A long time ago that scientists linked the bad eating habits with an increase in the odds of developing certain types of cancer. Now, a study carried out by researchers from the Department of public health at the University of California, and published in the journal Cancer Epidemiology Biomarkers & Prevention, noted the relationship between poor diet in adolescence and early adulthood and risk of breast cancer in women before menopause.
An unhealthy diet in early adulthood is related to a 41% increase in the odds of developing breast cancer before menopause
For results, scientists departed from data of more than 45,000 women, all of them from the Nurses Health Study. Some of these women completed in 1991 – when all had between 27 and 44 years – a form of frequency of food in your diet. They were filling out this questionnaire again every four years, while in 1998 asked that they were recalling what had been their diet during his years in high school, in his adolescence.
With data in hand, the Californian researchers divided women into five groups according to inflammatory diet capacity (higher the smaller was the intake of fruits and vegetables and more processed meats and sugars and refined carbohydrates). With the five groups established, scientists found how women who were in the Group of the most unhealthy diet in adolescence had 35% more likely to have a breast cancer before menopause, that were part of the group that had taken a more healthy diet at this age. The percentage rose to 41% when comparing the diets in early adulthood.
Breast cancer, a public health problem
According to the Spanish Association against Cancer, breast cancer is the type most common malignancy in women, with an incidence of more than 25,000 new cases per year, representing almost 30% of all female tumours. Also, despite scientific advances, that they are increasing the survival rate at 1.4% per year, is causing more deaths (over 6,000 in 2012). In fact, experts estimate that one in eight women will suffer this disease throughout his life.
Spanish figures are common to all Western countries, including the United States. For this reason, and despite the fact that data from the study have limitations and cannot prove the relationship between poor diet and the development of breast cancer early, researchers emphasize the importance of a healthy diet to prevent as far as possible the development of these tumors.
