Summary
This narrative review synthesises evidence on glucosinolates in Brassica vegetables, examining how supply chain factors (breeding, cultivation, storage, processing) influence their concentration, composition and human bioavailability. The authors discuss epidemiological evidence linking Brassica consumption to reduced colorectal cancer risk, alongside mechanistic studies on isothiocyanates (glucosinolate breakdown products), whilst noting that human alimentary tract relevance remains incompletely established.
Regional applicability
The review's focus on supply chain effects is broadly applicable to United Kingdom horticultural practice and food processing. However, as an international narrative review, it does not address UK-specific growing conditions, regulatory frameworks, or consumer intake patterns; transfer of findings would require contextualisation to British growing seasons and retail practices.
Key measures
Glucosinolate concentration and composition; isothiocyanate bioavailability; enzyme activities; DNA damage markers
Outcomes reported
The review examined how breeding, cultivation, storage and processing affect glucosinolate concentration, composition and bioavailability in Brassica vegetables, and discussed epidemiological associations between Brassica consumption and colorectal cancer risk.
