Is there any food you won't give up afterwards?

[Tantravaya]

I worked for quite a few years in the area of diagnosis of food allergies and food intolerances. One of the basis rules that we learnt was if we "need" a particular food in our life, then that food is hurting us in some way. It doesn't matter whether it is a "healthy" or "non-healthy" food (or drink) and it doesn't have to be a food that is craved as such, just always there, in the cupboard or fridge, close by. We don't even have to eat it every day. I have experienced many people shocked to learn that a food touted as good and healthy is actually damaging their health. e.g. tomatoes, broccoli, red meat etc.

The connection between the particular foodstuff and one's health problems is very often not obvious. With food allergies, there is usually an acute response soon after ingestion. With a food intolerance, the offending substance usually contributes to chronic conditions and no links are obvious.

Food is chock a block full of naturally occurring chemicals and sometimes it is the chemical make up of a food that causes difficulty. For example the simple tomato has over 300 chemicals (not including man's addition in the growing process). This is pretty standard for most fruit and vegetables.

So....I am just curious. What food/s do forum members include in their list of food "needs" and are there any foods that you aren't prepared to give up totally? I had one guy say to me that he didn't care whether it killed him but he wasn't going to give up his beef.
