>What's wrong with metal surfaces? Plastic is xenoestrogenic cancer, of course, but metal should be fine. Do you refuse to eat anything that has touched anything but flesh, wood and ceramic? What do you even eat?
The problem I see is where there is risk of excessive leaching of heavy metals or toxins into the food. This is usually an issue when food is acidic. For example, cooking in stainless steel is fairly safe but an acidic food touching that will probably put a not insignificant amount of nickel (also depends on composition of the stainless steel) into the food. The only acidic foods I eat are citrus fruits/orange juice. My orange juice comes in a cardboard carton. The safe way to process something like tomato sauce is on (lead free) glass surfaces and to perhaps include an alkalizing step such as adding baking soda or calcium carbonate. Obviously it's difficult to avoid all plastics in a food context when shopping at a modern grocery store, but I don't drink from plastic water bottles as they are transported on hot truck trailers and exposed to sunlight at whim to the degree that I expect a decent amount of plastic to have leached into the water from partial melting.
>What do you eat, then?
Many things. Wheat isn't irreplaceable, but as far as carbs go I get a lot from fruit sources and milk, but I do also eat starch sources such as white rice and potatoes. Just about every situation in which a person on a regular Western diet has bread, I am eating dates instead. I am constantly loaded up on minerals via date eating and drinking milk/coffee.
If you like the psychological effects of coffee, it might be because of its ability to antagonize the effects of opioids in the diet:

>We report here that instant coffee powders from a variety of manufacturers compete with tritiated naloxone for binding to opiate receptors in the rat brain membrane preparations, with no significant difference between normal and decaffeinated coffee. The receptor binding activity resembles that seen with opiate antagonists, in that there was no change in the half-maximal effective dose (ED50) in the presence of 100 mM Na+; on bioassay, the activity was similarly shown to be antagonistic and specific for opiate-induced inhibition of twitch.

>These results suggest that the previously reported anti-opioid activity of instant coffee is caused primarily by the presence of 4-CQL, and to lesser extent by other cinnamoyl-1,5-quinides.
