Avoiding Fish for 5 Years Before Pregnancy

The problem with fish advisories that tell pregnant women to cut down on fish is that it may be too late for certain persistent pollutants.

In my previous video on this topic, How Long to Detox from Fish Before Pregnancy (https://nutritionfacts.org/video/how-long-to-detox-from-fish-before-pregnancy), I mentioned a study that suggests detoxing from fish for one year to see mercury levels decrease, but other pollutants take longer to leave our system.

There are also non-pollutant reasons may want to avoid excessive amounts of any animal protein. See: The Effect of Animal Protein on Stress Hormones, Testosterone, and Pregnancy (https://nutritionfacts.org/video/the-effect-of-animal-protein-on-stress-hormones-testosterone-and-pregnancy).

70 Risposte a “Avoiding Fish for 5 Years Before Pregnancy”

  1. Fish has become disgusting. I noticed the difference in taste prior to going plant based and I did my best to consume 'wild caught' salmon and tuna. We've turned our oceans and seas into toilet bowls.

  2. If a woman were to do a Mercury, etc detox (i.e. chlorella, cilantro, bentonite clay, activated charcoal, essiac tea) during breastfeeding, would that pose a risk to the child?

  3. Humans have been very destructive to the earths plants and animals.
    We are destroying the very eco systems we need to survive.
    The Climate Crisis is waking people up to the destruction of the planet.
    Will we do anything to stop the poisoning of the planet and the eco systems we need to survive.
    Young people seem to get it and want a better future. Older adults view the world from how it was in the past.
    Individuals, corporations and politicians all need to make changes to reduce the impact of the Climate Crisis.

  4. So where is the human brain to get its supply of DHA from (and please don't mention ALA with its piss-poor conversion rates), and why is fish consumption correlated with slower rates of cognitive decline ?

  5. But Dr, why present mechanistic data of what happens when you eat fish, how the pollutants get more concentrated in the blood.
    What is interesting is OUTCOME data, show us that increase in fish consumption is associated with disease, toxicity etc.
    Who cares if you have more mercury in the brain if you don't show us that is cuts your life short

  6. I am trying very hard to make the people I know stop eating fish but it is hard for them to fathom that fish is unhealthy. This false Omega 3 needs is making everyone poisoned.

  7. The problem with pregnant women, is that the root cause of the Anthropocene mass extinction, anthropogenic climate change, factory farming, and industrial fishing; is human overpopulation.

  8. "Detox" mercury in the blood is 100days IF you fed yourself fish for 100days… What if it is years. Because it seems the graph did not reach its max.

  9. I wonder about amalgam in your fillings? I still have fillings and am 53. If I get them out tomorrow, would it be 27 years before it to detox my brain, too? 🙁

  10. The problem with this one is it treats all fish as having equal amounts of mercury, after starting with Tuna, which is at the top of the chain (and the most polluted).

  11. I could listen to your voice all day !
    You are getting REALLY GOOD at public speaking , Sir !
    Thank you for your brilliant mind and kind heart !!

  12. I used to dine at japanese restaurants at least once a week…that’s where most of my seafood consumption came from 🤦🏻‍♂️Thank goodness i’m now on a 100% plant based diet and my health’s skyrocketing 🚀 🌿

  13. Dr. Greger, I have a question. So clearly all fish from the oceans and from farms are highly toxic to consume. What about fish found in lakes in Canada? Here is legal to fish and there are a lot of lakes that are really far from all those contaminants that sadly reach the oceans.
    I'll would love some information about that subject. Thank you

  14. Ironically my endocrinologist is suggesting that I eat fish and chicken, and eat foods in the most simplest of forms was her suggestion…. so who do you believe. That's why people get so damn confused.

  15. Why only before pregnancy? Aren't these substances toxic to everyone? And the mercury in the Brian thing has nothing to do with pregnancy. I think this video needs a new title.

  16. … And stay away from vaccines – mercury in baby vaccines and aluminum is still in flu vaccines. The unvaccinated children are significantly healthier ie no ear infections; excema, asthma and immune conditions are more rare.

  17. Do those acronyms for pollutants in fished vs wild salmon include mercury? What's the difference between wild and farmed? Where would farm raised even get mercury from?

  18. Yeah that's why all the fish eating coastal communities are so unhealthy and live such short lives….. Oh wait.

    Also, he completely misses that sardines, salmon, shellfish, etc have almost NO Mercury. There is a huge difference between eating yellowfin tuna and salmon since wild caught salmon has almost no Mercury. Or even light tuna which is much lower.
