> vegetables are good, fruit is (mostly) good, refined grains and free sugars are bad Even those are not really absolutes, because a diet with only those "good" elements will still be worse than a mix including animal proteins. Also, some vegetables are simply bad in excessive quantities (mushrooms, potatoes, etc). The problem we typically have is just over-abundance of everything in our diets. Too much meat is bad, too much vegetables are bad, too much fruit is bad, too much fish is bad, too much dairy is bad. And that's because our bodies evolved to make the most of anything they could digest, since the normal state was scarcity and every little bit helped with survival. Now these finely-tuned "recycling systems" are routinely oversupplied in ways they were not meant to be, and they can't help themselves but overproduce nutrients of all sorts, with all sorts of unpredictable results. We are like ports where ships continue to unload containers at excessive rates. Some of those containers will end up polluting the area, some will just accumulate into horrible mountains, the motorways will be clogged by a continuous stream of lorries, etc etc etc. Some of those boxes will contain life-saving medicines and some will contain pointless junk, but that's not the actual problem - if you reduce the rate of shipping, then all containers will happily go where they have to go and be dealt with as they "deserve". We were probably not built to have three meals every day. |
