Abstract

Background: The traditional Iranian dish, Tah-dig, holds significant cultural and culinary importance. Tah-dig forms as a crispy layer of rice, bread, or potatoes at the bottom of the cooking pot, offering a delightful textural contrast. This study aims to determine the per capita consumption of Tah-dig in Iran. Methods: Data on the per capita consumption of various types of Tah-dig were collected from 1,664 participants using a questionnaire administered between 2021 and 2023. Results: The findings indicate that the most frequently consumed Tah-dig type in Iran is rice-based, with a mean consumption of 0.56 serving/day. Bread-based Tah-dig follows with a mean consumption of 0.52 serving/day, which is higher than the means for potato and macaroni-based Tah-dig, respectively. Conclusions: The overall consumption of Tah-dig among Iranians is notably high. Rice-based Tah-dig demonstrates the highest per capita consumption. Given the potential formation of harmful toxins in Tah-dig during cooking, further investigation into its safety is warranted. © The Author(s) 2025.
