This is a well established / well known thing especially in communities that perform spiritual exercises. It is acknowledged and used as part of a more complete “spiritual hygiene” routine. Actually it’s part of the rationale behind vegetarianism in those who are attempting to get closer to God and the spiritual realms, practicing ahimsa aside.
Specifically you’ll find these types of ideas even in traditions which reject the study of such realms such as Roman Catholicism, where exorcists have identified through the questioning of the negatively polarised entities that what allows them to gain a foothold in people is anything that makes the victim similar to the spiritual nature of the attacker or plants such a seed. Although they usually focus on sin and various types of trauma, food is another such vector, which is why even when Paul was trying to say Christianity was for everyone including the Gentiles, there were still laws to follow about not eating food that had been sacrificed to idols. It was always about spiritual hygiene so that nothing undesirable to the group or the individual would negatively affect ones attempts at cultivation.
Food is one vector, but it’s only the most direct. Others have spoken on the Fire vs Saint 4 thread about how the subliminals they are running will sometimes bleed over into the lives of those they are close to, such that lovers, partners, housemates etc will manifest aspects of the script after being around them for a time.
Because these sorts of “non physical” influences are a topic usually not spoken about, since most people are focused on more “tangible” things, it’s easy to forget this is something that is happening literally every day, so unless you make a conscious choice to exploit these subtle things in a way that’s going to benefit your evolution, it’s just going to remain an interesting curiosity or something cool to talk about at parties.
