Avoid eating impure animals?

[Noahide Q]

The other justification that an individual Gentile may have for not eating a particular type of animal, is if he dislikes the taste, or if it nauseates him, or he's disgusted by it. In regard to any food, a Gentile can choose on any particular day to eat what he enjoys, and not eat what doesn't enjoy, on account of his personal tastes and appetites at that time.

I really appreciate the clarifications provided above. Especially regarding a Gentile being allowed to voluntarily restrict himself to only eating Jewish-certified kosher meat. Beyond this, I have some further queries that have been gnawing away at me:

Would a Gentile be justified in being disgusted to eat a particular type of animal, just because Hashem has singled the animal out as something to be avoided for Jews?

What I mean by this is that the Gentile would understand that they are not forbidden from eating the animal, only Jews are, but the mere fact that Jews have been advised by G-d to refrain causes a stigma in the mind of the Gentile against eating the animal. In his mind the gentile can not psychologically let go of this stigma being attached to eating it because of a negative implication that has indirectly been inferred. It's not that the Gentile craves eating the animal, and is only holding themselves back from doing so because they mistakenly think they are forbidden to, but the desire for eating it has been taken away by how it has been mentioned in the Torah. Is the solution that the Gentile should try cure themselves of this negative impression or they can continue to avoid those foods because of it? The Gentile would not think anything less of another Noahide for whom such a negative impression/distaste has not risen to the level that they avoid eating.

Secondly, there is scientific research that shows potentially hazardous health effects of eating non-kosher animals e.g mercury other contaminants accumulated in shellfish, trichinosis in pork. Certain websites and articles have specifically been created by Jews & non-Jews to highlight those aspects. If a Gentile finds this research convincing they may assume, perhaps wrongly, that there are secondary reasons (other than the primary spiritual reason) having to do with physical health that could equally apply to Jews & non-Jews, as shown in the research. However, I understand that if they are deciding based on health alone they should only make a decision with regards to this based on an objective evaluation of the scientific evidence. In such manner I understand that they may find a justification to avoid the non-kosher food for health reasons. However, this Gentile should not look negatively upon another Noahide if they are unconvinced by the scientific evidence, or find the pleasure of eating the non-kosher animal outweighs the health concern.

Would a Gentile be misguided in going out of their way to find health reasons to justify not eating non-kosher foods, in particular? Even if the original intention was misguided, if they are convinced they found a risk to health in eating the animal they can choose to avoid eating the animal for health? Would this be a form of hypocrisy though if the Gentile does not apply the same degree of scrutiny and research into the health risks of certain kosher foods, especially if they are not generally keeping a healthy regime by avoiding foods high in fat or sugar? I understand it could all be captured under the prohibition of self-harm 'But your blood of your [own] souls I will demand' Genesis 9:5

Would really appreciate your guidance on this.
