My background is physics, chemistry, math and automatic control theory. The chemistry part you have is great because it is so informative.

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.
I love fish daily and strive to use tins of sardines for their easy availability and low mercury levels. Salmon is readily available. I used to take fish oil epa and dha supplements, but since I am on Eliquis, my doctors frowned on taking these supplements. Most physicians frown on this in spite of spotty studies that prove their position. I have a degree in nutritional biochemistry and was a practicing physician for decades. There just is even less data in the medical literature on fish daily consumption and resulting omega 3 intake in relation to taking anticoagulants. 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
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.
A few Vegetarians in the past have to hated on me for being pescetarian _(even though in those Adventist studies they adore so much it’s revealed in the full study pescetarians had a mildly lower mortality risk than vegans but both had a moderately-to-majorly lower mortality risk than vegetarians)_ but it’s actually not hard in the modern era to figure out which fish/bivalves are safe & healthiest, to find lists of low/marginal contamination species, which certifiers of sustainability/responsible catching standards are revered and you can just simply taking high quality selenium supplements detoxifies heavy metals from the body Been a pescetarian for 6+ years but I only eat 1.5-2.5 servings of seafood (fish/bivalves) per week. Which isn’t more often than I had it before opting for a pescetarian diet but I pick far better options now ❤ I’ve gone consecutive months in the past without fish and I don’t feel up to 100%.

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.
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.
The best way for me to get a bit of fish each day, is a small tin of mackerel. It has a slightestly better nutrient profile than a similar tin of sardines and tastes better. I chose the one with olive oil and eat it with a polish hot mustard which has no preserves or additives.
@@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.

Many thanks for all your good work. Susan
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 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.
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
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. :)
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.
Another brilliant info video....One day do a video where u bring the last few videos together....There is lot of good info here.. Thank you ... deeply appreciated.
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.
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?
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.
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👍
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.
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.
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.
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.
@@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
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.
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.
Had a CIMT scan a few weeks ago, it showed a lot of soft plaque. Been doing a deep dive on how to move forward. Being on a blood thinner(Eliquis) limits what I can do to lower my inflammation with supplementation. Are there any studies out there showing using a low dose Statin to lower inflammation?
Yes, I do need to eat more fish weekly but I’m not sure about daily. Have you always enjoyed eating fish or did you develop a desire for it? If you developed the desire, what was the mechanism you used to increase your desire?
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.)
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.
I left boxing 8 years ago because of possible neurological issues (dysphemia) and even back then fish oil (for its DHA content) was connected with brain function so on my own I started taking 2 Tbsp/day of fish oil (totaling 7g total omega 3 daily) and thought nothing of it but lately some reports suggested it's correlated with increased risk of stroke so I've been concerned about taking so much. How is this possible since I' sure some heavy fish eaters get that much and they don't seem to be at risk?
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."
It's a concern perhaps for those taking supplements, as that's what the study was based on right? Also it found in increase in arythmias, but a decrease in cardiac arrest right?
@terraflow__bryanburdo4547 Agreed, oxidized fats seem to be much much more dangerous than anyone realized. Another study just came out showing oxidized fats in feed for mice cause huge amounts of mitochondrial damage compared to unoxidized. But now I'm left with seeing how I know whether a fat is oxidized or not? Is the fat in the fish I cooked on the grill oxidized? What about the fat in the ribeye in the fridge I cooked four days ago? Is that oxidized? How about the jars of ghee I have around the house?
To offset the healthy user bias, they should do a study in a place like northern Wisconsin, where there are plenty of unhealthy people who love to eat fish.
How about fish or krill oil supplements (high quality ones that have been tested for oxidation)? I dont want to risk ingesting the pollutants that can come with fish. Could fish/krill oil supplements be taken daily instead of eating fish? Isn't it mostly the omega 3 oils that are responsible for the positive effects?
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.
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

Thank you so much for your videos. I am learning so much. My mother died of AD and I am looking for ways to lose my risk. You mentioned krill oil in one of your other videos. Could you recommend a brand that you trust and where to purchase it. I have heard that Amazon is not always the best source for supplements, so I avoid ordering them from them. Many thanks for all your good work. Susan
Great information. Your approach and information niche is perfectly targeted for my interests.
Glad it was helpful!
Sea salt may include relatively higher dosages of micro- and nanoplastics
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! :-)
Great info thanks Nick! Do you have an omega 3 index test provider that you prefer or recommend?
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!
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.
mouth watering food pics! :)
Nick, what is your protein and fat percentage? 80/20 or something else 😊
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
Thank you! I eat a lot of fish . . . now I'll add in krill oil.
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!
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. :)

How about fermented fish?
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.
Another brilliant info video....One day do a video where u bring the last few videos together....There is lot of good info here.. Thank you ... deeply appreciated.
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 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.
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?
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
What about the PFAS and other toxicants in fish these days?
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.
Tell more about your diet!! :D
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👍
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!
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
Would love your recipe for mayo with cilantro.
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 )?
What about the correlation of of higher DHA = higher occurrence of prostate cancer?
i love eating fermented atlantic mackerel with raw cultured cream. so tasty!
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?
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.
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.

@@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
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.
is canned fish as healthy as fresh one?
Does dried fish retains omega 3? We have lots of dried seafoods in the Philippines.
How about fermented fish?
What are good types of fish that are okay to eat everyday because of mercury levels ?
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.
Had a CIMT scan a few weeks ago, it showed a lot of soft plaque. Been doing a deep dive on how to move forward. Being on a blood thinner(Eliquis) limits what I can do to lower my inflammation with supplementation. Are there any studies out there showing using a low dose Statin to lower inflammation?
Yes, I do need to eat more fish weekly but I’m not sure about daily. Have you always enjoyed eating fish or did you develop a desire for it? If you developed the desire, what was the mechanism you used to increase your desire?
I've always loved fish... I think when I was 12 months old I would grab Ahi tuna over candy
For me it was an aquired taste. The more I eat it, the more I like it.
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.)
It would be nice to have some deep dive in out diet somewhen :)
What is your take on Uric acid? Mine gets pretty high if I eat more than 3 cans a week. And no, I eat virtually no fructose...
I'm curious, do you have any idea how long it takes for one's omega levels to increase when adding fish every day to one's diet?
Due you have an omega 3 deadline to meet?
How bioavailable are the nutrients in nuts?
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.
I left boxing 8 years ago because of possible neurological issues (dysphemia) and even back then fish oil (for its DHA content) was connected with brain function so on my own I started taking 2 Tbsp/day of fish oil (totaling 7g total omega 3 daily) and thought nothing of it but lately some reports suggested it's correlated with increased risk of stroke so I've been concerned about taking so much. How is this possible since I' sure some heavy fish eaters get that much and they don't seem to be at risk?
Fish oil is oxidized. Oxidation = disease
Oxidized supplements v. Unoxidized fish
Good question.
Any difference between fresh water fish with salt water fish on omega 3?
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."
You mentioned you consume a lot of olive oil, is there a specific brand you trust to be pure and not oxidized?
The best UA-camr
Thanks! I guess I am a UA-camr now... kinda' funny to think.
What about the research paper that recently made rounds in a lot of channels about increased arrhythmia risk with high omega 3 intake?
It's a concern perhaps for those taking supplements, as that's what the study was based on right? Also it found in increase in arythmias, but a decrease in cardiac arrest right?
Probably oxidized supplements
@terraflow__bryanburdo4547
Agreed, oxidized fats seem to be much much more dangerous than anyone realized. Another study just came out showing oxidized fats in feed for mice cause huge amounts of mitochondrial damage compared to unoxidized.
But now I'm left with seeing how I know whether a fat is oxidized or not? Is the fat in the fish I cooked on the grill oxidized? What about the fat in the ribeye in the fridge I cooked four days ago? Is that oxidized? How about the jars of ghee I have around the house?
@@NutritionPolice I eat most of my beef raw now and feel amazing. Sardines in water only. Sniff test is reliable for me. YMMV

To offset the healthy user bias, they should do a study in a place like northern Wisconsin, where there are plenty of unhealthy people who love to eat fish.
Ok - now I need your mayo recipe!!! Sounds like a good addition- although is chlorella tasty?
How about fish or krill oil supplements (high quality ones that have been tested for oxidation)? I dont want to risk ingesting the pollutants that can come with fish. Could fish/krill oil supplements be taken daily instead of eating fish? Isn't it mostly the omega 3 oils that are responsible for the positive effects?
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.
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
