By the 1970s, each individual step of this chain from fat to cholesterol to heart disease had been demonstrated fatty acid analysis beyond reasonable doubt, but the veracity of the chain as a whole fatty acid analysis has never been proven. In other words, despite decades of research, it is still a debatable proposition whether the consumption of saturated fats above recommended levels (step one in the chain) by anyone who's not already at high risk of heart disease will increase the likelihood of untimely death (outcome three).
