Colon cancer is one of the most common types of cancer around the world, with an estimated 1.8 million diagnoses in 2018. It is also the third most deadly, accounting for 881,000 deaths in the same year.
While there are many factors that can contribute to the development of colon cancer, some studies suggest that vegetarianism can be a protective measure against the disease.
What is Colon Cancer?
Colon cancer, also known as colorectal cancer, occurs when abnormal cells develop in the colon or rectum. These cells can then grow and divide at an uncontrollable rate, forming a tumor.
Symptoms of colon cancer can include changes in bowel movements, blood in the stool, abdominal pain, and weight loss.
What Causes Colon Cancer?
There are many factors that can contribute to the development of colon cancer. Some risk factors, such as age and family history, cannot be controlled. However, there are other factors that can be controlled, such as diet and lifestyle.
A diet high in red and processed meats, for example, has been linked to an increased risk of colon cancer. Smoking, heavy alcohol consumption, and physical inactivity can also increase the risk of developing colon cancer.
How Can Vegetarianism Help?
Studies have suggested that following a vegetarian diet can help lower the risk of developing colon cancer. Vegetarianism can help in several ways:.
- High fiber intake: Vegetarian diets are typically high in fiber, which can help promote regular bowel movements and reduce the risk of developing colon cancer.
- Low fat intake: Vegetarian diets are typically low in fat, particularly saturated fat. This can help reduce the risk of colon cancer, as a high-fat diet has been linked to an increased risk.
- Avoidance of red and processed meats: As mentioned earlier, a diet high in red and processed meats has been linked to an increased risk of colon cancer. By avoiding these foods, vegetarians may be able to lower their risk of developing the disease.
- Increased intake of fruits and vegetables: A vegetarian diet typically includes a wide variety of fruits and vegetables, which are high in vitamins and minerals that can help protect against colon cancer.
What Does the Research Say?
Several studies have looked at the relationship between vegetarianism and colon cancer. Here are some findings:.
- A study published in JAMA Internal Medicine in 2015 found that vegetarians had a 22% lower risk of developing colon cancer compared to non-vegetarians.
- Another study published in the International Journal of Cancer in 2018 found that vegetarians had a 19% lower risk of developing colon cancer compared to non-vegetarians.
- A review of 12 studies published in the Journal of Nutritional Biochemistry in 2017 found that vegetarians had a 19% lower risk of developing colon cancer compared to non-vegetarians.
Conclusion
While there is still much research to be done on the relationship between vegetarianism and colon cancer, the current evidence suggests that following a vegetarian diet may be a protective measure against the disease.
Vegetarian diets are generally high in fiber, low in fat, avoid red and processed meats, and include a wide variety of fruits and vegetables. These factors can all contribute to a lower risk of developing colon cancer. If you are concerned about your risk of colon cancer, talk to your doctor about incorporating more vegetarian meals into your diet.
