Coconut is not an “exotic” food like in the Western World, primarily consumed by health conscious people.
In some parts of the World, Coconut is a dietary staple that people have thrived on for many generations.The best example of such a population is the Tokelauans, who live in the South Pacific. 60% of their calories are from Coconuts and are the biggest consumers of saturated fat in the world.These people are in excellent health, with no evidence of heart disease.
In the year 1958, an American scientist called Ancel Keys started a study called the Seven Countries Study, which examined the association between diet and cardiovascular disease in different countries.
The study revealed that the countries where fat consumption was the highest had the most heart disease, supporting the idea that dietary fat caused heart disease.
The problem is that he intentionally left out:
Basically, he only used data from the countries that supported his theory, a process known as cherry picking.
This highly flawed observational study gained massive media attention and had a major influence on the dietary guidelines of the next few decades.
These guidelines received massive criticism at the time.
The whole guidelines were based on observational studies made by biased scientists and had nothing even closely resembling scientific proof to back them up.
