The most important thing is approaching other points of view with an open mind, with epistemic humility , that is, knowing that something of what you think can be wrong, even if, from the inside, everything feels right.
On the object level:
Carbohydrates can be: fruit/whole grains/normal bread/normal pasta or North American crazy industrial snacks and “sugar-cereals” and “sugar-bread”. The first one is good, the second one is bad.
No idea about optimal salt levels, just a note on your language: “potentially deadly” is too vague to have a useful discussion. Crossing the road is “potentially deadly” for some definitions of “potentially deadly”. Try to quantify the risk instead, at least approximately.
For facemasks, a surgical mask that you re-use for several day, without cutting your beard (beard makes it impossible to have a perfect fit), with a random size, removing it constantly to eat and drink, of course it is going to work badly. If you wear a serious P100 masks, of appropriate shape and size, with no beard (cut down to zero with a high quality manual razor) and never remove it, of course it is going to work, it is basic physics at that point. If it is a good idea to wear it, considering costs and benefits, is another discussion.
Please be really careful about psychoactive substances, they might have long term effects that are little known because they are little studied. (This last statement is based on random stuff read on the internet, take with a grain of salt).
