"The question of the health impacts of coconut oil may have greatest importance for populations like the Philippines, where coconut oil is the most commonly used cooking oil..............Interestingly, data from the Philippine National Nutrition Survey of 2003 revealed a relatively low incidence of hypercholesterolemia, hypertension, stroke and angina in the Bicol Region where diets have high levels of coconut consumption compared to the other regions (17)."

The study above identified hydrogenated oil as the reason some studies show a correlation between heart disease and coconut oil.   Hydrogenation generates trans fatty acids which are now generally agreed to be a huge problem for health generally, and heart health in particular.
