Colorectal cancer prevention and diet has several similarities.
The colon and rectum are responsible for the nutrient absorption, water management, and the elimination of waste from our body.
A scientist is not needed to tell you that a garbage in equals to a garbage out. Let's see what these experts have to say.
It was found that intake of red and processed meats are a major contributor of colorectal cancer. However, group of doctors in France are unconvinced by this "existing evidence." They've decided to make a comprehensive study for these themselves.
They followed men and women, 478,040 to be exact, for nearly five years before they finally concluded that red and processed meat was a positive cause for colon cancer. They have also found out that eating fish will considerably reduce a person's risk. [Journal of the National Cancer Institute, Vol. 15;97:906-16]
There were many researches involving omega 3 oil, that explains intake of fish can reduce the risk for colorectal cancer.
Doctors associated with the New York University Women's Health Study watched 14,727 women for 7 years. They found out that "a progressive decline in risk of colorectal cancer with increasing the intake of fish and shellfish."
Aside from that, they found that women who are inversely proportionate to the amount of calcium they consume also take a similar decline in its risk. This would mean that, a woman who takes most calcium will get the lowest risk.
But, they were not that confident about the red meat connection to the colorectal cancer as how our friends in France were. Actually, the doctors in NYU said that, the issue of associated of red meat to colorectal cancer "remains unclear." [Nutrition & Cancer, Vol. 28:276-81]
Another study came out in Harvard that suggests that it's not about the red meat and fats, but our "western" lifestyle which causes the problem.
They've mention that obesity, physical inactivity, a diet low in vegetables and fruits, while high in red meat and processed foods all contributes to one denominator of this lifestyle, which is high levels of insulin in the blood!
They have hypothesized that the elevated blood insulin "promotes colon carcinogenesis" this is because, insulin is a "growth factor" that causes cellular division of the epithelial cells in our colon. [Cancer Causes & Control, Vol. 6, No. 2:164-79]
Curious what do we have to do to the colorectal cancer prevention and diet? It's pretty easy.
You just need to stick with whole foods. This includes lots of vegetables, fresh fruit, whole grains and other fiber rich foods. Always use unprocessed oils, like extra virgin olive oil, lean meats that are mostly, fish and chicken, then again, an occasional T-bone won't hurt. Be sure you always get low fat dairy foods, and plenty of pure water.
The studies suggests that it is very important to cut way back on alcohol, start practicing stress management and be sure to exercise on a regular basis.
As you follow these guidelines, it will not only reduce your risk in colorectal cancer, but it includes other cancers as well, adding heart disease and diabetes, too. You will be able to improve your vim, vigor and vitality as well.
