For girls and young women, a large US study, after a lot of fiber with a lower risk of developing breast cancer can pay to get decades.
About 20 per cent less likely to develop cancer in their youth were.
Dietary fiber in the long-term impact on cancer risk in ways that could affect the development of breasts have reason to believe that, but no one ever followed up over such a long period, the authors note in the journal Pediatrics .
"Midlife in the assessment of the association between dietary fiber intake or most of the studies, there is no significant association noted," Harvard T.H. Farvid said lead author Mary Chan School of Public Health in Boston. "Therefore, high-fiber diet in the early prevention of breast cancer seems to be important."
Includes, Farvid said. With fiber to the association.
Researchers from 27 to 44 years old when, in 1991, completed a dietary questionnaire to more than 90,000 premenopausal women in the Nurses' Health Study II, the data used. Eight years later, when they were in high school, 44,263 of them also completed a questionnaire about their diets.
High school dietary data in women with invasive breast cancer by 2011 there were 1,118 cases.
Most of the study team when they were teenagers and the low intake of dietary fiber, were divided into five groups of women when they were young women 1991, in.
It connects stool bulk and pass food more quickly through the digestive tract, which helps wheat bran, oat foods, such as water, which attracts and slow digestion, and insoluble fiber like bran food Soluble fiber was true for objects.
In early adulthood, women who have at least Dietary fiber is the most fiber, and the amount of youth who were similar to those over 26 grams per day, consume an average of 12 grams per day.
10 to 15 grams of fiber daily average American now eats the most, according to the National Library of Medicine, the daily should be getting 20 to 35 grams.
"Our results increase during puberty day each additional 10 grams of fiber intake by 14 percent lower risk of breast cancer shows that" 25 to 30 grams per day is recommended by 30% will reduce the risk of breast cancer, Farvid said.
And the amount "is not much fiber a day, twenty-six grams of" a significant reduction in breast cancer risk was associated with, who coauthored a Durham, North Carolina, Duke University Medical Center's Dr. Kimberly L. Blackwell, the Commenting on the new findings.
"I'm a breast cancer doctor and it is very important," Blackwell told Reuters Health.There was, he said. "It will change what I tell my patients."
During her teens growth hormone circulating levels of fiber intake effects, and the risk of breast cancer after hormone levels can affect, he said.
Young adults have healthy eating habits later in life tend to carry the women to get as much fiber, he noted.
Ideally this fiber comes from fruits and vegetables, but also grain or fortified foods can come from, Blackwell said.
"We parents of young daughters at home plenty of high-fiber foods provide and their children enough fruits and vegetables in their diet, whole grain pasta, black bread or brown rice, legumes and nuts, food to ensure that advice, "Farvid said.
