For example, some people say that among brothers and sisters, the elderly who have the habit of drinking milk will live longer;
Some people say that it is useless to drink milk often, and some people drink milk often, which is not necessarily healthier and longer.
Others say that drinking milk is more likely to cause cardiovascular diseases. If you want to supplement nutrition, you can eat other things to supplement it. There is no need to drink milk. ...
In fact, Dr. Lepu can tell you directly that milk has long been recommended as a daily nutritional source by the Dietary Guide for China Residents, but many people in China are still not used to drinking milk and do not pay enough attention to its nutritional value. The nutrition and health care function of milk is irreplaceable by other foods.
First, milk lowers blood sugar and stabilizes blood pressure.
The two most outstanding advantages of milk are its rich calcium content and rich protein.
Milk is considered as an important source of calcium and protein. Among them, calcium is an important element of bone health and also affects the health of teeth. Old people are most prone to calcium deficiency, fracture and bad teeth. It is very necessary to drink milk every day.
Protein nutrition in milk can not be ignored.
Protein in milk is a "complete protein" containing all essential amino acids, that is, high-quality protein. It mainly includes casein, whey protein and lactoglobulin.
Among them, the nutritional value of whey protein is the highest among all protein. Whey protein is not only rich in essential amino acids, but also easier to digest and absorb. Especially whey proteins represented by lactoferrin, lactoperoxidase, α -lactalbumin and β -lactoglobulin have smaller molecules and higher digestion and absorption efficiency.
High quality protein in milk is very friendly to cardiovascular diseases!
Full-fat dairy products play an active role in protecting liver, anti-inflammatory, anti-vascular oxidation, improving insulin sensitivity and improving postprandial insulin response, and are the basis for stabilizing blood pressure and lowering blood sugar.
The publication of The Lancet also shows that compared with people who don't eat dairy products, people who eat more than two servings of dairy products every day have a lower total mortality rate 17% and a lower cardiovascular mortality rate of 23%[ 1].
The nutritional value of milk is really high.
Second, how should middle-aged and elderly people choose milk?
In fact, the quality of qualified milk sold in the market is passable, but different people do have better choices.
1, the general elderly
The gastrointestinal absorption capacity of middle-aged and elderly people is getting worse, calcium loss and vitamin deficiency are obvious, and Chinese residents generally lack vitamin A. Milk with AD is one of the cheapest and most convenient sources of vitamins A and D, and middle-aged and elderly people can choose it in moderation.
2. Elderly people with cardiovascular diseases
Patients with cardiovascular diseases can choose low-fat milk and skim milk to reduce the intake of saturated fatty acids.
Skim milk, as its name implies, is "fat-free" milk.
Compared with whole milk, the contents of calories, cholesterol and fat-soluble vitamins in skim milk are also lower, but the nutrients such as protein, calcium and water-soluble vitamins in skim milk may be slightly lower, but the difference is not big.
3. Diabetic patients
Diabetic patients had better not choose low-lactose milk, because one molecule of lactose in low-lactose milk will produce two molecules of monosaccharide after degradation, which has a high glycemic index and will lead to a rapid increase in blood sugar of diabetic patients.
4. Patients with lactose intolerance
Lactose-intolerant people lack lactase in digestive tract and cannot digest lactose in milk, which will cause gastrointestinal discomfort after drinking milk. At present, there are many low-lactose milk with lactase in the market, and most of the lactose in this milk has been decomposed, which can reduce the intolerance problem.
When choosing milk, pay attention to the product label, choose milk marked with "low lactose" and "hydrolyzed lactose", or choose fermented yogurt.
Third, people with weak constitution should drink more milk.
Milk is rich in nutrition and can enhance physical fitness, but its physical fitness is not strong, that is, as the saying goes, "you can endure illness", and you can live longer if you are sick.
Milk plays an important role in regulating endocrine, immune system and microecological balance of intestinal flora, and can also improve immunity to some extent.
It is best to replenish milk every day after operation. Milk plays an important role in preoperative preparation, postoperative recovery and disease prevention. Older people may have some chronic metabolic problems, and experts suggest that milk be used as a supplement to daily food.
Back to the question at the beginning of this article, will drinking milk make people live longer? People's life span is influenced by many factors, but milk is indeed a relatively comprehensive and cheap nutrition. If the body is not intolerant, I suggest you develop a good habit of drinking milk every day.
