Benefits of Brewers Yeast for Diabetes

August 17, 2019

“Benefits of Brewer’s Yeast for Diabetes” In 1854, a case report was published in the precursor of the
British Medical Journal, suggesting 2 to 3 tablespoons
of brewer’s yeast every day could cure diabetes within 6 weeks. But it took another 150 years
before it was finally put to the test in a randomized double-blind
controlled clinical trial of about a half of a teaspoon of brewer’s
yeast a day for three months. What happened? A significant drop in fasting blood
sugars and hemoglobin A1c, as well as an improvement
in insulin sensitivity. What do these
numbers mean, though? Hemoglobin A1c is a measure of how high
your blood sugars have been over time. Under 6 means you’ve been
having normal blood sugars. Between 6 and 6.5 means
you have pre-diabetes, and anything over 6.5
means you have diabetes. Now, you can have well-controlled
diabetes or way out-of-control diabetes, but anything over 6.5
is considered diabetic. In the study, the placebo group started
up at around 9, and stayed up around 9. But the brewer’s yeast group
dropped from 9 to 8. So the placebo group
was stuck up at 9, and the yeast group
dropped from 9 down to 8, so they weren’t cured, but in 3 months’
time, they were able to achieve significantly better diabetic control just eating a half a teaspoon
of brewer’s yeast a day, which would cost about 4 pennies
a day, 4 cents a day. What about for just seven weeks? Again, a total of about a half-teaspoon
of brewer’s yeast a day. Started out with an A1c level of 8. The placebo appeared to help a bit,
but the yeast, even more. From 8 down to an
almost nondiabetic 6.6. That’s amazing; how could it be? Well, the drug industry has
been trying for decades to discover the so-called Glucose
Tolerance Factor in yeast. After all, no shareholder is going
to be happy with a therapy you can buy for only 4 cents a day. We know that whatever it
is in yeast that’s doing it contains the trace mineral chromium. Well, can you just give chromium
supplements alone? Just giving straight chromium does
not appear to be particularly effective. Might the special fiber in yeast,
the beta glucans, play a role? Supplementation with the
amount of beta glucan found in 2 to 3 teaspoons of brewer’s
yeast a day did result in a slimmer waist and drop of
blood pressure within 6 weeks. They trimmed about
an inch off their waist, despite no significant
change in caloric intake. Blood pressures were
significantly reduced as well, an effect also seen
with whole brewer’s yeast. Just a half teaspoon of
brewer’s yeast a day led to a significant drop
in high blood pressure, which, incidentally, is
a key contributor to the cardiovascular and kidney
complications of diabetes.

    Not very surprising since oats contain beta-glucan too and they have the same benefits. Im Italian and I use nutritional yeast sometimes but i eat oats every morning with fresh fruits and nuts… It an awesome breakfast!

    Hi Dr. Greger, thank you for this information and for your work! So what is the recommended amount to take? You mentioned a few different amounts in the video.

  • Reply Rob Williams July 16, 2018 at 2:24 pm

    Couple questions: 1. is there a difference between Brewer's Yeast and Nutritional Yeast? Pretty sure the answer is no. 2. what about sourdough bread? clearly you are still eating yeast when you eat that and recent research shows that the commonly held belief that it is all dead by the time of consumption is incorrect because the loaf continues to get more sour.

  • Reply Rhyothemis princeps July 16, 2018 at 2:27 pm

    I like brewer's yeast for the uridine, which is reputed to have brain health benefits. I stopped using it since it tastes quite hoppy and hops are estrogenic. I don't know if the taste is truly indicative of the hop phytoestrogen content, though. A lot of breastfeeding women use brewer's yeast to encourage breast milk production; it could be phytoestrogens from the hops that helps or it could be the uridine; uridine is found in high amounts in breast milk and not having enough could be an issue in production.

    Does nutritional yeast have the same properties vis a vi brewers yeast?

  • Reply sooooooooDark July 16, 2018 at 3:06 pm

    trying to justify the consumption of brewers yeast as a vegan is like trying to justify "grass fed" beef on some keto blog
    both shiiiiiiiiiat food that just taste amazing
    not sure which of the 2 slows down digestion more

    i bet dr greger didnt type "diabetes + diet" in pubmed (which would be less bias) but instead he typed "brewers yeast + diet" cuz he likes the stuff…i mean come on…i could probably dig out of hundreds of faulty studies showing how good fish omega 3 oil alledgedly is

    really hate the reductionism that science does sometimes…

    Brewer's yeast is what I use as my protein shake mixed with beets moringa cinnamon and almond milk. I would encourage all to look up this superfoods on

    The minerals including chromium and various other cofactors. It antiestrogenic and carb to protein ratio is right for various conditions.

    If simple brewer's yeast could do that, then wildcraft Ling Zhi mushroom (ganoderma lucidum) would probably nuke type II diabetes once and for all through the normalization of metabolic disorders.

  • Reply Peter Faber July 17, 2018 at 12:05 am

    Oh come on. No explanation of how this works? Just some vague suggestions?

    Yeast feeds of sugar, so less of the sugar you eat ends up in your blood?

    Brewers yeast is a probiotic.

    Which is so cool. It means that glucose controll improves with less glucose ending up in your blood.

    So,….. give it a try,….. You can do it, reach the conclusion,……..The cure for diabetes is,…… No glucose ending up in your blood!

    Low carb is the cure for diabetes!

    Type 2 is a joke – simply start fasting, eat one organic meal a day and you will be cured in 8-16 weeks. Or use the Snake Diet to ease your fast. Done and done!

  • Reply Joe R July 17, 2018 at 3:58 pm

    Interesting report. I have a little nutritional yeast everyday, itty bits, adding up to about a teaspoon for the day, helps curb my appetite. I like the cheesy and nutty taste. I’ve noticed that my fasting blood sugar has gone down a fair bit, from 140-150 to 120 and even 107 the other day. But hadn’t made the connection, assuming there is one (Dr. Greer is talking specifically about Brewer’s Yeast, not Nutritional Yeast). Maybe there is no connection, but again interesting. This is a good reason to keep a food journal.

  • Reply SunkenReX July 18, 2018 at 2:04 am

    I wonder if it's the body's immune response playing a role. Many people actually have brewer's yeast antibodies. Perhaps the presence of yeast keeps the body preoccupied in some way that affects its ability to respond negatively to insulin.

    If you applied all the suggestions, no oils, no dairy, no animal proteins, etc. and added all the foods, Amla, brewers, herbs and spices, vinegar, and ate all suggested, your diabetes should be reversed, but is it? I have been doing this for over 2 years, modifying my intake as new videos come out. I'm not cured of this condition. I do believe that low carb is the solution. That doesn't mean eat all the bad either. I eat mainly Tofu, massive veggies, legumes, beans especially, in limited quantity which is a can a day, and berries and some other fruits in limited quantity, which is over 2 cups a day. Also intermittent fasting helps. Dr Hans helps. Dr G helps. Dr furhman helps. But so does Jeff Cavalier and Bob and Brad physical therapist online. I'm now well within the BMI and my body fat % is well better than 95% my age and so is my physical activity and appearance and muscle tone and composition. My vitals all exceptional other than my diabetes. Some are blessed to recover on just sitting on the couch and eating vegan, but for me, in two years, I have not been able to get my A1c to 6 with activity, food consumption, and massive r&d as I call my daily path to super health. I started this path 2 years ago because my doctor wanted me to go on insulin. How could someone that appeared in great shape and condition be asked to go on insulin. That's when I found Nutritionfacts and all the other good doctors mentioned above. So what changed? My diet to vegan. My workouts and recovery totally enhanced by the physical therapists videos online, by enhancing my cardio and workouts and recovery. Eating more bean than 10 humans (idk if this is accurate but I eat a lot of black beans and all kinds of beans) eating more blueberries than 10 humans (again idk but it's a lot), and only eating 2 meals out on the weekends which are my only two meals for the weekend. This dropped my weight to well within the BMI and my vitals better than an aviation pilot. I'm healthier yes, look about the same physically but in a smaller proportion, but my diabetes is still not cured but much better. I don't know how much more I will adjust, but I know I can adjust and will adjust when new things come up in my R&D.

  • Reply vacadreamer January 25, 2019 at 6:49 pm

    I decided to give this a try…got to believe in something that helps! Started with A1c at 7.7 Used 1/2 teaspoon of brewers yeast 6/7 days a week mixed into salad or other foods(it tastes AWFUL by itself) There were days that I did not take it due to travel, etc. Six months later I had a complete blood panel…results floored me. Without changing diet or alcohol consumption(couple of glasses of wine here and there) my A1c dropped from 7.7 to 6.5 and my blood sugar dropped from 168 to 142. Lots of better readings as I have begun to change my eating habits and lifestyle. Michael Greger-you are a good source of truth!
