Would you expect the pushers of gluten would be avoiding eating it themselves? Govt food pyramid used to have gluten grains at the top.
So: Ashkenazi tradition avoids kitniyot out of concern for accidental consumption of chametz. What is chametz? Chametz are grains that are strictly forbidden during Passover, such as wheat, barley, oats, spelt, and rye. What do wheat, barley, and rye have in common? Those are the three big gluten grains.
What's kitniyot? Corn, rice, soy, and other legumes. Soy we know is bad. And most corn is now GMO corn, and should be avoided. Two more big dietary bad things they coincidentally avoid eating. I ask you: how would someone ever accidentally confuse corn or soy for wheat, barley, or rye?
What's another big dietary health killer? High fructose corn syrup--which they too avoid. What a coincidence they are avoiding that poison too.
Coca-Cola has made a SPECIAL VERSION of their product for Jews during Passover that replaces that deadly poison for sugar. Well, that was sure nice of them. Too bad they don't do it for the rest of us.
Anything else they avoid? Right, pork! Coincidently, the first and most vaccinated meat.
