Carotenoids in spinach Homegrown spinach not only tastes better than what's available in the supermarket, recent evidence from Klaus Albert and co-workers at the University of Tubingen (Germany) suggests that it actually may be better for you. Spinach contains carotenoids, such as lutein and zeaxanthin, which have strong antioxidant behavior. These carotenoids, however, are relatively unstable in the presence of air and UV light, so by the time spinach reaches the market it may have lost much of its antioxidant power. like many plant ingredients, carotenoids have bom cis and trans isomers, which differ greatly in their biochemical activity. Knowledge of the stereochemistry of active species is critical to understanding how such compounds protect against various diseases. For example,
