07-Mar-2008 - A compound found in broccoli, previously linked to anti-cancer benefits, may also counter the decline in the body's immune system associated with age, says a new study from UCLA.
The compound sulforaphane was found to activate a set of antioxidant genes and enzymes in specific immune cells, which then combat the detrimental effects of free radicals that can damage cells and lead to disease, reports the study in the Journal of Allergy and Clinical Immunology.
"Our defence against oxidative stress damage may determine at what rate we age, how it will manifest and how to interfere in those processes," explained lead researcher Andre Nel from the University of California, Los Angeles (UCLA).
"In particular, our study shows that a chemical present in broccoli is capable of stimulating a wide range of antioxidant defence pathways and may be able to interfere with the age-related decline in immune function."
