Anthropologists get a large number of factors wrong, mainly because its a field based on theories based on very little evidence, its basically a pseudo science
Archaeology & more recent evidence based fields are far more accurate & far more useful
Check out lloyd pye, he lists the fields & sciences which correctly date & catalog
More than any other field, anthropologists tend to get diet right. Below is a partial list of anthropologists who advocate some form of Paleo Nutrition. It includes Boyd Eaton, who is the scientist that developed the very theory that underpins Paleo nutrition and is both an anthropologist and a radiologist (interestingly, Dr. Kurt Harris is also a radiologist and Paleo diet advocate). Show me a list of achaeologists or scientists from any other field that has as many advocates of Paleo-type nutrition as anthropology and then I'll take your claim seriously. The proof is in the pudding.

I tell people, when it comes to nutrition, you're better off listening to an anthropologist (especially one that specializes in hunter-gatherers or the Paleolithic era--i.e., a Paleoanthropologist) than nutritionists or physicians (who have been indoctrinated in the standard erroneous dogma re: nutrition).
