The study shows that women who take more fiber in their teenage life are less likely to get cancer by almost 30 percent. The study shows that an average of 26 grams of fiber should be taken daily. The average American takes around 12 grams of fiber a day, less than half the recommended amount.
"Most of the studies that evaluated the association between dietary fiber intake in midlife or later, have not noted any significant relationship," said Maryam Farvid from "Therefore, it seems high-fiber diet in early life would be important in regards to breast cancer prevention."
The research was done on over 90,000 women between the ages of 27 and 44 who completed a dietary questionnaire. Out of this number 44263 women also completed a questionnaire of their diet while in high school. From the women who completed the high school diet questionnaire, 1,118 of them had breast cancer or exhibited signs of contracting it.
The study divided the women into classes depending on the amount of fiber each took while in their teen years. The study concluded that women who have a higher percentage of fiber in their diet also recorded a significant less probability of contracting breast cancer. The nutrient is readily available in fruits, vegetables, and whole foods.
