The favorite cudgel of leftist climate change fear mongers is the appeal to authority, as in that there is “a scientific consensus” that the earth is warming and that changes over the last century are due to human activity. The problem with appeals to authority on extremely broad scientific topics is that they are not subject to easy proof by experimentation, and are quite often wrong. Here’s a list of ten popular theories ultimately proven false, and it omits some major howlers, like therapeutically bleeding people or the geocentric theory of the solar system. Now we can add to that list the “scientific consensus” that diets rich in processed foods and fats lead to heart disease. This idea, which has dominated medical thinking for at least the last half-century, and led to all manner of government policy making, regulation and just plain tsuris over finishing the brisket, is now in doubt.
New studies of pre-modern humans, dating back many millennia, demonstrate that arteriosclerosis (the hardening of the arterial blood vessels that causes blockages and heart attacks) afflicted people who (by necessity and not choice) followed that most rigid of diet and exercise regimens — hunting and gathering. The mummified remains of Neolithic era humans from around the globe demonstrate that arterial disease was about as commonplace in those ancient populations as it is today. Despite the fact that these people had diets low on saturated fats, high in proteins, vegetables and fruits, and engaged in regular and strenuous exercise, they still suffered from heart disease as they aged at about the same rates as modern humans.
