Food Mutagens [PDF]

The Journal of Nutrition, 2003
Several lines of evidence indicate that diet and dietary behaviors can contribute to human cancer risk. One way that this occurs is through the ingestion of food mutagens. Sporadic cancers result from a gene-environment interactions where the environment includes endogenous and exogenous exposures.

Screening for Ames mutagenicity of food flavor chemicals by (quantitative) structure-activity relationship

Genes and Environment, 2020
Background (Quantitative) Structure-Activity Relationship ((Q)SAR) is a promising approach to predict the potential adverse effects of chemicals based on their structure without performing toxicological studies.

Mutagenicity comparison of nine bioselenocompounds in three Salmonella typhimurium strains

Toxicology Reports, 2018
Selenium (Se) is an essential element in animals but becomes severely toxic when the amount ingested exceeds the adequate intake level. It is known that the toxicological effects of Se are highly dependent on its chemical form.
