@@nicknorwitzPhD Have you considered eating invasive species of fish like asian carp? Since they are top feeders eating alage / plankton they are exceedingly low in heavy metals. And since they eat so much algae they are high in omega 3, almost as much as salmon, not to mention eating them help to protect our local ecosystem.
Kudos for the caveats. Most nutritional RUclipsrs fail on that regard and lean toward an obvious agenda. Keep that up. Also, I like the recipe tips since it facilitates implementation. I'm starting to really enjoy your vids. I love the biochem and physiology aspects as well. Refreshing all around.
Thanks. Helpful, as always. Many people eat the SMASH fish - salmon, mackerel, anchovies, sardines, and herring because they are all good sources of DHA and EPA. For example, 100 grams of sockeye salmon has 1.2 grams of omega 3. Cod livers are an even richer source, and so is cod liver oil. I buy canned cod livers from Iceland. The livers are packed in cod liver oil. Each can contains around 5 grams of DHA and 5 grams of EPA, about half from the livers and half from the oil. I make a salad with cilantro, tomato, cucumber, garlic, green onion, capers, sesame seed, pumpkin seed, sunflower seed, Italian Herbs, and balsamic vinegar. Then I mix in the liver and the cod liver oil. Note that the livers have a much milder taste than the oil, and you can add curry powder to mask the fishy taste of the oil.
Please try to organise an interview with Professor Michael A Crawford (age 90-something) of Imperial College London. He’s spent the best part of his eminent life trying to flag these important benefits up…and to those in positions of influence / power…and all too often ignored.

I have leaned toward healthy fish daily is “probably” better for me in all cause mortality even while taking Eliquis. I loved this presentation. Thanks
I live in a small fishing village. Fishermen have their children sell fresh fish in the morning after the men have been fishing at night. I eat fish several times a week, and when I do it can be the main food source I eat during the day. We buy yellow fin tuna in a nearby town, and it makes up roughly 25% of the fish I eat. I eat a variety of tropical fish, and I eat about two crabs on average a week and occasionally shrimp. There is no heavy industry nearby, so I'm not worried about heavy metals so much. It's good to hear that the yellow fin tuna might be protective against mercury.
Mackerel and Sardines both eat algae and as oily fish are high in omega 3. Tuna is more likely to have higher levels of heavy metal since they eat fish and tend to concentrate the metals in their tissues. This why its good to limit shark and tuna; being higher up the food chain.
What you say is very valid. For quite a long time humans were living off the sea and we almost all live near open water. Fish are not plants and re available all year long. Simple stuff. You do present the actual evidence quite well.

@@kronos77 You mean ;they say its olive but substitute seed oil? Yes I have heard of that, but do not regard it as a serious problem in the UK where food standards tend to be a bit higher than in the USA. IN any event I tend to give the oil to the dog. She loves it.
@@chazwyman Not what I meant at all. Oil exchange is the process by which oil from outside...the olive oil...seeps into the fish amd pushes out the omega 3 containing fish oil. You end up with some of the omega 3s in the can, not the fish. This is also how olive oil bathing worked in the ancient world. The olive oil would push the dirt out of the pores and the caked oil on the body's surface was then scraped away. To your point though, fraud is rampant in the olive oil business. There is said to be more olive oil sold than is produced. I wouldnt worry if you are getting a good quality oil...before I went Carnivore, I used Barani here in the USA...but the fraud is likely when you see olive oil as an j gredient i canned or packaged foods.
Fish absorb mercury and other heavy metals from the water they swim in, and the amount of mercury in a fish's body increases over time as it consumes other fish. This process is called biomagnification, and it means that larger, longer-lived fish like tuna tend to accumulate more mercury in their bodies than smaller, shorter-lived fish like sardines. This is why I mostly eat sardines. I do however eat salmon when I am certain that is wild caught and not farm raised. Farm raised fish are fed corn and grain products. In the wild they get their omega-3s from eating algae or eating other fish that eat algae.
I'm vegan and a senior. Some of my friends/family are passing, and I'm still hiking and snorkeling. You don't have to eat ANY animals to be healthy. Jeannine
I love fish, but all the lead/heavy metal stuff greatly worries me. I've read about far more than one case of someone who was inexplicably ill until they stopped eating fish multiple times per week and in the end it turned out to be some sort of metal poisoning.
@@Myrslokstok heavy metal makes you more aggressive and less inclined to eat fish and chips...I believe it's the best and cadence of the drums that incline many listeners to resort to aggression.
Ya... if you're going to eat fish everyday, I wouldn't make it tuna. I'm a big sardine fan! Also, catfish 'nuggets' (cutoffs) at Star ar $4/lbs and fry up great! coat in egg wash and whey and it kinda tastes like 'fish&chips'
The only fish I like to eat is canned tuna haha! But I do choose skipjack tuna which should be lower mercury, at least it's better than no fish, I really don't like the taste of most fishes
Nick, love your informative videos! Fish - I am highly allergic. Scanned comments but didn't notice this. How can I receive the benefits without consuming any fish?
I used to eat a lot of swordfish and shark until the mercury levels were revealed. I haven't had either since the 1980's! I eat sardines because they do not have mercury. And other fatty fish I eat less than I used to. I grew up eating fish for almost every meal everyday. And I really want to eat fish everyday because it's my favorite food on the planet. The homemade chelating idea is intriguing.
@@nicknorwitzPhD yes it works with any camera, I use mine with my phone as a camera even. There's a guy on here does reviews of it, it's perfect for the stuff you do, so you don't need to keep looking off to the side
I wouldn’t eat them more than few times a year Besides the fact fish is unaffordable and eating the SMASH or some rainbow trout is hard enough to scrape together the $ for.

I followed your recipe link, but it was the plain mayo. The request was for the Chlorella + Cilantro sauce. I went and bought the Chlorella powder to make the sauce to go with Salmon tonight, but now I have no idea what to do with it!?! help please???
I eat about 1 can of sardines a week and maybe one portion of salmon or other seafood during the week. My Omega 3 index is 12.8. I have never taken omega supplements. It’s worth checking out the levels to know the baseline.
An O3 index of 17! Wow! I struggle getting past 6! It has been written that numbers around 4 are typical in the USA. My last test results should be back this next week. I slacked off the fish, so will actually be interesting to see what it is on carnivore! I am betting it will be low.
Salmon , sardines, or mackerel at least 3-5 times a week. Any cautions on canned? All wild caught. Dr. Berg says he tested canned and found no difference or dangers.
You can overdo Selenium, so that effectively it becomes toxic.. The (probably conservative) USA NIH Tolerable Upper Limit is 400 mcg/day. I seem to like selenium foods (seems like Nick does), but a bit of caution may be warranted. Similar here in the UK (the UK usually copies the USA). But Se helps greatly in Hg detox
Thanks Nick, for another wonderfully intriguing short video. I have a question... I know the LMHR phenotype has some specific Lipid markers but could a person potentially be a LMHR without the specific defined levels in the peer-reviewed paper? in other words, might the definition eventually broaden? I began low carb 1 year ago with near 258 Trigylcerides, 36 HDL, and 130-140 LDL... Dr. had put me on a statin which plummeted the LDL to near 60 but not as significant help for the other two numbers. Went low carb, quit the statin and triglycerides plummeted to about 58, HDL has shot up to 64 from 36 and ldl went to 130, then 152 and now 171... Trigly- is still currently 63 and HDL 64. I am suspecting I may be a LMHR. Had a CAC score of zero during this year's journey (also, my LDL has been 120-150 for 15 years plus and no one had really told me to worry as I was younger then I guess?). I also had carotid arteries scanned and no plaques. I see my doc tomorrow and I KNOW he is going to advocate for statin again but I'd prefer not but don't want to be disrespectful to him. I have printed Dr. Budoff and Dave and your study to give him to consider ahahahah. I know you are not my doctor and do not expect any medical advice, just wondering if you think I "might?" qualify as LMHR? Thanks for any engagement if you have time. :-) Stay curious my friend! :-)
@@nicknorwitzPhD you can put it skin side down, no oil, and the skin goes super crispy and eventually the fat renders out and then just finish it on the top side for a brief whilst its so good.

@@nicknorwitzPhD trust me, you will never get the skin as crispy as skin side down, no oil used. It doesnt burn easy either. You can almost cook the salmon right through
I eat a lot of fish yellow fin, sockeye, mahi, trout on occasion. I do spirulina most days and fresh cilantro on my food often but chlorella made me sick as a dog, puking at the big bowl.
Thank you for the video. I am a big fan. As usual, very informative. A few questions: Canned sardines in oil might have bad oils. Was this accounted for in the studies? Do you consider canned sardines in oil (omega 6 oils), to be any good? Also, I would love to know your thoughts about the best canned fish options, assuming I love all fish and don't mind eating canned sardines every day. Is more better, that is, twice per day? Two cans in one meal etc. Do you think there an upper doses? Can too much omega 3 be damaging? If someone doesn't eat fish at all, would you recommend omega 3 supplements? Thank you for the great video.
If you don't eat fish use the algae omega3 supplement. Taking fish based omega3 supplements is pointless. Avoid the soybean oil canned fish if you can, many options without it.
6 servings / month is moderate to high?? I eat 4 servings of fish per day. Every heavy metals test I’ve ever done has been in the normal range. I do heavily perspire every day from exercise, which helps.
Mercury is not a problem if it is consumed together with selenium because they bind and excrete, sardines being the sin with the most selenium, the only drawback that remains is micro and nanoplastics
Hello Nick. I found you on google newsfeed on your eggs experiment which I will post a question on that video after this lol. I love salmon, all seafood actually. Never had sardines but I do like anchovies. What’s your take on those? I researched it and read that anchovies were better in nutrients than sardines. So I am picking your brain. Also in past research I’ve read that any white fish is best for you outside of salmon of course due to the omegas. You have peaked my curiosity and am interested in hearing your take 😊. Thanks love your channel btw👍
Thank you so much for your informative health videos. You mentioned you eat olive oil every day. We mostly use Avocado oil since it has a higher smoke point. Is there much difference in terms of the health benefit between olive oil and avocado oil?
olive oil is better, its also better for frying. Avoid burning the hell out of your food if you care about your health though. "Wang references a 2018 study that compared olive oil with other oils during heating. It clearly showed that extra virgin olive oil is the most stable when heated, and produces the least amount of polar compounds (the harmful by-products that come from heating oils). In fact, all other vegetable oils high in polyunsaturated fats were found to produce more polar compounds when heated despite their high smoke points."
Just a heads up, the first study in the video is about cognition and the second study is for mortality, unlike what the video section labels and time stamps in the video description suggest.
The fish survived by itself in the ocean, and didn't we use to treat syphilis with mercury, and still people kive longer by eating fish, maybe they eat less soda, chips and fries. 🍟
Will dried fish retain the nutrients? Omega 3s, etc? How about fermented fish and fermented Krill? We have a lot of dried and fermented fish in the Philippines
Omega-3 fatty acids oxidise incredibly easily, so my bet is dried fish is likely to have lost most of the omega-3 content and may even come with some small health downsides due to the oxidised PUFA. Fermentation is a different story, effects possibly depends on the exact fermentation carried out. Anaerobic fermentation quite possibly could preserve the omega-3 fatty acids, but specific microbiota can sometimes transform the fatty acid profile of the substrate slightly: I've personally seen data indicating Rhizopus oryzae converts a significant quantity of substrate linoleic acid into stearic acid for example. I did some reading to answer your question with data rather than conjecture: the paper ["Lipid Degradation During Salt-Fermented Antarctic Krill Paste Processing and Their Relationship With Lipase and Phospholipase Activities"] shows the quantities of EPA and ALA in two fractions-- phospholipid fraction and triacylglycerol fraction --as fermentation progresses from 0 to 12 days. They show a total decrease in the omega-3's EPA and ALA of about 25% between day 0 and day 12 of fermentation in the phospholipid fraction, while in the triacylglycerol fraction the omega-3 content actually increases by nearly 100% by day 6 before falling back to its starting level at day 12. In net effect this would mean that a 12 day salt fermentation of krill paste would appear to have a significant decrease in omega-3's of the krill paste, but only by about 12.5% of the original value. I'll leave it up to someone else to confirm if dried fish has largely oxidised omega-3's or if they are somehow protected by the protein that surrounds them. :)
I have been avoiding salmon because I thought eating it daily would cause me to accumulate mercury and PCBs so I ate lean chicken breasts with olive oil, avocados, and supplemented with liquid fish oil instead. It's good to know that I might be able to incorporate more salmon in my diet again because I was getting tired of eating mostly chicken breasts with olive oil, avocados, broccoli, and Brussels sprouts. Macadamia nuts only increase my appetite, like other nuts, so I avoid eating them, and I actually do not like eating them because of it.
I don't know if you have looked at many studies on 100+ year olds but if you have anything to say about that topic I think it would make for an interesting video.
Grass fed beef also has high levels of omega 3, but we've been brain washed in to thinking "red meat" is bad. Plus creatine, taurine, even phytonutrients. Everything we're told is "good" is present in beef, but we're hammered with "science" that beef is bad. Its ludicrous.
@@nicknorwitzPhD you're taking about studies where people ate fish a handful of times a month, I eat 1-2lbs of grass fed beef per day. It adds up. I hate salmon and sardines. I'm also not mainlining omega 6's all day like most standard dieters either.
If you care about omega3 then eat beef liver, 3-4x the omega3 level. Red meat is not great in terms of overall nutrient profile, its no different than eating white flour and saying grains are healthy.
@@jaro6985 I literally ONLY eat red meat and a few eggs, I have very good levels of all nutrients I've had tested (including omega 3) and no deficiencies and no symptoms of deficiencies. Doing this I've resolved ALL of my health conditions which doctors told me were "age related" and there was nothing to be done they would just keep getting worse (or wanted me to take pills for).
I wish I liked fish. I tell myself "self...you need to like fish..eat fish, you will like it." I try it yet again and say. Oh my goodness I can't stand fish. How do ppl eat this? So I grab my Nordic Naturals cod liver 1Tbs... and call it a day. The krill oil is an interesting take, I may have to try that. Thanks Nick! HoM is STILL out of the 2.2lb bag...dude I'm dying here. You have any pull??
The smaller fish such as SMASH do not bioconcentrate as badly as the larger fish (i.e. tuna). Mackerel in particular is a very sustainable fish as it has low population turn over times.
How many grams of fish do you eat every day? I want to know how many grams are safe everyday (work low mercury first like sardines, salmon, and mackerel, etc.)
Would you please talk more about why you measured your mercury levels? Were you just curious? Did you have a suspicion that maybe your mercury levels were high? I presume the units you were talking about were µg/L, yes? Reference range appears to be between 0 and 15, so that fits with what you said in your video. Also, would you please elaborate more about chelation with chlorella and cilantro? I would like to learn more about this. Thanks.
Whenever I see Cookie Monster, I think of this: 'Cookie Monster love high fructose corn syrup!' 'OM NOM NOM NOM!' 'Oh no, Cookie Monster don't feel very good'
With time I expect Omega 3 levels in fish will likely be stable. Our waterways are getting more heavy metal rich. How selenium might vary with time is beyond my pay grade. So I expect the double edge sword aspect of wild caught fish will likely deteriorate.
As we reduce coal fired power station use it should start to taper off, as that is the largest single source, responsible for about 40% of US emissions for example.
I would like to ask you if it is possible that Omega 3 fatty acid supplements have negative effects on our brain? I take one 1000mg capsule a day and feel that the omega 3 supplement is having a rather negative effect on my brain. Thank you

The olive oil would push the dirt out of the pores and the caked oil on the body's surface was then scraped away.
To your point though, fraud is rampant in the olive oil business. There is said to be more olive oil sold than is produced. I wouldnt worry if you are getting a good quality oil...before I went Carnivore, I used Barani here in the USA...but the fraud is likely when you see olive oil as an j gredient i canned or packaged foods.
@@chazwyman I replied to you but I dont see my reply. Is it visible to you?
Fish absorb mercury and other heavy metals from the water they swim in, and the amount of mercury in a fish's body increases over time as it consumes other fish. This process is called biomagnification, and it means that larger, longer-lived fish like tuna tend to accumulate more mercury in their bodies than smaller, shorter-lived fish like sardines. This is why I mostly eat sardines. I do however eat salmon when I am certain that is wild caught and not farm raised. Farm raised fish are fed corn and grain products. In the wild they get their omega-3s from eating algae or eating other fish that eat algae.
Anchovies are good too
And mackerel is cheap
@@YeshuaKingMessiah Agreed!
Yes, trophic level is a factor. Hence... be wary of swordfish/shark etc. But there are other factors, as noted in the first paper
@@YeshuaKingMessiah I actually prefer mackerel to sardines, though I eat both.
You are wrong. They get mercury from eating Amother mercury contaminated fish.
I'm vegan and a senior. Some of my friends/family are passing, and I'm still hiking and snorkeling. You don't have to eat ANY animals to be healthy. Jeannine
I’m happy you’re doing well :).
mouth watering food pics! :)
I love fish, but all the lead/heavy metal stuff greatly worries me. I've read about far more than one case of someone who was inexplicably ill until they stopped eating fish multiple times per week and in the end it turned out to be some sort of metal poisoning.
Do as you will.
I've read that the selenium in fish we consume (tuna, salmon and sardines) can be a good way to effectively counteract the heavy metal issues.
@@flipino007a
Well the fish survived by itself in the ocean. Then people eat chips and fries 🍟 insted 😂😂😂
@@Myrslokstok heavy metal makes you more aggressive and less inclined to eat fish and chips...I believe it's the best and cadence of the drums that incline many listeners to resort to aggression.
I was eating fish at least once a day. A large portion was canned albacore. My Mercury score came in at 15mcg/L (normal
Ya... if you're going to eat fish everyday, I wouldn't make it tuna. I'm a big sardine fan! Also, catfish 'nuggets' (cutoffs) at Star ar $4/lbs and fry up great! coat in egg wash and whey and it kinda tastes like 'fish&chips'
I never tested...but learnt along the way to only get the skipjack tuna. It's a smaller fish, minimal mercury compared to Albacore
Lot of freshwater is full of PFAS. You can't really win.
"EWG study: Eating one freshwater fish equals a month of drinking ‘forever chemicals’ water"
The only fish I like to eat is canned tuna haha! But I do choose skipjack tuna which should be lower mercury, at least it's better than no fish, I really don't like the taste of most fishes
Nick, love your informative videos! Fish - I am highly allergic. Scanned comments but didn't notice this. How can I receive the benefits without consuming any fish?
Thank you! I eat a lot of fish . . . now I'll add in krill oil.
I used to eat a lot of swordfish and shark until the mercury levels were revealed. I haven't had either since the 1980's! I eat sardines because they do not have mercury. And other fatty fish I eat less than I used to. I grew up eating fish for almost every meal everyday. And I really want to eat fish everyday because it's my favorite food on the planet. The homemade chelating idea is intriguing.
How about omega 3 from shrimp and other seafoods. Krill? We have a lot of fermented Krill in the Philippines
I like how he makes and subsequently accepts his own challenge, DHA.
LOL! Yeppers!
In the first study, it's possible you have the causation reversed. Perhaps smart people simply eat more fish.
Nick, your content is awesome, consider getting an Elgato teleprompter, I got one a week ago & it is so good, takes everything to the next level
Thanks for the tip! Will it work with Sony alpha 6700 camera?
@@nicknorwitzPhD yes it works with any camera, I use mine with my phone as a camera even. There's a guy on here does reviews of it, it's perfect for the stuff you do, so you don't need to keep looking off to the side
Ok, I won’t eat swordfish and sharks every day now
I wouldn’t eat them more than few times a year
Besides the fact fish is unaffordable and eating the SMASH or some rainbow trout is hard enough to scrape together the $ for.
Lol... Bruce (from Memo) will be happy to hear it.
Will you, please, publish (RUclips or other) your Broken Cell Chlorella- Cilantro Mayonnaise recipe? Sounds yummy and would go perfect with fish.
This recipe from Martina w/ Macadamia oil (house of macadamia for the macadamia oil: www.houseofmacadamias.com/pages/nick-norwitz) ; you can use NICK10 for discount)+ chlorella. ketodietapp.com/Blog/lchf/Healthy-Home-made-Mayo-Three-Ways
I followed your recipe link, but it was the plain mayo. The request was for the Chlorella + Cilantro sauce. I went and bought the Chlorella powder to make the sauce to go with Salmon tonight, but now I have no idea what to do with it!?! help please???
I just discovered that grass fed lamb has 3x more omega3 compare to beef so I replace ground beef meals with ground lamb
🤮
But what's the absolute amount?
@@nicknorwitzPhD2-10+ times less than good seafood products, depending who is measuring it. I eat 2.5 pounds of meat per day so it’s great
Interesting because I always add lamb rump fat (the tail fat) to my ground beef to make taste better.
I eat about 1 can of sardines a week and maybe one portion of salmon or other seafood during the week. My Omega 3 index is 12.8. I have never taken omega supplements. It’s worth checking out the levels to know the baseline.
12.8 is awesome!
Not as good as Nick tho
An O3 index of 17! Wow! I struggle getting past 6! It has been written that numbers around 4 are typical in the USA. My last test results should be back this next week. I slacked off the fish, so will actually be interesting to see what it is on carnivore! I am betting it will be low.
Salmon , sardines, or mackerel at least 3-5 times a week. Any cautions on canned? All wild caught. Dr. Berg says he tested canned and found no difference or dangers.
You can overdo Selenium, so that effectively it becomes toxic.. The (probably conservative) USA NIH Tolerable Upper Limit is 400 mcg/day. I seem to like selenium foods (seems like Nick does), but a bit of caution may be warranted. Similar here in the UK (the UK usually copies the USA). But Se helps greatly in Hg detox
Great info thanks Nick! Do you have an omega 3 index test provider that you prefer or recommend?
Thanks Nick, for another wonderfully intriguing short video. I have a question... I know the LMHR phenotype has some specific Lipid markers but could a person potentially be a LMHR without the specific defined levels in the peer-reviewed paper? in other words, might the definition eventually broaden? I began low carb 1 year ago with near 258 Trigylcerides, 36 HDL, and 130-140 LDL... Dr. had put me on a statin which plummeted the LDL to near 60 but not as significant help for the other two numbers. Went low carb, quit the statin and triglycerides plummeted to about 58, HDL has shot up to 64 from 36 and ldl went to 130, then 152 and now 171... Trigly- is still currently 63 and HDL 64. I am suspecting I may be a LMHR. Had a CAC score of zero during this year's journey (also, my LDL has been 120-150 for 15 years plus and no one had really told me to worry as I was younger then I guess?). I also had carotid arteries scanned and no plaques. I see my doc tomorrow and I KNOW he is going to advocate for statin again but I'd prefer not but don't want to be disrespectful to him. I have printed Dr. Budoff and Dave and your study to give him to consider ahahahah. I know you are not my doctor and do not expect any medical advice, just wondering if you think I "might?" qualify as LMHR? Thanks for any engagement if you have time. :-)
Stay curious my friend! :-)
i love nz salmon. I live in nz and the salmon, yes farmed, is the best salmon I have tasted anywhere around the world.
You’re so right! NZ Ora salmon is the best y I’ve ever had
@@nicknorwitzPhD you can put it skin side down, no oil, and the skin goes super crispy and eventually the fat renders out and then just finish it on the top side for a brief whilst its so good.

Can we get a detailed video on your diet?
I eat a lot of fish yellow fin, sockeye, mahi, trout on occasion. I do spirulina most days and fresh cilantro on my food often but chlorella made me sick as a dog, puking at the big bowl.
Thank you for the video. I am a big fan. As usual, very informative. A few questions: Canned sardines in oil might have bad oils. Was this accounted for in the studies? Do you consider canned sardines in oil (omega 6 oils), to be any good? Also, I would love to know your thoughts about the best canned fish options, assuming I love all fish and don't mind eating canned sardines every day. Is more better, that is, twice per day? Two cans in one meal etc. Do you think there an upper doses? Can too much omega 3 be damaging? If someone doesn't eat fish at all, would you recommend omega 3 supplements? Thank you for the great video.
If you don't eat fish use the algae omega3 supplement. Taking fish based omega3 supplements is pointless.
Avoid the soybean oil canned fish if you can, many options without it.
6 servings / month is moderate to high?? I eat 4 servings of fish per day. Every heavy metals test I’ve ever done has been in the normal range. I do heavily perspire every day from exercise, which helps.
Lucky you!
Mercury is not a problem if it is consumed together with selenium because they bind and excrete, sardines being the sin with the most selenium, the only drawback that remains is micro and nanoplastics
Lol at your thumbnail 😂 Really appreciate your time & effort in all of your vids ❤
Thank you very much! Friend made the thumbnail. I love it too!
Iodine and astaxanthin might be important too.
Astaxanthin is a very interesting compound... enjoy some Sockeye!
Thanks for showing via statistcs that my dirt is good for me.
I meant diet..ty for supporting data my food is good for me
Um... what? I'm missing something here...
@@Andrea-u2f 🤣 makes more sense
I think the major problem with seafood is it’s a cesspool of poison and I believe that smal canned fish are oxidized during the canning process
I loved the canned smoked herring. Are those Omega 3's still good? Or do they get oxidized?
Hello Nick. I found you on google newsfeed on your eggs experiment which I will post a question on that video after this lol. I love salmon, all seafood actually. Never had sardines but I do like anchovies. What’s your take on those? I researched it and read that anchovies were better in nutrients than sardines. So I am picking your brain. Also in past research I’ve read that any white fish is best for you outside of salmon of course due to the omegas. You have peaked my curiosity and am interested in hearing your take 😊. Thanks love your channel btw👍
Ok - now I need your mayo recipe!!! Sounds like a good addition- although is chlorella tasty?
Thank you so much for your informative health videos. You mentioned you eat olive oil every day. We mostly use Avocado oil since it has a higher smoke point. Is there much difference in terms of the health benefit between olive oil and avocado oil?
olive oil is better, its also better for frying. Avoid burning the hell out of your food if you care about your health though.
"Wang references a 2018 study that compared olive oil with other oils during heating. It clearly showed that extra virgin olive oil is the most stable when heated, and produces the least amount of polar compounds (the harmful by-products that come from heating oils). In fact, all other vegetable oils high in polyunsaturated fats were found to produce more polar compounds when heated despite their high smoke points."
Just a heads up, the first study in the video is about cognition and the second study is for mortality, unlike what the video section labels and time stamps in the video description suggest.
i wonder if we compare fish eaters with Meat eaters will the memory test results be different ? Thanks nick ..
I'm happy to go toe-to-toe with any Lion diet eater or fish free carnivore... BRING IT!
What do you look for when you purchase your olive oil ( i.e what makes you trust some brands more than others at providing pure olive oil )?
2 fishes per day? Bro is 2 marlins away from mercury poisoning!
Sardines ftw
Wizards cause Hg poisoning!?!?
😂😅@@rpearce25
Marlin? Or am I a Wizard?
It would be nice to have some deep dive in out diet somewhen :)
The fish survived by itself in the ocean, and didn't we use to treat syphilis with mercury, and still people kive longer by eating fish, maybe they eat less soda, chips and fries. 🍟
Will dried fish retain the nutrients? Omega 3s, etc? How about fermented fish and fermented Krill? We have a lot of dried and fermented fish in the Philippines
Omega-3 fatty acids oxidise incredibly easily, so my bet is dried fish is likely to have lost most of the omega-3 content and may even come with some small health downsides due to the oxidised PUFA. Fermentation is a different story, effects possibly depends on the exact fermentation carried out. Anaerobic fermentation quite possibly could preserve the omega-3 fatty acids, but specific microbiota can sometimes transform the fatty acid profile of the substrate slightly: I've personally seen data indicating Rhizopus oryzae converts a significant quantity of substrate linoleic acid into stearic acid for example.
I did some reading to answer your question with data rather than conjecture: the paper ["Lipid Degradation During Salt-Fermented Antarctic Krill Paste Processing and Their Relationship With Lipase and Phospholipase Activities"] shows the quantities of EPA and ALA in two fractions-- phospholipid fraction and triacylglycerol fraction --as fermentation progresses from 0 to 12 days.
They show a total decrease in the omega-3's EPA and ALA of about 25% between day 0 and day 12 of fermentation in the phospholipid fraction, while in the triacylglycerol fraction the omega-3 content actually increases by nearly 100% by day 6 before falling back to its starting level at day 12.
In net effect this would mean that a 12 day salt fermentation of krill paste would appear to have a significant decrease in omega-3's of the krill paste, but only by about 12.5% of the original value.
I'll leave it up to someone else to confirm if dried fish has largely oxidised omega-3's or if they are somehow protected by the protein that surrounds them. :)
@@danielkruyt9475
How about fermented fish?
I have been avoiding salmon because I thought eating it daily would cause me to accumulate mercury and PCBs so I ate lean chicken breasts with olive oil, avocados, and supplemented with liquid fish oil instead.
It's good to know that I might be able to incorporate more salmon in my diet again because I was getting tired of eating mostly chicken breasts with olive oil, avocados, broccoli, and Brussels sprouts.
Macadamia nuts only increase my appetite, like other nuts, so I avoid eating them, and I actually do not like eating them because of it.
I live in an inland state where cows eat grass. Quality fish starts at $28/pound. It financially difficult to overeat fish.
I live in the desert, no fish here. When I moved here from the east coast I just stopped eating it.
I think that generally in the Mediterranean countries we eat more fish than in the US and a large variety also.
I enjoy brisling sardines and mackerel 🤗
Nick, what do you use for oil in your homemade mayonnaise?
Mostly macadamia oil from House of Macadamia. They’re a partner and I love their products. My discount code is NICK10

Thanks! I guess I am a RUclipsr now... kinda' funny to think.
I don't know if you have looked at many studies on 100+ year olds but if you have anything to say about that topic I think it would make for an interesting video.
a very good one
Thanks :)
Grass fed beef also has high levels of omega 3, but we've been brain washed in to thinking "red meat" is bad.
Plus creatine, taurine, even phytonutrients. Everything we're told is "good" is present in beef, but we're hammered with "science" that beef is bad. Its ludicrous.
Not really that much omega-3... not compared to something like salmon or sardines.
@@nicknorwitzPhD you're taking about studies where people ate fish a handful of times a month, I eat 1-2lbs of grass fed beef per day. It adds up. I hate salmon and sardines.
I'm also not mainlining omega 6's all day like most standard dieters either.
If you care about omega3 then eat beef liver, 3-4x the omega3 level.
Red meat is not great in terms of overall nutrient profile, its no different than eating white flour and saying grains are healthy.
@@jaro6985 I literally ONLY eat red meat and a few eggs, I have very good levels of all nutrients I've had tested (including omega 3) and no deficiencies and no symptoms of deficiencies.
Doing this I've resolved ALL of my health conditions which doctors told me were "age related" and there was nothing to be done they would just keep getting worse (or wanted me to take pills for).
Careful with the large fish, smaller short lived fish can be safer for you. If you eat fish, you will remember to eat fish btw. 😊
I wish I liked fish. I tell myself "self...you need to like fish..eat fish, you will like it." I try it yet again and say. Oh my goodness I can't stand fish. How do ppl eat this? So I grab my Nordic Naturals cod liver 1Tbs... and call it a day. The krill oil is an interesting take, I may have to try that. Thanks Nick! HoM is STILL out of the 2.2lb bag...dude I'm dying here. You have any pull??
The smaller fish such as SMASH do not bioconcentrate as badly as the larger fish (i.e. tuna). Mackerel in particular is a very sustainable fish as it has low population turn over times.
Does dried fish retains omega 3? We have lots of dried seafoods in the Philippines.
How about fermented fish?
How many grams of fish do you eat every day? I want to know how many grams are safe everyday (work low mercury first like sardines, salmon, and mackerel, etc.)
Would love your recipe for mayo with cilantro.
I love spearfishing and I love fish 🐟 😋
Thanks, Nick . How about beef bison goat, and cheap?
What about the correlation of of higher DHA = higher occurrence of prostate cancer?
Would you please talk more about why you measured your mercury levels? Were you just curious? Did you have a suspicion that maybe your mercury levels were high? I presume the units you were talking about were µg/L, yes? Reference range appears to be between 0 and 15, so that fits with what you said in your video. Also, would you please elaborate more about chelation with chlorella and cilantro? I would like to learn more about this. Thanks.
You mentioned you consume a lot of olive oil, is there a specific brand you trust to be pure and not oxidized?
What are good types of fish that are okay to eat everyday because of mercury levels ?
Whenever I see Cookie Monster, I think of this:
'Cookie Monster love high fructose corn syrup!'
'OM NOM NOM NOM!'
'Oh no, Cookie Monster don't feel very good'

With time I expect Omega 3 levels in fish will likely be stable. Our waterways are getting more heavy metal rich. How selenium might vary with time is beyond my pay grade. So I expect the double edge sword aspect of wild caught fish will likely deteriorate.
As we reduce coal fired power station use it should start to taper off, as that is the largest single source, responsible for about 40% of US emissions for example.
Sea salt may include relatively higher dosages of micro- and nanoplastics
I would like to ask you if it is possible that Omega 3 fatty acid supplements have negative effects on our brain? I take one 1000mg capsule a day and feel that the omega 3 supplement is having a rather negative effect on my brain. Thank you
