Getting more fiber from fiber supplements (powders and pills), cereals, fruits, veggies (including beans), nuts, and whole grains may not only reduce your risk of breast cancer, but also stop breast cancer progression.

Scientists believe fiber may lower breast cancer risk in several important ways. Some studies have found that fiber reduces the amount of cancer-causing hormones, including reducing estrogen levels in premenopausal women, menopausal women, and breast cancer survivors [1-3]. A recent medical study found that high fiber intakes were associated with a 42% lower risk of postmenopausal breast cancer when comparing women with the highest amount of fiber consumption to women with the lowest amount [4]. Getting enough is very important, so aim for 30 or more grams of soluble fiber every day. You have to plan ahead to eat this amount. I blend a fiber powder into my daily protein shake. Raspberries, pears and apples are three of the best fiber-rich fruits. Oatmeal, corn, beans, nuts, and popcorn are tasty ways to get more. Chewable fiber pills are easy. Drink plenty of fluids when eating fiber. Because a high-fiber diet also helps you lose weight, it is wise to start adding fiber to your anti-breast cancer regimen now.
