@@24bellers20 Yes, you can eat butter (and cheese), but not just any butter. The C15 is not made by the cows any more than we can make it. The grass makes the C15, and being a fatty acid, the cow absorbs it, then releases some into it's milk. The problem is more than just that "they" told us to stop drinking full fat milk. The other side is that, to save money, the dairy industry stopped letting cows graze on grass. You need to eat butter (or cheese) from pasture raised animals. You can still find it, if you buy Irish butter, or butter from New Zealand, and sometimes Germany, but I have not seen any pasture raised butter of US origin at all. Do not, by the way, confuse "organic" milk with "pasture raised" milk. Organic only means that the feed was raised organically. A cow could be fed "organically raised corn", and it would be organic, but it would not contain any C15.

Serious question. With the total nonsense around cows promoting global climate change has come an effort to reduce their methane output from rumination .

Interesting, here in Australia, one of our milk brands has a cold pressed milk, treats the milk, but doesn't cause the heat damage pasteurisation causes. Would love to know the effects on C15.
It doesn't look like it, given how SFAs act in "vegetable oils": _During the heating process the polyunsaturated fatty acid (PUFA) content of vegetable oils decreases while that of saturated fatty acids (SFAs) usually increases._ => "Effects of Repeated Heating on Fatty Acid Composition" NIH PMC8774349.

I have two anecdotes. I am taking C15, and a lady friend in taking C15. I typically eat full fat Irish (pasture raised) butter, but not very much. She is lactose intolerant, and eats no dairy at all. I am very healthy. She has many medical issues, including type 2 diabetes. I noticed no change, but when I looked carefully, my liver enzyme tests (ALT, AST, alkaline phosphatase) all dropped to where they were 7 years ago. Her changes could be a coincidence, so don't confuse anecdotes with data, but here goes: Her health in general improved. Her liver enzymes dropped back into normal range. Her A1C dropped from diabetes range to pre-diabetes range. Her doctor has had to reduce her daily insulin intake 5 times, and it is now about 20% of what she used to take daily. Remember, these are just anecdotes from some random guy on the internet, and don't prove anything. Trust the random studies, not random people.
Google AI just now says yes to C15 but is concerned about other saturated fats that may be unhealthy. I didn't make this up! Yes, C15 (pentadecanoic acid) is found in full-fat milk. It's one of the odd-chain saturated fatty acids (OCFAs) present in dairy products. C15 is particularly interesting because it's been linked to potential health benefits, such as improving cellular health. However, it's important to note that while full-fat milk contains C15, it also contains other saturated fats that might have less favorable health implications. If you're interested in learning more about C15 and its potential benefits, you might want to consult with a healthcare professional or nutritionist.
You got it… bye bye Fat free chocolate milk, pizza bagels and 15 minutes of physical activity… hello full fair dairy, adequate protein and a proper recess (with dodgeball please 🙏🏻)
Nick, please discuss the idea that the “unnatural” high levels of stored omega 6 in modern man`s viceral fat can be protected from oxidation by C15. If modern man demand quite a lot of certain antioxidants to prevent the stored PUFA from going rancid, will this take away limited antioxidant resources from the cell membranes and intracell membranes (as around miticondrias)? Limited intake of omega 3 will then be less critical when protected by C15 because the cell membranes themselves will last longer (less demand of omega 3). Thank you for interesting presentations. Best regards Mr. Helge
@@nicknorwitzPhD Dear Nick, It is my own hypothesis based on the information that C15 integrated in the membranes makes them "stronger"/"stiffer"/"more resistant". It is established knowledge that modern man often got 3 times more stored omega 6 than the palioman. It is also established that half life of stored omega 6 is 2 years. When it takes about 4 years to get rid of excess omega 6, longer than mouse life span. I do belive mouse experiments are of less value. It is reasonable to belive that PUFAS stored at 37C for 4 years will go rancid without the right amount of antioxidants. Best regards Mr Helge
Hi Nick, I am following you very strictly because I am very, very ill. My immune system is really upside down, and I have many different symptoms at the same time that make me suffer a lot. Crohn's disease and also the connected rheumatic implications have really debilitated my body in the last 20 years. 2 months ago, I have taken the road of the Lion diet but I have encountered many difficulties. At the moment, many problems are solved and my body is healing in some way because I feel better and I have less pain in the joints. I would like to ask you a question as follows: Do you suggest I integrate dairy and eggs? Because I struggle on only cow meat and also I have lost a lot of weight and I am lean. Of course, I am doing my best to eat as much as possible but with only meat, it is difficult. I really like cheese etc., so it is not a problem. Through your experience with Crohn's disease, do you find that having also something else than meat is good for our healing? Please reply, it is very important for me and also I believe in your competence.
I'm sorry for your struggles, and I'm sorry I can't provide you personal medical advice. That wouldn't be appropriate. But I'm glad you're feeling better. I think the best course is to be careful and observant about what triggers your symptoms. Nobody can tell you better than that. When I've tried carnivore, I include fish and lamb, not just beef. I also included eggs and A2 dairy. But that's me.

As for the CBD connection, humans have evolved eating animals and drinking milk. I've always thought it was implausible that we would have evolved with CBD receptors. That makes no sense at all. Now that this connection to C15 has appeared, it make a ton of sense. It makes perfect sense that humans would have evolved with C15 receptors, receptors that also happen to be able to connect to CBD.
I quit dairy years ago due to allergies. I can have cheese or organic A2 grass fed whole milk yogurt once or twice a week with no problem. But you will have to pry ghee out of my old, cold, dead hands.
And the same source, Google AI on C15 and butter. I had just also asked about cheddar cheese. "C15 fatty acids in butter Similarly to Cheddar cheese, C15 fatty acids, specifically pentadecanoic acid (C15:0), are also present in butter. They are a part of the milk fat composition, contributing to the overall fatty acid profile of the butter. Key points about C15 fatty acids in butter: * Presence: They are naturally occurring components of butter, derived from the milk fat. * Type: Pentadecanoic acid (C15:0) is the primary C15 fatty acid found in butter. * Amount: The exact amount can vary depending on factors like the type of milk used and processing methods. * Role: They contribute to the overall flavor, texture, and nutritional profile of butter. Would you like to know more about C15 fatty acids or their role in butter?" So, maybe Google has been listening to Nick?
No... you can still feel hunger on keto. But ketones ca reduce hunger and a ketogenic diet can reduce hunger. But it would be pretty awful if hunger drive went away entirely without carbs.
If C15 is actually essential then shouldn't we see large numbers of older vegans with deficiencies and specific symptoms or diseases associated with the deficiency?
Any of the older vegans I’ve seen do not look healthy at all. And something like 85% of vegans give it up within the first 3 years. Their level of C15 may depend on how much they had stored in their body before they chose the vegan diet.
@@zenamatthews9380 Then cite the studies and statistics that irrefutably show that vegans and vegetarians don't live as long as omnivores and explain what specific causes of death are responsible for the lower longevity.
I'm a big fan, Nick, but I heard the word "association" and awful lot in this video, and we all know the main stream medical community uses that word a lot in trying to tear down keto and carnivore diets.
Epidemiology isn’t worthless… it just needs to be situated in the appropriate context. I don’t think I apply double standards. And don’t let poor interpretations of data poison you to said form of data or listening to reason that uses overlapping terminology. By way of goofy analogy, if someone said “There’s an association between eating eggs and good eye health,” you might be curious and generate hypotheses based on this association that you would frame with other data and biological plausibility, versus if someone said “there’s an association between eggs and interactions with aliens” … well… less plausibility
Another brilliant and highly educational video. Keep them coming please (despite 4th year med school!). My partner, a Pediatrician, will love the whole milk in school recommendation.
Dairy isn't just fat, it's also hormones, eh? After all, it's "breastmilk", and there's a reason why mammals evolved to be weaned off at some point after birth.
Right . Please Drink Super Healthy Coffee instead of unhealthy hormones in raw fresh whole grass fed organic milk , which humans have been drinking for millions of years . How people are br a i n wash ed these days is just pure madness !
The Maasai people of Africa thrive on largely blood and milk and butcher an animal only on special occasions. Their cattle are very valuable to them. Those still living on the traditional diet have none of the so called diseases of civilization. Also being on the farm I’ve seen barn cats lining up to get a fresh warm squirt of milk straight from the cows teat at milking time. So I’m not at all convinced about this idea that’s been so heavily promoted.
Great video. I want to add that In Spain we have MANCHEGO CHEESE. Manchego is a very similar cheese to Pecorino as it is made from sheep’s milk, aged for a certain amount of time, and has a salty, strong flavor and a crumble texture if you choose the aged version. The only difference between Pecorino and Manchego is the region in which they are made and when you eat them it is very difficult to notice any difference.
@@nicknorwitzPhD I guess the obvious needed to be stated. I do have a little tolerance but yeah milk is out. Goat and sheep, I'll have to try, if my tongue gets sore then problem. Of course I do this at my own risk, but I know the signs. This has been an issue most of my life. Fun thing, when I did vegetarian my tongue got sore and when I searched for where the milk came from I found it in my burger patties and so called vegetarian cheese. Vegetarian didn't work for me.
The fact that c15 appears the most in grassfed animals is the reason pecorino and probably goat cheese are the richest. Both animals are obligate grass fed while cows are often fed grains should their welfare not be good. Sardinia had very few cows traditionally therefore sheep and goat milk would be the mpst present.
You mentioned the importance of C15 fatty acids for cell membrane integrity. How about doing a presentation on the importance of cholesterol in the structure and FUNCTION of human cell membranes (including neuronal tissues) and why it might NOT be a good idea to lower blood and brain cholesterol.
I heard a recent talk on C15 and this video is very timely! The veterinarian that discovered the role of c15 mentioned dairy animals that live at higher altitudes produce more c15. So, the best full fat would come from high altitude dairy. Yak milk or reindeer milk??? Not only do these animals typically live at a higher altitude but it their milk has an overall higher fat percentage.
Do you think the C15 longevity study could also be impacted by the fraud/error rates of blue zones uncovered by Saul Newman's recent work? Just one more possible reason to take that study lightly. Great video, Nick!
As I mentioned, I think there are issues in the Human Longevity Lit. I still thought it was a "fun fact," but I wouldn't make strong claims. Also, the different was only trending and definitely potential for confounders. But taken in the context of the animal model (incl Dolphin) lit... it's interesting
How can C15 be an essential nutrient. So many populations didn’t consume any forms of dairy? Surely we can’t be deficient in something that large groups of humans didn’t consume?
Excellent videos Nick!! Keep up the good work! I've been involved in food safety (but not dietary value) all my professional life. When I started to discover the absolute disaster hidden in the dietary recommendations, I basically lost my confidence in science in general. We have a very long road ahead to crawl out of this black hole called "dietary recommendations".
Your video made my day 😂 but on a serious note, I stopped eating full fat dairy because (supposedly) antibiotics pass through to humans through dairy fat. So we need to use grass-fed antibiotics-free whole milk to get "safe" C-15.0 -- yes?
Thank you for the info, this is an interesting topic. A peeve, though: why not mention the existence of plant sources of C15? They are abundant: several vegetable oils and green veggies, for example. This may create the impression that one must consume dairy products, or else. Some other comments seem to indicate that several viewers indeed got this impression.
Thanks for the feedback. Can you send me references on the best plant sources of C15? Specifically looking for sources with comparable amounts to dairy or high C15 fish.
I followed keto for 6 months and developed super high LDL and cholesterol. I had no energy and put on 10lbs. I felt terrible. I really wanted it to work! Feeling so much better now. I’m APoE4. No Sat fat for me.
Ok I had to watch this again. I'll check out the other video. I am curious on if c15 would be helpful to a diabetic working on putting their disease into remission while on a keto style diet. When I first heard about this during an interview with the biologist I was skeptical when she plugged a C15 pill. Watched the recommended video. I am still skeptical. I'd like to try some sheep cheese though.

I'm drinking 1.5l of whole fat milk a day for my bulk. My cholesterol levels were quite high. It's been a month now, do you think they're gonna be much worse? We'll see soon hah.
The average American should have plenty of C15. Yes dairy is good 1ounce of heavy cream is 105 mg. A six ounce steak has 99 MG. 3 oz of Pepperoni has 108 Mg so any way very easy for most people to hit over 200 mg if they include animal products in their diet. One double patty cheese burger gets your over 200 Mg. If you are Carnivore you are getting a ton of it. Vegans may want to supplement, or if somehow you are following high carp low fat with lean proteins they may also need to supplement.
Excellent. I was drinking low fat milk the past 15 years and switched to reduced fat about a month ago. I knew nothing about C15, but I am glad I made the right choice.
Isn’t whole milk a perfect combo of sugars and fats ideal for spiking insulin and maintaining hyperinsulinemia if consumed regularly? Perhaps butter is a better alternative?
Safe to say Whole Raw Milk vs Whole Ultra Pasteurized is better? Or because fats are still in pasteurized milk there's not much of difference? Tho benefits of enzymes n probiotics plus fats are in better in raw. Aren't catfish bottom feeders and high in histamine, so a con?
I’m fond of sheep milk feta and of Pecorino. I make ghee from grass-fed butter and it’s my usual cooking fat. Long-time type 1 diabetic so I probably need all the help that I can get…
A major caveat of all this is that lactose intolerance present in significant numbers that indirectly puts them at higher risks of C-15 deficiency due to restriction in consuming C-15 rich dairy products do not seem to demonstrate a higher risk of all metabolic diseases.
I'm hearing a lot of "appears to" and "associates with" in this video. I am not convinced. I am also sure the dairy industry would love to propagate this information.
I get colitis flare ups with dairy, no matter if it is high fat or low. Now I know that this video is not about how dairy affects chrons or colitis but my question is since you're someone who has suffered from Crohn's correct? Are you able to consume dairy with your condition?
I get that not all saturated fats are bad. But could the health benefit of ingesting foods like dairy products with high C-15 be offset by the deleterious effects of high amounts of other saturated fats in these foods?
Growing up my parents were told that skim milk was better than whole milk. When I went on Rick's Heart Attack Diet I demanded whole milk which was the same price. Drank it from age 15 to age 20. Since then I went to full fat cheese, sour cream and yogurt. I eat dairy daily. Could that be a reason I look and feel younger than all my my equal age friends?
BS. According to NIH gov't website, hard cheeses have 4.5mg of C15 per gram of FAT. And since pecorino cheese has 32% fat, half an ounce of that cheese gives you only about 5 times 4.5mg which is 22.5 mg of C15
That's BS. You don't get 200mg C15 from half an ounce of Pecorino cheese. You need 3 TIMES as much since there's 1.5% C15 in the FAT of the cheese, not per the whole cheese. And there's 32% of fat in the cheese
Not in any appreciable amounts that I know of. That said, the supplement line - with which I have no present affiliation - is a vegan product. They produce C15 from extending C14
so enjoy listening to your lectures Nick! Keep up the good work and all the puns!! Cheers from Ontario, Canada

Awesome review and breakdown Nick. And Yes, bring back full fat dairy to school lunches!!!!!!
You got it… bye bye Fat free chocolate milk, pizza bagels and 15 minutes of physical activity… hello full fair dairy, adequate protein and a proper recess (with dodgeball please 🙏🏻)
Ever wonder why dairy farmers live longer?????
Nick, please discuss the idea that the “unnatural” high levels of stored omega 6 in modern man`s viceral fat can be protected from oxidation by C15.
If modern man demand quite a lot of certain antioxidants to prevent the stored PUFA from going rancid, will this take away limited antioxidant resources from the cell membranes and intracell membranes (as around miticondrias)?
Limited intake of omega 3 will then be less critical when protected by C15 because the cell membranes themselves will last longer (less demand of omega 3).
Thank you for interesting presentations.
Best regards Mr. Helge
Send me citation for that hypothesis?
@@nicknorwitzPhD Dear Nick, It is my own hypothesis based on the information that C15 integrated in the membranes makes them "stronger"/"stiffer"/"more resistant". It is established knowledge that modern man often got 3 times more stored omega 6 than the palioman. It is also established that half life of stored omega 6 is 2 years. When it takes about 4 years to get rid of excess omega 6, longer than mouse life span. I do belive mouse experiments are of less value. It is reasonable to belive that PUFAS stored at 37C for 4 years will go rancid without the right amount of antioxidants.
Best regards
Mr Helge
Nick's presentation has been easier to understand for lay person like me. In other words he is less 'nerdy' now. Thanks Nick!
I'm trying to provide content at multiple levels of depth to make my overall intellectual ecosystem more accessible.
Hi Nick,
I am following you very strictly because I am very, very ill. My immune system is really upside down, and I have many different symptoms at the same time that make me suffer a lot. Crohn's disease and also the connected rheumatic implications have really debilitated my body in the last 20 years.
2 months ago, I have taken the road of the Lion diet but I have encountered many difficulties.
At the moment, many problems are solved and my body is healing in some way because I feel better and I have less pain in the joints.
I would like to ask you a question as follows:
Do you suggest I integrate dairy and eggs?
Because I struggle on only cow meat and also I have lost a lot of weight and I am lean. Of course, I am doing my best to eat as much as possible but with only meat, it is difficult.
I really like cheese etc., so it is not a problem.
Through your experience with Crohn's disease, do you find that having also something else than meat is good for our healing?
Please reply, it is very important for me and also I believe in your competence.
Try natto in flavoured natural soup. It is the best value for c15.
I'm sorry for your struggles, and I'm sorry I can't provide you personal medical advice. That wouldn't be appropriate. But I'm glad you're feeling better. I think the best course is to be careful and observant about what triggers your symptoms. Nobody can tell you better than that. When I've tried carnivore, I include fish and lamb, not just beef. I also included eggs and A2 dairy. But that's me.
@@PeterDMayr Soy is not going to help and natto causes gastric distress for some people.
Thank you for your advices. I am not seeking a medical advice but I am looking to understand what path did you followed. Now what are you doing for your crohn disease? Are you on medication or what "kind" of diet are you following? Thanks @@nicknorwitzPhD
@@OldRoadFarm-ck3mj Some people. I hope it doesn't for you. I'm trying to ascertain if natto has c15. Maybe? Research/review on: Update on food sources and biological activity of odd-chain, branched and cyclic fatty acids -- A review
I'M NOT THAT SHELLFISH!!! OMG LOLOL!!!
Thank you for this video!!!!
Could you do a deep dive video on the randle cycle, especially regarding how fast the switch is between fatty acid and glucose utilization when the diet is mostly protein and fats, plus a little bit of glucose from plants(under 25-50 total carbs)?
Glad you liked the pun.
As for the CBD connection, humans have evolved eating animals and drinking milk. I've always thought it was implausible that we would have evolved with CBD receptors. That makes no sense at all. Now that this connection to C15 has appeared, it make a ton of sense. It makes perfect sense that humans would have evolved with C15 receptors, receptors that also happen to be able to connect to CBD.
I am lactase persistent, I drink grassfed Cream top whole milk. It is small batch VAT pasteurized dairy.
I second the question about the effect of pasteurization, whether it's low temperature, high temperature, or ultra high temperature? Thanks
Ahhhh… so glad you’re talking about C15! Been reading about it recently! 👍
Glad you enjoyed
Interesting, useful and crisp. Great video
Many thanks!
I quit dairy years ago due to allergies. I can have cheese or organic A2 grass fed whole milk yogurt once or twice a week with no problem.
But you will have to pry ghee out of my old, cold, dead hands.
Thanks!
Thank you very much!! I wonder what I’ll spend this on?
@@nicknorwitzPhD
Pecorino cheese???
According to Neal Barnard there is no essential saturated fat. Wondering when he will admit his error.
He also said ketones are poison to the body… really 😅
@@nicknorwitzPhDSome people never retreat; they reload
Thanks for clarifying about omegs-3. Omega-3 is the balm for my dry eye syndrome.
And the same source, Google AI on C15 and butter. I had just also asked about cheddar cheese.
"C15 fatty acids in butter
Similarly to Cheddar cheese, C15 fatty acids, specifically pentadecanoic acid (C15:0), are also present in butter. They are a part of the milk fat composition, contributing to the overall fatty acid profile of the butter.
Key points about C15 fatty acids in butter:
* Presence: They are naturally occurring components of butter, derived from the milk fat.
* Type: Pentadecanoic acid (C15:0) is the primary C15 fatty acid found in butter.
* Amount: The exact amount can vary depending on factors like the type of milk used and processing methods.
* Role: They contribute to the overall flavor, texture, and nutritional profile of butter.
Would you like to know more about C15 fatty acids or their role in butter?"
So, maybe Google has been listening to Nick?
Are you concerned about the link between dairy consumption and parkinson's disease?
Ok so my question... is the heavy cream that I use in my coffee a source of C15?
Please tell me ice cream has C15? If so then I’m good… 😅
Technically… 👀
Another excellent report. Deserves another $Thanks$ above.
Thank you 🙏🏻
New to channel, what causes high cholesterol in your opinion?
I have a whole playlist on cholesterol and lipids you can check out if you’re so inclined :):)
adding GOMAD to my carnivore way of life. Got it.
More full fat dairy for me and pecorino cheese! Yummy 😋
hey Nick is it true that on keto one never feels hungry? if that's the case, ketosis could make weight loss easy.
No... you can still feel hunger on keto. But ketones ca reduce hunger and a ketogenic diet can reduce hunger. But it would be pretty awful if hunger drive went away entirely without carbs.
I find keto, and even more, Carnivore reduces my food cravings and makes it easier to avoid binge eating.
If C15 is actually essential then shouldn't we see large numbers of older vegans with deficiencies and specific symptoms or diseases associated with the deficiency?
Any of the older vegans I’ve seen do not look healthy at all.
And something like 85% of vegans give it up within the first 3 years.
Their level of C15 may depend on how much they had stored in their body before they chose the vegan diet.
I mean... We do. In fact, very few vegans become old vegans. I just can't prove to you that it's because of C15 specifically.
@@zenamatthews9380 Then cite the studies and statistics that irrefutably show that vegans and vegetarians don't live as long as omnivores and explain what specific causes of death are responsible for the lower longevity.
6:40
@@ImaJunkyoBell I mean they quit being vegan due to bad health outcomes from their diet.
I love heavy creams, preferrably unpasturized. Specially half-frozen. Best replacement for ice cream.
Sounds great
I'm a big fan, Nick, but I heard the word "association" and awful lot in this video, and we all know the main stream medical community uses that word a lot in trying to tear down keto and carnivore diets.
Epidemiology isn’t worthless… it just needs to be situated in the appropriate context. I don’t think I apply double standards. And don’t let poor interpretations of data poison you to said form of data or listening to reason that uses overlapping terminology. By way of goofy analogy, if someone said “There’s an association between eating eggs and good eye health,” you might be curious and generate hypotheses based on this association that you would frame with other data and biological plausibility, versus if someone said “there’s an association between eggs and interactions with aliens” … well… less plausibility
Another brilliant and highly educational video. Keep them coming please (despite 4th year med school!). My partner, a Pediatrician, will love the whole milk in school recommendation.
Fantastic! And GO your partner!!
Dairy isn't just fat, it's also hormones, eh? After all, it's "breastmilk", and there's a reason why mammals evolved to be weaned off at some point after birth.
Whole food is never just macronutrients. Each is a complex ecosystem.
Right .
Please Drink Super Healthy Coffee instead of unhealthy hormones in raw fresh whole grass fed organic milk , which humans have been drinking for millions of years .
How people are br a i n wash ed these days is just pure madness !
The Maasai people of Africa thrive on largely blood and milk and butcher an animal only on special occasions. Their cattle are very valuable to them. Those still living on the traditional diet have none of the so called diseases of civilization.
Also being on the farm I’ve seen barn cats lining up to get a fresh warm squirt of milk straight from the cows teat at milking time. So I’m not at all convinced about this idea that’s been so heavily promoted.
I’m glad I found your channel. So informative! I just recently switched to a grass fed greek yogurt. Great timing!
Indeed! Welcome!
Great video. I want to add that In Spain we have MANCHEGO CHEESE. Manchego is a very similar cheese to Pecorino as it is made from sheep’s milk, aged for a certain amount of time, and has a salty, strong flavor and a crumble texture if you choose the aged version. The only difference between Pecorino and Manchego is the region in which they are made and when you eat them it is very difficult to notice any difference.
pecorino cheese, made from sheep milk, This I may not be allergic to.
If you're allergic... don't eat it.
@@nicknorwitzPhD I guess the obvious needed to be stated. I do have a little tolerance but yeah milk is out. Goat and sheep, I'll have to try, if my tongue gets sore then problem. Of course I do this at my own risk, but I know the signs. This has been an issue most of my life. Fun thing, when I did vegetarian my tongue got sore and when I searched for where the milk came from I found it in my burger patties and so called vegetarian cheese. Vegetarian didn't work for me.
The fact that c15 appears the most in grassfed animals is the reason pecorino and probably goat cheese are the richest. Both animals are obligate grass fed while cows are often fed grains should their welfare not be good. Sardinia had very few cows traditionally therefore sheep and goat milk would be the mpst present.
You mentioned the importance of C15 fatty acids for cell membrane integrity. How about doing a presentation on the importance of cholesterol in the structure and FUNCTION of human cell membranes (including neuronal tissues) and why it might NOT be a good idea to lower blood and brain cholesterol.
Great information presented with professionalism and humour. Love your videos.
Glad you like them!
Great walkthrough on this topic! By the way, what's your opinion on coffee?
Black Coffee (no sugar)☕ & Butter 🧈 good
As an medical trainee, I'm a fan.
@@nicknorwitzPhD have you tried butter in your coffee yet? Of course grass fed unsalted
I heard a recent talk on C15 and this video is very timely! The veterinarian that discovered the role of c15 mentioned dairy animals that live at higher altitudes produce more c15. So, the best full fat would come from high altitude dairy. Yak milk or reindeer milk??? Not only do these animals typically live at a higher altitude but it their milk has an overall higher fat percentage.
So are vagoons C15 deficient (as they are with many other essential nutrients)?
It's a logical extension of hypotheses around C15.
Do you think the C15 longevity study could also be impacted by the fraud/error rates of blue zones uncovered by Saul Newman's recent work? Just one more possible reason to take that study lightly. Great video, Nick!
As I mentioned, I think there are issues in the Human Longevity Lit. I still thought it was a "fun fact," but I wouldn't make strong claims. Also, the different was only trending and definitely potential for confounders. But taken in the context of the animal model (incl Dolphin) lit... it's interesting
Dose diary causes Ms?did you heard that?I'd love to know your opinion
THere's an association in particular between A1 dairy and autoimmune diseases. This may have to do with how A1, but not A2, is processed into BCM7
What about heavy cream? That is nothing but dairy fat. Trying to look up whether it's a good source of it but am not finding anything.
How can C15 be an essential nutrient. So many populations didn’t consume any forms of dairy? Surely we can’t be deficient in something that large groups of humans didn’t consume?
Excellent videos Nick!! Keep up the good work! I've been involved in food safety (but not dietary value) all my professional life. When I started to discover the absolute disaster hidden in the dietary recommendations, I basically lost my confidence in science in general. We have a very long road ahead to crawl out of this black hole called "dietary recommendations".
We love 36% cream, butter and cheese in this low carb house!
Sounds great!
I think I upset some vegans on a Fatty 15 FB ad.
I said, "wow I just took a big dose of fatty 15 via a ribeye and glass of milk and I feel amazing"
Right now there are certain pockets of the vegan world that aren't happy with me because of the Egg thing.
Your video made my day 😂 but on a serious note, I stopped eating full fat dairy because (supposedly) antibiotics pass through to humans through dairy fat. So we need to use grass-fed antibiotics-free whole milk to get "safe" C-15.0 -- yes?
Thank you for the info, this is an interesting topic. A peeve, though: why not mention the existence of plant sources of C15? They are abundant: several vegetable oils and green veggies, for example. This may create the impression that one must consume dairy products, or else. Some other comments seem to indicate that several viewers indeed got this impression.
What is the level of bioavailability from plant sources?
Thanks for the feedback. Can you send me references on the best plant sources of C15? Specifically looking for sources with comparable amounts to dairy or high C15 fish.
I make everything from raw dairy and keep it raw when I make kefir, yogurt and cheese. Good stuff!❤❤❤
I followed keto for 6 months and developed super high LDL and cholesterol. I had no energy and put on 10lbs. I felt terrible. I really wanted it to work! Feeling so much better now. I’m APoE4. No Sat fat for me.
I eat full fat plain greek yogurt and cottage cheese. Is c15 present in these two?
Ok I had to watch this again. I'll check out the other video. I am curious on if c15 would be helpful to a diabetic working on putting their disease into remission while on a keto style diet. When I first heard about this during an interview with the biologist I was skeptical when she plugged a C15 pill. Watched the recommended video. I am still skeptical. I'd like to try some sheep cheese though.
I'm drinking 1.5l of whole fat milk a day for my bulk. My cholesterol levels were quite high. It's been a month now, do you think they're gonna be much worse? We'll see soon hah.
The average American should have plenty of C15. Yes dairy is good 1ounce of heavy cream is 105 mg. A six ounce steak has 99 MG. 3 oz of Pepperoni has 108 Mg so any way very easy for most people to hit over 200 mg if they include animal products in their diet. One double patty cheese burger gets your over 200 Mg. If you are Carnivore you are getting a ton of it. Vegans may want to supplement, or if somehow you are following high carp low fat with lean proteins they may also need to supplement.
Keep

Cultured
Raw
A2 Dairy
Grassfed preferred but not hopeless cause w/o it!
I eat Greek high fat yogurt, Keifer, high fat unflavored whipping cream. I have no negative effects..
Lovely
I do enjoy these as well, it it appears to cause weight loss stalls or have me gain weight.
Excellent. I was drinking low fat milk the past 15 years and switched to reduced fat about a month ago. I knew nothing about C15, but I am glad I made the right choice.
Isn’t whole milk a perfect combo of sugars and fats ideal for spiking insulin and maintaining hyperinsulinemia if consumed regularly? Perhaps butter is a better alternative?
Safe to say Whole Raw Milk vs Whole Ultra Pasteurized is better? Or because fats are still in pasteurized milk there's not much of difference? Tho benefits of enzymes n probiotics plus fats are in better in raw.
Aren't catfish bottom feeders and high in histamine, so a con?
I’m fond of sheep milk feta and of Pecorino. I make ghee from grass-fed butter and it’s my usual cooking fat. Long-time type 1 diabetic so I probably need all the help that I can get…
A major caveat of all this is that lactose intolerance present in significant numbers that indirectly puts them at higher risks of C-15 deficiency due to restriction in consuming C-15 rich dairy products do not seem to demonstrate a higher risk of all metabolic diseases.
I'm hearing a lot of "appears to" and "associates with" in this video. I am not convinced. I am also sure the dairy industry would love to propagate this information.
Milk today is inflammatory, unlike the milk of old. Some drink goats milk, as it is A2. Whole foods of yesteryear were so much better all around.
I get colitis flare ups with dairy, no matter if it is high fat or low. Now I know that this video is not about how dairy affects chrons or colitis but my question is since you're someone who has suffered from Crohn's correct? Are you able to consume dairy with your condition?
Great video Nick, to the point, good coverage of the studies and points! Much appreciated! :)
So people ate less whole fat dairy, but what about cheese? It seems like pizza is still kinda popular. Did the total amount of dairy fat decrease?
If there is C-15 in grass fed cows-milk, is there sufficient C-15 in grass fed cow-steaks?
I get that not all saturated fats are bad. But could the health benefit of ingesting foods like dairy products with high C-15 be offset by the deleterious effects of high amounts of other saturated fats in these foods?
Growing up my parents were told that skim milk was better than whole milk. When I went on Rick's Heart Attack Diet I demanded whole milk which was the same price. Drank it from age 15 to age 20. Since then I went to full fat cheese, sour cream and yogurt. I eat dairy daily. Could that be a reason I look and feel younger than all my my equal age friends?
Good information considering I mostly live on what my house cows produce.
🤯
@@nicknorwitzPhD 😂 Bear in mind that also includes a fat calf to fill the freezer once it's 18 months to 2 and a half years old.
GOOD INFORMATION, PLEASE MAKE SMALLER VIDEO AND SUMMARIZED DETAIL.
Great lecture Doc. I learned some stuff here.
Glad it was helpful!
BS. According to NIH gov't website, hard cheeses have 4.5mg of C15 per gram of FAT. And since pecorino cheese has 32% fat, half an ounce of that cheese gives you only about 5 times 4.5mg which is 22.5 mg of C15
That's BS. You don't get 200mg C15 from half an ounce of Pecorino cheese. You need 3 TIMES as much since there's 1.5% C15 in the FAT of the cheese, not per the whole cheese. And there's 32% of fat in the cheese
How does pasteurization affect this?
are there any plant sources of C15? if so, what are the top plant sources?
Not in any appreciable amounts that I know of. That said, the supplement line - with which I have no present affiliation - is a vegan product. They produce C15 from extending C14
