Research has found that millions of women are at greater risk of developing breast cancer because they do not get enough fiber in their diet.
According to the newspaper "Daily Mail" British researchers have long warned that the lack of these vital nutrients increases the risk of bowel cancer, but now a recent study by Harvard University found that it is also linked to breast cancer.
The researchers gathered the results of previous studies to create a "meta-analysis." The results showed that women who eat a higher percentage of fibers are 8% less likely to develop breast cancer than women who receive less fiber.
Researchers believe that fibers protect against breast cancer by controlling blood glucose and improving insulin sensitivity.
Cancer cells thrive on sugar, so uncontrolled blood sugar levels help drive their growth. And fibers can also reduce the levels of circulation of the hormone "estrogen", another engine of breast cancer, by increasing the good bacteria in the gut.
Fibers consisting of cellulose and other compounds such as lignin and pectin are found in fruits and vegetables and foods rich in carbohydrates, such as whole wheat bread, pasta and legumes.
The fibers maintain the digestive system in good working order, and help to feel full, as well as protection from heart disease and diabetes.
It is believed that high dietary trends of low-carb and gluten-free diets are the reason for low fiber intake.
"Our study provides evidence that life factors, such as adjustable dietary practices, may affect your risk of breast cancer," said Dr. Maryam Farfaid, the study leader, Harvard University School of Public Health.
She pointed out that eating fruits and vegetables is a very easy way to increase fiber consumption, in addition to whole grains, legumes, seeds, nuts and other good sources.
