As for nutrition, it's an interesting thing, really, if you think about how wrong we're probably all doing things.
I mean, first off, let's look at fire.
It's dangerous, all animals run from it, it can kill us as well, it destroys important vitamins and minerals within foods, causes many if not all foods to be at least a little carcinogenic, and tricks our bodies into making food that normally would not be edible, edible, but does that mean our bodies were meant to eat it? So, were we really meant to use fire, heat, microwaves (Oh, don't get me started on those) to heat up food? In my opinion, no.
Now, let's work on meat. If fire isn't supposed to be something we use since it's not a naturally safe thing, then tell me....how palatable are things in the raw to humans such as beef, chicken, or pork? Ever tasted raw beef, chicken or pork? No, and trust me, not a good idea. Not only will it be disgusting, but it'll harbor so much potentially deadly bacteria you could possibly get really sick or, worse, even die (Especially from pork--it's called triginosis). Or, if we were in the wild and had to rely on what nature gave us, would we really be able to tear apart a cow with our bare hands? It's not like we have razor sharp teeth or claws. Or catch a chicken or a pig? We're not exactly the fastest things on the planet. Think about it. About all we seem to be meant to be able to kill and stick in our mouth, honestly, are bugs, and you know THOSE probably taste horrible although, technically speaking from a survivalist standpoint, that's a good way to get protein if you're stranded somewhere.
So, now let's talk about fish. We don't breathe under water. With our own hands, are we able to catch fish or other things in the ocean without using anything? No. Sure, raw fish can taste much better than raw meat so some of it can be edible, but since we aren't water breathers, how would we get fish naturally? Even in freshwater ponds it'd be impossible. The ONLY, and I mean ONLY fish we were probably even meant to catch since it's so easy is when salmon mate and end up in shallow waters during mating season, but even then we'd have to find a way to get through their tough skin with our teeth or fingernails AND usually where the salmon end up are the same places where there's bears, which can eat US.
Now let's talk about grains. Honestly. Ever TASTED raw wheat, uncooked corn, or raw rice? Not only are they disgusting, bland, or could seriously ruin our teeth, I think they were meant for birds, not us.
Next, let's move to vegetables. Literally no calories. Vitamins, yeah, some, but no calories for energy, just vitamins. And most, without something done to them, taste bland bland bland "and" taste horrible raw. They also have no scent. So how would we originally be drawn to them? We wouldn't. We'd just think they were another plant sticking out of the ground. And unlike rabbits, we can't "smell" carrots growing under the ground. Or potatoes or anything else underground related. If we were meant to really ingest any plants, in my opinion, it'd be ones that had an alluring scent, like a lot of herbs, because at least that scent would bring us TO them and when we ate them they'd have a distinct taste. But even then, not a taste that would make us want it really badly.
So, what do we have left? Fruit and nuts. Fruits....filled with vitamins, taste good, we're led to them by scent when they're ripe as well as their colors, and they have calories. So, yes, meant to be eaten by humans. Most definitely.
Nuts. Aren't led to them by scent, and many we have to find a way to crack, but taste good naturally, and aren't overly colorful, but supply protein and minerals.
IMO, humans were, seriously probably only meant to eat fruit, nuts, and perhaps bugs (But bugs are SO pushing it). Honestly. That's it. Nothing else makes sense.
