Yeah Quinoa is 'better' but quinoa will still contain many proteins that are fine in your intestine, but if they pass through the intestinal wall undigested or partially digested they may be problematic.
The paleo point of view would be that quinoa also contains compounds called saponins that may contribute to intestinal permeability[1].(hence aiding the passage of undigested molecules and the immune response and inflammation that said molecules cause/contribute to).
Gluten free pastas are usually a mix containing corn and that is another problem grain.(read the ingredients, if it says rice and nothing else then that's another story(below), but rice noodle may be cheaper.)
Taco shell, that's corn.
Instead of grains, paleo would recommend carbohydrates from tubers and other vegetables[2]. Some would recommend a restriction (but not elimination) of carb intake, replacing many of the carbs with fats. I have no problem with that as there appear to be many health benefits[3] ,
If i was starting again and did not have to go through years of trial and error because i didn't have access to the world at my fingertips i would use one of two methods depending mainly on my personality type/state of mind (and how long i thought i had to piss around, death's door and all
ale
....
This is what i would do and is
not a recommendation for you to do it.
Do your own research and make up your own mind. (the red pill or the blue pill?)
Option one
Start with a sensible healthy diet (so long as it is not the one recommended by your doctor and your government (7 serves and all))
Coming from a paleo diet i gradually settled on "The Perfect Health Diet"[4] and wished i'd found it sooner.
Unlike paleo (and this guy has really shaken up the paleo world), Paul Jamminet argues that rice is good, because it is toxin free, and the whole deal is whether the food is toxic, not whether its old.
Probiotics are an important part of his diet and he did a series of blogs on IBD [5] that make good reading (there are four parts, and i recommend them all)
This makes the whole thing easier and cheaper than paleo.......
From here more measures and restrictions can be made as some/many may feel much better and others only small improvements.
The idea being that I now fell empowered enough and well enough to take the next step.
-avoiding nuts/eggs/nightshades/dairy/allergies/intolerances/yoga/exercise/leaky gut/past life trauma/carbohydrates/addiction/whatever
The other option, if i felt hardcore and determined, would be the Paleo AI (Auto immune) Protocol[6], (which is as daunting as it sounds).
There is a lot of information on that link but basically a very strict paleo diet (no nuts,eggs,nightshades,alcohol/whatever) for a minimum of 30 days with a gradual and staggered reintroduction of foods There's more to it but that's the gist.
