Almost everyone will benefit by reducing the amount of fat in the diet. But a low-fat diet may be especially beneficial for women with breast cancer. A new study, published at the San Antonio Breast Cancer Symposium, suggests that a low-fat diet can prolong the lives of some women with breast cancer.
The preliminary findings were based on women with early-stage breast cancer who participated in the Women's Intervention Nutrition Study, where all women underwent surgery and hormone therapy, or various combinations of chemotherapy and radiation (depending on them) The characteristics of the tumor).
A total of 2,437 study participants, of whom 975 were randomly assigned to a group to restructure their diet. Our goal is to get only 15% of the calories earned by women in this group from fat. To help with this task, they receive eight separate sessions for 16 weeks, and then the dietitian checks every three months. The other 1,462 patients served as controls.
At the beginning of the study, an average of 29.6% of the heat gained by women in these two groups came from fat. Six years later, the number of women in the low-fat diet group decreased to 23%, while the control group climbed to 31.4%. (Women who have a low-fat diet also lose about 6 pounds).
The benefits of fat reduction may be apparent after five years. The researchers report that the female mortality rate in the low-fat diet group was 6.6%, which was nearly 10% lower than that in the control group. The longer the interview, the more obvious this gap. After an average of 8.1 years, the mortality rate of women on those low-fat diets was 9.1%, which was 18 percentage points lower than the control group. However, when the researchers focused only on women who lacked estrogen receptors, the mortality rate of women with low-fat diets was 36% lower than that of women in the control group.
Then, the researchers found that in women who lack estrogen and progesterone receptors, the mortality rate of women on low-fat diets was 56% lower than that of women in the control group. "Three-negative" breast cancer is difficult to treat because they do not respond to drugs such as tamoxifen or Herceptin. Therefore, a lifestyle intervention that may improve the survival rate of these cancer patients will be particularly popular.
