Abstract

Highlights: The impacts of OCS and CCS on wheat nutrition and food safety were evaluated. Biomarkers of OCS, including primary and secondary metabolites, were qualitative and quantitative analyzed. The local population who ingested grains from OCS experienced a higher non-cancer and cancer risks. As and Cr exposure were the greatest contributor to Hazard Index (HI). HMs posed relatively higher non-cancer to children aged 0–5 years and higher cancer risks to adults. Abstract: The influence of cropping systems on nutrition and food safety is controversial. This study aimed to evaluate the effects of an organic cropping system (OCS) on wheat nutrition and food safety at the molecular level by using a comprehensive research method. Nutrient deviation in samples from an OCS and a conventional cropping system (CCS) were detected, and 58 biomarkers were selected through multivariate statistical analysis and were further qualitatively and quantitatively analyzed. The health risk of heavy metal(loid)s (HMs) for different populations was assessed based on the estimated average daily dose and recommended ingestion reference dose, which indicated that populations ingesting grains from OCSs had higher non-carcinogenic and carcinogenic risks. Additionally, HMs posed greater non-carcinogenic risks to children under five years old and greater carcinogenic risks to adults. This study highlights the need to consider the potential risk from HMs and nutritive ingredient differences in organic food.
