Skin Cancer

Dr. Rosedale,

Would a dietary approach, such as yours, provide benefits for skin cancer? A family member has had several operations for skin cancer and while I cannot find anything definitive searching the various medical websites, there seems to be a common theme regarding Omega 3 and Selenium (via diet) providing benefit. In addition, I did see some research regarding a possible connection between Arachadonic Acid and cancers. There's also Dr. T. Colin Campbell's research on the protein casein and cancer.

However, outside of Robb Wolf's website where there's a short discussion on glucose/sugar and cancer, I haven't been able to find any other information on this topic except for Dr. Joel Fuhrman who notes a vegan diet should, after transitioning to his eating plan, should significantly reduce the risk of a cell metastasizing.

    First of all, I am not qualified to give medical advice but you might however find some more things to Google about to become more informed.

    The Rosedale diet lowers the insulin level which is very good since insulin can be regarded as a marker of the hormone IGF-1. Insulin Growth Factor 1 is what makes cells multiply in the body. Interestingly, cancer cells has more receptors for IGF-1 than normal cells so with a high IGF-1/insulin level, the cancer cells will multiply much faster. With the Rosedale diet, you can expect a slower growth of cancer cells but it's not a cure.

    The Rosedale diet will stimulate repair of cells instead of making new cells and that is good for longevity.

    What 's wrong with cancer cells is that they are immortal and will not die eventually as normal cells will do. Also, most cancer will cells thrive on glucose and the Rosedale diet will not feed them well.

    There is some research showing that cancer cells can be converted to normal cells and thus die off as time passes when there is enough vitamin D in the blood. Vitamin D is produced from cholesterol in the skin from UVB radiation so a low fat dietary will not be helpful in avoiding cancer.

    I would recommend your family member to keep in good contact with his/hers doctor and start on the Rosedale diet and also take enough of vitamin D. The doctor might be helpful in monitoring and prescribing the amounts of vitamin D to get blood levels optimal. For healthy persons that has no cancer it is in the range of 2000 - 5000 IU depending of body weight but to be useful for killing off cancer, I have no clue. Safe upper limit is regarded to be below 15000 IU.

    There is no real evidence saying that anything lower than 15000 IU would be harmful in any way. I myself have no cancer and takes 4000 IU every day when I can't get enough from the sun. Also strong antioxidants such as Alpha Lipoic Acid together with vitamin C might be beneficial in prevention.

    Sorry for my English but that's because it's not my mother tongue. Also I am outside US jurisdiction so your authorities can't reach me . Advice regarding cancer is not a good thing to give in public if you are a US citizen but I believe that even FDA would regard my advice as helpful.

    Thanks for the information! Will follow up on you suggestions. I do know there are a number of talks on TED, for example, that discuss plant foods as an anti-cancer source( and research that I came across from the University of St. Louis (here in the US) that identifies:

    1. The omentum (an organ in the abdomen) as a major source of toxins/bad hormones associated with cancer. I believe low IGF-1 is also part of their findings.
    2. Sugar as a food source for cancer.

    Thanks again!

    Thanks Gunar, great answer. Also keeping mTOR low, Dr. Rosedale has done a lot of research on mTOR. So keeping protein lower than what he recommends for people that are dealing with cancer.
