Also from that white paper…
" The diet-heart hypothesis was first proposed in the 1950s by Ancel Keys, a physiologist at the University of Minnesota with an interest in nutrition [1].
…
Throughout the 1950s, the AHA had resisted giving advice on heart disease prevention, citing a lack of evidence, yet in 1960, Keys was appointed to the group's nutrition committee, and one year later, although no greater evidence could be cited, he had convinced his colleagues to recommend his idea as official AHA policy. Thus, from 1961 on, the AHA recommended that all men (and subsequently women) decrease their consumption of saturated fat, replacing these fats whenever possible with polyunsaturated vegetable oils, as the most promising measure of protection against heart disease [6].
The 1961 AHA advice to limit saturated fat is arguably the single-most influential nutrition policy ever published, as it came to be adopted first by the U.S. government, as official policy for all Americans, in 1980, and then by governments around the world as well as the World Health Organization. It is worth noting that the AHA had a significant conflict of interest, since in 1948, it had received $1.7 million, or about $20 million in today's dollars, from Procter & Gamble (P&G), the makers of Crisco oil [2]. This donation was transformative for the AHA, propelling what was a small group into a national organization; the P&G funds were the 'bang of big bucks' that 'launched' the group, according to the organization's own official history [7]. Vegetable oils such as Crisco have reaped the benefits of this recommendation ever since, as Americans increased their consumption of these oils by nearly 90% from 1970 to 2014 [8]."
