Feedback from Our Readers
In the July/August 2002 issue of Geriatrics & Aging (Volume 5, Number 6), the article "Dietary Measures to Prevent Prostate Cancer" (pages 18-20) suggested that dairy foods are strongly linked to prostate cancer, and that the higher the intake of dairy foods, the higher the risk of cancer. Mr. Thomas Anderson, PhD from Summerland, B.C., wrote G&A to point out that only defatted dairy products are known to have this effect (e.g., skim milk and fat-free yogurt), whereas unaltered dairy foods do not, and in fact appear to actually protect against prostate, breast and several other types of cancer.
