Saturated fats are commonly solid fats like animal and dairy fats and plant fats like nuts, avocado, and coconut oil. Unprocessed coconut oil remains solid up to 76 degrees Fahrenheit. It's impossible to know about a food's health benefits if the food is officially taboo. The nutritional taboo of saturated fat started by one man's highly publicized hypothesis that declared dietary saturated fats as the major source of heart disease. His name was Ancel Keys, a physiologist and researcher with the University of Minnesota who conducted a massive international study called the Seven Countries Study. Even then, several scientists questioned Keys' epidemiological evidence that led to his hypothetical conclusions. Ancel Keys made the cover of Time Magazine in 1961, the year when he managed to persuade the American Heart Association (AHA) to issue dietary guidelines that excluded saturated fats. In their place came refined carbohydrates and processed vegetable oils. The false causation of heart disease from saturated fats true cause is currently scientifically disputed by iconoclastic cardiologists such as Dr. Dwight Lundell, Dr. Stephan Sinatra, Dr. Ron Rosedale, Britain's Dr. Aseem Malholtra and other cardiologists and health experts who have been courageous enough to publicly speak against the unproven theory of the saturated fat causing heart disease theory.
