Doctor's Note

Who can forget the Bristol stool scale? Even if you've already seen it you may want a refresher: Bristol Stool Scale. And while we're on the topic, here are some others on optimizing bowel function:

Prunes may also help improve the health of our skin—see Beauty Is More Than Skin Deep.

In general we should try to get our nutrients from whole food, not supplements (Some Dietary Supplements May Be More Than a Waste of Money).
                                                                                                        
See the previous video Dried Apples, Dates, Figs or Prunes for Cholesterol? for a comparison of prunes to other dried fruit in terms of cholesterol-lowering capacity. And if you're worried dried fruit may be too calorically dense, the next video Do Fruit & Nut Bars Cause Weight Gain? should help put your mind at ease.

    My whole life has changed since I eat way more and mostly vegetables. Thank you for this info.

      So glad to hear it!

  • invegat

    I have had IBS for over 40 years, I need the natural amount of crude fiber. I get that fiber from 1/4 cup/day Wheat Bran (AKA years ago Miller’s Bran)

  • HemoDynamic, M.D.

    What a Crappy study!
    In a good way.

    3.5 a week?! holy hell.

    It’s true. As a vegan I help keep the toilet paper manufacturers in business.

    • beccadoggie10

      Me, too.

      I used to think I needed dairy yogurt to stay regular, but that was because I did not eat enough fiber in beans and dark leafy greens.

    What study does the 10.9 BM/week for vegans number come from?

    • http://nutritionfacts.org/ Michael Greger M.D.

      Just click on the Sources Cited link above for all the linked citations.

      • Vanillahugz

        Is prune juice just as good as the whole fruit?

  • mgibson

    Invegat……I also was a long time sufferer of IBS…..HIGHLY recommend the book Irritable Bowel Solutions by John Hunter, whose advice has solved my problems.

  • Matt Maggiacomo

    Since going vegan in July, I now have one very smooth, stress-free bowel movement every morning at about 7:30am. Also, thank you so much for these videos. They’ve helped a lot!

  • Editor d

    To quote Anthony Hopkins playing Kellogg in the film Road to Wellville, “They’re huge and smell no more than a hot muffin.” That’s what a plant diet has done for me.

    How many prunes was it?

    • riodreamer

      Yes, I would also like to know how many Prunes a day/week each of the study participants ate?

  • Bruno Lacombe

    Any research on coffee and bms?

    • http://jolkapolkaskitchen.blogspot.com/ WholeFoodChomper

      Yes, I’d be interested in knowing this as well. Eating a mostly plant-based diet and a cup of joe in the morning really seems to help me with regularity.

      • Mirandamom

        Coffee works great for me!

    Everybody poops — we vegans are just better at it. ;)

    I had my 0.9 BM this morning.

  • Kerry

    Stewed prunes work even better!

  • kk

    Thanks. Great video. Was just trying to talk someone out of supplements and into more whole foods. Science always helps.

  • Poohbah1

    Vegans are the shit!

  • LynnCS

    I’ve lived a life of struggling with off and on bad eating habits all while claiming to be a vegetarian. Finally, I made the decision to never eat anything except whole, high fiber foods. No more dairy or vegetarian junk. It’s taken a couple years to go all the way and start to heal a sick gut. It’s working…Yay, Vegan! Oh, and about the prunes. I’ll take them over all the horrible medications any day. Fresh is best.

    So the appropriate slogan might be “At least vegans aren’t FOS?”

    Prunes can be effective for treating constipation but they are inferior to psyllium. Here’s why: (1)Prunes contain large amounts of the cancer-causing growth hormone, IGF-1. (2)Although eating prunes will cause less weight gain than the calories that they contain would predict, they are still extremely high in sugars, extremely high in calories, and prunes will cause weight GAIN, not weight loss. (3)Prunes are expensive compared to psyllium capsules or psyllium powder, which comes in cylindrical canisters. (4)Psyllium has been shown to cause substantial weight LOSS by feeding the good bacteria, reducing the absorption of calories from fats and sugars, and by speeding bowel transit time. (5)Psyllium has been shown to lower colorectal cancer risk in humans by about 20%. (6)Because psyllium is less fermented than other plant fibers, it causes less flatulence than other plant sugars, starches, and fibers. (7)Psyllium is sugar-free and has been shown to be heart-healthy. (8)Psyllium has been shown to work better than docusate sodium, which is what medical doctors still prescribe.

    http://www.ncbi.nlm.nih.gov/pubmed/22863407

    Psyllium works faster for constipation than docusate sodium or prunes because soluble fiber can soften bowels that are already hard. If you need even quicker relief than psyllium, use gum arabic (a.k.a. Acacia Senegal or acacia gum), which is a less viscous soluble fiber than psyllium. However, for maximum weight loss benefit, use glucomannan soluble fiber (from shirataki noodles, konnyaku blocks, or sukiyaki) because it has a higher viscosity than mucilage soluble fiber (psyllium). Diarrhea washes away the weightloss-caising good bacteria and strengthens the weightgain-causing bad bacteria. Acacia gum can easily cause diarrhea. Glucomannan soluble fiber is the least likely to cause diarrhea. Mucilage soluble fiber (psyllium) can cause diarrhea but only if used in large quantities.

      Wikipedia mentions another diasadvantage of prunes.
      Prunes contain substantial quantities of the neurotoxin, acrylamide, which forms in all dried fruits (especially in prunes and in pears) during the drying process with hot air :
      http://en.wikipedia.org/wiki/Prunes

      The Environmental Working Group says that prunes contain more pesticide residues than most other fruits or vegetables:

  • Hawkeye

    How many prunes should one consume dauky?

  • Lovetheanimals

    I’m a vegan and am chronically constipated!!! Eating prunes, kiwifruit, broccoli, and pears (I read these help.) What else can I do?

    • Toxins

      Do you consume whole unrefined plant foods or do you consume processed foods, such as white flour, mock meats, etc. Being constipated as a vegan is quite strange if your following a whole foods plant based diet.

  • Mark Kuntz

    I punch my daily food intake into Cronometer.com and it tells me I get right around 100 grams of fiber a day. I have at least 20 BMs a week. Been a vegan for just over a year and love everything about it.

    • Thea

      Mark: Nice! Thanks for sharing.

  • BettB

    1.7 a WEEK??? OMG those poor people. I can’t imagine. I hope I never find out what that’s like.

  • Gail

    How many prunes are needed daily to be effective ?

  • Lily

    I find that taking freshly ground flax seed, about 1 tablespoon in a small amount of fresh juice or water daily really helps me a lot, and also drinking lots of water. It also reduces appetite by making me feel fuller, so I eat less too!
