I found this interesting image because a lot of people eat and drink certain things because of a “just because”. Example, some people can say they drink their coffee or tea with Stevia sugar because it comes from a plant, a herb. Therefore plants are natural. That excuse would be like saying it’s okay to eat other plants besides vegetables including, Toxicodendron radicans (Poisen Ivy, oaks, etc.)! I’m not saying that you have to be illiterate to do such a thing but this is what the comment sounds like. If something is natural it doesn’t necessarily mean it’s good for you. Stevia has no physical sign of danger just like poison Ivy. However, the only thing we know is that if we touch the Ivy we get a rash. Well the same applies to everything in life just because it doesn’t look dangerous and you think it’s good or other people tell you it is think again before you try it. Heuristic can lead to shallow thinking and making harmful decisions.
