Genes and the environment affect the length of human life. In the study of identical twins, scientists predict that the impact from genes may not exceed 30%, which means that the vast majority of human life is dominated by the environment. Of the many environmental impact factors, almost no one has been deeply studied and discussed like diet. For example, the calorie intake limit is one of the areas being studied.
Compared to “how to eat”, “what to eat” is also a hot topic of research. Meat consumption is often placed under a microscope for research. In one study, which tracked nearly 100,000 Americans for up to five years, it was found that during the study, meat eaters were more likely to die for various reasons than vegetarians. This was manifested in men. More significant. A number of comprehensive analyses combined with several other studies have also shown that low-meat diets are closely related to human longevity, and that the longer they persist in a meat-free diet, the more they can benefit from it. However, not all research results agree. Some results indicate that the length of life has little or no relation to meat eaters and non-meat eaters.
A major study found that vegetarians had significantly lower mortality than meat eaters. The study, published in the Journal of the American Medical Association’s Internal Medicine, rekindles the debate over the increasingly popular vegetarian diet when medical advice conflicts with the health impact of vegetarian diets on supporters. However, care must be taken when interpreting the results because the risk of death is not only related to diet, but other more complex social and environmental factors can also affect the outcome. For example, vegetarians tend to be younger than the general population, so the mortality rate is much lower. Similarly, the social background of vegetarians may be more affluent, which will also affect mortality.
So, can we confidently say that we can extend our lifespan without eating meat? The answer is simple: not yet.
People have a longer life than most other organisms, whether they are researching or investigating, whether they are animal experiments, or analyzing existing health data, or recruiting volunteers to observe for a period of time. The conclusions are all certain measures and longevity. The relationship between them does not mean that the cause and effect, such as vegetarians are more prone to longevity, it may be because vegetarians exercise more, smoking and drinking less. Therefore, if you want to live longer and you want to get sick younger, you have to control as many environmental factors as you can, including diet, and try to eat as little meat as possible.
Nutrition research also relies on volunteers to accurately and truthfully record their food intake. But this cannot be taken for granted. Studies have shown that people tend to underreport calorie intake and overstate health food consumption. Without actually controlling people’s diet and measuring how long they lived, it is difficult to have absolute confidence in the results of the survey. The study also found that foods such as fruits, vegetables, nuts, and legumes that are eaten regularly by vegetarians can help reduce the risk of cancer, heart disease, and type 2 diabetes, help control body mass (BMI) and waist circumference, and promote Brain health.
Scientists in Britain and the United States have compared the microorganisms in the intestines of meat eaters and vegetarians and found significant differences. When the microorganisms contained in the intestines of meateaters interact with digestive fluids, the chemicals produced are believed to cause cancer. This also explains why colon cancer is common in meat-dominated regions such as North America and Western Europe, but it is rare in India where vegetable-based foods are dominant.
In other words: relevance does not equal causation. It seems that vegetarianism and longevity are related, but different variables can explain this link. For example, vegetarians may exercise more than those who eat meat, smoking less and drinking less. From the available evidence, a meatless diet may help this, and as you get older, not eating meat can certainly increase your chances of avoiding the disease. However, there is also evidence that it is also possible to avoid common risks that affect longevity, such as smoking, in a collaborative and cooperative manner.
