Lao Zhang, who has just passed the year of the flower armor, attaches great importance to health. Earlier, I heard that eating vegetarian food is better for the body, so Lao Zhang began to prepare three meals a day for vegetarian recipes.
After eating vegetarian for many months, Lao Zhang initially felt relaxed, until some time ago, he suddenly felt that he was very tired, top-heavy, and sometimes his eyes would be black.
Worried, Lao Zhang went to the hospital for a test, and the results suggested: iron deficiency anemia. Lao Zhang was very puzzled, his body has always been strong, how can he be anemic for no reason?
Many elderly people are confused, obviously usually based on vegetable coarse grains, do not eat much meat, how can the body become worse? Does the elderly really help prolong life by not eating meat? A study by Tsinghua University may subvert many people's ideas...
<h1 class="pgc-h-arrow-right" data-track="43" > Tsinghua study: eating more meat may prolong life</h1>
Aging Cell, a top professional journal in the field of aging, published a latest research result by Wang Zhao of the School of Pharmacy of Tsinghua University, which used mice as experimental subjects and fed them on a high-fat diet.
The results of the study found that a high-fat diet can prevent insulin signaling pathways, improve the metabolic abnormalities of SIRT6-deficient mice, effectively alleviate multi-tissue organ atrophy and dysfunction, and clearly save the resulting loss of life.
From birth to death, the human body seems to have undergone a cycle. From weakness in infancy to strength in adulthood, and again physical weakness in advanced age. Even if the body does not have major diseases, in the advanced age state, the structure of various tissues and organs will also appear abnormal and functional decline. The decline of tissues and organs will undoubtedly bring diseases such as sarcopenia, decreased bone density, heart and kidney failure and so on.
The study found that, especially in the elderly at the end of aging, appropriate supplementation of fatty foods can improve the cachexia state of the disease or the end of aging by improving the body's lipid metabolism, reducing glucose metabolism, and then systematically intervening in the body's metabolic mode.
<h1 class="pgc-h-arrow-right" data-track="78" > Second, the elderly do not eat meat, what will happen to the body? </h1>
This study by Tsinghua University has shattered people's stereotypes about diet for the elderly. Many elderly people think that eating meat will cause cancer, gain weight, raise blood pressure, etc., so as to choose to eat more vegetarian, but long-term do not eat meat, but will bring a lot of harm to the body...
1. Reduce immunity
Although protein can be obtained through plant protein, the high-quality protein contained in meat is more easily absorbed by the body. If you eat vegetarian for a long time, when the protein intake is insufficient, it will directly reduce the immune system's ability to resist.
2. Iron deficiency anemia
The iron contained in meat is heme iron, which is an important source of iron in the human body. Even vegetables contain iron, but only one-tenth of that of meat. Often do not eat meat, it may be like Lao Zhang, causing iron deficiency anemia.
3. Easy to grow stones
Plant foods contain more oxalic acid, and a large amount of oxalic acid is concentrated in the human body, which is easy to calcifiate in the body, thus forming stones.
<h1 class="pgc-h-arrow-right" data-track="79" > Third, the elderly eat meat, eating is very important</h1>
The elderly want to eat meat, but not a lot of food, no restraint. Zhejiang Nutrition Society said that the dietary principle of the elderly should be based on food diversity, reasonable collocation, and compliance with balanced dietary requirements.
It is recommended that the elderly often eat aquatic products, livestock meat and eggs, with an average daily intake of 50g to 100g of fish, shrimp and poultry food, 25g to 50g of eggs, 40g to 50g of livestock meat (lean), and 250g to 300g of fresh milk or an equivalent amount of dairy products per day. The average daily intake should be 15g to 25g of soybeans or equivalent soy products.
In order to meet the daily protein intake, while ensuring food diversity and nutritional balance, it can be arranged like this:

<h1 class="pgc-h-arrow-right" data-track="80" > four, over 50 years old, you may wish to eat more of these 2 kinds of meat</h1>
With age, stomach motility deteriorates. The older many people get, the less often they eat meat. But if you eat too little, the more serious the aging of the human body, and the body will fall into a dead cycle. In fact, there are two kinds of meat, the elderly may wish to eat more, not only to meet the nutritional needs of the body, but also beneficial to the body.
1. Fish
For example, grass carp, mandarin fish, carp and so on. Fish contains very little fat and contains a large number of unsaturated fatty acids, which can effectively reduce the viscosity of the human blood and prevent the occurrence of cardiovascular and cerebrovascular diseases. Fish meat is also rich in mineral elements, which have the effect of preventing thyroid diseases and Alzheimer's disease.
2. Chicken
Chicken is also considered to be a meat with less fat content, especially chicken breast meat has a high protein content, low fat, and is easily absorbed by the human body; not only chicken, eggs contain lecithin, which is very important to the human body, which can effectively promote the development of the human brain and multiple organs.
Don't be misled by the fact that the elderly should not eat meat. As long as you master the correct way to eat meat, the appropriate amount of fat intake is more conducive to improving physical function and delaying aging.
