@Sasha Cookbooks don’t teach one with OCD to be more cautious; they just list what kills common pathogens for specific foods.
Often we get sick from people sharing germs as opposed to improperly prepared food, but it is still good to know what temperature at which to cook certain meats. Doing that will not prevent someone from catching a stomach bug.
Just having an initial knowledge base is not the same as reassurance. Yes, with Google, it can often turn into a rabbit hole of reassurance seeking, which is why I specifically suggested against it. Doctors in live sessions on this site have said it is ok to ask a question ONE TIME to know something; however, that is limited to one time so that it does not spiral.
While all of us here are dealing with OCD in some capacity, and while OCD is both illogical and not to be reasoned with, even those with OCD have different minds and thought streams. For example, in general, a study showed that those with more creative minds respond better to setting watched earlier in order to not be late. For some people, OCD or not, this method works for those who are better able to “trick” themselves, whereas for others, they just know how far off they have set their watch and thus they automatically correct the time on their watch in their head.
All of this is why I warned that one should only try this method if in the state of mind to be able to fight the spiral of reassurance seeking, and that even then, while just limited knowledge can help many, it may not be the best for all. This is also why I suggested the best thing to do would be to work with a therapist on ERP for emetophobia.
