Vegetables serve as the base of the food guide pyramid – but why? Research carried out by environmental scientist Dr. Evelyn Lamy and her team at the Institute of Environmental Medicine and Hospital Hygiene (IUK) at the Freiburg University Hospital shows that cruciferous plants (Brassicaceae) are not only low in calories but also contain healthy substances.
In an ongoing project, Lamy and her colleagues are investigating whether healthy cells are also affected by isothiocyanates. In addition, they are also planning to suppress telomerase activity in order to find out details about the role of this enzyme on the induction of apoptosis through isothiocyanates. In future, the researchers might be able to discover the signalling pathways affected by healthy plant substances. But, in the meantime, it may be wise to follow the advice to eat as much rocket, kohlrabi and mustard as possible.
