Functional Foods, Part 1
Updates throughout this important course help practitioners sort through the many "functionality" claims for foods and supplements. As evidence that dietary components have protective functions accumulates, the potential for misinformation and misunderstanding increases. This course concentrates on the proven functional components of whole grains, fruits, vegetables and legumes, including phytochemicals. A lengthy section on soy foods' effect on heart health, cholesterol, female hormones and diabetes is featured.
