Why do old people eat meat?
Compare the human body to a car, then our diet is like gasoline. Constant eating can ensure that the car has power and can run, but is there enough gasoline? Friends with a little common sense should know that in order to ensure that the car can run longer, lubricating oil and engine oil are needed.
We usually eat many kinds of food, such as vegetables, staple food, meat, beans, seafood and so on. The nutrition of each food is different, and only diversified intake can ensure a balanced nutrition. Meat is rich in high-quality protein, which is an important substance necessary for human body. In addition, there are nutrients such as fat, minerals and trace elements, which are indispensable. Only by eating meat properly can the human body supplement these nutrients.
If the elderly eat less meat, they can't maintain their normal physiological functions. After a long time, there will be a series of adverse reactions, such as fatigue, muscle weakness, emaciation, anemia, unresponsiveness and so on. For the elderly, the lack of protein will accelerate the loss of calcium, affect the strength of bones and muscles, limit joint activities, make the limbs inconvenient to move, and lead to fractures and increase the risk of disability.
Eating less meat seems to be beneficial to blood pressure and blood lipid in a short time, but it will increase the risk of hypoglycemia and endocrine disorders in the long run, which can not be said to be a healthy way. Therefore, the elderly should eat meat properly, which is helpful for strengthening the brain, nourishing bones and protecting blood vessels.
How to eat meat scientifically?
Old people should not eat less meat, but should learn to eat meat scientifically. As long as you are not allergic to meat, you can rest assured that you can eat all the pork, beef and mutton you usually eat. Dietary guidelines for China residents point out that the elderly should supplement 60 grams of protein every day and convert it into beef. 100g beef contains 20g protein, while100g beef is almost as big as the palm of your hand. In other words, eating a piece of beef every day and then matching it with bean products can basically meet the needs of protein.
In the choice of meat, white meat is better than red meat, mainly chicken, duck, goose, fish and shrimp, supplemented by pigs, cattle and sheep. No matter what kind of meat you eat, it is best to remove the skin and fat on the surface and strictly control the intake of fat. In practice, it is necessary to eat less oil and salt, but it is not necessary to eat boiled meat and no salt for every meal. Salt can be put, but it should be put less, and it is healthier to control it within 6 grams a day.
What problems will a light diet bring?
People's understanding of light diet is different from what doctors say, lacking protein and fat. In the long run, there will be nutritional deficiency, which will have a negative impact on the body. For example, reducing the sensitivity of insulin, if the elderly eat less meat, they will definitely increase the proportion of staple food in order to fight hunger. Foods such as rice and steamed bread are ok, which will affect insulin metabolism and increase the probability of resistance, which is very dangerous for diabetic patients.
The lack of protein and fat can also lead to the decrease of trace elements, which mostly occurs in female patients, such as anemia caused by iron deficiency, neurasthenia, insomnia and anxiety caused by vitamin B 12 deficiency. It will also affect the absorption of vitamins and have a certain impact on skin, mucosa and vision.
So it is wrong to eat less meat when you are old. Meat is edible, so you should choose it scientifically. Eating right can help you strengthen your brain, nourish your bones and protect your blood vessels.
