For heaven's sake, what's important is to KNOW THYSELF. Everything that exists in this material world is just what it is. It means nothing unless you give it meaning. So why waste all of your awareness listing off what's good and what's bad, what to avoid and what to run to... when the plot is inward, to who you truly are? When you know yourself, you'll quickly realize that nothing you take in materially has much importance at all. And more to the point, if there were anything inherently incompatible with the truth of you in the material form/food you take in, your consciousness is sufficient to put it to rest without so much as a "what was that?".
And from then on, you would not feel drawn to that food or drink or thing, nor would you "accidentally" run into it in any unpleasant manner... simply because your relationship in self is aright and your experience has filled in a previous gap, about what is precisely right for you in this world. One experience with something is all it takes... if you know how to trust your Self and your form. IT will tell you what to do and what to avoid, you do not need to carry a list in the head. The whole beingness will resonate to or away from what is right for you... if you trust it. Mentally deciding what's what for you is a great way to display a lack of trust in your beingness, btw.
So that is where to place importance... on the relationship you have to your greater self. You must know how to feel the aversion your body may feel toward something, or it's indifference, or it's craving. Forget about mentally ticking off things in your mind about life in material form. It will never free you or guide you properly. It can't. It's not designed to.
Your body is not your enemy, it's perhaps your greatest ally in this journey. You don't need to learn how to handle your form by using your head, you don't need to control it or mistrust it or treat it like an object. It is built of the finest consciousness, designed to guide you through the material world. Learn to listen to its wisdom, not to someone else's. It speaks in feelings. Learn to pay attention to that, it's your own wisdom, available in every moment.
Let go of paying attention to someone else's possible clues or what seems to work for them, but rather focus on what your own beingness tells you in every moment. You learn to hear it by focusing on your relationship with the greater you (which operates tangibly through your heart and body, bypassing the mind with purpose). You'll know what you need to know through that practice, and the rest... is just the "stuff" of other people still not having found their right relationship in self, trying on mental ideas of reality that seem to work for a while...
There are few things to be concerned with at the food intake level, and those only by genetic matrix of birth (allergies, for instance), until you grow beyond it (in your consciousness, btw, which is what changes your form).
Talk about diverting consciousness! This world is uber focused on so much that has so little value or import in truth. The best use of your mind is to ask questions of your greater self, witness life with intent to discover, and to make decisions. Mundane decisions of course, as well as the decision to listen to the body over someone else's input, and also the decision to defer to a higher awareness than the mind itself carries here, by choosing to step back from being in charge of your divinity and instead listen/learn.
Know your divinity. It is not in the human mind. It is in the wholeness of your beingness. Discovering this, becoming intimate with this... is what brings you higher in frequency. Not what food you eat. And focusing on foods and other external matters tells a great deal about what frequency you're at... so consider that. Our divinity, the truth of our being, has an inherent trust in life and in our beingness. It inherently trusts its form, as well (it created it! From full awareness and harmony, btw)... to perform as designed by the Divine Self. This is why there have been so many esoteric messages about witnessing. If you truly pay attention... watch and listen... to your own being as it experiences anything here... you will discover what you need to know. About anything and everything. If you can get out of your head, that is.
