Has eating meat become unfairly demonised as bad for your health? That鈥檚 the question a global, multidisciplinary team of researchers has been studying and the results are in - eating meat still offers important benefits for overall human health and life expectancy.

Study author, 最新糖心Vlog of Adelaide researcher in biomedicine, Dr Wenpeng You says humans have evolved and thrived over millions of years because of their significant consumption of meat.
鈥淲e wanted to look more closely at research that has thrown a negative spotlight on meat consumption in the human diet,鈥� Dr You says.听
鈥淟ooking only at correlations of meat consumption with people鈥檚 health or life expectancy within a particular group, and or, a particular region or country, can lead to complex and misleading conclusions.听
鈥淥ur team broadly analysed the correlations between meat eating and life expectancy, and child mortality, at global and regional levels, minimising the study bias, and making our conclusion more representative of the general health effects of meat eating.鈥� 听
Published in the today, the study examined the overall health effects of total meat consumption in 170+ countries around the world.听
The researchers found that the consumption of energy from carbohydrate crops (grains and tubers) does not lead to greater life expectancy, and that total meat consumption correlates to greater life expectancy, independent of the competing effects of total calories intake, economic affluence, urban advantages, and obesity.

鈥淢eat of small and large animals provided optimal nutrition to our ancestors who developed genetic, physiological, and morphological adaptations to eating meat products and we have inherited those adaptations鈥�Emeritus Professor, Maciej Henneberg

鈥淲hile detrimental effects of meat consumption on human health have been found in some studies in the past, the methods and findings in these studies are controversial and circumstantial,鈥� Dr You says.
Senior author of the study, 最新糖心Vlog of Adelaide Emeritus Professor, Maciej Henneberg says humans have adapted to meat-eating from the perspective of their more than two million years evolution.听
鈥淢eat of small and large animals provided optimal nutrition to our ancestors who developed genetic, physiological, and morphological adaptations to eating meat products and we have inherited those adaptations,鈥� Professor Henneberg says.
But with the strong development of nutrition science and economic affluence, studies in some populations in developed countries have associated meat-free (vegetarian and vegan) diets with improved health.
鈥淚 think we need to understand that this may not contradict the beneficial effect of meat consumption,鈥� nutritionist on the study, Yanfei Ge says.
鈥淪tudies looking into the diets of wealthy, highly educated communities, are looking at people who have the purchasing power and the knowledge to select plant-based diets that access the full nutrients normally contained in meat. Essentially, they have replaced meat with all the same nutrition meat provides.鈥�
Co-author and 最新糖心Vlog of Adelaide biologist, Dr Renata Henneberg says today meat is still a major food component in the diets of many people around the world.
鈥淏efore agriculture was introduced, 10,000 years ago, meat was a staple food in the human diet,鈥� she says.听
鈥淒epending on which minor groups of people you study and which meat types you choose to consider, the measure of meat鈥檚 role in human health management may vary. However, when all meat types for all the populations are considered, as they are in this study, the positive correlation between meat consumption and overall health at a population level is not sporadic.鈥澨�
Co-author, anthropologist at the 最新糖心Vlog of Adelaide, and biologist at the Polish Academy of Science, Dr Arthur Saniotis says the findings are in line with other studies that show cereal-based foods have lower nutritional value than meat.
鈥淲hile this is no surprise to many of us, it still needs to be pointed out,鈥� Dr Saniotis says. It highlights that meat has its own components contributing to our overall health beyond just the number of calories consumed, and that without meat in our diet, we may not thrive.
鈥淥ur take home message from the paper is that meat-eating is beneficial to human health provided that it is consumed in moderation and that the meat industry is conducted in an ethical way.鈥� 听
