Milk powder contains a lot of vitamins
Generally speaking, if conditions permit, it is best to drink fresh milk instead of milk powder. First of all, compared with milk powder, the nutrients such as protein, vitamins and minerals in fresh milk are easier to digest and absorb. Secondly, fresh milk contains more calcium and has a high calcium absorption and utilization rate. Especially for middle-aged and elderly people who are prone to osteoporosis, fresh milk has a better calcium supplement effect.
Milk powder is made from fresh milk after being concentrated and spray-dried. Compared with fresh milk, the utilization rate of protein and amino acids in milk powder is reduced to varying degrees and is not easily absorbed by the human body. More importantly, during the production process of milk powder, some nutrients, such as water-soluble vitamin B1 and vitamin B2, niacin and vitamin C, are destroyed. In particular, the damage to vitamin C is very serious. 100 grams of fresh milk usually contains 1 mg of vitamin C, while the content in powdered milk is much less than this. However, compared with fresh milk, milk powder also has its advantages, such as easy storage and transportation, and there are many types of formula milk powder, which can meet the nutritional needs of special groups of people.
In recent years, many nutritionally fortified milk powders with added iron, calcium, and zinc have appeared on the market. These substances are specially added to milk powder because they are generally lacking in our daily diet. Although this is a good thing, whether these mineral elements can be well absorbed and utilized by the human body is a question that is questioned by academic circles. First, during the production of milk powder, certain processes will destroy the activity of these minerals and reduce their absorption rate; second, the storage time of milk powder is relatively long, and after two or three months, these added minerals will also be lost. active and cannot achieve the corresponding nutritional enhancement effect.
In addition, because the saturated fat content in milk is relatively high, accounting for about half of the entire fat content, it is best for the elderly to choose low-fat products whether they drink fresh milk or milk powder. Milk is rich in nutrients, but many elderly people with weak spleen and stomach suffer from diarrhea as soon as they drink milk. Therefore, nutrition experts suggest that it is best for the elderly to choose specialized formula milk to supplement their body needs.
Because the elderly lose a lot of nutrients and absorb nutrients slowly, it is very difficult to meet their nutritional needs with daily diet alone, so additional supplements are necessary. Formula milk can provide targeted nutritional supplements for the elements that the elderly lack, in order to achieve a comprehensive nutritional balance. Especially the elderly suffering from certain chronic diseases need targeted nutritional supplements. In comparison, pure milk contains fewer specific nutrients, such as iron, vitamin E, zinc, etc. Therefore, the elderly should choose formula milk.
Senior formula milk is specially developed according to the physiological characteristics of the elderly. That is to say, some nutrients that the elderly do not normally absorb are added and strengthened by the formula milk. Taking vitamin E as an example, a 65-year-old elderly person needs about 100 mg per day, but the daily diet can only provide an average of 70 mg. Drinking formula milk can make up the remaining 30% of the difference. In addition, in addition to meeting the basic nutrition of the elderly, formula milk for the elderly also specifically fortifies long-chain unsaturated fatty acids, such as DHA, which can enhance memory and prevent intellectual deterioration of the elderly; EPA, which can prevent cerebrovascular disease in the elderly. diseases; nucleotides can enhance the immunity of the elderly; taurine is the main nutrient for cranial nerves.
For the elderly who are healthy and have good living habits, drinking natural pure milk can achieve nutritional supplementation with a nutritionally balanced diet, and there is no need to drink formula milk.
