Chronic diseases have become more and more frequent in recent years, especially the phenomenon of the three highs. Therefore, for many elderly friends, they will stand completely opposite to meat. Many elderly people do not eat any meat, and the elderly have always believed that "it is hard to buy a lot of money to lose weight when they are old." Eating more vegetarian food to make themselves lose weight, which is more conducive to their health.
1
Is the elderly really good?
First of all, the elderly do not eat meat. At the beginning, they can indeed reduce their weight and reduce their three highs, but after a long time, it will also bring many problems.
First of all, malnutrition will occur when weight is lost, because ingesting protein and fat will decrease, will also decrease muscle strength, and the flexibility of the joints will decrease.
Secondly, if you only eat vegetarian food, nutrition is relatively single, The gastrointestinal ability of elderly friends is relatively weakened, and they lack the absorption of nutrients. If you don’t eat meat, you may experience malnutrition, low blood sugar, etc., which may even affect the normal function of the organs.
The body lacks nutrition and weakens muscle strength. What follows is that 's resistance decreases, makes it easy to catch a cold. Occasionally, a little bit of wind and cold may lead to a serious illness.

What benefits will the elderly bring to their bodies appropriately?
Strengthen the strength of skeletal muscles and myocardium
Muscles require a lot of energy when working. Usually, the concentration of carnitine in the muscles is at least 200 times higher than that in the blood. Of the energy required by the muscles, 70% of the html needs is provided by fat.
There is data that shows that the amount of carnitine in mitochondrial in heart cells decreases with age, and the mass and strength of skeletal muscle will also decrease with age.
According to the analysis of muscles of healthy people of different ages, the content of carnitine in the muscle tissue of the elderly is significantly reduced. If of the elderly aged 70 to 92 years old is supplemented with 4 grams of carnitine in a day, their muscle strength will be significantly increased and the fat in the body will also be reduced.
has been shown to prove that the decline in immune function with age is the most obvious aging phenomenon, and carnitine also plays an important role in maintaining normal immune function. Therefore, fat oxidation can better meet the energy demand of immune cells than oxidation of carbohydrate .
delays brain aging
The cell membrane of brain cells is composed of a large number of unsaturated fatty acids, and the oxidative and metabolic reaction of brain cells is very active. Brain cells are easily damaged in oxidation reaction , which is an important reason for brain aging.
The memory loss of the elderly is caused by the reduction of choline. If is supplemented with 4 grams of carnitine every day, the mental state of the elderly can be significantly improved.
Because the structure of carnitine is similar to that of acetylcholine , supplementing carnitine can restore the activity of acetylcholine esterase that plays a neurotransmitting role in brain tissue, so supplementing carnitine can increase the concentration of antioxidants in the elderly.

The older you are, the more you want to eat meat? Authoritative study: 2 taels of meat a day, elderly people may be susceptible to heart disease
Recently published in the journal Arteriosclerosis, thrombosis, and vascular biology, a new study led by scientists from the Cleveland Clinic Lerner Institute and the Friedman School of Nutritional Science and Policy at Tufts University, which investigates the meat intake of more than 4,000 men and women over 65 years of age in the United States.
The final result found that more meat intake was related to the increased risk of atherosclerotic cardiovascular disease. Eat a little bit of meat every day, and the risk was about 22% higher than that of , but the risk increased, and it was only related to red meat, and this was not found in poultry, eggs and fish.
Why does eating red meat increase this risk?
Because when the nutrients present in red meat (L-carnitine ) are metabolized in the intestine, intestinal bacterial flora will produce specific metabolites - trimethylamine N-oxide, γ-butyl betaine and croton betaine . These metabolites may cause atherosclerosis and an increase in the risk of sexual cardiovascular disease.

How should the elderly eat meat correctly?
55 stew more and stir-fry more
It is best for elderly friends to choose the stew method, do not choose the good method, because the broken meat is spicy and soft, while the chewing ability of the elderly friends mostly declines. The stewed meat is softer, and it is more conducive to digestion. Moreover, uses the stew method, which can reduce fatty acids by 30% to 50%, and unsaturated fatty acids will increase, and has higher nutritional value.
Pay attention to matching
When eating meat, elderly friends should also pay attention to matching. For example, chicken and mushrooms are paired together. not only increases the fishy smell, but also has higher nutritional value. can match soy products when eating pork and beef, so that cholesterol and fat particles will be smaller. fish and tofu should be better matched together. because tofu contains more calcium, and fish contains more vitamin D. These two are more conducive to the absorption of calcium.
Choose the right meat that is suitable for eating
Eating meat appropriately is more beneficial to health for the elderly. When eating meat, it is best to choose fish, shrimp, chicken, pigeon meat, etc.
