What are phytonutrients? I keep hearing that these supplements can prevent diseases like cancer. Is this true?

Phytonutrients are naturally occurring components of plants that may have a role in human health. Some phytochemicals, such as vitamin C and E, folate, and beta-carotene, are universally recognized as playing an important role in the maintenance of health.

However, it's the possible link between cancer prevention and many less understood phytonutrients, such as lycopene in tomatoes and isoflavones in soy beans that has generated interest among consumers.

While scientists welcome an increased awareness of the role of plant-based foods in health, they are concerned that publicity over these 'new' phytonutrients is far ahead of the science. They caution that the beneficial compounds must be clearly identified, their mode of action understood, and a safe and effective dose established before dietary recommendations can be safely made.

Fortunately, it is easy for most Americans to increase their intake of phytonutrients by simply eating at least the recommended five servings of fruits and vegetables and six servings of whole grain foods and cereals per day. These low-fat foods are not only packed with phytonutrients, but also provide dietary fiber, protein, and carbohydrates essential to good health.
