Juice Study


Why are we doing this Study?

People do not eat enough vegetables for health, and it is very difficult to measure how much people are eating. Carotenoids are the brightly-colored pigments in many vegetables and fruits, such as carrots and tomatoes. We can measure carotenoids in the skin of the hand, and are doing this study to see how much juice people have to drink before we can measure a difference in their skin.
