- เผยแพร่เมื่อ 12 ก.ย. 2024
- Zoe Harcombe challenges the prevalent belief in the necessity of dietary fiber, arguing it's a non-nutritive waste product our bodies cannot digest. She questions the widespread promotion of fiber intake, citing historical misconceptions and a lack of evidence for its health benefits, and discusses studies showing the elimination of fiber can resolve many gastrointestinal issues.

I was always plagued with hemorrhoids when I was on the standard western diet ( I ate tons of fibre ).
You just assume hemorrhoids are normal as you age.
Since changing to a Keto/carnivore diet all hemorrhoids have gone completely with no re recurrence.
Same thing happened to me when I went carnivore, what a relief!

A health practitioner said to me yesterday we need fibre to get our digestion moving through. I said, high animal fat can do it better.
Both work!
@@thiagolusvarghimd I agree both work, but she didn’t know that. That’s my point.
Zoe Harcombe is such a great speaker and her message saved me from terrible constipation. I'm a bit sad that I suffered for years following doctor's advice to eat more fibrous plants and that the mainstream narrative is still to eat more fibre for gut health.
She is great! Everyone is slightly different. You have to try different approaches until you get the result you desire. Thanks for watching.
Everything Zoe says is GOLD. Thank you Zoe for being so reliable and dependable. Your information is GOLD and you are my favourite. 81 year old female in Australia
I completly agree with the doctor. I have/had refractory celiac disease with gastroparesis, Gerd, and colitis.
I am eating just meat and fish and through this step I am not longer suffering physically.
They wanted to be assisited by a dietician for disorder eating.
It is a total madness in the medical system.
I’m glad you’re feeling better. Good job on taking control of your health.
This diet was exactly what my mother was told in the early 1950's by doctors at a former US army hospital in Oxford, UK. She had ulcerative colitis very badly and was regularly in hospital for months at a time until this point having blood infusions etc to keep her alive. She kept to a lowish fibre diet all her life and lived to be 98.
She also helped my father who developed colitis in old age in the 1980a when was prescribed a high fibre diet which made him worse. She fed him low fibre food and he recovered. Note she was also treated with the newly discovered drug cortisone at huge expense to the newly formed NHS.
I’m 75 years old. I’ve been on the Kaba lifestyle for almost 5 years years. I am going through different healing programs within myself. My brain is getting more grounded and clear. My muscle tissue has enhanced. I wore glasses at 40 years old. My eyes are back to almost perfect vision. I seldom need to use a Magnifier to read anything I wish I knew about this at young age. My experiences in life would’ve been completely different. I hope you consider trying it for at least 60 days. I can’t believe that I’m still getting more enhanced as time goes by, my physical structure has gotten stronger and quicker and more flexible. Good luck with your life.
Thank you Dr. Zoe for speaking the truth to these people who still think fiber is helpful. I have diabetes and the absolutely worst "fiber" for me iss rolled oats. It is a killer.
Rolled oats is a grain. Oat bran is the fiber. Oats are heavily sprayed with chemicals, which are the killers-- not the oats themselves.
For a diabetic, oats is deadly. enough said.
@@Cher1924 Diabetes is deadly. Be careful with the ideas you tell yourself, because belief becomes a self-fulfilling prophecy. If you eat an oatmeal cookie, your glucose will spike. It will also spike from eating fruits, veggies, grains, and even meat. Different food combos will elevate glucose through the roof. Hating on silly rolled oats misses the point of how to reverse diabetes.
I've always had difficulty with regularity, might be more about early upbringing, parents always fighting and outside toilets, freezing in winter I've tried the fibre and Brown bread just bunged me up more. At the age of 75 still not totally regular but still fit and healthy. I've lived a life of taking laxatives about once a week with no serious harm yet.
Yet again we are lead to believe that once a day is the norm but I bet there is a high percentage that dont.
You're right. Once a day is not what every person experiences. As long as it is regular and once every couple of day without pain or lots of straining then that should be good. "Normal" is the baseline of each person. To some people their 'normal' is once or twice every 3 days. Others, it's 2-3 times per day.
It’s great when a respected doctor backs up what I’ve been saying for YEARS to my own patients
Where is the respected doctor there's only somebody with a bought PhD here with no nutritional background or science background
Someone like dr. John mcDougall or dr. Dean Ornish, or dr. Caldwell Esselstyn?
Which "respected doctor" are you referring to?
@@11235Aodh those people aren't respected and they look like walking skeletons. They are not the picture of health at all
but I really do want Internet over Fiber Optic cable.
😂
Carbon fibre is so expensive
I eat natural fiber everyday. Not in large amounts but my gut microbes thank me and I'm regular.
Great! I still eat fiber and have no problems either. It good to know that people have options and can change their diet until they get results.
I eat meat and lots of it. Regular as well
So interesting! I never heard this before....going to have to experiment. 😊
I don’t think Professor Tim Spector would agree, apart from the fact we can’t digest fibre, but our gut microbes do & that’s what feeds them & they’re very important for our health. It would be good to have Zoe Harcombe on the Zoe podcast but that’ll never happen because she challenges their narrative! I get the “waste product” bit but I’m dubious about zero fibre. I certainly don’t eat 30g a day but I do have some. Very interesting about white vs wholegrain. Trouble is we’ve been fed (no pun intended) so many lies about diet over the years it’s hard to know what’s right. I think you have to find out what works for you as an individual. Limit UPF, get rid of seed oils & artificial sweeteners for sure. But there’s no “one size fits all” in anything. BTW she’s not a medical doctor, she’s a PhD, Cambridge University graduate with a BA & MA in economics/maths whatever that actually means. That’s not a slur, I genuinely don’t know!
You’re correct, Typically people who have harsh issues are probably eating too much fiber and could have seriously intestinal issues that should be addressed.
What about the gut bacteria using the fibre to make Short Chain Fatty Acids - which are used in lining cells and taken into the body Surely that is beneficial?
Interesting study re fibre and reduction in Colorectal cancer
www.ncbi.nlm.nih.gov/pmc/articles/PMC10488173/#:~:text=In%20fact%2C%20fiber%20is%20involved,growth%20%5B15%2C27%5D.
I had chronic ibs and gastric reflux my entire adult life. Terrible pain. I went, at 63, Carnivore diet. All my lifelong gut problems disappeared completely in the first week. Ive been eating carnivore for 10months, zero sugar, zero carbs, zero plants, zero processed foods, zero seed oils, zero fibre. Im off all my heart meds. My blood pressure is 15points lower without meds than when I was on meds. My mental and physical health transformation is something I still find startling. I effortlessly lost 75lbs, cured arthritis, ibs, gastric reflux, depression, anxiety, prostate problems, joint pain, sleep apnoea, inflammation, t2 diabetes, and a host of other things. I'm back in the workplace now shaming guys half my age. My testosterone is through the roof. Im never hungry, never tired. All i eat is beef, butter, bacon, eggs. Who knew.
@@johnallen7367 I'm very pleased it worked for you - not something which would suit me though. Still interested to hear about the microbiome and Short Chain Fatty Acids.......
Fatty acids, that's what animal fat is for, your brain needs it. Fibre is waste, avoid it.
uhmm no we are not cows, we are lions.
Unfortunately it’s bad for business
Why the subtitles in the same language you are speaking?? TH-cam has a good translator and you are ruining it for non native english speakers...
What if you're Diabetic? I started taking soluble and insoluble fiber and it's been great for me over the last 12 months, along with eating more nuts, seeds, and berries.
If it's been great for you then keep doing it! No need to change what is working.
The microbes in our intestines produce short chain fatty acids and butyrate when they digest the fibre we eat and these by products are used by the body. They also help regulate and monitor gut health. If anyone is having problems when introducing more fibre they should consume small amounts and increase slowly so that sufficient amounts of the required gut bacteria can grow.
To say that we don't digest fibre so we don't need it is plain wrong.
You can get Butyrate from Butter
If we "digested" it, it wouldn't still be there, it's a waste product. My life is improved a thousandfold since getting rid of it. I no longer spend my life in the bathroom. Nonstop gas meant I couldn't do my job. no more bleeding in discomfort. Ketones are the answer to your question
Proud you are digging gor the Truth
Fibre does nothing to me but more constipation I just don't need it
One says this and the other one says that. You can eat anything in moderation.
good luck!
You might want to reconsider that "anything in moderation" statement. You're saying poison, toxin, alcohol, drugs, poop, etc are okay in "medium" amounts. If your body isn't meant to have certain things fed to it, how do you know how much you should be forcing it to tolerate? You may not die immediately, but there will be consequences down the road.
Only if you are someone who is a moderator. Not everyone is a moderator some people have to abstain completely
“You can eat anything in moderation”, I fully disagree.
Thousands of people are turning to carnivore because we can’t tolerate even the smallest amounts almost any plant based foods without suffering painful/inflammatory results, even if we start small & increase over time. In the end a lot of us would rather choose a life of physical comfort & limited variety, rather than trying to eat things that others expect us to eat, only to suffer the consequences for days later.
“One says this and the other says that.” Yes, people in power lie for their own benefit all the time & their lies get perpetrated until they are believed as truth... It’s very time & energy consuming to go digging through all the “this & that’s”, but that is exactly what Zoe Harcombe has done, she has spent thousands of countless hours reading through articles, studies, journals , etc, following the threads back to their origins, & so she is sharing what she has discovered… I’ve been doing my own digging for the last couple of years, & it has really opened up my eyes to the bullshit that they feed us.
Good luck @comancheflyer4903 I hope you seek for & discover the truth 🤟🏻✨
Hello for East Tx++++GO Carnivore for LIFE!!!==Marvin
Has she ever heard the word "microbiome"?
I’m confused because white rice and pasta is processed which Zoe doesn’t encourage. Is this simply for people who struggle with fibre?
The simple issue is; fibre is pointless, indigestible and counter productive.
@@johnallen7367 I agree…for many people with already compromised bowel health issues. But I can’t get my head around Zoe’s rigid belief that zero fibre is an across-the-board good thing. We’ve adapted for millions of years to have an intake of some fibre (A little, or a lot in certain parts of Earth). It seems very counter-intuitive.
@@stevelanghorn1407 hi. 10months ago, at 63, i was fat, sick, on heart meds. I went carnivore diet. Apart from losing 75lbs effortlessly, i cured my arthritis, ibs, gastric reflux, depression, anxiety, prostate problems, joint pain, sleep apnoea, inflammation, t2 diabetes. I have had zero sugar, carbs, processed foods, seed oils, fibre. I kicked all my heart meds. My transformation has been startling to me. My testosterone is through the roof, my mental and physical health is extraordinary. I keep having to buy new clothes. My pants were 42, now im 34. Women are flirting. Im back in the workplace. Remarkable.
@@stevelanghorn1407 We've consumed fibre for only 10,000 years, an insignificant period in evolution. It's counter intuitive to not be on a meat diet.
@@What-The-Beef And where did you pluck that date from? A carnivore TH-camr per chance? We evolved for millions of years eating meat, fish…and (sorry to throw a spanner in the works) some plants.
The study she refer to I like to see vs she takling x study only.
Excellent!
IF this is TRUE, The Medical Professionals are absolutely shit except a very very very honest few.. Wow, Thanks been on a research journy for Carnivore now 3 weeks.. about 60 hours worth of videos. I Wish someone would capture all the success stories, healing, uncrippling, etc etc of people going to total meat, catalog them an write a book on it. AMAZING, then you have Doctors saying its B.S. Obviously works for almost all that try it. My problem so far is its boring as hell but the grocery shopping is EZ as hell. MEat dept hear I come!
A lot of youtube video comment sections have great testimonials, unfortunately, those aren't enough to sway the medical guidelines. That's why it helps when people make change in their life, get results, and show their doctors.
Someone is capturing them! His name is Dave Mac and he has a channel called No Carb Life
@@sparklemotion86 Thank you for this!!!! I went an I had already watched some of his content. Did not realize this was the basis for it... Ill pay more attention to it.. God Bless..
Thiago sounds very hesitant
So fiber is useless. But it it harmful?
I'd say it's definitely harmful for some people! No more gas, bloating, diarrhea, bleeding, since I cut it out!
Please don't get influenced no body knows anything about your body. You know your body best. This about diets is so stupid just remove ultra processed food everything else. Fibre is for your microbiome. There are people who I know have improved with it, there are who haven't. We are all biased. Be smart and do what is good for you. Don't listen to anybody.
FIbre makes ess. fats in Col0n, or am I wrong or is she wrong?
You have a small capacity to make short chain fatty acids from fibre. Your body can also get short chain fatty acids from ketones.
Butyrate is made by beneficial gut flora after they consume undigestible fiber, not from the fiber directly. When I consume fiber (but not grains) I am free from hay fever symptoms.
People aren't termites.
How can she be a Dr. and not know that our micro Biome in your stomach depends on that dietary fiber to feed on, this bacteria in your gut is a huge part of your immune system that defends your body from disease and protects your stomach’s mucous lining and also keeps bad bacteria in check.
She addresses that on her website. I might bring her back to talk about that on the podcast though.
@@Bob-67she's a scientist that has studied this. That's how she knows. Phd still means dictor and still means having studied something new. What's your phd in?
your stomach fills up with stomach acid ... what microbiome is there in your stomach? If you spilt the acid from your stomach on your skin you would get a nasty acid burn.
@@Bob-67 PhD makes her one and she does scientific research. That makes her a scientist. If you did any research following the scientific method as does she, you would be on too even if you have no titles.
So again, whats you PhD in?
She has actually done research on this subject. Have you?
@@TheCompleteGuitarist the natural bacteria thrives in that environment and protects the mucous lining in your stomach, that’s the reason the acid doesn’t harm the actual stomach. That bacteria is the majority of your immune system and it communicates with your body and brain to defend your body from bacteria and viruses.
Hang on: Fibre is not 'a waste product', no more than water is, and yes the body can't digest insoluble fibre, but does it not feed the microbiome?
Yes Zoe is a quack
It does, i rather listen to dr. John mcDougall and dr. Peter Rogers who actually discuss the science at hand. When you don't eat fiber your microbiome will start eating away at the mucus layer protecting your blood vessels from the stomach contents.
The macrobiome can easily adjust to meat and other animal food, fermented or not. Give it a little time to transcend and all will be fine. Carnivore heals.
@@billythekid2324 Carnivore heels are made of gout. You need fiber so your microbiome doesn't start munching away at the layer of mucus protecting your blood barrier.
@@11235Aodhdo you have a research for this claim?
The good gut bacteria needs fiber.
Then what does it feed on?
@@Jay37_bakeso microbes now eat butyric acid do they? 😂 You're worse than Zoe
@@Jay37_bake That's not that they eat, the butyric acid is there because the microbiome of the cow has made butyric acid from the grass. It's what these bacteria do, they also make buturic acid from the fiber we eat. "Commensal bacteria such as butyrate-producing bacteria can ferment undigested carbohydrates to produce small molecular metabolites such as lactic acid and SCFAs in the intestine, promote the proliferation of beneficial intestinal bacteria such as bifidobacterium, lactobacillus and fecal bacillus, and inhibit the growth of pathogenic bacteria such as Staphylococcus, Escherichia coli, Salmonella typhus and Clostridium difficile" www.ncbi.nlm.nih.gov/pmc/articles/PMC8465514/#:~:text=Commensal%20bacteria%20such%20as%20butyrate,bacillus%2C%20and%20inhibit%20the%20growth
Some bacteria feed off fibre. If you stop eating fibre then those bacteria die off and are replaced by other bacteria that feed on the foods you continue to eat.
@@leemanwrong Yes, corpse eating bacteria.
May I call you Miss Info?
Agree ! They are very missinfo ...
Robert Lustig, MD says fiber is GREAT.
You are taking what he said out of context.
When I was on keto/carnivore I had nothing but the most awful gas and runny diarrhea ever. Not to mention it kicked off my gallbladder issues that prevent normal bowel movements. High fat absolutely clogs the gallbladder and if people stay on keto, they can never get off of it. Ever since I started incorporating more fruits and vegetables I go to the bathroom, no issues. Keto drastically improved my mood but did shorten my fuse without all the sugar to satiate my anger. I doubt most of the people in this comment section have been on keto/carnivore for long enough to actually experience consequences. For those that have, they're just lucky or lying about how disciplined they really are.
I love fibre and fibre loves me
Im 52 and vegetarian since birth , and in tip top gut shape . You tube is full of vids that do not chime with my reality at all and are half full of crap .
Waste product meh ....
It’s basically indigestible by humans as our colon and cecum are so small, we do have a small capacity to ferment fibre to short chain fatty acids but we can also get these from ketones so basically a waste product.
@@leemanwrongthe humans means also the mocrobiome , sir ... So you are simply wrong, because you and also Zoe seems to not to know anything about gut bacteria and what are enhancing them and what not ... And how some fibres are protective for our nervous system after being digested from the gut bacteria
@@jozsiiosif672 No one really knows anything about our microbiome we have only scratched the surface. There have been no decent studies done on fibre the only somewhat half decent study was done by Paul Mason which only showed benefits to not consuming fibre. One thing we do know is fibre is non essential as many people including myself have gone years without consuming it and we show no signs of any detrimental effect.
Why eat fibre when most of it passes straight through unconsumed into the toilet.
@@leemanwrong you are lying ! If you didn't study about microbioma that doesn't mean that anybody knows anything about it !
Zoe is really going downhill she's aged about 20 years in the last 5. No hate just obviously not healthy diet
What is her age now ????????
This is a joke right?!?!?
No joke! Some people do well with minimal fiber and others thrive with more of it. It's nutrition, it's trial and error.
I am Carnivore....
NO FRUIT..NO VEGETABLES......NO FIBRE
3 and half years...
Cows eat fibre..
Humans eat meat..,simple
Just stopped fiber intake 2 Weeks ago. All my bloating and some other more severe but not open to public problems stopped kind of magiacly. Since i know really many people with similar problems. I think they should try it for themselves. The fiber problems were gone after the first week.
I eat zero fiber and it has changed my life! No IBS no gas no bloating no bleeding no diarrhea
Go back to school
What do I eat as I don’t eat animals?
If you don't eat animals then you want to make sure you structure your diet to get your essential nutrients. supplement with vitamin b12. I'm sure there are helpful videos online for vegetarian and vegan type diets.
Why not? Do you not realize just how many living creatures died for your vegan diet? Check out a farm some day.
Start eating eggs, eggs aren't animals
You eat crops so you are killing animals indirectly but not getting any nutritional benefit.
Fibre prevents stasis which is a major cause of bowel cancer and other gastrointestinal disorders. I look at the stuff that you write and think to myself do the opposite to your recommendations and you won't go far wrong. You should have a public health warning tattood to your forehead.
How does fiber prevent stasis? You made a statement without any proof. Instead, it sounds like so much of the unsubstantiated dietary advice that has lead this country to be so overweight and diseased.
Good luck with your piles
The liver needs fiber.
Ok I will bite....
WHY?
No it doesn't.
so no facts, it would not take much research for her to answer her own silly questions. Fiber is not a waste product, it is food for our gut microbes. Soluble fiber gas clinical value to reduce cholesterol. This lady charges money for her REALLY bad advice.
It’s food for some microbes, if you stop eating fibre then those bacteria die off and will be replaced by other bacteria that feed off the food you continue to eat. There’s no demonstrated value in reducing cholesterol.
@@leemanwrong yes, you kill off microbes good for humans and replace them with bad ones that make compounds like TMAO. Many articles on how bad a meat based microbiome are, you might want to actually review peer reviewed scientific papers instead of listening to influencers who are more interested in selling you supplements.
It is also well known that soluble fiber reduce cholesterol. Do you have some evidence. Here is a quick google search: Soluble fiber helps lower cholesterol by:
Binding to cholesterol in the small intestine, preventing it from entering the bloodstream.
Forming a gel-like substance in the intestines, slowing down digestion and trapping cholesterol.
Allowing the trapped cholesterol to be excreted from the body in stool.
Found in foods like oats, barley, legumes, and many fruits and vegetables.
Eating 5 to 10 grams of soluble fiber a day can help lower total and LDL-cholesterol.
Good luck, you have some very bad sources of info that you are following.
Why do you claim we need fiber when there's no such thing as an essential carbohydrate, with or without fiber? You don't need to be eating it. The body only needs essential amino acids and fatty acids. Maybe the problem is that people are clogging up their systems with useless carbs.
why this lady never ever speaks with Dr Will Bulsiewicz....
Doctor B is a flaming VEGAN !
Laughable “doctor” just as Doctor Twiggy!
She is wrong, we have a colon that host bacteria to process these fibers. Asides fibers slow absorption of sugar and reduce glycemic index. I eat tons of fibers and don't get any of the problem she mention, lack of fiber is associated with more risk of colon cancer not more as she argues.
If you don't eat sugar then that's really not a big problem. She isn't wrong go onto any zero carb channel on TH-cam and you will hear testimony after testimony of people who have cut out fiber such as myself and who have experienced nothing but benefits. IBS, gas, bloating and bleeding all gone
I dont buy it , the bloating and gas are because your gut bacteria have been damaged by too much antibiotics. Zero carb is an absurdity ad a diet, it will shorten your life significantly, they are mounting evidence that low carb diet are unhealthy on the long term, humans are mostly starch-ivore
We don't need sugar in the diet though, so take in fiber to slow the absorption of something you don't need? How about just need eat the sugar in the first place?
It isn't the lack of fiber that is associated with colon cancer, it's the inclusion of refined carbohydrates that is.
This idea that you don’t need carbohydrates because they are not ‘essential’ is the biggest confusion in nutrition, confusion between essential and beneficial, eating a diet that zero on one macro nutrient will bring tons of issues on the long term. Excluding carbs is an extreme form of diet that will shorten your life. I said carbohydrates not sugar!
Geoss
I'm sorry but this is a bunch of processed insoluble fiber, to put it frankly. People have known for thousands of years the benefits of, and have been eating, whole grains and fruit and vegetables. With the industrial revolution we began to process grains and make white rice and white flour for instance, which have led to much of our current woes. You need only look at historical documents that show the rich people eating lots of cake and white bread and meat getting gout while the poor people are spared such diseases since they are eating whole grain bread and potatoes and oats and various vegetables. Or look at our present society! However the reverse has happened and now it is the poorest people who are restricted to processed foods and the rich people can buy vegetables and fruits, which are indeed much more expensive than ramen and cheap cereal. This lady is using reasons that may sound logical but she is ingoring some very important aspects of the digestive tract function, which are right there in the surgeon's hypothesis. While fiber does not have any nutritional value it serves to push out all the other stuff. That is very important! Its called physics! That being said you dont need to and shouldnt be eating a bowl of all bran for breakfast and metamucil for a midmorning snack and some prunes for dessert. Thats too much! Just getting fiber as it comes in whole grains and vegetables along with your meat and fish and everything else that is great for humans to eat. And water...don't be telling me fiber is bad and you aren't drinking water.
Fibre is very bad for some people, I drink water, I don’t eat fibre, I don’t consume carbs.
Zoe isn’t ignoring anything if she can help it, she has spent thousands of countless hours reading as many scientific papers as she can on the topic to uncover the truth, which is why she is sharing it.
We are all built different & we have all had different past experiences, & a lot of us have found our health returned by avoiding a lot of the things that you suggest we should be eating, not all of us have that digestive capacity anymore no matter how much we might wish for it.
The microbiome isn't new, if you're skills are supposedly why not to eat carbs and fiber, you should have the sugars and fibers memorized, not 'I just did a speech on this...", kidney beans do soften btw, just not to edibility obviously and has she ever seen copralite, that's ancient human poop and guess what it's full of.....fiber. Sounds like there's a duck in the room.
So what? We have stable isotope analysis which shows our species has predominantly consumed meat for hundreds of thousands of years and very little fibre.
