"For example, inuit populations also display generally low obesity and risks of heart attack, stroke, diabetes etc - while consuming almost the opposite of a Mediterranean diet or of plant heavy diets."

The studies backing up specific diets are not population level, but rather specific study groups. And yes, there are other healthy diets too.
