Experimental investigations in the past 10-15 years have provided convincing evidence of the cancer preventive potential of berries. Berries and their components have been shown to reduce the malignant properties of cancer cells in culture by influencing genes associated with cancer development. In addition, diets containing freeze-dried berries have been shown to prevent cancer in animals, and recent data indicate that they also exhibit cancer preventive effects in humans.
