Risk assessment of food copper content in He’nan population

Abstract

ObjectiveTo investigate the content of copper in food in He’nan Province， and to evaluate the dietary intake of copper from food and its potential health risks in He’nan population.MethodsBased on the data of copper in foods in He’nan Province in 2014—2021 and the data of Chinese food consumption surveillance in 2012， the dietary intake of copper in He’nan population was evaluated by simple distribution model method.ResultsThe mean and high level （P97.5） daily intake of copper from food by the total survey population were 1.75 mg/d， and 3.51 mg/d， respectively. Of the total survey population， the percentage of people with a dietary intake of copper < estimated average requirement （EAR）， EAR - recommended nutrient intake （RNI）， RNI - tolerable upper intake level （UL）， ≥ UL were 0.21%， 1.16%， 98.10%， and 0.53%， respectively. Cereal （24.51%-40.50%）， vegetables （15.88%-30.98%）， fruits （4.14%-7.72%）， and drinking water （4.70%-6.91%） were the main sources of the dietary intake of copper.ConclusionThe copper intake from food in He’nan population was generally acceptable， and its health risk was small. The proportions of children in 2-3 years old group with an intake of copper less than EAR and exceeding UL were comparatively high， which need to be concerned.
