For more than 30 years, evidence has shown that people who regularly consume fruits and vegetables have a lower incidence of age-related diseases such as cancer, cardiovascular events, diabetes, osteoporosis, cataracts, and arthritis. Research shows that the wealth of phytochemicals that naturally occurs in plant foods is, in part, responsible for this protection. This body of evidence has greatly expanded in the past few years, identifying new ways that phytochemicals are chemoprotective. Taking supplements of individual phytochemicals has so far been shown as ineffective for protecting ourselves against diseases but eating whole foods that contain these compounds is indeed protective. This course discusses the most current evidence about how phytochemicals in fruits and vegetables consumed as part of our regular diet can protect us from a variety of age-related diseases.


The goal of this course is to provide healthcare professionals with current knowledge about phytochemicals and their role in the maintenance of good health. After studying the information presented here, you will be able to:
  • Discuss at least 5 types of phytochemicals and their evolving role in nutrition.
  • Identify at least 6 foods that are rich in phytochemicals and antioxidants, and explain the mechanisms of action for the various groups of phytochemicals.
  • Educate patients on how to incorporate antioxidants and phytochemicals into a healthful diet.
