In this extremely popular and numerously mirrored lecture, Dr. Michael Greger presents "proofs" that humans should not consume dairy milk and meat at all, because it is destructive to health in numerous aspects, and by drinking it we effectively shorten our lifespan.
For example, re. cancer, between time 20:58 and 21:30 he asks "how low does our consumption of animal products have to go?" and answers that "only vegans" (not "vegetarians" or "meat-eaters") have significantly lower levels of circulating IGF-1.
Are dairy milk and meat destructive to human health? Does the average human live longer if dairy milk and meat is abstained?
