Loren Cordain mentions on his book that Paleolithic people did eat some grains, but only when there was a famine; it was not a staple. Gluten builds intolerance over time, and the real problem is that after the Paleolithic times, grains became a staple. This is how cities were built: because constant supply of food (grains) allowed that. It was not a staple, or even a regular food in the Paleolithic times.
Today, it's even worse: people start their day with cereal, they eat pasta for lunch, and pizza for dinner. And a donut for snack. This is wheat, with wheat, and some more wheat. People today are UNDER-NOURISHED because they don't eat enough real food. Not only wheat doesn't offer much in terms of nutrition, but it stops nutrients from other foods to be absorbed too (explained here Why you should probably stop eating wheat ).
Instead, if a less-manipulated version of grains was to be used rarely (e.g. 3-4 fermented-bread slices a week), then there would be no problem for new people, because tolerance wouldn't built on individuals as fast (gluten becomes a problem after a few years usually, manifesting as some random disease, after having too much of it). It's already too late for us, our immune systems can't handle it anymore. Staples are bad, no matter how you look at it. People must rotate their foods as much as possible in order to get as much nutrition as possible. This is why my daily plates always have over 10 species of veggies (raw and not), and both wild fish and pastured meat (with different fruits as desert). And it's not expensive! It's usually $5 per person. Overall, about $15 per day, per person.
Besides, just because Grok did a few grains, doesn't mean that it was healthy. They also ate things that were not particularly good. Heck, dogs and cats would also eat whatever they find, and you would think that their noses would tell them if something is poisonous for them or not. Why wouldn't Grok eat whatever he could find? Unfortunately, these noses don't tell them if a food is bad in the LONG run. That's the key with gluten. It's sneaky!
As I wrote in one of my comments above, the Paleo diet is simply based on evolution and research, not a single Paleolithic diet (especially since there wasn't a single Paleolithic diet). Today, we have numerous research papers on how terrible grains are for our health. Not to mention the thousands of anecdotal reports about its effects.
Regarding oats: make sure they're labeled as gluten-free. I was in Greece a few weeks ago, and passed by several grain fields. Wherever oats grew, wheat or rye were right next to it. They usually grow together, so be sure your oats are labeled as GF. Same goes for lentils (search for barley grains when you open their package).
As for rice, it's the least bad grain. I eat it twice a month with my sushi (along gluten-free soy sauce that I carry from home). But rice is not without its problems either. I can eat without a problem Japanese and Greek rice, but I'm having problems with Chinese and Indian rice. So it depends on the species too (same for a friend of mine who had similar health problems to mine). But overall, it's way down on the scale of badness compared to modern wheat IMHO.
Organic corn is not too bad either (GMO corn is pretty bad for different reasons though).
