We have been wondering for decades if being vegetarian prevents cancer. We already have a very clear answer

There is a endless diets in different parts of the world, conditioned largely by local society and culture, such as in Spain, where the Mediterranean dietwhich is varied. But the focus of the debate is on what is the best diet to maintain good health in the long term. And here the vegetarian diet has a lot to say. Giving answers. For years, we have known that reducing our consumption of processed meat is beneficial for our health, but a new macro study led by the University of Oxford has put compelling data on the table about how dietary choice directly impacts the risk of developing different types of cancer. The work published in the magazine British Journal of Cancer is consolidated as the further analysis performed to date on this topic. And it is no wonder, since researchers have been able to analyze the histories of 1.8 million women and men who participated in nine prospective studies across three continents. A shield. Until now, previous studies they were already pointing that vegetarians had a lower oncological risk, but there was not the necessary statistical power to refine the data and make this categorical statement. But this study has come to change this, since researchers reveal that vegetarians have a significantly lower risk of suffering from five types of cancer compared to people who eat meat regularly. Results. Obviously, there are many other factors that influence this matter such as weight or lifestyle, but even adjusting the data, a clear result has been seen, which is summarized in the following risk reductions: 31% lower risk of suffering from multiple myeloma. 28% lower risk of kidney cancer. 21% lower risk of pancreatic cancer. 12% lower risk of pancreatic cancer. 9% lower risk of breast cancer. But the curious thing about these data is that for ten other types of cancer studied, such as lung cancer in non-smokers, science has not found a significant difference. And this opens the door to seeing why this diet is so specific for specific cancers. The small print. Not everything is so positive with this diet, since the study has shown that vegetarians have almost double the risk of developing esophageal cancer compared to people who eat meat in their diet. Because? According to researchers, the benefits of a vegetarian diet in cancer are explained by the greater intake of fruits, vegetables, fiber and the absence of processed meats. But the fact that they have a higher risk of having esophageal cancer is related to the nutritional deficiencies that vegetarians may have. And the lack of certain exclusive or more present nutrients in foods of animal origin could be weakening the natural defenses of this tissue. The rest of the diets. In addition to the war that may exist between meat and vegetables, researchers wanted to go further to look at the rest of the diet. In this case, the pescetarianswho do not consume meat, but do consume fish and seafood, had a lower risk of developing breast, kidney and colon cancer. But when we talk about vegansis where there are certain important nuances, since it has been seen that they have a higher risk of suffering from colorectal cancer. However, the researchers themselves point out that there are still not enough statistical cases to accurately evaluate the impact of veganism on rarer cancers. The recommendations. Given this study, everything that had been done in oncology is maintained, since the norm is to prioritize whole grains, legumes, fruits and vegetables in the diet, limiting the consumption of red and processed meats. Although logically always ensuring that all nutritional needs are met and following medical advice. Images | amin ramezani In Xataka | Having a beer or a wine at 65 seems like a harmless indulgence. We have more and more evidence to the contrary.

We believed that a vegetarian diet guaranteed longevity. In extreme old age, the data says just the opposite

There are many positions in nutrition about what food It is the one that will give us a better old age. One of the positions that you have surely heard is the need to reduce meat consumption to prioritize vegetables for everyone the benefits that they contribute. But now science is pointing out that what works at age 40 may not be ideal at age 90. The change of course. A published study this same year in The American Journal of Clinical Nutrition has shaken the hornet’s nest of gerontology after analyzing thousands of elderly people. The conclusion they have drawn is that among those over 80 years of age, those who consume meat are more likely to become centenarians than strict vegetarians. But before you rush to cancel your salad order, read the fine print: the key is not the meat per sebut weight, fragility and the fight against muscle loss. The data. In order to reach this conclusion, the study analyzed data from a longevity survey in the Chinese population carried out between 1998 and 2018. In total, the researchers followed 5,203 participants who were over 80 years old, classifying them based on omnivores or vegetariansincluding vegans and ovolactovegetarians. The results. Adjusting for age, gender, and baseline health, the study yielded a surprising finding: vegetarian diets were associated with a 25% lower chance of reaching age 100 compared to omnivorous diets. A correlation that was statistically significant mainly in the elderly who were already thin. Thinness. This is a really important point to present one of the nuances of this research. And the advantage of carnivores disappears in people who have a weight within the established normality. Thus, the negative association between being vegetarian and extreme longevity was observed almost exclusively in participants with a BMI lower than 18.5. That is, extreme thinness. This reinforces what is sometimes known in medicine as the “paradox of obesity in old age“. While in youth overweight is a risk factor for almost everything, in extreme old age, having energy reserves and muscle mass is life insurance. This is why the authors of the study emphasize that the consumption of foods of animal origin seems to act as a protective factor against malnutrition and frailty in these vulnerable individuals. Because. The biological explanation that suggests that meat is good in old age is based on the constant fight against degradation. One of these events is the dreaded sarcopeniawhich occurs when the natural loss of muscle mass accelerates over time. One of the objectives here, as we have repeated many times, is to maintain muscle with highly bioavailable proteins that are in meat, eggs and milk. In addition to this, the study suggests that strict vegetarians, especially thin ones, may not be ingesting enough total calories to maintain their physiology in stressful situations. And it is not crazy now, but previous studies have already pointed out that, although restricting meat reduces mortality in young people and middle adults, this effect was reversed in old age. They don’t cast a shadow. Logically, this study does not negate the many benefits of a plant-based diet for the general population. In fact, there are studies that suggest that for the vast majority of the population the priority continues to be preventing serious chronic diseases such as diabetes. However, this work suggests that nutrition must be dynamic, since the requirement in middle age is not the same as in the last years of life.
