Cancer Treatments: Is a Ketogenic Diet Better? （转）
Mainstream cancer treatments are expensive, have some pretty debilitating long-term and short-term side effects and for some people and some cancers, not as effective as advertised. What if a ketogenic diet can help improve the outcome of mainstream treatment, and if so, how does it work?
It's been known since the early 1920s that most cancer cells have abnormal metabolisms, and thrive exclusively on blood glucose (sugar) for energy. These cells have broken mitochondria, the cellular organelle from makes energy for the cell, and they are unable to perform normal cellular respiration. In contrast, because they have working mitochondria, normal cells can use either blood sugar or other fuels called ketone bodies for fuel. Ketones are the byproducts of the breakdown of fats in the body.
The important thing to understand is that because of their broken metabolism, cancer cells are vulnerable to any diet which sharply lowers blood sugar.
Dr. Otto Warburg, one of the twentieth century's leading biochemists, discovered this preference for glucose in cancer cells. His hypothesis that cancer cells are only able to use glucose (blood sugar) for fuel is called the Warburg Hypothesis. Recent research and some new information on cancer cell metabolism and metabolic treatments has brought Dr. Warburg's hypothesis back into focus.
Dr. Thomas Seyfried, the author of a book and a 2010 paper called Cancer as a Metabolic Disease writes: "Emerging evidence indicates that impaired cellular energy metabolism is the defining characteristic of nearly all cancers regardless of cellular or tissue origin."
The main idea behind the use of a ketogenic diet to treat cancer is to deprive the cancer cells of the glucose and other fuels they need to survive, and provide support for the mitochondrial respiration processes in healthy tissues.
The huge advantage of this treatment protocol is that unlike mainstream chemo and radiation therapies, the ketogenic diet is non-toxic to the rest of the body, and actually supports the health of normal cells. When glucose or blood sugar is lowered via the diet, normal cells can switch to burning ketone bodies for fuel (ketone bodies are created in a process called ketosis) and survive quite nicely, while the cancer cells are starved of the glucose they need to grow.
Because there is so little information available about using a ketogenic diet for cancer treatments, I have written an eBook which explains in more detail how and why the ketogenic diet works for cancer treatment and gives details on how to implement the diet. It's based on Dr. Seyfried and Dr. Dominic D'Agostino's work at the University of South Florida.
In addition, the use of a ketogenic diet in conjunction with standard treatments is currently being explored in several trials funded by the National Cancer Institute, and more studies are being approved as interest in this "metabolic therapy" grows. |
