Nobel prize winner Bernardo Alberto Houssay did some of the earlier work on coconut oil. I could not find the actual study available for free anywahere online, but its referenced on Harvard's website. I've seen commercial sites that refer to this, but no credible site directly quoting it.

From the info what I've gathered on the web, the switch to vegetable oil away from coconut oil has contributed to the rise of diabetes in the US. That and the high fructose corn syrup surge.

Try to buy processed foods that do not have soy or some form of corn in them.
