CRP and celiac disease: Except for high meat consumption (mostly red meat), which increases CRP, other studies have highlighted that elevated CRP and low to moderate grade inflammation can generally be caused by ultra-processed food consumption, and the so-called Western diet (high in processed food, trans fats, sugar, sodium, and refined grains), as well as the frequent intake of saturated and trans fatty acids, milk, butter, gluten (particularly in Celiac disease, which has a higher prevalence nowadays), eggs, and other arachidonic acid-containing foods since it causes inflammation, as well as fish.
