Broccoli Boosts Immune Health

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.

In particular, sulfurophane was found to restore immune function in the older animals. The scientists discovered that dendritic cells, which introduce infectious agents and foreign substances to the immune system, were particularly effective in restoring immune function in aged animals when treated with sulforaphane. Researchers suggested including these vegetables as part of a healthy diet. And looking to the future, free radicals may only be part of the answer.
