Some environments, people, foods, etc suit us better than others, and that's as it should be. Our inclinations teach us about ourselves, and they have a way of changing over time, as we change. Feeling uncomfortable with something that once pleased us, or someone, demonstrates our growth. And hopefully we grow towards better health and not away from it.
Life is not stagnant. It is always evolving like a spiral. The thing to consider is whether we are spiraling up or down or out of control, and be willing to make different choices if it's not heading in the direction we want to go.
As I become healthier, I am attracted to healthier things.
