Canada has a sustainable supply of agricultural bio-resources, which include not only diverse agricultural commodities but also under-utilized bio-waste generated through agricultural production and processing. The World Health Organization has highlighted a changing world disease profile. In North America, significant challenges are being faced from oxidative stress-linked chronic disease epidemics, which are directly or indirectly linked to diet and the environment. Therefore, chemoprevention through diet modification, i.e. increased consumption of fruits and vegetables as well as the use of novel food ingredients derived from fruits and vegetables, will be important in helping to manage the current and emerging health care challenges. Natural plant compounds with antioxidant and cell signaling modulating properties, such as polyphenolics, triterpenes, and carotenoids, are now widely thought by the scientific community to be the principle components in fruits that provide specific health benefits beyond the basic nutritional functions.

加拿大拥有可持续的农业生物资源供应，其中不仅包括各种各样的农业商品，还包括农业生产和加工过程中产生的未充分利用的生物废物。世界卫生组织强调了不断变化的世界疾病概况。在北美，与氧化应激相关的慢性疾病流行病正面临重大挑战，这些疾病与饮食和环境直接或间接相关。因此，通过饮食调整进行化学预防，即增加水果和蔬菜的消费以及使用源自水果和蔬菜的新型食品成分，对于帮助应对当前和新出现的医疗保健挑战将非常重要。具有抗氧化和细胞信号调节特性的天然植物化合物，如多酚类、三萜类和类胡萝卜素，现在被科学界广泛认为是水果中的主要成分，它们提供了超出基本营养功能的特定健康益处。
