Flashback Friday: Four Nuts Once a Month

Flashback Friday: Four Nuts Once a Month

“Four Nuts Once a Month” This is one of the craziest
articles I saw all year. A single consumption of high
amounts of brazil nuts improves the cholesterol levels
of healthy volunteers. OK, that’s interesting. They gave 10 men and women a single
meal containing 0, 1, 4, or 8 brazil nuts, and found that the ingestion of
just that single serving almost immediately improved
cholesterol levels. LDL, so-called “bad” cholesterol levels in
the blood were significantly lower starting just 9 hours after
the ingestion of nuts, and by no insignificant amount,
nearly 20 points within a day. Even drugs don’t
work that fast! It takes statins like 4 days
to have a significant effect. But that’s not even
the crazy part. They went back and measured
their cholesterol 5 days later, and then 30 days later. Now keep in mind they weren’t
eating brazil nuts this whole time. They had just that single
serving a month before and their cholesterol was
still down 30 days later! It went down and stayed down,
after eating just four nuts… That’s nuts! And no, the study was not funded
by the brazil nut industry. Interestingly, 4 nuts actually seemed
to work faster than the 8 nuts to lower bad cholesterol
and boost good cholesterol. These results suggest
that eating just 4 nuts might be enough to improve
the levels of LDL and HDL for up to 30 days,
and maybe longer— they didn’t even
test past 30. Now normally, when a study comes
out in the medical literature showing some too-good-to-be-true
result like this you want to wait to see the results
replicated before you change
your clinical practice, before you recommend something
to your patients, particularly when the study is
done on only 10 people, and especially when the findings are literally
just too incredible to be believed. But when the intervention is cheap,
easy, harmless, and healthy— eating 4 brazil nuts a month— then in my opinion, the burden
of proof is kind of reversed. I think the reasonable default position
is to do it until proven otherwise. So now every month I
eat 4 brazil nuts. In conclusion, a single
serving is sufficient without producing liver
or kidney toxicity. I should hope not! But what they’re referring to is the
high selenium content of brazil nuts, so high that 4 eaten every day
might actually bump up against the tolerable daily
limit for selenium. But not something we have to worry about
it we’re just eating 4 once a month.

  1. I believe it is actually selenium working magic. Look into other foods and supplements with selenium and they will help in the same way. Statin medication is dangerous and never actually seen good results without negative results.

  2. Hey Dr greger, are there any kinda of foods or diets that work for hair health and hair loss in both men and women? Thanks!

  3. I eat way too many Brazil nuts, up to a couple dozen/day, & eat them daily when available, which is about half the time. Brazil nut butter is delicious too! Also, I supplement w/selenium 200-400mcg/day. I have experienced no listed side effects of too much selenium. I believe since it kills cancer and supports mental health, it has been put on the list of "bad" healthy things, like B17/bitter apricot seeds, etc.
    Competition for the drug$!

  4. @drpetrabracht, a German Doctor, recommends 2-3 per day for her Hashimoto patients. The LDL effect is something very new to me. I think we should only take organic nuts. Thanks for these information. I like your book how not to die 🌱🤗

  5. I found a nice thing for helping blood pressure that worked well on me.

    2-3 large cloves of crushed garlic.
    1 teaspoon of honey.
    1 teaspoon of balsamic or apple cider vinegar (I haven't tried apple cider vinegar though).
    1 teaspoon lemon juice.
    1 teaspoon crushed ginger.
    Mix well.

    Put in a jar in the fridge for about 3 days.
    Take 1-2 teaspoons (5ml-10ml) with 300ml of water in the morning, about 20 minutes before breakfast.
    Note, if you are on blood pressure meds, check your blood pressure doesn't get to low.

  6. Brazil nuts are worth their weight in gold. I buy a bag of organic nuts (keep them in the fridge) and eat two a few times a week to get selenium naturally and to keep cholesterol in check. Don’t eat more than a couple a day. Brazil nuts are very high in selenium.

  7. The reason why this works is lots of people are deficient in selenium. Having adequate selenium will reduce cholesterol. That’s why the effect lasts

  8. I just bought your book, Dr Greger, and showed it to my friend and now she's also bought the book and the audible version. Also showing it to my family. Many thanks!!

  9. American Pharmaceutical companies having a heart attack as they watch this video.

    You mean someone doesn't have to pay $500 for a cholesterol drug??? What????

  10. How hard to test this again? Seems like it would be an easy thing for students to see if they can reproduce the results. Someone please put it to the test – and publish!

  11. These studies never mention other factors that might be involved like what ELSE were the people in the study eating or not eating during that time frame which could have had a HUGE impact on the results? I'm not discounting the fact that Brazil nuts don't have redeeming qualities, I'm just suggesting that for results to be THAT dramatic, other factors probably came into play.

  12. The drop in LDL-C was probably caused by the selenium. It doesn't follow that other nuts will have the same effect.

  13. This has to be the most useless video ever made by this channel! Must be running out of useful information so this is what you present?

  14. I wish these nut studies would specify whether the nuts were raw or roasted, and what difference it makes whether they are or not.

  15. Selenium Conten varies widely though. Brazil nuts are even grown in china. I believe only those from Bolivia have high amounts of selenium (in general) ….. but even then, selenium content most probably also varies from nut to nut

  16. I wonder about the very high methionine content of Brazil nuts, though, which should result in elevated TMAO levels and higher homocysteine in the blood. Since this is an independent risk factor for cardiovascular disease, it may attenuate the benefits of lower LDL.

  17. I have One Brazil Nut a day for selenium too protect from cancer however overdosing on Selenium can cause cancer. My cholesterol is A ok.

  18. I've been eating one nut every Sunday for several years now. I consider it my Sunday treat because is so delicious. Not sure if one a week is as healthful as 4 once a month!

  19. This IS nuts, ha-ha! I was wondering about the selenium toxicity, per a previous video topic from NF, so thanks for addressing this!

  20. If the volunteers were already healthy at the start of the study, then doesn't that mean that their serum lipid levels were already ideal at baseline? And would this work at all on people with hyperlipidemia?

  21. I don't know about you other guys, but I'm definitely getting more than four nuts a month. Have you seen how hot my girlfriend is?

  22. I guess the next Flashback Friday should be on eating 4 head of broccoli a month. This is funny.. Money spent about studying people eating 4 nuts a month.. 4 nuts a month….. How, why? Next study money should be spent on how people do on 3 nuts a day and 5 nuts a day.. Let's see.. We might see a difference.

  23. Sorry to ask in a video not really related..
    I have found myself eating more and more dandelion leafs. They are readily available when I'm out working on the fields.
    Have aquired a taste for their bitterness and can eat 100+ leafs a day.
    Ofcouse, leafy greens are healthy, but how can I know what leafs are good for me, and which I should eat fewer of?
    Gorillas seem to know this by heart, and I imagine that prehistorical humans also just knew, watching adults eat certain plants from young age… But me as a modern person is really cluelsss.. 🙁

  24. With all due respect, I gotta say, as a scientist, what you say regarding the burden of proof, really made me cringe
