> It is really a wholesome plant extract instead of something chemists have invented which leads me to have confidence in its (so far as we know) lack of carcinogenicity. This sounds like the naturalistic fallacy [1]. A naturally occurring substance is not automatically less carcinogen, or harmful, than a manufactured one. Coffee is associated with elevated risk for bladder cancer. Cycad trees are known to be highly…
I don't think it's a fallacy to conclude generally that consuming plants which coevolved with humans is safer than consuming chemicals which are completely exogenous to any stage of the human body's development. It would be a fallacy to suggest that one group or the other were unconditionally safer, but I find no dilemma in generalizing that the human body is more capable of processing plant-based substances. Just li…
An optimal organism doesn't imply an optimal environment.
fitness(org, food) = -2 org^2 + org * food + 7
If evolution had optimized fitness by adjusting "org" while keeping "food" constant, that wouldn't imply holding "org" constant and changing "food" wouldn't yield improvement.Evolution doesn't optimize the environment for the organism. Evolution performs stochastic gradient descent, improving the organism for the environment, which can easily get stuck at global optima. More importantly, it improves the organism for the environment/food/etc. The idea that the food is optimal for the organism gets the improvement mechanism backward.
