my sister is a vegetarian and has been for what roughly 10 yrs or something, but she's not an empath. I think it was animal cruelty that made her switch.
as far as intuition is concerned I don't think it does help, least ive never experienced anything. but it should be a personal choice if you wanted to take care of lifestyle and general well-being.
there is on a religious note, I'm not sure how it would be for non religious individuals, I used to recite a particular prayer song, when cooking, I always heard stories of how it increased knowledge and wisdom, and these people would swear by it, it was 2nd nature to me anyway so I did it regularly, and because I was empath, I saw significant spike in my daughters intellect, she's naturally brainy anyway but I was taken aback by some of the things she would converse on..
people could make theyre own little prayers I suppose when preparing food do have it blessed and project energies and see how it goes.. sorry if that was off topic..
