Non-celiac gluten sensitivity not yet universally adopted. For people on a gluten-free diet who are unable to perform an oral gluten challenge, an alternative to identify possible celiac disease is an in vitro gliadin challenge of small bowel biopsies; this test is only available at selected specialized tertiary-care centers. After exclusion of celiac disease and wheat allergy, the subsequent step for diagnosis and treatment of NCGS is to start a strict gluten-free diet (GFD) to assess if symptoms improve or resolve completely. This may occur within days to weeks of starting a GFD, but improvement may also be due to a non-specific, placebo
Wheat gluten (food) observed a week of vegetarianism each year. "Miàn jīn" is often deep fried before being cooked in Chinese cuisine, which confers a crispy rind that enhances the texture of the gluten. There are three primary Chinese forms of wheat gluten. Oil-fried gluten (, "yóu miàn jīn") is raw gluten that has been torn into small bits, then deep-fried into small puffy balls of around 3–5 cm in diameter and sold as "imitation abalone". They are golden brown in color, and braised or boiled in a savory soup or stew before eating. They are frequently paired with "xiang gu" (black mushrooms).
