The nutritional needs of the elderly are more suitable for the elderly than certain proteins.

The age of the elderly, the decline of physiological functions and some living factors affect their nutritional status, showing some characteristics of nutritional needs.

If the elderly get energy at 1600 per day?
2000 kcal can meet the needs of the body.

If the energy obtained is lower than the recommended amount, malnutrition will occur.

With the increase of age, the elderly expect the supply of heat energy to gradually decrease. Generally speaking, energy absorption after 60 years old is reduced by 20%, and after 70 years old, it is reduced by 30%.

The total nutritional needs of the elderly are different from other groups.

This is because: the activity of the elderly is reduced, the metabolic rate of the body is reduced, the physiological function is reduced, and the ability to adjust and adapt to the digestive system is reduced.

This series of physiological changes has led to some changes in the nutritional needs of the elderly, showing a certain degree of particularity.

  First, the special nutritional needs of the elderly 1, protein protein synthesis capacity is reduced, the utilization rate is also low, so need to pay attention to supplement.

Usually, proteins are mainly divided into two categories. Eggs, milk, fish, shrimp, and lean meat are the sources of animal protein. Soybeans, nuts, and cereals are the sources of plant proteins.

  2, vitamin C vitamin C has antioxidant function, it can promote the biosynthesis of collagen, which is beneficial to the wound tissue; promote bone and tooth growth, enhance the strength of cholesterol wall, avoid blood seepage around bones and teeth; promote cheeseMetabolism of proline and tyrosine; accelerate the deamination of proteins or peptides, vitamin C can affect the metabolism of traces and lipids, improve the utilization of iron, calcium and folic acid, and act as a free radical scavengingThe agent increases the body’s ability to stress the external environment.

  3, vitamin E vitamin E is also a vitamin with antioxidant function, is a strong and effective free radical scavenger, can protect the body’s cell membrane and life macromolecules from free radical attacks.

Vitamin E has the function of improving the body’s immunity, maintaining the composition of red blood cells, regulating the synthesis of the body, promoting cell respiration, and protecting the lung tissue from air pollution.

Vitamin E can play a role in delaying aging, cardiovascular disease and cancer.

These important physiological functions of vitamin E have been confirmed.

  4, 姨 elderly should limit the intake of aunt.

Because too many hypertensive adults will develop hyperlipidemia and hypercholesterolemia, which can lead to hypertension, coronary heart disease and so on.

However, if the elderly suffer from excessive distribution restriction restrictions, as long as the control is within a reasonable range, no disease will be produced, which will be beneficial to health.

In general, the intake of feces in the elderly accounts for 20% of the total conversion introduced?
25% is suitable, and the vegetable oil with overlapping polyunsaturated fatty acids is the main one.

Of course, such as plasma, animal mites and so on should be eaten less.

  5, some elderly people like to eat sweet things, but after age, the elderly should limit the intake of sugar, especially pure sugar!

Because the elderly’s demand for sugar is reduced, resulting in excess sugar, a large amount of accumulation in the body, and sugar can be converted into sputum, making people fat.

Coupled with the reduction in the activities of the elderly, if the energy supply is too much, it is more likely to cause too much.

  Second, what protein is best?

  1, whey protein and whey protein extracted from milk is the “king of protein”, because of the most digestible absorption, the most reasonable amino acid composition, its bio-price reached 104, and almost branched-chain amino acids, forFor the elderly, not only does it not increase the burden on the digestive tract, but also promotes the synthesis of muscle proteins. Therefore, whey protein is the best source of protein supplementation for the elderly.

  2, food food supplement protein is the preferred egg, which has the highest metabolism in the body, if there is no cardiovascular disease, the elderly can 4-5 eggs per week, or add another egg white every day.

  3, milk milk protein absorption is also relatively high, the elderly can drink 300 ml of milk a day, if the usual meat intake is insufficient, you can drink 500 ml of milk a day to make up for the lack of protein caused by insufficient meat intake.

  4, meat meat is also irreplaceable to supplement high-quality protein, such as fish, shrimp, chicken, pork, beef, etc., can be more than 3-5 times a week, mainly fish.

  5, plant protein protein protein, tofu is high quality protein, is also not crystallizable, preferably 4-5 times a week or more.

The cereals should also eat more bean rice, bean paste, and eight-treasure porridge, which can complement the protein and increase the protein absorption of cereals. It is also the main auxiliary source of protein.
