"Natural remedy for cancer discovered!" Now, that got your attention, right? Researchers all over the world are looking for that magic cure. There is an increasing amount of research, however, demonstrating that diet plays a much more important role in the fight and prevention of cancer than previously given credit. Every year, about 1.3 to 1.4 million people are diagnosed with cancer. Most health experts now believe about one-third of all cancers are caused by poor diet.

"To put it another way, unhealthy eating habits can shorten your life," said Barbara Casaceli, RD, LDN, Marlborough Hospital Outpatient Nutrition Department, who works with patients every day addressing weight management and nutrition issues.

"Being overweight or obese increases one's risk for heart disease and diabetes, but what many don't know is that it can also increase the risk for certain cancers. Hand-in-hand with being overweight are often issues of poor nutrition," said Ms. Casaceli.

The prescription for better health is to follow a low-fat, high fruit and vegetable-based diet. Load up on fruits, vegetables and whole grains. They are naturally low in fat, chock-full of fiber, and filled with cancer-fighting antioxidants and phytochemicals.

Phytochemicals are nutrients found in plant-based foods. There are thousands of these health-promoting, naturally occurring substances in plants, including vitamins, minerals, and many other substances that are important for cancer prevention. Only plants, including vegetables, fruit, whole grains, legumes, nuts and seeds, contain these healthful phytochemicals. And research shows that the more plants, and therefore the more phytochemicals you eat, the lower your risk of cancer and other diseases.

"I encourage my patients to cut down on fatty foods, added fats and oils, particularly saturated fats, which have been linked to an increased risk of breast, colon, and prostate cancer. Also to look for healthy substitutes for dairy products, including milk, cheese, and yogurt, which have been implicated in the occurrence of breast and colorectal cancers," Ms. Casaceli explained.

Alisa Himelfarb, MS, RD, LDN, also an outpatient dietitian explained, "Beyond eating plenty of plant foods, focus on a variety for optimal cancer prevention benefits. If you only eat foods that are familiar to you, you'll miss out on the maximum cancer fighting benefit other foods have to offer. Try to branch out by trying something new or different such as eating kiwis, dark cherries, mangos and guavas."

Further stressing variety in her patient's diets, Ms. Himelfarb asks, "Not counting potatoes, peas and corn, what vegetables do you regularly eat? Do you eat fresh spinach and broccoli every week? What about the other green, leafy foods, such as kale, collard greens, mustard greens, dandelion greens and bok choy? Do you include asparagus and squash? Again variety in the type of vegetables is important."

"As we all know making changes are not always easy. We try to encourage our patients that small changes really do work. The bad habits did not occur overnight and neither will correcting them," concluded Ms. Casaceli.
