Teicholz on the dietary guidelines: “At least do no harm”

In 60,000 participants, or more than 60,000 participants they found, they could find no– in none of them in many systematic reviews of literature could they ever find any effect of saturated fats on cardiovascular disease, cardiovascular mortality or total mortality.

And I want to say that these are all trials in which saturated fats are swapped for vegetable oils. There was some talk about vegetable oils yesterday and how they’re almost like butter, but in these– these are trials where they actually looked at the different– they took out some–

half the people had hamburger, regular meat, regular milk, regular cheese and the other half had soy filled milk, soy filled cheese, soy bean oil on their salads, and at the end of those trials they could not find any difference in cardiovascular mortality for the most part and in some there was an increase in cardiovascular mortality the more the men lowered their cholesterol.

But what they did find was that the people on the vegetable oil diets died at much higher rates of cancer, consistently, and that’s a clinical trial. So, you could say that those vegetable oils caused cancer, which is just one of the things that doesn’t get talked about much when we talk about vegetable oils.
So, what is the evidence for the dietary patterns? It is all epidemiological. It all rests on epidemiology, and it is contradicted by the clinical trial evidence.
