American diet habits had their own Fauci, one Ancel Keys, who through misinformation and dishonesty (anything new here?) forced the FDA to recommend a high carbohydrate/low fat diet that is now responsible for the obesity and diabetes epidemic.
There are numerous excellent books on the subject and as a starter I recommend Gary Taube’s “Why We Get Fat”.
I read most of Taube’s excellent “The Case Against Sugar.” Highly recommended.
“Once again, the brilliant Gary Taubes manages to make a complex scientific subject easy to understand. The Case Against Sugar is a riveting history of ideas, a clear analysis of evidence, and an utterly persuasive argument that sugar is the new tobacco. Taubes methodically explains why sugar—not sloth, not fat—accounts for our unprecedented levels of obesity, cancer, diabetes, and heart disease. Taubes answers every counter-argument as he exposes bad research, reveals conflicts of interest, and explodes myths.” — Gretchen Rubin, author of The Happiness Project
