Is This Saturated Fat Really an Essential Nutrient? 15 Fast Facts About C15

Lol, this inspired me to break gemini. I directly asked gemini how much c15 was in half and half and it insisted that there is absolutely no c15 in half and half. I then did a google search asking how much c15 is in full fat dairy and the AI summary feature (which is also gemini) said that full fat dairy is indeed a source of c15. I then copied that response and pasted it directly into gemini and pointed out that the same model (i.e. itself) produced a different result as a search summary and I asked it to explain the self inconsistency. It never answered and if i repeat the question it consistently states "something went wrong" 😂

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. Edit- I need to add a supplemental note. It is now October, the peak of my usual allergies. Normally, at this point, I am checking the daily weather forecast, hoping for the first hard freeze to kill all the pollen. This year? No seasonal allergies at all. Related to C15? Idk, but this is definitely not normal for me, and nothing else has changed.

Being lactose intolerant doesn't mean you can't have dairy. I can have about 1 cup of milk or yoghurt daily without issues despite being diagnosed with mild lactose intolerance.

@@24bellers20 Yes, you can eat butter (and cheese), but not just any butter. There is much more C15 in milk from cows than feed on grass. 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. If you want adequate C15, 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 much C15.

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]

Send me citation for that hypothesis?

[@sharpgarden8675]

@@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

​@@wyadvd if C15 is found in cheese, it must be in the milk. Anyway, the type of feed obviously affects meat and milk quality. Seaweed actually sounds like one of the better feeding options known to me. Definitely better than corn 😅

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.

[@chazwyman]

The main problem is sterilisation which damaged the fat. Pasturisation does not. SO no need to go raw, or god grassfed. Most milk is grassfed in any event - certainly summer milk.

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.

My grandmother used to tell me that nobody needs to drink milk (in her time it was whole milk) by the time we became teenagers. She used to say that a cow's milk was not intended for humans but for calves and that milk was meant to make the calf grow strong quickly. She speculated that it may contain growth hormones or steroids to help the calf put on weight/muscle fast and be independent as soon as possible. As soon as the calf reached a certain age, the cow would wean the calf off of its milk and onto grass. If the calf need not drink milk anymore, neither do we, after a certain age. She also speculated that the growth hormones and steroids in the milk can't tell the difference between a calf and a cancer tumor in us. Maybe that applies only to raw milk...

[@OldRoadFarm-ck3mj]

Calves must be forced to wean. Many cows won't do this themselves, even at the expense of the calf they are pregnant with. For many cultures dairy was the only reason they survived. Horses, sheep, cattle, goats, water buffalo, camels, yaks, reindeer, all have been utilised for their milk by different cultures, for adults as well as children. If any of what your grandmother believed was true those cultures would have died out.

[@yurinator4411]

@@OldRoadFarm-ck3mj They are forced to wean early by farmers in order to keep the cow economically feasible. It is usually done about 6 to 8 months after birth. Left to nature, calves are naturally weaned by their mothers about 10 months after birth, on the average. The heifers naturally wean after about 9 months and the bulls after about 11 months.

[@OldRoadFarm-ck3mj]

​@@yurinator4411 Often they don't. I've had some very difficult calves that required weaning rings as adults to stop them nursing off their mother, and that was after a span of separation. We only have a small herd on 11 acres. Calves are actually weaned to preserve the condition of the mother so she has the reserves built up to support her next calf. She must have time to build up good quality colostrum and that requires good body condition. If there's a drought calves are weaned even earlier. It's all about the health of the mother because the financial future of the farm rests on her.

Great video. I would like to see some examples of other cheeses (dairy in general) and how little consumption is needed. Pecorino Romano is the only example ever given in videos on C15. I googled cheddar cheese out of curiosity, and it seemed to my novice brain that it also was very high in C15.

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.

Cows feeding regime affecting C15:0 concentrations in milk probably has more to do about the fact that it affects the bacteria in the rumen. Whille the mammary gland can synthesize C15:0 from proprionate, bacterial cell walls are also a source of C15:0. Diets rich in grains like corn can significantly reduce rumens ph, thus affecting the bacterial populations.

Guys, there’s a massive difference between being deficient in key nutrients, supplementing those nutrients, and getting those nutrients through unhealthy sources. Just because under-nourished people and old people benefit from more C15, and supplementing works, doesn’t mean you should start pounding whole-fat dairy. It’s disappointing that Nick doesn’t make these distinctions, and he doesn’t talk about the large body of literature behind dietary recommendations to minimize saturated fat from dairy. I would expect more rounded discourse from a professional researcher, not a keto stan account.
