Sugar – Cancer Link. Does sugar feed cancer? Endocrinologist and prominent nutrition expert Dr. Robert Lustig, MD, discusses increasing evidence that excess sugar consumption is linked to growth in cancer in Western society. “Cancer: diseases of civilization” by Vilhjalmur Stefansson is the first book that linked Western diet and cancer. Sugar can lead to cancer growth. Sugar and Cancer link. Does sugar feed cancer? Excess sugar consumption is likely associated with increased cancer risk. Arctic inuits had low sugar and low processed food diet. Inuits practically did not have cancer. There is a link between sugar and cancer. It is mediated by increase in insulin growth factor. Is link between sugar and cancer myth? Sugar and Cancer link is becoming more established. Or does sugar feed cancer cells? Mutations in insulin growth factor (IGF) allow cancer cells to take in and metabolize sugar more efficiently. Vilhjalmur Stefansson studied inuits and wrote book “Cancer: diseases of civilization”. Sugar can lead to cancer growth. But is there causation between sugar consumption and increase in cancer? Video interview with leading expert in pediatric endocrinology and nutrition. Dr. Anton Titov, MD. Medical second opinion about insulin excess. Insulin resistance diagnosis is correct and complete. Dr. Anton Titov, MD. Medical second opinion confirms that insulin resistance metabolic syndrome treatment is required. Sugar and Cancer link is now accepted by many scientists and clinicians. Dr. Anton Titov, MD. Medical second opinion helps to choose the best treatment for metabolic syndrome. How to evaluate insulin resistance? Get medical second opinion on metabolic syndrome and insulin resistance and be confident that your treatment is the best. Do not ignore Sugar and Cancer link impact on your health. Sugar cancer link. Dr. Robert Lustig, MD. There is much research that points out to role of insulin and insulin-like growth factor in cancer. Absolutely. Cancer rates have increased in an industrialized society in the twentieth century. Indeed. Much is known about cancer mutations that mimic insulin effects. Mutations in cancer cells also make cancer more sensitive to endogenous insulin. It is insulin produced by the body). Absolutely. You are saying that sugar drives insulin levels to increase. There is approximately a three-times increase in insulin levels over the last several decades. Cancer rates also increased. That is true. Is there a role for sugar in cancer? Does eating sugar increase risk of cancer? Medical medical second opinion, MD (Neuroendocrinologist, UCSF. Author, “Fat Chance: The Bitter Truth About Sugar”): So. In order to say that sugar causes cancer, you have to actually demonstrate causation. Dr. Robert Lustig, MD. We have not done that yet. Dr. Robert Lustig, MD. We are not quite at that level of inquiry yet. There’s a lot of concern about this. Dr. Robert Lustig, MD. We are concerned that sugar causes cancer. Dr. Robert Lustig, MD. We have a lot of indirect data that would implicate sugar. Sugar is at least a risk factor in cancer. There is no confirmation yet of sugar directly causing cancer. Dr. Robert Lustig, MD. We have a plausibility argument. It related to these hydrogen peroxide molecules. Dr. Anton Titov, MD.’s note: Dr. Robert Lustig, MD, discussed this earlier in the interview. Dr. Robert Lustig, MD. We have a mechanistic argument. It explains how sugar is metabolized in cancer cells. Dr. Robert Lustig, MD. We know what happens within cancer cells to increase amount of energy produced in cancer cells. Cancer growth needs energy. This energy-producing process is called Warburg effect. Fructose is a sweet molecule in sugar. Fructose drives Warburg effect. Dr. Robert Lustig, MD. We have correlation studies. Studies investigated people who consume higher doses of sugar in their diet. Research showed an increased risk of several different cancers. All those arguments that link sugar and cancer are very important. But they don’t actually solve the question of causation. Today I cannot categorically state that sugar causes cancer. Am I worried about it? Absolutely! Dr. Robert Lustig, MD. Certain groups of people, several tribes, do not eat Western diet. Or they did not previously eat typical Western diet products. Western food products contain saturated fat and sugar-rich foods. Example of such tribe is Arctic Inuits. Arctic Inuits had very low rate of heart disease and cancer. But eventually Inuits started to eat Western diet. Then heart disease and cancer significantly increased. Western diet probably contains not just saturated fats. But it also has high amounts of sugar in many foods. Dr. Robert Lustig, MD. That’s interesting. The chair I am sitting in right now belonged to an Arctic explorer named Vilhjalmur Stefansson. He didn’t go to the North Pole first, but he went to the North Pole most. He made many trips to the North Pole. He was the first person to notice that the Inuits had virtually no cancer whatsoever. He wrote a book back in 1960 called “Cancer: the disease of civilization”. This is his chair. Medical medical second opinion. This is ironic. It is my legacy to pursue the problem of cancer and western lifestyle. Sugar Cancer link. Does sugar excess cause cancers? Video interview with Dr. Robert Lustig. Cancer rises with excess sugar in food. Is sugar a new smoking?
