Vitamin D Deficiency Linked To Higher Risk Of Colorectal Cancer

February 16, 2010 by  

Vitamin D deficiency linked to higher risk of colorectal cancerA large European study has found that low levels of circulating vitamin D are associated with a higher risk of developing colorectal cancer.

From 1992 to 1998, more than 520,000 participants from 10 western European countries completed detailed dietary questionnaires and gave blood samples. After tracking the subjects for several years, researchers identified 1,248 cases of colorectal cancer.

After matching those cases with the same number of healthy controls, the study’s authors found that participants with high levels of vitamin D experienced a 40 percent decrease in colorectal cancer risk when compared to subjects with the lowest levels.

However, while below average vitamin D levels were associated with an increased risk of developing the disease, extremely high levels of the nutrient were not related to any additional reduction in colon cancer risk.

Separate studies have also linked vitamin D to the regulation of glucose control, blood pressure and inflammation, three important risk factors associated with heart disease.

The best known sources for the nutrient are the flesh of salmon, tuna and mackerel as well as milk. The vitamin can also be taken in the form of nutritional supplements.

    I’m probably a little more able to accept this medical better-health information than all the “stuff” about global warming! Why? Because I know that not even the biggest money-making private industry(medical) is not as corrupt as our governments, local, state, and Federal! I’d have more confidence in our governments if only self-made financially successful business persons ran all government operations than lawyers doing it!

    Soon, Americans will finally understand that most health care professionals (MDs) are not fit to give advice concerning basic nutrition issues. They are NOT trained in basic health. Even today, a typical American-trained MD MAY get ONE course that has anything to do with nutrition. HOW can an MD know ANYTHING about nutrition via ONE course in medical school?
    Educate yourself. Take chare of your own health care. Take the advice of those who get RESULTS.
    Anyone who claims to get results merely because he or she muddled through medical school might as well be a door-greeter at WalMart (or a medical czar for a White House twit).
    People who get results are true health care professionals. Those who crow about reputations they haven’t earned ARE QUACKS!

      What happened? Our Doctors used to be revered because of their humanity, their intelligence and knowledge and application of that knowledge for the benefit of their patients. They respected their patients. Today, for instance, I call one doc I see “Dr. Doorknob” because immediately after an exam he backsteps, puts hand on doorknob and starts opening the door before he finishes a sentence regarding my exam. Another gal advised me of the immediate emergency for some surgery… I saw her office with fancy rugs hung on walls and other arty decoration, elaborately expensive “livingroom” type furnishings, and because of her rushing me I backed off. Got another exam immediately and was told no way, a surgery is absolutely not necessary nor advised. 7 years passing has proven him right.
      From what I know about med schools, and internships, they are pushed beyond necessity. Of course testing endurance is important, we don’t want docs unable to fully attend to lengthy hours of a surgery… but the routine exhausting of students isn’t good. Other situations are caused by the AMA, and the Boards that limit school enrollment according to income perspectives for students… AND race and ethnicity counts that prevent many Americans from becoming doctors. We need to focus attention on those factors and get them fixed because they are wayyyy out of line with what our country used to provide in medicine. Until we have the determination to make the situation better for our OWN citizens to become doctors, we are going to continue getting the mess we now have. Also, regarding foreign students, many of us understood, wrongly, that we let them train here, become doctors here, and we expected them to be humane enough to take their skills and talent back to their own countries and help their own people. That hasn’t happened to any degree. Instead, they stay and take jobs here and fill our hospitals and medical facilities, and by their presence deny those jobs to Americans. This causes a great deal of disrespect for foreign doctors, and a growing anger toward our medical institutions. When the President or politician is telling you about their ideas for healthcare, tell them you have an idea about the whole system regarding American Doctors vs foreign doctors TRAINED with American Money.

    How big of a dose would a male adult need daily?

      Dear Jim,

      Writing in his book, The Vitamin D Cure, James E. Dowd, M.D., says there is no one-size-fits-all amount. Many different things figure into the equation such as amount of sun exposure, type of diet, age, size, skin type and latitude. His book contains a chart that can help you determine how much you would need. There is also a sunshine calculator available online at http://www.thevitamindcure.com/calculator/ that can tell you how much sunshine you need to receive to maintain adequate levels naturally. I take a supplement available at http://www.healthresources.net/itemdy00.asp?t1=Advanced-D3-Plus that gives me 1,000 IUs daily.

      Best wishes,
      Bob

    For over 10 years I endured cracked, peeling and flaking knuckles on the back of my hands, and fingertips. I worked in a bank and it was embarrasing to shake hands with or have my hands displayed. I tried every cream on the market and one doc told me I had psoriasis. Then a new doctor told me my vitamin D level was only 13, as opposed to between 50 – 80, and put me on a 50,000 IU dose of vitamin D3 gelcap, once a month. It took 6 months, but my hands cleared up completely. She took me back off and the condition started to return, so now I am on it regularly, 1x month to maintain. I am sold, but the gel caps work better for me than the pills. By the way, I live in Michigan, where we don’t get the good sun rays.
