Here is an article published in Live Science. This article talks about how consuming more fiber in the teenage years can lower the chances of breast cancer in women in later years. One of the reasons this happens is because most of the fiber containing foods are also source of rich anti oxidants especially when consumed in less processed or raw form. These anti oxidants help our bodies fight cancer and improves immune system.
Another interesting angle proposed in the study suggests that estrogen hormone is regulated by consuming more fiber.
So Here is the full article.
Teenage girls and young women who eat a lot of foods high in fiber, such as fruits and vegetables, may have a lower risk of breast cancer later in life, a new study suggests.
Summary of Research
The researchers found that the women who consumed high amounts of fiber during early adulthood had a 12 to 19 percent lower risk of developing breast cancer over the 20-year study, compared with the women who consumed very little fiber in early adulthood.
And the women who consumed high amounts of fiber during their teenage years had a 24 percent lower risk of developing breast cancer before menopause, compared with those who consumed little fiber as teens.
