There are 3 stages of human aging. Reminder: 6 kinds of 'aging agents' are hidden in food, it is better to eat less

The 36-year-old Ms. Zhao has been running a small restaurant by herself since she was 18 years old. In order to ensure the quality of food, she basically cooks by herself every day, facing various kitchen fumes for a long time.

She usually has a good physical fitness, but she found a lung problem during the physical examination years ago. Due to equipment limitations, the doctor suggested that Ms. Zhao go to a hospital in a neighboring city for a detailed examination, but Ms. Zhao thought it was troublesome and did not act immediately.

Until last month, Ms. Zhao coughed repeatedly for a month without improvement. Recalling her lung problems at the beginning of the year, she decided to go to a tertiary hospital in the city center for a careful examination.

Unexpectedly, this investigation turned out to be a malignant tumor in the lungs. Ms. Zhao couldn't figure out what caused her to suffer from lung cancer, since neither she nor her husband had the habit of smoking.

1. When does the human body begin to age? or from age 34

According to the 2021 "World Health Statistics" report, the average life expectancy of Chinese people in 2019 is 77.4 years, of which men live 74.7 years and women live slightly longer, reaching 80.5 years.

A study from the University of Cambridge found that after the age of 70, people will experience a cliff-like aging.

This is related to the sharp decline in the source of blood cells after the age of 70, even relying on only 10-20 stem cells, which leads to the abnormal production of blood cells, and a variety of aging-related diseases follow.

Previously, studies have found that the aging of the human body has three nodes, namely 34 years old, 60 years old and 78 years old . These three ages correspond to the three major watersheds.

The study came from the team of neuroscientist Tony Corey of Stanford University in the United States, through the research and analysis of 2925 plasma protein trajectories of 4263 subjects aged 18-95.

Finally, it was found that there is a certain relationship between certain protein molecules in blood plasma and aging at different ages:

At the age of 34 - the level of proteins related to appearance in the blood drops sharply, glial protein is lost, the human facial skin begins to wrinkle and relax, and the muscles begin to collapse;

At the age of 60 —hormone activity, binding function, and protein changes related to blood pathways peak, and the human body is obviously aging, not only in appearance, but also in behavior ;

At the age of 78 —the signal transduction of blood pathways and bone morphogenetic proteins changes drastically, the proteins related to aging diseases such as Alzheimer's disease and cardiovascular disease increase significantly , and the signs of aging are obvious.

It can be seen that aging follows certain physiological and biological rhythms.

2. Five kinds of food are "aging catalysts" and should be removed from the dining table as soon as possible

Aging is an unavoidable biological law, but affected by certain factors, some organs have not yet reached the point of aging, but they are aging ahead of schedule.

1. Heart: trans fat

After the age of 40, the heart begins to age. Especially men over the age of 45 and women over the age of 50 have a significantly increased probability of developing cardiovascular disease.

Processed meat, alcohol, high-salt, high-sugar and high-fat ingredients in food, as well as artificial vegetable oil, margarine and other artificial trans fats will damage the health of the heart and accelerate its aging.

2. Skin: High-salt food

The skin ages earlier, generally around the age of 25, when the body's synthesis of collagen slows down, the skin will gradually lose its elasticity, and fine lines will begin to increase.

The skin has a lot to do with eating too salty. If you eat too much salt, there will be more sodium ions in your body, which will more easily accelerate the loss of skin moisture , leading to increased wrinkles and freckles.

3. Liver: Alcohol

After the age of 45, the venous blood flow rate and blood flow in the liver will decrease year by year. After the age of 65, the slowing rate of liver blood flow reaches 35% of that of adults under 40 years old.

The liver is the detoxification and metabolism organ of the human body. Alcohol and drugs must be metabolized by the liver . Both drug toxicity and alcohol toxicity can stimulate liver cells and cause oxidative stress, thereby accelerating aging.

4. Lungs: Tobacco

The weakening of lung function is also relatively early. The muscles that control breathing at the age of 20 gradually become stiff, which increases the residual capacity of the lungs. Generally, at the age of 40, the lungs will accelerate aging.

The air environment is the key to lung health. Long-term inhalation of lampblack, cigarettes, PM2.5, etc. are the "culprits" that induce lung diseases , accelerate the aging of the lungs, and induce the appearance of lung diseases.

5. Stomach: Big fish and meat, high-salt food

The age of the stomach is similar to the actual age, and it generally begins to age around the age of 45. The most direct manifestation is the atrophy of the gastric mucosa. If the stomach is larger than the actual age, it means that the stomach is aging in advance.

The appearance of "aging stomach" has a lot to do with eating and drinking, drinking and smoking, and pickling food. Especially high-salt and pickled foods are risk factors for gastric cancer , so if you want to nourish your stomach, you should eat less pickled foods on weekdays.

3. Is the "anti-aging diet" reliable? teach you how to eat

There are "anti-aging recipes" constantly flowing out on the Internet, claiming that regular consumption of these foods can delay aging or even reverse the aging process. Are these diet plans really reliable?

Recently, a research review published in "Science" analyzed the anti-aging dietary strategies. The review judged animal experiments on dietary intervention methods and found that these calorie-restricted diets are more or less effective in prolonging the lifespan of animals. played a positive role.

Can humans replicate the same effect? The author of the review is cautious about this. He pointed out that the living environment of human body and experimental animals is quite different, and the diversity of human living environment may offset the effect of dietary intervention .

In addition, it has also been found in animal experiments that specific breeds of animals do not benefit from a calorie-restricted diet.

At present, there is no clinical research to clarify the effect of calorie-restricted diet on human anti-aging, and there are still many unknown effects and risks in the anti-aging diet , which require further research for inference.

Stretching - Is Your Eating Pattern Anti-Aging? test yourself

Although the current anti-aging diet pattern has not yet clarified its effect on the human body, adhering to a healthy diet pattern can play an important role in delaying human aging.

**1. Satisfy the following, indicating that the intake of antioxidant substances is sufficient , which helps to resist the aging of skin and body tissues:

• Can eat 200 grams of dark green vegetables every day;
• Staple foods involving whole grains, beans or potatoes;
• Eat half a catty of fruit and a small amount of nuts every day.

2. If the following two conditions are also met, it means that adequate protein intake can prevent sarcopenia:

• Drink 1-2 small cups of live bacteria yogurt every day;
• Eat tofu, dried tofu and other soy products more than 4 times a week

3. If there are supplements to these diets, it means that calcium intake is sufficient, which helps prevent osteoporosis :

• Eat no less than 50 grams of meat or fish per day;
• Every meal is guaranteed to eat three types of food: staple food, vegetables and high-quality protein.

4. Doing this shows that the diet is regular, the food diversity is high, the total calories are well controlled , and it is conducive to maintaining a good figure. It is a healthy eating pattern:

• Regular and quantitative meals for three meals;
• Eat less fast food;
• Eat more than 12 kinds of ingredients every day;
• Keep 70% to 80% full, not overstuffed;
• The cooking temperature of dishes is relatively low, and I like cold salad, stew and steam;
• Drink more than 6 cups of water or light tea a day, and do not drink sweet drinks.

Unexpectedly, food is also closely related to aging. How do you eat three meals a day? Do you like foods that tend to accelerate aging? If it is, it must be corrected in time so that the organs can "grow old" like you.
