Many had been led to believe that soya bean oil, canola oil, sunflower
oil etc. are healthy and great for the heart. This deception started
way back in the 80s when the soya-bean oil lobby made a presentation
to the then FDA and AHA and argued that coconut oil was unhealthy. The
incidences of heart diseases was on the rise and no one really knew
what was the cause of this increases. Cholesterol was blamed even
when evidences at that time did not support it. Keyes argument that
dietary saturated fat was the cause of it gained currency when
evidences were scant and dubious.
