I can’t afford concierge healthcare, but I sure appreciate all this Free education you, Mary and Heather give Everyone on Sunday nights and via your website and books.
Thank you!! 💜🙏
I take B12 and have for years at the recommendation of Dr. Mcdougall, thanks! I read a Consumer Reports article that there is lax regulation of supplements in this country but they recommend finding supplements that are tested by certain independent labs, and I found one version called Nature Made 2500 mcg B12 that is approved by USP. The article that discusses these independent testing and how to find the supplements is called "How to Choose Supplements Wisely". I am happy so far with my choice. I take 1 pill a week.
Thank you Dr Mcdougall. For every thing you have done for humanity all these years🙏🏻🙏🏻🙏🏻🙏🏻
I'm following your sharing on B12.....l am now taking it as recommended. And sunshine for V-D. And l had a good clean Mexican plate for Cinco de Mayo. And while l'm watching this rerun because l got busy during your live..... l'm having a bowl of white steamed rice with veggies
Dr. McDougall is amazing!!! Thank you a bunch!
I took a stomach acid reducer for about a year, and ended up with B12 deficiency. I'm on a supplement now.
Thank you for all of the information. I love listening and learning. Blessings.
You both look amazing and thank you so much for having these sessions with us! I personally appreciate it very much!❤
I forgot to mention Heather she is a real cutie and such a great host!
Thank you for the wonderful books!
Stage 3 colon cancer question - I want to tell you - make raw cabbage, carrot, apple slaw (dressing of fruit and vinegar blended) a regular part of your diet! Add it to your lowfat McDougall diet. About a pound or two of that salad per day is what I would eat if I had colon cancer.
Go Carnivore
Is sulforaphane also good to fight colon cancer? You can find research on internet, You Tube, and articles on cruciferous vegetables.
You could sprout organic broccoli sprouts weekly.
Directions on internet and look up Dr. Jed Fahey- former researcher of this at Johns Hopkins.
Stage 3 Colon question: Best wishes to you- and if you go plant based or not… please keep us posted if you can? I’m of the belief that going plant based can slow cancer growth, even if it doesn’t cure it alone. All my best to you!
Did you watch chrisbeatcancer on youtube? He had stage 3 colon cancer in his late 20s and got rid of it through raw plant exclusive diet and without chemotherapy, as he was aware that chemotherapy is what kills you, as it destroys the immune system.
@kenwang9672 Carnavore not a sustainable solution at all! It may help for a few years , but shit happens after we reach a 5 or 10 years at the max. I'm 83 years old, no doctors, no meds, still running around like a healthy teenager while my classmates are all dead or bed ridden using a bed-pan. Thats likely to be most people's future because of extreme unhealthy unsustainable diets.
I have eaten like my Gandparents ate down on the farm 120 years ago... Fresh and chemical free!
Yeah!! Fresh for the win!!
A common form of vitamin b12 supplement is partially derived from sewage sludge...
1. Title: Vitamin B12 production from activated sludge by Propionibacterium freudenreichii
Authors: Fujita, Y., Ito, T., Nishiuchi, H., & Takenaka, S.
Publication: Journal of Bioscience and Bioengineering (2019)
Quote: "Activated sludge is a potential source for vitamin B12 production."
2. Title: Vitamin B12: Advances and Insights
Authors: Ganesan, B., & Brothersen, C.
Publication: CRC Press (2019)
Quote: "Industrially, vitamin B12 is produced through the fermentation of certain bacteria, including Propionibacterium species. One of the substrates used for this fermentation process is activated sewage sludge."
Not related to this, but going off the live chat. Maybe you should watch dr. Peter Rogers 30 point checklist on how meat helps cancers grow. Not all data on meat is confounded, do you really think the WHO would mark it as carcinogen if there wasn't a problem? Besides the high protein count of meat, it also has a lot of fat making our blood thick and our blood cells rigid.
@@11235Aodh Peter Rodgers doesn't give viewers studies to go check out for ourselves.
Here's 10 studies showing 1 molecule found in red meat having anti-cancer effects...
Anti cancer promoters: meat and milk of ruminant animals
Here is a summary of ten research studies on the anti-cancer benefits of trans-vaccenic acid (TVA), a naturally occurring trans fatty acid found primarily in ruminant-derived foods
1. **"Trans-vaccenic acid reprograms CD8+ T cells and anti-tumor immunity"** by Bose et al. (2023)
- This study found that TVA improves the ability of CD8+ T cells to infiltrate tumors and kill cancer cells. Patients with higher levels of TVA in their blood responded better to immunotherapy, suggesting TVA could be a nutritional supplement to complement cancer treatments.
2. **"Trans-11 Vaccenic Acid Has Anticarcinogenic Properties in Experimental Models"** by Banni et al. (2001)
- The researchers demonstrated that TVA inhibited the growth of mammary tumors in rats, indicating potential anticancer effects.
3. **"Vaccenic Acid Feeding Increases Tissue Levels of Conjugated Linoleic Acid and Suppresses Development of Premalignant Lesions in Rat Mammary Gland"** by Lock et al. (2004)
- This study showed that dietary TVA increased conjugated linoleic acid (CLA) levels in rat tissues and reduced the development of precancerous lesions in the mammary gland.
4. **"Trans-11 Vaccenic Acid Reduces the Risk for Experimental Colitis in Mice"** by Jaudszus et al. (2012)
- The authors found that TVA supplementation reduced inflammation and the risk of colitis in a mouse model, suggesting potential benefits for gut health and cancer prevention.
5. **"Vaccenic Acid and trans Fatty Acid Isomers from Partially Hydrogenated Oil Both Adversely Affect LDL Cholesterol: A Double-Blind, Randomized Controlled Trial"** by Gebauer et al. (2015)
- While this study found that both natural TVA and industrial trans fats increased LDL cholesterol, it highlights the need to distinguish between these sources when considering health effects.
6. **"Trans-Vaccenic Acid Is Converted to Conjugated Linoleic Acid in Mice"** by Santora et al. (2000)
- The researchers showed that TVA is converted to CLA in mouse tissues, which may contribute to its potential anti-cancer benefits.
7. **"Trans-Vaccenic Acid Is Desaturated to Conjugated Linoleic Acid in Mice"** by Turpeinen et al. (2002)
- This study confirmed that TVA is converted to CLA in mouse tissues, supporting the potential health benefits of TVA through its metabolic conversion.
8. **"Trans-11 Vaccenic Acid Reduces Hepatic Lipogenesis and Chylomicron Secretion in JCR:LA-cp Rats"** by Wang et al. (2008)
- The authors demonstrated that TVA reduced liver fat synthesis and the secretion of lipid-carrying particles in a rat model of metabolic syndrome, which may have implications for cancer prevention.
9. **"Comparison of Conjugated Linoleic Acid and Vaccenic Acid in Milk Fat of Sheep, Goats, and Buffaloes"** by Mele et al. (2009)
- This study analyzed the TVA and CLA content in milk from different ruminant species, providing insights into the variability of these potentially anti-cancer fatty acids in dairy products.
10. **"Trans-Vaccenic Acid Has a Higher Bioavailability than cis-Vaccenic Acid in the Rat"** by Chardigny et al. (2003)
- The researchers found that TVA had a higher bioavailability compared to its cis isomer, suggesting that it may be more effectively absorbed and utilized by the body for potential health benefits.
These studies collectively suggest that TVA, a naturally occurring trans fatty acid found primarily in ruminant-derived foods, may have anti-cancer properties related to immune function, tumor suppression, and metabolic conversion to CLA
Thankyou Dr mcdougal the original sos doc
Thank you!
Was that man who died were they vaxxed
More carbs more life quality!! Nothing better then low fat high carbs diet for athletic performance, Carbs FTW💪💪
How did someone just run 5 marathons in a row in a fasted state 😂
What an episode. Love this series so much.
Thanks for reminding me to take my daily pill.
Eating 90% potatoes this week and my gut feels great. I am excited to watch the gut health live!
I get B 12 from fortified nutritional yeast. I can control the amount to be very small and use weekly.
I personally use the Pur *"Plus"* water filter. (Not to be confused with the Pur filter!) I have the 30 cup dispenser, in my fridge. And.... dinner tonight was 8 cups of cooked white jasmine rice, 2 pounds of orange sweet potatoes, and a crown of broccoli.
How many cups is that in the measuring cup before you cooked it? Do you actually measure how many cups it is after it's cooked? I'm guessing that you don't. It makes more sense to me to say how many cups it is before you cook it.
I typically eat 4 cups precooked in one meal.
@@dj-fe4ck 16 ounces raw rice, my typical serving. I weigh it before I cook it, because cup measure is too variable. Total calories about 2500.
@@dj-fe4ck I usually eat nothing but nonstarchy veg during the day, and satisfy my hunger drive with one large starch dinner at about 6pm.
I don't believe you.
Vitamin B12 bioavailability from food sources:
Title: Bioavailability of vitamin B12 in meat
Authors: Gille, D., & Schmid, A.
Publication: Nutrition Reviews (2015)
Quote: "The bioavailability of B12 from meat is estimated to be approximately 60%, whereas 60-70% of the daily intake is believed to come from meat and fish, showing the high bioavailability of B12 from these sources."
Title: Dietary sources of vitamin B12 and their association with plasma vitamin B12 concentrations in the general population: the Hordaland Homocysteine Study
Authors: Vogiatzoglou, A., Smith, A. D., Nurk, E., Berstad, P., Drevon, C. A., Ueland, P. M., Vollset, S. E., Tell, G. S., & Refsum, H.
Publication: The American Journal of Clinical Nutrition (2009)
Quote: "The bioavailability of vitamin B12 from meat is estimated to be 60-70%, which is higher than that from eggs (20-25%) and fish (25-30%)."
Vitamin B12 bioavailability from supplements:
3. Title: The bioavailability of vitamin B12 from two different sublingual dosages
Authors: Sharabi, A., Cohen, E., Sulkes, J., & Garty, M.
Publication: British Journal of Clinical Pharmacology (2003)
Quote: "The absolute bioavailability was found to be 7.7% and 12.6% from the 100 μg and 500 μg doses, respectively."
Title: Bioavailability of vitamin B12 from a new high-dose oral vitamin B12 formulation
Authors: Delpre, G., Stark, P., & Niv, Y.
Publication: Journal of Clinical Pharmacology (1999)
Quote: "The mean bioavailability of the vitamin B12 from the oral preparation was found to be 1.2%, compared with the IM vitamin B12 injection."
These studies suggest that the bioavailability of vitamin B12 from red meat is generally higher (around 60-70%) compared to the bioavailability of vitamin B12 from oral supplements (ranging from 1.2% to 12.6% in the cited studies).
It may be more bio available in red meat but it’s a low concentration to begin with like 2.4 μg Per serving. So even if a supplement is only 1% bio available then a 500 μg supplement would be 5 μg Available which is more than twice a serving of red meat. Context is everything. If your concerned about b12 levels a supplement is the obvious choice! 🙏🖖
Who care as long as it's working and we still manage to get a good b12 level. Food is a package deal you have higher bioavailability for B12 but also all the negative aspects of meat. Also 33% of meat eater are still b12 deficient cause in animal products, vitamin B12 is attached to a protein, and as people get older, production of the stomach acid that can split this complex of vitamin B12 and protein diminishes.
The higher the dose the lower the amount is absorbed: the amount from very large supplements is still very high. Supplemental B12 is absorbed better than from foods.
Not sure why I had to add my home address to get a digital download. Please explain!
?? Does the intrinsic factor decrease with age?? For B12 absorption?
I hear that soy, flax seeds and too many cruciferous vegetables can block the absorption of iodine by the thyroid. I work hard to make sure I get 150 mgs of iodine daily- cuz my TSH went up when I overdid the 3 foods above for a year. 🥴
I just take an iodine supplement. I take 250 mcg iodine two times a week.
Can you reverse blockages in your limbs with this way of eating? Also, I'm a bilateral amputee.
My husband had a turp surgery. It helped him a lot. He was getting to where he could barely pee. Now he has good flow, but doesn't pass semen with ejaculations, but no biggie.
Bottled water is a big source of microplastics, better that people get an osmosefilter as dr. Peter Rogers recommends.
Title: Bioavailability of Nutrients from Foods and Supplements: A Review
Authors: Comerford, K. B., & Miller, G. D.
Publication: Nutrients (2021)
Quote: "The bioavailability of nutrients from supplements can vary widely and may be affected by factors such as the form of the nutrient, the presence of other compounds in the supplement, and individual physiological factors. The RDI values are based on the assumption of average bioavailability from dietary sources and may not always reflect the bioavailability of nutrients from supplements."
Is there any good material on mild subclinical B12 deficiency? I.e maybe just a mild anemia and slight tiredness? I suspect that I might have had a very slight subclinical deficiency like that, which I assume because I had some instant slight improvement in how awake and fit I feel, when I started taking a daily low dose B12 ca. 1 month ago.
You should get your B12 levels tested.
@@ianbryantNow, it definitely couldn't tell me anything useful anymore. The only obvious proof of deficiency is anyway, that you improve right when you start the supplementation.
I take my B12 once a week and even at that it's over a 12 on my test so I'm more than covered
How much do you take per week ?
What does McDougall think about Russell Blaylock and a excitotoxins???
How does this keto diets harm the body? Most don’t eat any carbs. Ty, Doc!
keto is dangerous you missing 17 essentials micro nutrients
its bad for your heart, bad for your gut microbiome ( doi : 10.1038/nature12820), you losing muscle and bones

Question are you still able to ejaculate after prostate radiation I’ve had it done in 2023 from March until May for 44 treatments and the treatment sure about a minute or so and I’m still OK I’m still producing blew it but my sperm is not milk away anymore it is a clear septage from my understanding it kills the fluid from the prostate however the fluid from the testicles and the seminal vesicles are still active so during sex I can still climax but I’m not sure if I can Prague Nate a woman anymore So this is my question for you your listener Robert Albitre
They want the jingle in your head! So funny. But don't they!
Mary you always stay so slim and beautiful. About how many calories a day do you eat to stay that way❤
Dr Mcdougall has said she eats between 1400-1500 calories.
Eating the correct diet means that the weight drops off you and stays off you. Obviously you need to continually eat that way but you have no cravings being plant exclusive and no health risks like you have with carnivore and keto. One of the doctors on youtube lost his keto friend a couple of months back aged 45 to a massive heart attack. Was keto for 2 years.
Dr mcdougall, the speaker in this video had a massive stroke at age 18 from eating the meat and dairy on his parents farm.
What you eat is more important than the calorific value
Hello, any suggestions for gastroesophageal reflux with diet, in order to avoid ingesting the medication OMEPRASOL.
Is B12 made by all bacteria or just by specific bacteria?
I get a rash around my mouth when I take B12, I don’t know what to do.
You are getting enough.
Do you have to eat a lot of calories to meet all the amino acids ? Seems like it takes a ton of plant foods to get all the protein
He have a Masterclass about protein. We don't need much vegans get as much as omnivores and the excess protein is converted in glucose or fat.
It would be extremely hard for even a registered and skilled dietician to make a diet of healthy plant foods only, with sufficient calories, that didn't have enough complete protein. But if you want to have proof just use cronometer to count amino acids in your foods.
Not all foods in the cronometer database log all the amino acids, though. I have a whole wheat pasta that doesn't log them. You might have to check that the first time you enter a food.
@@RiDankulous vegans get the same level of protein as omnivore
It depends on how active you are,if you do light activity all day then you wont have to eat as much but you wanna atleast have a meal with enough calories 200 or more.
As for me once I hit the ground running and I got duties for the day that requires walking back and forth or lifting some heavy objects then I wanna start with like 300 calories a meal then i am good for a while before I can eat again.
At the end of the day have another meal after dinner,just before bed have some fruit.
You have to just come up with about 6 diffirent foods you like and make enough to keep in fridge or in your lunch box.
Rice and beans are a complete protein,you can also argue that but you can live off of potatoes,I did it for months.
Mixed veggies,broccoli,pasta,potatoes,beans,rice,there's alot other kinds of starch to choose.
If you wanna lose weight fast then you wanna eat lighter calories,more salads and fruit.
Increase your normals activety to boost the metabolism,early to bed,early to rise.
It’s not easy being Green! Lol
I thought the common knowledge was that the b12 in seaweed is an analogue which can stop your ability to absorb active b12? Id rather not ruin my genetics by taking b12 supplements, id rather do the opposite and push my genetics to be more efficient with the b12 it has.. but dr greger stresses that its VITAL that we take b12? It bothers me that i feel like the only person who thinks not just about my own health but also my future generations, do we really want to evolve to rely on labs for b12 supplements? Or do we want to evolve naturally.. this has been the hardest part about being vegan for me, it bothers me so much.. i feel irresponsible as someone with strong healthy genetics, especially taking information from a bald guy with glasses who probably looked 50 when he was 20.. i feel like the only person that is so bothered by something so fundamental. He even says we need to take 1000mcg a day after 65.. i follow his recommendations.. but it really does sicken me to the core
He's making sure people with direct absorption problems and/or other relevant prexisting conditions are covered - as Dr M himself points out in this talk.
Most people need not worry, if they just take occasional supplementation, and/or fortified foods.
It's sad we have to supplement, but that's because we can't drink steam and river water (now polluted) that contains the B12 bacteria. Also, less likely, but perhaps, also over sanitation of fresh and frozen produce today.
The very fact we need such a small amount, compared to carbohydrate, protein and even fat levels, suggests we did evolve/were created in a vit B12 poor environment.
E.g. a whole food places based/starch dominant environment :)
This is the difference between being plant exclusive or vegan.
You have a mental illness to be thinking the way you do. Get rid of the processed crap and see the difference.
As chef AJ says, you're majoring in minor things. Needing to take a supplement to prevent irreversible brain damage is nothing in the scheme of things.
Dr. Greger also likely looks the way he does because of genetics. You really need to improve your outlook. Your negativity is horrendous.
It's only a problem with nori and spirulina not with supplements. 33% of meat eater are still b12 deficient cause In animal products, vitamin B12 is attached to a protein, and as people get older, production of the stomach acid that can split this complex of vitamin B12 and protein diminishes.
Science is not a beauty contest and a study sample with just one individual would be insignificant.
If you didn't sequenced your all genome you can't really tell if you have good genes
@@wellthi sequence your genome? Your telling me you've never seen somebody with good genetics.. good looking tanned great personality good at sports and never has any health problems.. I put it down to being mixed race and my ancestors living completely from the land only 200 years ago
@@veganchiefwarrior6444 your ancestors did't live in this polluted world with all that junk food.
