I’m going to be a bit sympathetic to the AHA. It’s a thing left over from business school, and I don’t want this to be confused with an actual defense of their position. It’s lifted from Gary Taubes.
They bought Ancel Keyes and rejected John Yudkin. That was 50 years ago, give or take. Ever since then, they have pushed the Keyes theory of CICO/6-10 servings of grain, sugar in place of fat for heart health. They have hammered that home and spent billions searching for the data to back it up. They went with the US government, the American Diabetes Association, and more.
Consider how you, as president of the AHA would approach the task of reversing 50 years of advice that has lead to diabetes going to epidemic status, adult onset diabetes being seen in children and being rebranded as type 2, metabolic syndrome exploding, obesity going up, and more. And they have been recommending the precise prescription to get you there, against the accepted wisdom of the the years immediately ahead of the recommendation.
I don’t think you can have a big press conference and say, "you know what, we screwed the pooch… sorry that we made diabetes a global epidemic. Sorry your dad died from heart disease. Sorry the statin industry is a billion dollar enterprise and we pushed the recommendations to mess up cholesterol to where you’d need statins. Sorry. But trust us now, we have it right this time.’
It’s gonna take the AHA a loooong time to come around to ketogenic dieting without shredding their reputation. Should their reputation be shredded, absolutely. But with a little shift of POV, you can see as how the AHA doesn’t see it that way.
That said, they should probably fold tents and reform under a new banner, and push the actual facts. Of course, I should also be a Men’s Health cover model and independently wealthy.
