Coffee is a weird thing. Until 5 years ago, I didn't even like coffee. Now I drink several cups a day. I don't know what to think about this. On the one hand, I like it and I can't see it doing much harm. On the other hand, caffeine is bad and I have a number of friends who avoid caffeine completely.
I don't know enough to make an informed decision about coffee so I just carry on drinking it quite thoughtlessly, really. If I look for more information, there is a chance I might feel bad about caffeine and want to stop drink it even though I would miss the habit. I think it is true for many people. Not for coffee, but definitely for many other things where the real choice we make is to stay unknowing. There is a risk inherent with knowing more, you might change your mind, change your behavior, reassess your existing knowledge. Add to that the cost (time) of gathering information and you get a pretty poor risk-benefit analysis. If the benefits of doing this (mitigate potential harmful side effects of caffeine) seems low, the choice to stay unknowing is a logical choice to make.
This is such a stupid thing to do, though. It means decisions are based on guesses and perceptions rather than real facts and information. This can be applied to so many things and the obvious discussion that comes into mind is climate change and sustainability. People have very strong views about this, both pro's and con's. But how many people could actually say that they are informed about the state of the planet, for example? That is a whole different discussion and one that is just remotely related to LCHF so we'll leave it at there for now.
But think about it. Are your food choices based on intelligent decisions or unknowing guesses?
