Low carb diet and breast cancer
A new study in mice suggests that eating a low-carbohydrate, high-protein diet may reduce the risk of cancer and slow the growth of tumors already present. (BMI can be calculated by dividing weight in kilograms by height in meters, squared. D. Krystal and his colleagues implanted various strains of mice with human tumor cells or with mouse tumor cells and assigned them to one of two diets. Low-carbohydrate, high-protein diets may reduce both tumor growth rates and cancer risk. Eating a low-carbohydrate, high-protein diet may reduce the risk of cancer and slow the growth of tumors already present, according to a study published in Cancer Research, a journal of the American Association for Cancer Research. Study participants must be at least 30 years old, and have a body mass index (BMI) between 25 and 34. They found that the tumor cells grew consistently slower on the second diet. As well, mice genetically predisposed to breast cancer were put on these two diets and almost half of them on the Western diet developed breast cancer within their first year of life while none on the low-carbohydrate, high-protein diet did. Participants will be expected to exercise regularly, mostly through walking, building up to 10,000 steps per day, measured by a pedometer, five times per week. The study was conducted in mice, but the scientists involved agree that the strong biological findings are definitive enough that an effect in humans can be considered. Paskett, Ph. Dr.

The second, which is somewhat like a South Beach diet but higher in protein, contained 15 percent carbohydrate, 58 percent protein and 26 percent fat. A new study in mice suggests that eating a low-carbohydrate, high-protein diet may reduce the risk of cancer and slow the growth of tumors already present. There is evidence that both dietary fat and high carbohydrate intake are related to increased vulnerability to breast cancer. Interestingly, only one on the Western diet reached a normal life span (approximately 2 years), with 70 percent of them dying from cancer while only 30 percent of those on the low-carbohydrate diet developed cancer and more than half these mice reached or exceeded their normal life span. Paskett, along with colleagues at Ohio State and Wake Forest University School of Medicine, will spend the next 18 months comparing the impact of each regimen on risk factors for breast cancer among premenopausal women at high risk of the disease either because they are overweight or obese. The women will be randomized to one of two diet plans, a low-carbohydrate arm or a low-fat arm. Laboratory tests have shown that animals placed on high-fat diets develop breast tumors more frequently than those on a low-fat diet. a low-carbohydrate diet may clear up some of the confusion. Electra Paskett, associate director for population sciences at The Ohio State University Comprehensive Cancer Center, hopes a new study examining a low-fat vs. Eating a low-carbohydrate, high-protein diet may reduce the risk of cancer and slow the growth of tumors already present, according to a new study. The first diet, a typical Western diet, contained about 55 percent carbohydrate, 23 percent protein and 22 percent fat.
