Change diet to prevent cancer

A really good news for both you and your best friend. One out of three cancer deaths in humans as well as dogs can be prevented by simple, natural diet changes. That's the conclusion of research just presented by Demian Dressler, DVM, at the 2010 Institute of Food Technologists (IFT) Annual Meeting & Food Expo in Chicago, Illinois.

Researchers say that the key is severely limiting snack foods for humans and dogs that contain ingredients rich in omega-6 fatty acids. Omega-3s (found in cold water fish such as salmon and other foods including flax oil and walnuts) and omega-6s (found in meats and some widely used vegetable oils such as corn oil) are essential fatty acids that must be consumed for the body to function properly. Omega-6 fatty acids tend to increase inflammation blood clotting and cell proliferation, while omega-3 fatty acids decrease those functions of the immune system.

The American Institute for Cancer Research reports that the current ratio of omega-6 fatty acids to omega-3 fatty acids eaten by most Americans is about 15-to-1; however, a healthy ratio is closer to 4-to-1.

The glut of omega-6s comes mostly from vegetable oils, such as soy oil, which are used in most of the snack foods, cookies, crackers, sweets, fast foods and -- in the case of dogs' diets -- doggie treats and many commercial dog foods. The result is an eating pattern that promotes inflammation. That, Dr. Dressler stated, creates an environment conducive to cancer in dogs and people.

Another important way to reduce fatal cancers in humans and their canine companions is to keep weight at a healthy level. Dr. Dressler noted studies show obesity in both dogs and humans limits the production of a hormone dubbed adiponectin that inhibits the growth of cancer cells. He recommended reducing calories and especially staying away from sugar -- not only because it contributes to obesity, but also because it is now known to feed cancer cells and spur their growth.
