title: Metabolic Biosynthesis of Potato (Solanum tuberosum l.) Antioxidants and Implications for Human Health.
abstract: Potato (Solanum tuberosum L.) is common, affordable, readily stored, easily prepared for consumption, and nutritious. For these reasons, potato has become one of the top five crops consumed worldwide. Consequently, it is important to understand its contribution to both our daily and long-term health. Potato is one of the most important sources of antioxidants in the human diet. As such, it supports the antioxidant defense network in our bodies that reduces cellular and tissue toxicities that result from free radical-induced protein, lipid, carbohydrate, and DNA damage. In this way, potato antioxidants may reduce the risk for cancers, cardiovascular diseases, diabetes, and even radiation damage. A better understanding of these components of potato is needed by the food industry, health professionals, and consumers. This review provides referenced summaries of all of the antioxidant groups present in potato tubers and updated schematics including genetic regulation for the major antioxidant biosynthesis pathways. This review complements current knowledge on the role of potato in human health. We hope it will provide impetus toward breeding efforts to develop cultivars with increased antioxidant capacity as 'functional foods' and encourage potato consumers and processors to work toward preservation of antioxidant capacity in cooked potato and potato products.
