How many people still rely on dieting to lose weight and maintain health?
Earlier this month, another person on a restricted diet was admitted to the hospital and was on the trending search! A 22-year-old girl in Shandong has been on a long-term diet to lose weight. In the end, her face was sallow and she was sent to the hospital in a wheelchair. The doctor diagnosed that she had suffered from fatty liver due to excessive dieting.
Restricted diets seem to have become a trend in recent years. Searching for restricted diets on the Internet always fails to jump out of various methods such as “ketogenic diet” and “light fasting”. It is really suitable for everyone. ?
I. New research from Peking University: eating less may delay aging and prolong life
In order to verify Whether eating less can delay aging, Liu Ying, a professor at the School of Future Technology of Peking University, conducted a set of experiments with nematodes as the main experimental objects.
The aging process of nematodes is highly similar to that of humans. For example, the skin of nematodes will have the same folds as human skin, and the amount of food intake by the nematodes will also be significantly reduced, and the body structure will also change.
In this experiment, scientists induced mutations in the eat-2 gene in nematodes through a special chemical reagent. Through the data record, it was miraculously found that after the gene mutation, the nematode’s food intake was greatly reduced, and the life span was 2 times longer than the original. In other words, the less you eat, the longer your life expectancy.
Second, the question is, is human dietary restriction equally beneficial to health?
Of course, humans and animals are different after all. The results of animal experiments cannot be used mechanically and without analysis for clinical treatment.
Speaking of “reducing food intake”, as early as the “Yellow Emperor’s Classic of Internal Medicine”, it was mentioned that “diet is in moderation”, and modern overeating affects the normal transportation and transformation of spleen and stomach functions. May lead to obesity, diabetes, nutrition-related cancers, and more.
Xu Xinzhu, a nutritionist from the Clinical Nutrition Department of Guangdong Provincial Hospital of Traditional Chinese Medicine, said that our human body undergoes metabolism every day, and the cells involved in metabolism will undergo an excretion process after aging. In a state of starvation, it may stimulate the self-cleaning function of cells and strengthen the ability to deal with viruses and bacteria
It is worth emphasizing that moderately restricted diet< /strong>, for example, for people with excess energy, short-term dieting is a kind of buffer conditioning for the body, and it is feasible. However, if extreme dieting or starvation therapy, it may damage the function of organs, which will have a greater impact on the human body.
How to eat three or three meals a day, Zhong Nanshan’s longevity menu can refer to
Modern Wealth disease is high, Academician Zhong Nanshan of the Chinese Academy of Engineering has long suggested in public that it is better to eat less than to eat enough, and eat only 80% full.
1. Calories for three meals a day: 3:4:3
The scientific eating habit is: Have a full breakfast (30%) , eat well for lunch (40%) and eat less for dinner (30%). The diet should be reasonably matched, and consciously increase the protective nutrition, such as vitamins, carotene, dietary fiber, etc.
2. Diverse diets
Diverse diets are good for health, 30 or more different foods should be consumed in a week , or eat more than 12 different foods in a day. This is the ideal diet for consuming essential nutrients. For example, vegetables, fruits, grains, meat, seafood, dairy products, beverages, etc. are all involved.
3. Eat meat carefully
Although red meat is classified as a second-class carcinogen , but that doesn’t mean going to the extreme — completely refusing to eat red meat. Red meat contains high-quality protein, which can provide the body with plenty of calories. Red meat is also rich in minerals and is suitable for people who are deficient in iron. Therefore, meat can be eaten, but try to minimize cooking meat by smoking, grilling, marinating, etc., and steaming and stewing can be used.
Fourth, delaying aging and improving the quality of life, it is more important to do these things well
Compared with restricting diet to fight aging, in daily life, Xiao Ai is more It is recommended that everyone delay the passage of their youth by developing good living habits and a balanced diet.
1. Eat less unhealthy food
Long-term consumption of unhealthy food such as fried food and processed food can easily lead to various diseases and speed up body organs ageing, which in turn promotes aging.
2. Stay up late, keep a good attitude
Staying up too often can lead to endocrine disorders, poor spirit, rougher skin, and possibly immune Decreased strength, frequent colds, gastrointestinal infections, allergies, etc. The same is true for long-term negative emotions. Maintaining an optimistic mood is an important factor in anti-aging. Keeping a smile often can regulate your mood and help burn calories.
3. Stay away from tobacco and alcoholstrong>
Nicotine has a constricting effect on skin blood vessels, which can cause premature wrinkles on the skin of smokers, making them look older than their peers; drinking alcohol reduces the amount of oil in the skin and promotes dehydration. Indirectly affects the normal function of the skin and promotes aging.
There are many ways to slow down aging, not just by dieting alone. Excessive dieting may lead to unbalanced nutrition in the body, leading to metabolic disorders and accelerated aging.
