Colon Cancer

Digestion Suggestions: Eating Your Way to GI Health


Medically Reviewed On: May 07, 2005

It's no surprise that eating right can put you on track for good health. Some argue that a nutritious diet can even lower your risk of certain cancers, though the relationship between eating habits and cancer is not fully clear. For example, while some studies have shown that diet has no significant influence on colorectal cancer risk, other studies have demonstrated that particular foods can have an impact.

No matter which cancer studies are correct, a well-balanced diet can only improve your overall gastrointestinal (GI) health. And if refurbishing your diet decreases your risk of colorectal cancer, so much the better. Lynn Goldstein, a registered dietitian and nutritional educator at the New York-Presbyterian Hospital and Weill Medical College of Cornell University in New York City, explains how to make the most of your munching.

What role does diet play in cancer prevention?
It was never originally thought that diet had a significant impact on cancer, but it actually may play a role in many cancers, particularly in gastrointestinal cancers. In 1997, the American Institute for Cancer Research took about 4,500 different studies that focused on food and nutrition from around the world. They found that up to 75 percent of all GI cancers could actually be prevented through appropriate diet and nutrition.

What is preventative eating?
When I say "preventative eating," I really mean choosing or excluding specific foods that may affect your risk of cancer. There are so many factors in cancer risk that we can't control, like age, genetics or the environment. But we can control what we put into our mouths.

What are the ingredients in a gut-friendly diet?
Whole grains are good because they are full of vital nutrients. One of these is fiber, which helps regulate bowel function, prevent constipation and keep us fuller longer.

Low-fat dairy products are good foods because they have calcium and vitamin D, both of which have been shown in some studies to reduce the risk of colon cancer.

Fermented dairy products, like yogurt, also have probiotics, which are healthy gut bacteria that help fight intestinal diseases by decreasing any bad bacteria that try to take up residence in the gut

Fruits and vegetables have almost all of the vitamins and minerals that our bodies need to function. They strengthen our immune system and give us energy. Fruit contains antioxidants, the chemicals that create their colors, which help fight off disease. Leafy green vegetables such as spinach and lettuce are rich in folate, a B vitamin that has been shown to protect against colorectal cancer. Fruits and vegetables also have fiber, which is a great way to keep our gut healthy by flushing out the toxic material in our stool.
