Excellent article. I wrote a whole chapter about this in my book 'This Is Your Quest" - https://authorjoannereed.net/the-book/. I made reference to the book "Pure, White and Deadly" by John Yudkin. The whole premise of the book was that it was sugar and not fat which that posed teh greatest danger to our health. I also mentioned Ian Leslie wrote an article in 2016 titled "Sugar Conspiracy". Together with the book "The Big Fat Surprise" by Nina Teicholz.
