  Purpose

This pilot, three-week study will help scientists understand more about how the foods people eat can modify histone deacetylases, enzymes the body produces naturally. Broccoli sprout extract and garlic oil are thought to modify these enzymes. The purpose of this study is to see if taking broccoli sprout extract alone, garlic oil alone, or broccoli sprout extract and garlic oil together, can decrease the action of histone deacetylase (HDAC) and turn on genes in white blood cells. There will be 80 people in this study.
