Skepticism, Science & Pseudoscience

I'm not doubting that there's a lot of what generally referred to as "processed foods" which are, let us say, less than nutritionally optimal.

However, there are all sorts of "processes" you can perform when making (or manufacturing) food, and they can't all be bad and equally bad. After all, baking is a process. Roasting is a process. Slicing, dicing, grinding, fermenting, boiling, broiling... those are all processes. Is a process good because your grandma's grandma could have done it in her kitchen, but bad because was invented sometime after 1900 and is done in a large vat?

If there was any solid research here, you'd think they could be specific about what which particular processes are detrimental, in what way and to what degree.

By the way, I am aware of how ingredients are listed in order by weight, but still makes it hard to figure out for something like my yogurt what portion of the 15 grams of sugar was already in the yogurt and in the fruit added to the yogurt before additional sweeteners were added. I can at least figure out by looking at a container of plain yogurt that it has much less total sugar, about 4 grams for an equal serving size.
