I've just started using the coconut oils a bit as I'm decreasing carb content. I reckon I feel better (more energetic) after consuming some oils, but I'm reminded of the Simpson's episode where the townfolk turn a truck over looking for placebos.
I can see that the MCTs seem to be beneficial, but where in the paleolithic landscape were the MCTs coming from, so that our body could use them? Was there a food source (no longer around now) that our forebears were getting the MCTs from, or just lots of coconuts? Or is it too much of a stretch to make up an evolutionary story up (other than those who processed MCTs had an advantage and thus passed on their genes a bit more on average)?
