The nutritional value of milk has been widely recognized, but only proper drinking methods can play a proper role in health care. Elderly people, especially those with osteoporosis, iron deficiency anemia, abdominal postoperative patients, and those who need to take antibiotics for a long time, should drink milk and drink milk. More attention is to be paid to the fact that milk is the world's nutrient health food. , is a natural food with a wide range of nutrients, sufficient quantities, and high quality.
Milk protein has high nutritional value, easy digestion and absorption, rich in minerals and trace elements, and low cholesterol content. It is a nutritious health drink that is particularly beneficial to the health of the elderly. Although the nutritional value of milk is high, improper drinking methods do not provide the necessary health care. Some elderly people have only a glass of milk for breakfast because they eat less. In this way, valuable high-quality protein in milk does not provide the body with certain physiological functions such as repairing, renewing tissue, improving immune function, and promoting metabolism. This is actually a waste.
The correct method should be to eat a certain amount of starchy staple foods such as rice and noodles, and then drink milk. In this way, starchy foods provide the energy needed by the body and the protein can fully exert its physiological functions. The need to pay attention to the way milk is consumed. Experiments have shown that drinking small amounts of milk several times a day is more direct than drinking once, and calcium absorption rate is higher. Therefore it is recommended to drink 500 ml of milk 2 to 3 times a day. Since milk contains a hypnotic substance, it can drink about 200 ml of milk half an hour before bedtime.
Freshly sterilized milk does not need to be boiled, and can be consumed after being warmed; the sterilized milk stored refrigerated overnight can be heated and boiled. Never boil it repeatedly because it will destroy the vitamins contained in milk and reduce the nutritional value of milk. . Osteoporosis and fractures caused by it severely affect the quality of life of the elderly. Nutrition survey reports show that calcium intake is closely related to the occurrence of fractures. If the daily calcium intake is less than 470 mg, the risk of fractures is 2.5 times the daily calcium intake of those who exceed 750 mg.
The current variety of calcium supplements on the market is dazzling, in fact, milk is a calcium supplement, both economical and affordable. A survey of bone mineral density and related factors in 286 people over the age of 50 showed that bone mineral density showed a downward trend with increasing age. Moderate exercise and frequent drinking of milk can delay bone mineral density and prevent fractures. Lactose contained in milk has the effect of promoting calcium absorption. The calcium and phosphorus ratio is suitable and the absorption rate is high. It is a good food source for calcium supplementation. The recommended supply of calcium for the elderly is 800 mg per day. 100 milligrams of calcium per 100 milliliters of milk. In this way, 500 milliliters of milk is consumed every day, and the calcium provided in other foods can satisfy physiological needs.
China's diet is dominated by plant-based foods, and consumption of dairy products is low. Many elderly people do not have the habit of drinking milk for a long time. The activity of lactase in the body is low, and some elderly people may experience lactose intolerance. That is, after drinking milk, abdominal pain, bloating, diarrhea and other symptoms occur. Older people who have these conditions can change to yogurt and cheese instead. Yogurt is made by fermenting live lactic acid bacteria with freshly sterilized milk. Lactose has been decomposed into lactic acid and therefore does not cause lactose intolerance.
Yogurt has many other advantages over milk. First of all, it is acidic, not only can promote digestion, and the calcium in yogurt has been converted to calcium lactate, easy to absorb; Second, live Lactobacillus in the intestine to inhibit the growth of spoilage bacteria. Spoilage bacteria can produce a large number of toxic metabolites such as hydrazine, hydrogen sulfide, amines and phenols. If they are not detoxified in time, they will lead to liver dysfunction and circulatory disorders, interfere with the nervous system and affect sleep.
Lactobacillus can inhibit the growth of these spoilage bacteria in the intestinal tract, thereby suppressing the production of harmful metabolites. In addition, live Lactobacillus can also regulate the intestinal flora. It is particularly important for those elderly people who need long-term use of broad-spectrum antibiotics due to chronic diseases. It is recommended to take a cup of yogurt while taking antibiotics to reduce the side effects of antibiotics.
In addition, milk should be taken with caution in the condition of some diseases. Iron deficiency anemia patients should not drink milk in large quantities, because calcium in milk can prevent iron from converting into divalent iron ions in the digestive tract, which is not conducive to the absorption of iron. Patients after abdominal surgery are also advised not to drink milk, drink easily lead to abdominal flatulence or diarrhea, affecting recovery. In recent years, studies have found that drinking urine in patients with urine transferase deficiency can cause eye lens lesions and accelerate the generation of senile cataracts, so patients with a family history of cataracts should not drink milk. However, ordinary elderly people can safely drink milk.
In short, most elderly people only need to drink 1-2 cups of milk a day, and pay attention to scientific drinking methods, they can make full use of the nutritional value of milk, so that elderly friends get a good health and health.
