Since the late 1970s, the general public has been under “heart health diet” propaganda that is completely, 180 degrees wrong.
Little by little, new studies have been coming out bursting these guidelines, proving almost every aspect of it ridiculous.
Interestingly, one of the best studies on this matter was conducted in the 1960s and 1970s, but for some mysterious reason was only published recently in the BMJ (the British Medical Journal).
Apparently, the fat that has been forced down your throat for 30 years is deadly and should be replaced with the one you wanted all along.
Between 1968 and 1973, researchers in Minnesota (most of whom have since died) collected dietary information, medical examinations, and autopsies of 9,423 people who were institutionalized in six mental hospitals and one nursing home.
This meant that their diet was recorded very accurately and researchers didn’t rely on subject self-report as most studies do.
The participants were divided into two dietary groups.
The intervention group reduced its animal fat (saturated fat) intake by 50 percent and increased its plant oil (linoleic acid) intake by more than 280 percent.
The control group maintained its saturated fat levels from before the study and increased its linoleic acid intake by 38 percent.
The people remained on these diets for between one and four years.
The researchers expected the study to prove that the intervention group with the massive amounts of plant oil and reduced animal fat would have lower cholesterol.
And they were right. The intervention group had approximately 13 percent lower cholesterol than the animal fat group had, which is pretty much consistent with the contemporary mainstream advice.
But, oddly, people in the plant oil group with the lower cholesterol were more likely to die of all causes than those in the animal fat group with the higher cholesterol.
Even more confusingly, the levels of atherosclerosis (clogged arteries) in the two groups were approximately identical.
In other words, higher cholesterol levels were associated with better heart health and longer lives, and lower cholesterol levels with poorer heart health and shorter lives.
