With immungenic proteins, are simple carbs loaded with them only? Or, are they in complex carbs as well?
I assume you're stating that a restricted complex carb diet is the best option. Correct?
Hey Smoothy. The immunogenic proteins are found in legumes and grains. Some are more immunogenic, some are less. Obviously everyone knows about gluten, but all grains and legumes have storage proteins called prolamines. Humans don't make sufficient levels of the enzyme that breaks these proteins down so they move through the GI tract undigested and can wreak havoc. Everyone knows what celiac disease is, but few understand how it works. Basically, gluten gets broken down to gliadin and glutenin, gliadin appears to be the worse of the two. In all humans, gliadin attaches to receptors of intestinal cells and causes the release of zonulin which dissolves tight junctions between the cells and let's shit(Literally) enter your bloodstream that shouldn't. In a normal person, this is on the time scale of milliseconds, in celiacs it's much longer. However, if all you eat is processed shit, you are getting mega doses of grains(Mostly wheat) and legumes(Primarily soy with some peanuts sprinkled in).
I don't think moderate dosages of these foods will cause major problems as long as you are getting a lot of veggies in to help repair the gut damage as well. Your gut bacteria ferment soluble fibers from veggies and the product is butyric acid, which heals the intestinal wall. If you are someone with blood glucose control issues or someone trying to get very lean, cut grains and legumes out of your diet and watch what happens. Legumes are less of an issue because they tend to be packaged with soluble fiber, but they don't really taste all that good anyway unless they are in processed foods and why cause the damage? As you get older your immune system becomes less efficient, and the dosage of these foods you eat will more than likely have to be reduced.
I don't really recommend a low carb diet, especially to people who lift. You can go low carb, but there is a bunch of other stuff you have to do and you have to keep your carbs low permanently which I don't want to do. You can carb cycle, but I'm not a big fan as increasing carb intake reduces your ability to make ketones which is your brain fuel on low carb days. You can work around this by taking MCT oil or using coconut oil. I get most of my carbs from white potatoes and other tubers, white rice, and low fructose fruit. Of the grains, rice is the least allergenic which is why it is one of the first you introduce to babies. White is better because a lot of the storage proteins are found in the husk, bran and germ which is stripped away. This also happens to be where all of the nutrient binders are as well.
I'm sure someone will pop in here and say grains and legumes are nutritious foods. They really aren't. Here is a talk from Mat Lalonde going over the nutrient densities of different types of food. Grains and legumes were the worst, and that's not including both's ability to bind nutrients in the gut, he assumes 100% bioavailability which actually gives these foods a higher score than they should have.
