Plant science and human nutrition: challenges in assessing health-promoting properties of phytochemicals.

摘要

The rise in noncommunicable chronic diseases associated with changing diet and lifestyles throughout the world is a major challenge for society. It is possible that certain dietary components within plants have roles both in reducing the incidence and progression of these diseases. In this article, the types of evidence used to support the health promoting activities of certain phytochemicals and plant-based foods are critically reviewed and the major contributions but also the limitations of epidemiological and observational studies and research with the use of cell and animal models are summarized. The need for human intervention studies to provide high-quality evidence for health benefits of dietary components derived from plants is also discussed
