It should be noted that there is considerable variability in the prolamine content of various foods made from cereal grains, and this variability is one of the many reasons why food reactions are not consistent. Rice is used as the staple grain in Alpha Nutrition and gluten-containing foods are excluded. Janatuinen et al presented evidence that 52 adult celiacs tolerated oats for one year with no evidence of harm. The study period is too short to be definitive since relapses after longer periods have been observed repeatedly in celiac patients who resumed eating grains. Their study at least again raises the question of what foods can be considered safe in the long term.
Celiac dogma treats the four cereal grains as equally risky.
The older assumptions need to be reviewed by further studies. The general thesis is that immune responses to proteins found in cereal grains are a common cause of disease. Latent disease may manifest as irritable bowel syndrome with iron deficiency anemia, but little or no diarrhea. Celiac disease is associated with a variety of autoimmune disorders, carcinomas of the gastrointestinal tract and lymphomas. These associations suggest a diathesis to immune hypersensitivity diseases and a possible role for food antigens in causing systemic autoimmune disease.
