The elephant in the room of course is the call, unsurprisingly, to reduce consumption of red and processed meats. However like this 2019 meta-analysis of randomized controlled trials warns, observational studies are routinely open to bias, and difficult to control for all the confounding factors which can come in an almost infinitely-variable number. In it, the researchers at the Cochrane Centers in Spain and Poland found that of all the randomized, placebo-controlled trials done on red and processed meat consumption, there\u2019s no health benefit to be gained for limiting its consumption.<\/p>

Furthermore, one could look at the prevalence of nutritional deficiencies of vitamin B12, choline, and iron in America, nutrients found in large amounts in red meat, and reason that since this new longevity finding didn\u2019t control for nutrient deficiencies, red meat consumption should be maintained along with proper exercise (or less sitting).<\/p>

While the studies used control for exercise, it\u2019s not clear the degree of exercise that is counted, nor is it clear the hours spent sitting in a day, which is sometimes more important than time spent exercising. Therefore, like other huge dietary studies, they should be taken with a pinch of salt.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
