Part I reviews this body of evidence, its strengths and its weaknesses. Chapter 2 discusses the ways in which phenolic compounds may help to prevent cardiovascular disease. Chapter 3 provides an overview of the links between a range of phytochemicals and the risk of cancer. Against this background Chapter 4 looks in more detail at the possible protective role of glucosinolates against cancer, a particularly active and promising area of recent research. The following two chapters concentrate on phytoestrogens. Chapter 5 surveys the current scientific evidence for their wide range of potential functional benefits (a topic also reviewed in Chapter 10), whilst Chapter 6 focuses on the particular topic of bone health. Part I concludes with chapters on carotenoids and flavonoids, and with a broader review of the role of phytochemicals in gastrointestinal health, complementing the earlier reviews of cardiovascular disease and cancer. Against this background, Part II looks at key issues in developing phytochemical functional products. Chapter 10 discusses problems in assessing prevailing and optimal levels of intake, using phytoestrogens as a case study, complementing the discussion of bioavailability in Chapter 7. Since phytochemicals can have harmful as well as beneficial health effects, Chapter 11 reviews ways of testing the safety of phytochemical products, whilst Chapter 12 looks at the critical role of clinical trials in validating functional claims. The final group of chapters looks at production issues, beginning with Chapter 13 which discusses the genetic enhancement of phytochemicals. Chapter 14 looks at the next step in the chain, covering such issues as extraction of phenolic compounds from plant material, and is complemented by Chapter 16 which looks more generally at how to make the most of phenolic compounds at various stages in production. Chapter 15 discusses in more detail the impact of food processing operations on phytochemical functionality. The book concludes by looking at the example of a particular phytochemical product: rice bran. Ï£ÍûºÍʳƷÏà¹ØµÄ³æ×Ó¶à¶à¹ÄÀøÖ§³Ö£¡ [ Last edited by benjazz on 2006-5-10 at 17:31 ] |
