  1. Whoever is reading and going through hard times, depression, sucidal thoughts, trauma and frustration. Dont give up. It doesnot matter how bad things are in your life. You will win. You are a fighter and stronger than you think.

  2. What's the best Vegan Omega 3 supplement available on Amazon UK? Nordic Naturals has the best Labdoor score but it's ridiculously pricey, does anyone know if Algae Omega 3 is less prone to oxidation?

  3. Good to know this, thanks. However it would be even better if to make sure that the negative effects are due To contaminants a similar high level of omega3 from plant sources was tested. Further subdividing for omega3 from plant foods and marine flora derived supplements.

  4. I’ve never liked seafood—except for the random tuna sandwich in my youth—with a side of Campbell’s tomato soup! 🤣🤣🤗

  5. Taking cod liver oil – not "fish oil" is easily the best Thing I've done for my Health. I can only recommend it. Just be Aware that so-called fish oil is not the same as cod liver oil.

  6. Hi dr. Have a question about flaxseed. A little birdie told me that flaxseed raises cortisol which in turn blocks testosterone. Even if you have high testosterone the cortisol just blocks it?

  7. So no, it is not brain food for older adults. Really glad I don't eat seafood unless you count seaweed. Thanks again for this information.

  8. Thanks for the awesome video! Your research is amazing. Your videos always inspire me to keep posting on my channel!

  9. You can buy highly purified fish oil which will have little to no trace of these heavy metals. Yes, trials on supplementation of fish oil have proved underwhelming, but if you look at the studies the supplementation is like, 1 pill a day, which is tiny. Does dr greger think omega 3s aren’t all they’re cracked up to be? Because that would be contradictoring his earlier statements. I take algae oil, a lot of it.

  10. Well, Omega 3 has another side effect, it deactivates the SIRT1 pathway which may switch off our best cancer prevention mechanism.

    I opt for Flaxseed Oil, which not only has Alpha Linoleic Acid which can convert to omega 3, naturally through various ways in the body. The other advantages being :

    Flaxseed ground meal at 40 gram per day can reduce Lp(a) , a gene that is active in ½ of Indians and ⅓ of Americans that makes people in India prone to heart attacks through blockage.

    Flaxseed is the richest source of Lignans another cancer prevention item.

  11. Hey everyone I’m in a nutrition class at my college and my teacher who is a dietitian recommends seafood bacon and grass fed beef what would be the right way to approach about evidence like this?

  12. The studies you are referencing are specifically talking about mercury, no? i.e. the same outcomes may not be observable in quality assured omega 3 fatty acid consumption

  13. Fish has reduced cholestrol and increased focus and span …. salmon three time a week is good for heart, brain and pain in joints .
    Japan and medeterrian are high consumption n. Fish and there heart health is better than anybody .
    High carb vegan diet cause inflammation , tiredness , joint pain and foggy ness. I believe good healthy protein like fish is good for you. Using lots of bean and lentil my weight was higher, cholestrol too and cause me hypothyroid …. change to tons of veggies, moderate nuts and sees, salmon and less sugary fruit .
    But I believe diet is also has to suit you.

  14. Speaking from experience, there is no question whether DHA helps with depression. It does. I'm willing to bet the issue is those studies either weren't using enough DHA or they were using an inferior form (i use a liposomal vegan one–conventional liquid DHA is nothing to get excited about in my experience). DHA is amazing!

  15. >>>Investigators assessed dementia-related pathologies, including Alzheimer’s disease, Lewy bodies, and the number of macroinfarcts and microinfarcts. They measured tissue concentrations of mercury and selenium using instrumental neutron activation analyses in a subsample of 203 cases.
    As in prior studies, seafood consumption did not correlate with Alzheimer’s disease outcomes in a linear way, and the investigators only presented findings where seafood was modeled as an indicator variable (ie, one or more meals per week vs less). After adjusting for age, sex, education, and total energy intake, eating one or more seafood meals per week was significantly associated with less Alzheimer’s disease pathology, including lower density of neuritic plaques and less severe and widespread neurofibrillary tangles in APOE ε4 carriers. Brain mercury levels positively correlated with the number of seafood meals consumed per week, but levels did not correlate with neuropathology. “To our knowledge, this is the first study to report on the relationship between brain concentrations of mercury and brain neuropathology or diet,” said Dr. Morris and colleagues. “The finding of no deleterious correlations of mercury on the brain is supported by a number of case–control studies that found no difference between Alzheimer’s disease patients and controls in mercury concentrations in the brain, serum, or whole blood.<<< Association of Seafood Consumption, Brain Mercury Level, and APOE ε4 Status With Brain Neuropathology in Older Adults

  16. What about plant based Omegas? Like chia seeds and ahiflower? Do safe Omegas have any place in our diet?

  17. How about FDA-approved doses of prescription n-3 FA products made from fish oils? My blood test showed EPA DHA levels out of balance but triglycerides are normal. I would not be eligible for prescription medications. Unregulated over the counter pill pushers are not to be trusted.

  18. Same time you have study show benefit on longevity, so we can choose between 5% more life or 5% less brain.. 🙄Maybe the solution is eat fish from the river not from the sea

  19. In the very near future we will be able to get EPA and DHA Omega 3 from a completely plant based source without the risk of Mercury. Camelina sativa has been genetically modified to produce EPA and DHA. Source: https://www.nutraingredients.com/Article/2017/07/28/GM-plant-derived-omega-3-successfully-cultivated-on-commercial-scale
