One cancer which is prominent in both men and women is cancer of the colon. Colon cancer is the third most frequent type of cancer in the United States. One interesting fact regarding colon cancer is the relationship between lifestyle and diet, both of which play a major role in the prevention of this cancer.

In an article written by W.C. Willett, "Diet, Nutrition, and Avoidable Cancer," it was noted that an estimated seventy percent of all colon cancer in the United States could have been avoided by dietary changes.

Currently, studies are being conducted on the relationship between soy intake and lab animals. Studies show that the intake of soy protein and different soy flours significantly reduces the chemically induced colon cancers in these animals. It is believed the cancerous tumors in the colon are reduced in growth and formation due to the phytochemical found in soy known as glucosylceramide.

In fact, there are a variety of compounds found in soy foods that may reduce cancer risks. Some studies show that the isoflavones, the estrogen-like compounds, found in soy foods may hold the key. This link may prove that there is a relationship between hormone levels and colon cancer. Another such finding provides evidence that fiber in the diet may reduce a person's risk of developing colon cancer.

Soy products are known for their high amounts of fiber. In fact, soybeans pack more fiber than any other legume and many other plants. Fiber keeps the digestive system working well, cleaning out and regulating the intestinal track. Studies have shown that people who eat a high fiber diet are more likely to avoid colon cancer as well as other cancers and even heart disease.

Although many studies are still in the works, preliminary lab studies are positive regarding the link between colon cancer and soy intake. Currently, research is being conducted on the isoflavones found in soy as it relates to colon cancer, prostate cancer, and breast cancer, all of which are associated with hormone related conditions.

But when comparing Eastern and Western eating habits, soy seems to be the link that has proven to be the diet choice for health benefits. The Journal of Nutrition and the United States Food and Drug Administration both suggest that Americans do need to eat more soy products for the long-term health benefits, as well as their non-fattening and cholesterol free soy proteins.

In addition, The American Heart Association recognizes the many benefits of eating soy to maintain low cholesterol levels among men and women in the States.
