Quercetin
Appears to Decrease the Risk of Colon Cancer

Increased dietary intake of the flavonoid quercetin, found in onions and apples, appears to reduce the risk
of developing colon cancer by 50 percent.
Studies show diets rich in flavonoids may reduce the risk of developing colorectal cancer (colon cancer and rectal
cancer). Flavonoids are found in plant foods. Tea is a source of flavonoids that decrease colorectal cancer and
most other cancer risks.
This research study evaluated the association of colorectal
cancer in a population group in which tea provides the main source of flavonoids. This group still has a high
rate of colon cancer. Dietary data was gathered to calculate flavonoid intake.
Researchers found the highest dietary intake of the flavonoid quercetin decreased the risk of colon cancer by 50
percent. Dietary quercetin did not decrease the risk of rectal cancer.

This group of people has a tendency to consume a large amount of preserved meats, alcohol and processed
carbohydrates (bread). All of which increase the risk of colon cancer and rectal cancer. Their high amount of tea
consumption does not compensate for their cancer promoting diet.
As expected, high intake of vegetables and fruit decrease the risk of cancer including colon cancer. We should be
eating 7 to 13 servings (about 4 to 6 cups) of vegetables and fruit each day. I take Green Drink to supplement my dietary intake of vegetables and fruit.
