Yes I think food has a major influence on us.

We have to consume life so that we can live in this body so by eating the earth and the things that live on it we are grounded to this body

Likewise the physical will reflect in the spiritual and so what you eat (or should I say not eat) will make you susceptible spiritually.

This is one of the detrimental aspects of the eastern diet with veganism because by only eating plants and no animals you limit yourself to the level of things that only eat plants

But if you eat everything then you're not hardly limited.
