I consider foods that only recently have been able to spring up due to our new, vamped up intense chemistry and the wierd, totally unnatural states we can take things to with our machines (extreme temperatures, pressures, chemicals we could not previously handle, etc.) the 'processed' foods...
I see what you're saying. I think I'm looking at it a bit differently. Hopefully I can explain why I said that it is a highly processed food without sounding like a pedantic b*tch. LOL
I think if the OP is worried about cooking tofu (for the very brief time that tofu needs to be cooked) affecting or destroying the nutrients in soy, then the process of turning a soybean into soy milk and then the soy milk into tofu is at least as worrisome process as cooking the tofu for a few minutes.
Since I took the heating the food to be the common factor that he was worried about having affect the nutrient value of the food - and heat is used in the process of turning the soy beans into tofu ... the damage that the OP is concerned about has already been done.
It may not be as chemically processed as soy protein isolates - but it is pretty processed. There is no resemblance whatever between a soybean and tofu. To some people if you're significantly changing a food from it's natural form you're over processing it.
Not unlike turning wheat into white flour. Again something that has been done for a long time - but definitely counts as a processed food.
I'm not saying that tofu is bad - in fact, I really like tofu. And certainly the process of making tofu is much less chemical and artificial than the process of making soy protein isolate. But soaking dried beans, grinding them, squeezing out the liquid, boiling the liquid, adding a coagulant ... these all significantly change the humble soy bean into tofu. For me while it is perhaps a less harmful process it is still a highly processed food.
75g of edamame has 9 grams of fiber.
75g of tofu has less than .5 gram of fiber
If you're removing that much of the natural material you're processing the food. No matter how old the method.
