Study: Vegetarians live longer than non-vegetarians
"Vegetarian diets are associated with a lower death rate [...]", a study by the Loma Linda University in California found among around 70,000 participants. It was published a few days ago in the medical journal JAMA and sheds a clear light on the advantages of vegetarian and vegan nutrition. The end result: 12 percent fewer deaths and 19 percent fewer heart diseases such as heart attacks on the vegetarian side. According to the results, men in particular benefit from a meatless diet.
Vegetarian diet lowers death rate "Professional interest in vegetarian nutrition has reached unforeseen levels, but knowledge about vegetarian diets and their impact on human life is far from complete," said Dr. Joan Sabate of Loma Linda University earlier this year. With a new study led by Dr. Michael Orlich is now helping the California University to fill the existing knowledge gaps. A total of 73,308 participants were divided into five groups: non-vegetarians; Semi-vegetarians who reduced their meat consumption; Pesco vegetarians who eat seafood; Ovo-lacto vegetarians who eat dairy products and eggs and vegans who do not consume animal products at all.
In particular, the mortality of the study participants was examined. During the observation period, 2,570 of the 73,308 participants died, with the death rate of the vegetarians being 12 percent below the mortality rate of the non-vegetarians. Some chronic diseases were also less common in the vegetarian test groups, including heart disease, kidney failure and diabetes. According to the study results, the greatest beneficiaries are men. Although the vegetarian and vegan study participants were better educated, exercised more and drank less alcohol, Orlich is certain: "When people make decisions about their diet and weigh up their options, they should also consider the results of this study in their decision."
Further studies confirm the findings of the Loma Linda University. Similar results were also shown in other research work. A long-term study by the German Cancer Research Center found in 2010 that the mortality rate for a meat-free diet decreased significantly compared to the German population as a whole - by an average of 30 percent for women and even for an average of 50 percent for men. British researchers from the University of Oxford published an article in the American Journal of Clinical Nutrition in January 2013, presenting equally interesting study results. They came to the conclusion that vegetarians suffer from heart diseases far less frequently than non-vegetarians. The investigation was based on data from around 45,000 patients.
It is largely unclear why men in particular benefit from a meat-free diet. It is believed that women generally pay more attention to their health. The positive effects would therefore be less evident in women than in men. In order to get to the bottom of this question, more gender-specific studies will be undertaken in the future. And the effects on cancer will also be examined in more detail. It remains unclear, however, whether the study results depend on the already healthier lifestyle of vegetarians and vegans. Critics of the above studies repeatedly insist on this connection. Which recipes can also be prepared without meat is revealed by sites such as www.vegetarian-rezepte.com. (lb)
