Arsenic intake in the world is linked with drinking water and food; the main sources of inorganic As (i-As) exposure in food are rice and rice-based products. The consumption of rice in Ecuador is 53.2 kg year⁻¹ and it is the most commonly used cereal for the preparation of many popular dishes especially for subjects with celiac disease. Objectives of this research were: (i) to determine the content of i-As in foods widely consumed by Ecuadorians with celiac disease, (ii) to calculate the i-As dietary intake, and (iii) to model and predict the health risks of the population under study as a result of their exposure to i-As from rice-based food. The estimated daily intakes of Ecuadorian children (below 3 years of age) and adults were established at 0.52 and 0.55 μg kg⁻¹ body weight d⁻¹, respectively. These values were above the lower BMDL₀₁ value established for i-As established by the EFSA; consequently, it can be concluded that health risk cannot be excluded for the Ecuadorian population with celiac disease.
