Been thinking... People eat cold pasta and cold potato salad. Jane Eyre ate cold porridge that would otherwise have been given to the pigs, and was glad of it. After all, cold food is just as nourishing as hot food, if not always as pleasant to eat. But, who knows, maybe some people like cold chips, and how many is a few?
So, I'm thinking, that a 'few' cold chips for lunch might be fine actually, if that's what you like. If I liked cold chips, I might well have them for lunch sometimes, just as I sometimes have and apple and a slab of chocolate (good (and I mean good) mountain food). I think that because we can be so choosy, we are getting too picky and too critical of what is in fact good food.
How do I know potatos are good food? Well, Irish peasants, including some of my ancestors, lived on them as a staple for generations and not only survived but increased their survival rate. That's the bottom line – survival to reproduce offspring that also survives to reproduce. How life works.
