Food Chemistry: Bioative peptides, Phytochemicals, Vitamins & Minerals

Foods contain nutrients that help keep our body alive. The consumption of a nutritious diet promotes long-term health and reduces the risk of chronic disease. Certain constituents found in foods, herbs, and spices known as phytochemicals or bioactives are responsible for changes in health status. Although oxygen is essential for our survival, its relatively high reactivity enables it to form free radicals readily. These free radicals are common and are important components in biological systems where they are essential for the maintenance of life. The overproduction of free radicals can lead to damage of cell components and other biomolecules. Endogenous antioxidant defenses superoxide dismutase, catalase, glutathione peroxidase, and metal binding proteins are inadequate to prevent damage completely, and so diet-derived antioxidants are important in maintaining health. Many dietary compounds have been suggested to be important antioxidants. The evidence for a key role of vitamins E and C is strong, but that for carotenoids and other phytonutrients is weak. There is increasing evidence of the role of food derived peptides in the maintenance of health and prevention of diseases.

Research interests
