Reading these [diet] books and consulting some of the original studies has been a sobering experience. The successful attempt to reduce fat in the diet of Americans and others around the world has been a global, uncontrolled experiment, which like all experiments may well have led to bad outcomes. What’s more, it has initiated a further set of uncontrolled global experiments that are continuing. Teicholz has done a remarkable job in analysing how weak science, strong personalities, vested interests, and political expediency have initiated this series of experiments. She quotes Nancy Harmon Jenkins, author of the Mediterranean Diet Cookbook and one of the founders of Oldways, as saying, “The food world is particularly prey to consumption, because so much money is made on food and so much depends on talk and especially the opinions of experts.” It’s surely time for better science and for humility among experts.
