Diet... *!

A study published in the journal Pediatrics concludes that eating lots of fiber-rich foods during high school years may significantly reduce a woman's risk of developing breast cancer.

Women who consumed high levels of fiber (28 grams per day, on average) had a 24 percent lower risk of developing breast cancer before menopause, compared with women who ate low levels of fiber.

Fiber can prevent constipation and keep the bowel moving by making stools bulkier and absorbing water. Dietary fiber can protect against colorectal cancer and may lower the risks of diabetes and heart disease and helps with weight management.

"Dietary fibers may reduce circulating estrogen levels." And this may help explain the reduced risk of breast cancer. The authors point to other possible explanations, high-fiber diets may reduce the risk of breast cancer by improving insulin sensitivity, since fiber can slow down the absorption of sugars and help keep blood sugar levels more stable.

Maryam Farvid, a fellow at the Harvard School of Public Health who is lead author of the study, says the influence of fiber on cancer risk may be time-sensitive. Adolescence is "a period when breast cancer risk factors appear to be particularly important," she says.

People's dietary habits don't really change a lot. ... In general, what you eat as a teenager is really formative as to what you eat later in life." Fiber can help you lose weight.

Just a thought.
