    Added fiber to rid body of excess hormones?

    I know in general, fiber is not an issue for the paleo lifestyle. As far as general digestion there is plenty from the fruits and veggies and tubers. In Sara Gottfried's new book The Hormone Cure she recommends women get 35 - 45 grams of fiber per day from diet and medicinal supplement. Her reason is regarding excess estrogen. She says," more dietary fiber increases conjugation - that is, more fiber lowers estrogen levels in the body - and you poop and pee more estrogen out of your system."

    She also says regarding PCOS, "Unless you have sufficient fiber to remove it, most testosterone is secreted into bile and then reabsorbed in the gut and used again. Fiber increases excretion of testosterone in the stool."

    Both of these seem compelling for me since I have both Endo and PCOS.
    Looking at the amount of fiber I get from greens, veggies and fruit I am not getting close to that amount so would need a supplement. Do you agree that this would be beneficial and if so, what kind of supplement would you recommend? gluten free rice bran, oat bran? Thanks for your thoughts on this.

    Ray Peat suggests a carrot salad daily to remove excess estrogen. Just shred a few carrots, add a bit of coconut oil, vinigar and salt.

    She references a number of studies that link a higher fiber diet with lower breast cancer risk. Studies titled "Fat/fiber intakes and sex hormones in healthy premenopausal women in USA"
    " Effect of daily fiber intake on reproductive function: the BioCycle Study"
    "The effects of low-fat/high fiber diet on sex hormone levels and menstrual cycling in premenopausal women: a 12-month randomized trial (the Diet and Hormone Study)

    Yes insoluble fiber supplements are a bad idea. Just eat more veg and fruit.

    Raw coconut is full of fiber. Also unpeeled cacao beans.

    I have been taking acacia powder to help with IBS symptoms. It's a soluble fiber. Supposed to be a prebiotic. It's been helpful. 1 TB is 6g of fiber. No, I will stay away from psyllium husk. The carrot salad info looks interesting.

    Ok, looking at one of the studies she references.... the conclusion concerns me a bit....and confuses. It decreases serum hormones, but increases the probability of not ovulating? How is that helpful??

    Effect of daily fiber intake on reproductive function: the BioCycle Study.
    Gaskins AJ, Mumford SL, Zhang C, Wactawski-Wende J, Hovey KM, Whitcomb BW, Howards PP, Perkins NJ, Yeung E, Schisterman EF; BioCycle Study Group.

    Abstract
    BACKGROUND:
    High-fiber diets have been associated with decreased breast cancer risk, likely mediated by the effect of fiber on lowering circulating estrogen concentrations. The influence of fiber on aspects of reproduction, which include ovulation, has not been well studied in premenopausal women.
    OBJECTIVE:
    The objective was to determine if fiber consumption is associated with hormone concentrations and incident anovulation in healthy, regularly menstruating women.
    DESIGN:
    The BioCycle Study was a prospective cohort study conducted from 2004 to 2006 that followed 250 women aged 18-44 y for 2 cycles. Dietary fiber consumption was assessed < or =4 times/cycle by using 24-h recall. Outcomes included concentrations of estradiol, progesterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), which were measured < or =8 times/cycle, and incident anovulation.
    RESULTS:
    Dietary fiber consumption was inversely associated with hormone concentrations (estradiol, progesterone, LH, and FSH; P < 0.05) and positively associated with the risk of anovulation (P = 0.003) by using random-effects models with adjustment for total calories, age, race, and vitamin E intake. Each 5-g/d increase in total fiber intake was associated with a 1.78-fold increased risk (95% CI: 1.11, 2.84) of an anovulatory cycle. The adjusted odds ratio of 5 g fruit fiber/d was 3.05 (95% CI: 1.07, 8.71).
    CONCLUSIONS:
    These findings suggest that a diet high in fiber is significantly associated with decreased hormone concentrations and a higher probability of anovulation. Further study of the effect of fiber on reproductive health and of the effect of these intakes in reproductive-aged women is warranted.

    I don't read a lot of studies myself. From the blogs I read, it is clear that the results of many studies are misrepresented by the researchers in order to turn out a favorable press release. And then the media just prints their press release without even examining the paper.
