I don't know all the ways that the rice I ate yesterday affects me. I'm not going to stop eating rice because of this.
Your argument is completely null.
When there's no clear proof of something having a strong negative effect, the rational thing is to assume it doesn't have a strong negative effect.
When something clearly has a strong positive effect, the rational thing is to assume it has a strong positive effect.
And when we decide to do something, we balance positives with negatives. There is nothing in this world that only has positive aspects (the opposite is also true, nothing truly has only negative aspects). We never do something because it's "perfect", we do things that are "good" (more positives than negatives). We live because of water and oxygen but water can drown us and oxygen can burn us.
Your logic is: "a lot of very respectable people (as well as common sense) say that this thing has a positive effect, but I don't know if it has any negative effect, so I just won't do it at all".
That's no logic, it sounds more like spite.
I don't say this lightly, even on the internet, but you act like a horrible person. Please reflect on your behavior and for your sake, I hope you change.
Anyway, goodbye!
Oh, and by the way, there's arsenic in rice. https://www.fda.gov/food/cfsan-risk-safety-assessments/arsen...
