Here’s the “daily dozen” thing I mentioned: Dr. Greger’s Daily Dozen Checklist (https://nutritionfacts.org/video/dr-gregers-daily-dozen-checklist/).

Of course this is not the only reason to make sure you get enough vitamin B12. See, for example, Vitamin B12 Necessary for Arterial Health (https://nutritionfacts.org/video/vitamin-b12-necessary-for-arterial-health/). I recommend 2500 micrograms once a week of a cyanocobalamin supplement, though there’s also a toothpaste (https://www.ncbi.nlm.nih.gov/pubmed/30680547) that appears to work!<br />

79 Risposte a “How to Prevent Toxoplasmosis”

  1. how do you test for this? how do you treat this if you have it? also is that 3/4 cup cooked spinach measured before or after cooking? it takes a LOT of raw spinach to make 3/4 cup of cooked spinach.

  2. This series is absolutely terrifying. I know that "to be warned is to be forearmed," but I also know thousands of cat owners are freaking out now! TFP.

  3. If 1/4 Americans are infected and it causes numerous problems, why don't companies and the government try hard to develop a cure? The parasite shouldn't be invincible… Have the scientists concluded that the parasites can never be removed?

  4. Listen, if you're not immune suppressed or pregnant, or thinking about getting pregnant, you really don't Need to be worried about this. Just practice good hygeine like hand washing.

    "and that r not fed raw meat"
    mehh not gonna happen with my cat, he likes dead dinos :)))
    from dry food even him got candida (dandruff, random excess weight, worse hair, dandruff, shackyness), no species is safe from starches!!! starches r nazis btw

  6. Uncooked beef, like (raw) filet americain is a problem. It can be infected too and is popular in Yerp. In France a lot of infection is assumed. However, if you freeze this meat to -19ºC for 48 hours, the parasite is said to croak, according to an RIVM study.

  7. Now that cats are villified in this matter is ridiculous. Millions of people have cats. Total hygiene and abstaining from meat raw or cooked should be highlighted. Dr Greger did not even mention blood transfusions and organ transplants as another reason which has been proven that it is on fact so.
    He mentioned that this virus cannot be detected in raw meat before its packaged and sold on the market. Billions of animals are slaughtered for food yearly therefore an obvious reason this virus will be sold in meat undetected. Lets include backstreet butchers and sales. I think this problem has still not been fully investigated only the tip of the ice berg has been revealed

  8. There was news in 2015 of a well-established hypertension drug, guanabenz, being effective at treating the latent cysts in mice (https://www.ncbi.nlm.nih.gov/pubmed/26303803), but there do not seem to be any human trials as yet. Could one be crowdfunded?* It would need to be possible to check the cysts have diminished in live humans. I do not know if brain scans can see them.

    *With the drug I guess being off-patent, it is very unlikely a pharmaceutical company will fund any such research. However, enough people are affected by this, that if some reasonable proportion of them chipped in, perhaps it could be done. Is there any way to crowdfund such research and feel empowered vs waiting in hope that something comes up? A pharmaceutical company would ideally develop a drug that does not cure the problem, but helps contain it, providing you keep taking the medication.

  9. Can we just get a video where you mention what can be done to ELIMINATE/KILL the parasite if you're already infected?! These cliffhangers are brutal! Thanks.

  10. Thank you Dr. Greger I'll make sure we put our cats out for adoption. All this is so informative!

  11. Wait, but can you please cover if there's ANY available treatment? My sister developed schizoaffective, I'm at high risk (two people in immediate family with schizophrenia/schizoaffective), and there's a strong chance we could have toxoplasmosis from having outdoor cats all our lives. You said in a previous video that common anti-parasitics don't work on toxo, so are there ANY treatments? Please help, Dr. Greger!

  12. Just wow. I've been speculating about this for years. In Germany parasites are taken far more seriously. All my suspicions have been validated.

  13. No wonder the US uses folic acid in processed wheat, it reduces intelligence in the population by blocking real folate uptake from food.

  14. Well, Neurologist know that you replace the toxo line for a variety of cerebral lesions and you ger the same curve of psyquiatric and cognitive decline as with toxoplasmosis. The dopamine and folate story is no more than a tale. There are better reasons to take good care of cats and to eat vegetables than this story.

  15. Why do Americans use inaccurate, arbitrary, and impractical volumetric units of food measurement? Everything should be grams. If possible raw grams and cooked grams to be clear.
    Not super related to this video, but in general this triggers me.

  16. I feel like the info about stray cat infection rates was mis-characterized. The text of the paper seems to indicate that 6% were actively shedding during the study. I believe that leaves open the possibility that literally ALL the stray cats studied were infected.

  17. Hi! Neighbourhood cats about 6+ come to my baclyard and poop all over and in the front yard. How do i sterilize the soil after them? Can I pour diluted bleach on the spot? What proportions? Thanks

  18. Also when I go to restaurants they ask if I want pork cooked?!?!??! Is it insanity? Do people not know??? Beef it’s what I thought it would be ok to have it not well done, but pork or veal?!?!
