macroPsychotic,
They say that titanium
http://www.chem.ed.ac.uk/chemcon/metals/titanium.htm is non-reactive to food but that it is bonded to other metals (like aluminum) via hard-anodizing.
How thick the plating is and how long it would take to wear through, I guess might be determining factors, regarding how safe it is to use.
More emphasis in the cooking classes that I attend focus on dense heavy pots that help to bring warmth and energy into food.
How lightweight pots are for camping or travel does not seem to be much of a concern.
Most macros I know are more interested in living near natural surrounding than going off on camping trips, backpacking in the wilds that would need lightweight equipment.
Speaking of unusual places for macrobiotic people to cook and feed themselves, how do you suppose an astronaut who decided to follow a macrobiotic diet, would cook and prepare foods for him/herself in a gravity-free environment?
Can astronauts be macrobiotic or is the diet, planet bound?
Thank you, very much.
