CURRENT RESEARCH INTERESTS

"Let food be your medicine" - Hippocrates

Projects focus on nontraditional components in plant foods that can potentially prevent or delay onset of diseases related to aging. At the heart of my current activities are a battery of techniques for measuring antioxidants in plants and foods including cereal grains and grain products. Can we follow these throughout food processing and food consumption? - You bet! That is the whole idea. Collaboration is welcome on food production, processing, nutrition and human health in the general areas of food antioxidants and polyphenols.
