content is high, it is not easily absorbed by human body. The calcium content is only half that of milk.
1 kcal of milk has 183 mg of cholesterol, soy milk does not contain cholesterol, and saturated fatty acids are also low. In other words, drinking soy milk is more conducive to preventing cardiovascular and cerebrovascular diseases than drinking milk. However, if soymilk is completely used instead of milk, calcium, vitamin A, vitamin D, vitamin B, vitamin C, and niacin and other nutrients required by the elderly will be reduced. In contrast, older people should still drink milk regularly.
However, milk also has a disadvantage that it contains a lot of lactose. Older people with chronic peptic ulcers, chronic enteritis, or gastrointestinal disorders are less tolerant to lactose. Drinking milk often causes diarrhea, so they should not drink milk, but should drink soy milk.
