A response to Dr. John Kelly’s book, “Stop Feeding Your Cancer.”
You can’t build a brick house without bricks. But can cancer cells build starved of their protein bricks?
This is the question that Dr. John Kelly asked after reading Prof. T. Colin Campbell’s “The China Study.[i]” This study concluded that the favourite food of cancer cells happens to be animal protein. Stop supplying the cancer with animal proteins and the cancer will have no building blocks to continue growing.
Dr. Kelly is a general practitioner practising in Sutton, a suburb of Dublin,Ireland. Dr. Kelly’s book, “Stop Feeding your Cancer” recounts the progress of his patients who had and have cancer. His patients also received the standard medical treatments for their cancer including, when indicated, chemotherapy, surgery, and radiotherapy. Dr. Kelly found that those patients who followed an almost complete vegan diet (diet containing less than 5% animal protein) had improved outcomes compared to those who did not follow the suggested diet.
Dr. Kelly also found that the vegan diet did not improve the outcome in two cancers-the stomach and the pancreas. He postula
tes that the stomach and the pancreas produce pepsin and trypsin respectively, enzymes that metabolize proteins and in the cancerous cells these can release proteins for these tumours to continue to grow and metastasize.
Dr. Kelly has not received much support or interest from the medical community for his claims. This is not surprising. Breakthroughs are often slow to be accepted. When Dr. William Harvey proved that blood circulated in the body, it took 30-40 years for the medical community to accept it. Dr. Kelly’s approach seems logical to me. If you don’t feed it it will not grow.
In the Appendix of his book, Dr. Kelly references the study by the University of Southern California The study of 6,318 adults over the age of 50, found that protein lovers were 74% more susceptible to early death from any cause than their low protein counterparts. A “high-protein” diet was defined in the research as deriving at least 20% of daily calories from protein. The researchers recommended in middle age person consume around 0.8g of protein per kilogram of body weight, per day. A “low-protein” diet includes less than 10% of your daily caloric intake from protein.
What do you think? Could it be that a low-protein diet could help the oncologist arrest cancer and improve the prognosis of their patients? What are the pivotal studies that pertain to this low animal protein intervention?
