14% less calories and one-third longer survival? Yale University: Diet Affects Human Lifespan

As the saying goes, there are only a few bowls of rice in life, and whoever eats it first goes first. On the surface, it looks a bit bluffing, but in fact, from a scientific point of view, there is still some truth.

In the past, living conditions were not so good, and everyone’s diet was not so complicated. Nowadays, all kinds of “technology and hard work” are on the table. Coupled with unreasonable eating habits, it is easy to cause obesity, gastrointestinal discomfort, cardiovascular disease, and old age. Dementia and even cancer. And Yale University has found that diet can even directly affect human lifespan.

1. Yale University: Reduce calorie intake and prolong survival by one-third

Recently, Yale University conducted a study on the popular "calorie restriction" in the academic world. Based on the actual performance of the human body, they found that the daily calorie intake of the subjects was reduced by 14%. After a period of time, they found that many of their physiological indicators tended to be "young". This is equivalent to extending the lifespan by nearly one third (28%), and the relevant results were published in the well-known academic journal "Science".

Prior to this, the US NIA also conducted a similar primate study. 120 rhesus monkeys were divided into two groups of the same number. One group reduced food intake by 30% every day. It was found that nearly one-third of them One of the monkeys survived to double their lifespan.

In addition to the research of American scientists, the University of London in the United Kingdom also has similar results. They found that reducing food intake by 40% may prolong life by 20 years, and this result was also published in the sub-journal of "Cell". Researchers believe that after reducing calorie intake, the risk of obesity in the human body will be reduced, and 13 types of cancers are currently associated with obesity, and more than 2.8 million people worldwide die prematurely due to obesity each year.

2. What is the scientific principle behind reducing calorie intake?

In addition to reducing obesity-related premature death factors, reducing calorie intake actually has more original intentions. Scientists have found that when excessive food is ingested into the human body, a large number of oxygen free radicals will be produced. When it cannot be removed in time and accumulates too much in the body, an "oxidative stress" reaction will occur, which is likely to cause inflammation, changes in protein properties, and lipids. Peroxidation, etc., thereby damaging cells and the body, and accelerating the process of human body attenuation and disease.

Moreover, reducing calorie intake can regulate multiple signaling pathways in cells, promote the transmission of various proteases in cells, and reduce glucose and insulin levels. However, for many people, it is difficult to control their diet every day, so for them, reducing calorie intake may not be a good way.

But what is gratifying is that Harvard Medical School has discovered a human endogenous substance, which can also act on the human body, and has the effect of activating human cell pathways and maintaining normal cell responses. In their study, "Biosc" activates the Sirtuins pathway by directly producing endogenous substances needed by the body. Sirtuins are important mediators of the mTOR pathway, opening the AMPK pathway by promoting the deacetylation of liver kinase B1, thereby promoting autophagy in senescent cells and prolonging biological life expectancy.

Nowadays, "Biosc" substances have become an intervention method that can be ingested orally in China. With the capital and technical support of biotechnology companies, they have flowed into the world and become the first popular life technology in China. Retrieving the relevant data of International Bio-Dong, it can be seen that "Biosc" is acquired by nearly one million "millionaires" in first- and second-tier cities at a monthly cost of four figures, and the tens of thousands of positive feedback left are currently more about sleep and energy. aspects of improvement. As for whether it can successfully stretch the lifespan of aged subjects by 30% as in the study by the University of Washington, it may only be possible to wait for time to give the answer.

3. In addition to "calorie restriction", what else is there to pay attention to in diet?

Speaking of the benefits of eating less and reducing calorie intake, many friends are eager to try it. In fact, "eating less" is also learned. What is seven points full? The general definition is that there is still some space in the stomach, but there is no desire to continue to eat more, and there is no feeling of hunger in the stomach. Keeping this seven-point full state, people are not easy to get hungry in advance, and it is not easy to get fat.

And to achieve seven full, then pay attention to these things in the eating process:

The first is the order of diet. Generally speaking, you should drink light vegetable soup first, then consume materials rich in dietary fiber, then eat lean meat and fish rich in protein, followed by staple foods such as rice and grains.

The second is eating habits, pay attention to chewing slowly, and eat no less than 20 minutes. Furthermore, the interval between each meal is 4-6 hours, so that the stomach has enough time to digest. And, if you really feel hungry, you can properly consume some yogurt, fruit, nuts, etc., which is better than eating snacks.

The third is the treatment after accidentally eating braces. In the face of gourmet food, many people are hard to resist, so it is easy to suffer from overeating. In this regard, we can rub our stomach clockwise around the navel after eating, or we can stand against the wall to help burn calories, or drink a moderate amount of yogurt and apple cider vinegar to help digestion.

In short, diet is learned, and the impact of reducing calorie intake on life expectancy does seem to matter now, but we can’t be blind in this process, we need to follow a scientific method, so as to avoid harm to the body.
