Four Brazil Nuts Once a Month…

Four Nuts Once a Month

One of the craziest studies I read all year involved feeding people a single serving of Brazil nuts to see what it would do to the cholesterol levels of healthy volunteers. They gave ten men and women a single meal containing zero, one, four, or eight 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, was significantly lower starting just nine 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 around four days to have a significant effect.

But that’s not even the crazy part.

The researchers went back and measured their cholesterol five days later, and then 30 days later. Now, keep in mind they weren’t eating Brazil nuts this whole time. They just had that single serving of Brazil nuts 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, four nuts actually seemed to work faster than the eight nuts to lower bad cholesterol and boost good cholesterol. These results suggest that eating just four nuts might be enough to improve the levels of LDL and HDL for up to 30 days, and maybe longer—they didn’t 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 ten 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 four 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.

They concluded a single serving was sufficient “without producing liver and kidney toxicity.” What they’re referring to is the high selenium content of Brazil nuts—so high that four eaten every day may actually bump us up against the tolerable daily limit for selenium, but not something we have to worry about if we’re just eating four once a month.

I’d be curious to hear if anyone experiences similar results. Even if the study was just a fluke, Nuts May Help Prevent Death by improving the function of our arteries (Walnuts and Artery Function) and fighting cancer (Which Nut Fights Cancer?) and inflammation (Fighting Inflammation in a Nut Shell).

Even eating nuts every day does not appear to result in expected weight gain (Nuts and Obesity: The Weight of Evidence), so enjoy!

In health,

    This is an amazing finding. But I noticed that besides being high in selenium, Brazil nuts are also high in methionine, about the same as in chicken and some fish (1 g per 100 g). And in an earlier NutritionFacts video, methionine restriction is recommended for reducing cancer risk. So since food is a package deal, I’m wondering whether the benefits outweigh the risks for eating Brazil nuts. Has anyone else looked at Brazil nuts from this perspective? Please chime in with your opinions. Here are some links to support the above statements:

    This is an amazing finding. But I notice that besides being high in selenium, Brazil nuts are also high in methionine, in the same range as chicken and some fish (1 g per 100 g). And from a previous NutritionFacts video, methionine restriction is recommended to reduce the risk of cancer. I’m wondering if the benefits of eating Brazil nuts outweigh the risks? Has anyone else looked at Brazil nuts from this perspective? Perhaps the amount of methionine in 4 nuts per month is negligible? And another question is: which is better for the cholesterol effect, 1 nut per week or 4 nuts at one meal once per month? Here are some related links:

    • mixis

      The amino acid profile of Brazil nuts is not that important because they are very dense in energy. Further, there should be a higher demand for methionine on a plant based due to creatine synthesis, IMHO.

    • Robert Lee

      The methionine densities are similar, but based on an average serving size of 150g for a typical chicken breast and approximately 16g for 4 brazil nuts:

      Chicken breast 150g x 1g/100g = 1.5g methionine
      Brazil nut 4 x 4g x 1g/100g = 0.16g methionine

      I.e., over 9 times more methionine from chicken, based on serving size.

    • Thanks for your question! I am a Registered Dietitian and I one of the Moderators at NF.

      That is indeed true, Brazil nuts are high in methionine, unfortunately, I could not find any study examining methionine restriction specifically from brazil nut consumption and cancer risk or longevity. This study found that daily methionine requirements for a healthy person is of 15m/kg/day (i.e. a person weighing 70kg would require 1050mg per day, which is approximately the equivalent of one brazil nut a day). However, we should take into account that if a person is following a plant based diet, it is likely that the overall intake of methionine from diet is already low (1). Plus, it is possible that vegetarians and vegans require higher levels of methionine for creatine synthesis, since they cannot obtain it from diet (2). In my opinion, taking into account the health benefits of nuts, one should consume them on regular basis.

      When it comes how you many Brazil nuts you should take, in the study mentioned by Dr Greger, the participants took either 5, 20 or 50g or Brazil nuts in a single meal and did not consume anymore Brazil nuts for the following 30 days. An important detail about this study is that participants were told to exclude selenium rich foods in the day they took Brazil nuts (eggs, egg yolks, garlic, whole wheat cereal, viscera, etc.) because these nuts are quite a rich source of this mineral. Therefore, I suggest perhaps follow a similar protocol.

      Hope this answer helps!

  • RickSlade

    Turmeric coated Brazil Nuts! I’d make a fortune!

  • fencepost

    I tested this 4 Brazil nuts idea on myself when Dr. Greger first published this research and it did not appear to move my cholesterol either way. I am still hunting for the key to get my TC under 150. Also, 1/4 tsp/day of amla did not lower my TC either.

    • fwalker8

      I haven’t tried amla, but I found the four Brazil nuts didn’t seem to change my cholesterol. What did make a difference was having a handful of walnuts daily with my salad, and also eating at least a cup of beans each day.

      • Thea

        fwalker8: My 2 cents is that the key part of your experience is not necessarily that you did walnuts and beans, but that you used multiple angles at once. I think for people really struggling with their cholesterol, doing just one change like say adding amla or just doing 4 nuts, may not cut it. One of the reasons I like the NutritionFacts topic page for Cholesterol is that the last paragraph lists all the foods that have been shown to specifically lower cholesterol so that someone who is having a tough time could use multiple strategies at once.

        Thanks for sharing your story. I found it helpful.

    • 2tsaybow

      Are you eating a lot of beans? Isn’t it the soluble and insoluble fiber in them that helps pull cholesterol out of your system? It certainly worked to reduce my weight. I eat them three times a day at a minimum.

      • fencepost

        I eat WFPB (no added oils), including a lot of beans/lentils and some walnuts. Since I ingest no cholesterol, all that I have is internally produced. My current hypothesis is that there is a reason my body is producing so much cholesterol, and if I can find and fix that reason then my cholesterol numbers will come down.

        • Thea

          fencepost: I recently made some suggestions for someone else on this very topic. If you are interested, here is revised version with more info that I had a couple days ago:
          I’m not an expert, but I have some ideas for you.

          1) Is your weight ideal? Someone who is overweight may have cholesterol problems just from that situation. I first learned this from Tom Goff who wrote: “There is an interesting article on being overweight and its effects on lipids like cholesterol. It is quite technical but it concludes: “diets low in saturated fat and cholesterol are less effective in the obese. The most effective way for obese people to normalize their blood lipids is to lose weight”. . It is therefore possible that your system and metabolic response to eating a healthy diet won’t result in optimal cholesterol numbers until you are in a healthy weight range.”

          A lot of people lose weight switching to a vegan diet, but not everyone losses any or all of the excess weight. I can give you some great advice for lowering your weight the healthy way if you are interested.

          2) Do you have genes that just keep you with extra high cholesterol? I believe it is called familial hypercholesterolemia. If you do have this situation and if your diet is mostly whole, low fat plant foods, then maybe you don’t need to worry about your cholesterol levels? I don’t know that we have any data on people who have been eating a low fat whole plant food diet for many years an yet their cholesterol is still too high. But I heard Dr. Klaper once say to not worry about it. He thinks that if you are eating the right diet, then you cholesterol won’t oxidize and you won’t get a heart attack. (Assuming I understood him correctly.) I don’t know if Dr. Klaper has hard data on this assertion, but it makes sense to me. I believe you can do tests to figure out what your genes are regarding familial hypercholesterolemia??

          3) Do you eat a lot of fatty plant food? I was listening to a lecture recently from Dr. Jim Bennie and he told a story about a patient who was vegan for a while, but who still had high cholesterol. It turns out that that person was eating multiple avocados a day. To be optimally healthy, I think you need to go low-fat, not just whole plant foods. So, moderate your intake of avocados and nuts and skip the oils (olive oil, coconut oil, cocoa butter, Natural Balance etc.)

          4) Were you eating a less than ideal diet for many years before becoming vegan? It seems (to my lay person’s brain), that some people’s bodies are all messed up after eating a bad diet for decades. So, my theory is that just switching to a vegan diet is not necessarily going to get your body to stop producing massive amounts of cholesterol. Or maybe your body produces more for a bit to compensate for the change in diet?

          Whether my theory is correct or not, it may be necessary to adopt a diet especially dedicated to lowering cholesterol. This would mean not only to the general basic diet that applies to most everyone: A low fat whole plant food diet. But also includes incorporating those foods which have been specifically shown to lower cholesterol. The last paragraph on the topic page for cholesterol on NutritionFacts includes this list of foods along with links to the details: (This page is well worth checking out anyway as a great summary of the information about cholesterol in general.)

          And then, if that doesn’t help, I like to refer people to Joseph’s excellent advice on what to do if you have tried everything and you still can’t lower your cholesterol: (Joseph was an RD who used to be part of the NutritionFacts staff)
          Hopefully some of those ideas will help.

          • fencepost

            Thank you for that long reply. (1) by BMI, weight is normal. Height is more than 2x waist circumference; (2) possibly…it is on my list to get an ultrasound of my carotid arteries and if they are clean to not worry about cholesterol, (3) I do not eat avocados but I do eat some walnuts, and (4) I’ve been WFPB for 10 years now and before that ate a healthier-than-average standard American diet.

            I just read Esselstyn’s book and we are looking into how our recipes line up with that and whether we should make changes.

            It is possible, for example, that I have accumulated excess iron reserves (I’m a man) and that is producing an extra oxidation load which is stimulating cholesterol production (cholesterol can serve as an antioxidant). There is an easy and low-risk way to test that idea, and maybe I will.

          • Thea

            Good luck!!!

          • Pam

            Hi Thea, I’d be interested in seeing your thoughts on “I can give you some great advice for lowering your weight the healthy way if you are interested” as mentioned in your post. I am an avid follower of Dr. Greger, this site, Joel Fuhrman and other “nutritionally enlightened” docs. I am a young relatively healthy active 63 year old woman but I need to lose about 40 pounds to be in an optimal range. I recently weaned myself off zantac (hiatal hernia) and am doing just fine by following healthy practical guidelines of eating a vegal diet, eating early in the evening, elevated wedge pillow, avoiding trigger foods and the occasional use of digestive enzymes. I have realized about a 5 pound weight loss since I got off the acid reducers – for some reason I often felt “artificially hungry” when taking them. I’d be happy to hear your thoughts.

          • Thea

            Pam: I’m glad you asked! (I can’t share all this info unless someone really wants it. It’s just too big. But I love to share this stuff.)
            The nice thing about your situation is that you already understand half the battle. I’m guessing from your post that you already understand about the importance of a whole plant food diet and have at least a sense of how to implement it. That’s half the learning curve. The other half is understanding the concept of calorie density and how to apply it to weight loss so that you don’t get hungry and you still get all the nutrients you need.
            Dr. Greger covers calorie density, but not in enough detail in my opinion for someone who wants to apply it for the first time. I believe that Doug Lisle is one of the experts in the Forks Over Knives documentary, and he gives a great ‘calorie density 101’ talk officially called: How To Lose Weight Without Losing Your Mind. I have watched the following talk from Doug Lisle several times and think very highly of it. And it’s free!!! And it’s entertaining!
            As good as Doug Lisle’s talk is, it pretty much just gives you a solid understanding of the concept, but not enough practical information in my opinion. For starting to get the practical information, I recommend a talk from Jeff Novick,Calorie Density: “How to Eat More, Weigh Less, and Live Longer,” which is no longer for sale. Argh! (I mention it just in case you can get your hands on a copy. Happily, there is a very good second best source for that information: an article that Jeff wrote that you can get here:
            Be sure to pay attention to the charts.
            Chef AJ tells people who want to lose weight to eat “left of the red line”, where I believe the red line is on a diagram of hers representing is 600 calories per pound. And “left of the red line” is all the whole plant foods which are below 600 calories per pound. The above article from Jeff Novick gives you a good sense of which foods are “left of the red line” by food category. But if you want to look up the calorie density of specific foods, you can find many foods on the following site: Most foods on that site have the option of choose an ‘ounce’ as a size. Then you can multiply by 16 to get the calories per pound.
            It would be perfectly respectable if you are one of those people who are just not interested in the theory. You just want to dive right in and want straight how-to information. If you would rather not think about any of that (or start with the theory and then move onto this step), I have one more suggestion that Dr. Greger also recommends in his book, How Not To Die. Consider going through the free program from PCRM (Physician’s Committee For Responsible Medicine) called 21 Day Kickstart. The program will “hold your hand” for 21 days, including meal plans, recipes, videos, inspirational messages, and a forum (moderated by a very respected RD) where you can ask questions.
            (Click the green “Register Now” button.)
            At the end of the program, you will have a very good practical knowledge about how to eat with healthy and “low” (normal for most people) calorie density.
            Another recommendation that Dr. Greger and I share is to get Jeff Novick’s Fast Food videos for tasty, affordable, fast and healthy calorie density recipes. Also, on-line and free is a YouTube series of recipes/cooking shows called something like Chef AJ and The Dietician. I know that Chef AJ will not steer you wrong in terms of weight loss and providing accurate nutrition information.
            How’s that for some tips? If you give these ideas a try, please report back and let us know how it went.

          • Vege-tater

            Thanks Thea, lots of helpful info for newbies, (which I’m not), but with familial hypercholesterolemia and obesity rampant in my family, I still need to find the elusive “magic” combo! Since going hard core WFPB I’ve tried everything I could, and even though I lost well over 150 lbs, I managed to gain a few back when I still had 40 or so to go! Even as a self conscious teen (many moons ago!) living on diet pills and not much else I could NOT get thin, and after having kids, I ballooned to huge. Cheap processed food high high in fat/oil contributed, but in our home, produce was always included, and red meat was rare unless it was venison from a neighbor. Never a fan of animal products (besides seafood) so eliminating them was not difficult, and since I’d had my gallbladder removed very young, cutting fat was another multilevel blessing, though difficult at first. Health improved dramatically, but this weight thing is wearing! I obviously avoid all fats and don’t even eat nuts or avocados or other calorie dense foods. My big “splurge” is a few drops of toasted sesame oil or mustard oil as a flavor on a (no oil) stir fry occasionally! Since I barely even use even canned beans, nothing “sneaks” in with anything processed! I know adding more raw food is a good idea, but don’t even have the choppers to enjoy that option. (Raw soups and green smoothies are great tho!)
            I wonder if from starving for years my already screwy metabolism thinks it has to store fat for “survival” or something, because even though I know counting calories isn’t necessary, I have just for perspective, and my caloric intake was consistently well below recommendations for my height and activity level. I’ve read a lot about de novo lipogenesis, and I’m convinced I must have had a relative that was a REAL pig! LOL!

          • Thea

            Vege-tater: You have an interesting case. (Congratulations?) As you know, I’m no expert. But for what it’s worth, here’s my 2 cents: I keep thinking that you hit the nail on the head when you talked about replacing *some of* your cooked food with raw food. But I also fully sympathize (re: feel it also!) with your comment about not finding that idea so appealing…
            The ideal situation for a complicated case like yours, in my opinion, would be to go to Dr. McDougall’s clinic or a place like that (TrueNorth is another great option I think) and let an expert take a crack at you. But I understand that that’s not in the budget until after you win the lottery. (Which I’m sure will be happening any day now. But in the meantime…)
            As just a shot in the dark idea for you: I wonder if you could combine all the teeny, tiny tweaks that Dr. Greger has presented regarding weight loss. Maybe over time, all those little ideas would pile up for you. As an example of what I’m thinking about: I was flipping around through the How Not To Die section yesterday and came across the section on vinegar. Dr. Greger talked about a study that showed vinegar helped people to lose weight.
            Here’s my point: I would not expect vinegar by itself to have a giant amount of effect in the real world on most people. And you may or may not already include vinegar in your daily diet. What I’m wondering is : if you found all those little NutritionFacts tips regarding weight loss and worked to tweak your diet (and exercise) to incorporate those ideas into your daily routine, *maybe* it would have the effect you are looking for. It’s just an idea. I hope you find something that works for you, because with all the work you have done to get yourself healthy, you deserve all the health possible!

          • Vege-tater

            Thanks, you are so kind! I guess I just have to keep experimenting, it’s just kind of frustrating to have changed everything and hear and see everyone else manage quite nicely without issues. Oh well, such is life, we all do what we gotta do! And you can bet WHEN I hit the lottery (pretty unlikely since I don’t buy them myself, but my proxy occasionally does) I am definitely going to go to a 10 day!

    • Jenya

      Were you eating plant based though? Just curious.

      • fencepost

        Yes, I had been eating WFPB for 9 years before trying the 4 Brazil nuts.


      That’s exactly why I don’t trust any of these studies unless they’re done on FAT FREE VEGANS or RURAL PEOPLES. A bad food for us FFV may be a beneficial food to a person eating the SAD diet because they are just replacing one bad food with a lesser “bad” food.
      This is EXACTLY why you cant trust these studies unless they fit the above parameters.

    The selenium content of Brazil nuts can vary greatly between individual nuts and geographical regions where they are grown. A single Brazil nut can contain anywhere from 10 mcg to 220 mcg of selenium! More from this interesting article:

    • guest

      VegGuy: Thank you for the article. I knew about the wide variability of Se in Brazil nuts but had never seen data this extensive as proof. I eat two Brazil nuts a day just for Se, not to lower cholesterol. Somedays, I guess, I get too much Se and other day too little, and hopefully my average daily consumption of Se is within the safe and effective range.

  • uma7

    Is it safe to take 1 a day?

    • Dr. Jen _NF Volunteer

      Great question!

      The recommended dietary intake of selenium is 55mcg for those 14 and older and the “tolerable upper limit” for intake is 400 mcg. Most brazil nuts average between 70-90 mcg/ nut although, as VegGuy mentioned, the range can be quite variable.

      To get a sense of other foods with selenium, one cup of cooked brown rice has 19mcg and one cup of banana has 2mcg. Bottom line: one nut a day is probably safe if you are on a WFPB diet. If you are eating a lot of tuna (92mcg/3 oz) or pan-fried beef liver (28mcg/3 oz) you may want to skip the nuts. ☺

    The statement, “… 1050mg per day, which is approximately the equivalent of one brazil nut a day” is not accurate. 100 grams of brazil nuts would provide that amount of methionine, but one brazil nut weighs around 4 to 5 grams.

  • guest

    This is unusual since the amount of Brazil nuts doesn’t follow a dose-dependent pattern in lowering cholesterol. Brazil nuts are high in saturated fat which normally raises cholesterol. Assuming that the high selenium is the cause of the cholesterol lowering effect, perhaps too many nuts reverses this effect because more that 4 a month provides more saturated fat than is tolerable in regard to cholesterol

  • guest

    This article reminds me of a lecture I heard a decade or two ago about a professor of geography who noticed that countries with high levels of selenium in their soil, such as Senegal, have low Aids and cancer rates. He also discovered other minerals that seem to lower cancer rates. See

  • Fidel

    Was eating 1/4 of a brazil nut daily and did get TC down to 123 but was also getting only 20% of calories from fat (4% saturated) and was keeping BMI at only 17.5 while eating an average of 1750 calories. Actually did eat added oils in the form of Earth Balance buttery spread and Mindful Mayo but only 1/2 teaspoon servings.
    It is said that, depending on APOE status, it might not be as easy for some to lower blood cholesterol with low-fat eating. It did work well for me, an APOE 3/4, consistent with the research.
    Another possibly worthwhile point is that what’s called the Cardio IQ panel revealed my TC at 123 while the regular cholesterol test showed it at 144. That’s a significant difference, so many here might already be where they want to be, not knowing it due to tests showing numbers to be higher than they actually are.

  • mbglife

    You might want to check this NF video by Dr G from 4 years ago which compares the stated shelf life of oils with actual tested findings. Of particular note is the perfect conditions under which the oils have to be kept, and that the date starts at bottling, not from when it’s first opened. Before I learned of the cancer risks for oils (see Dr McDougall on this topic) I used to buy organic olive oil from a local producer in northern California. He was very open and honest and his belief was that well kept olive oil, if stored optimally and unopened, would last 2 years in the bottle. But once opened, only two weeks (and that was also if kept optimally). I no longer eat anything with oil in it–full stop.

    I hope that helps.

    • Jenya

      Do you have more info on oils, how to store etc.? Not familiar with this and would love to learn more. Thanks!

      • mbglife

        I see that I forgot to put the link in my last post above, so I just went back and added it.

        As far as storing oil, Dr Greger discusses it in the video. Dark container (like the ceramic bottles some use) no air (the is a problem once it’s opened and the more the oil is moved by pouring the more air mixes with it causing oxidation, so the fastest it goes rancid), and store in a cool place (dr Greger says the fridge, but the organic olive oil grower/distributor said that it solidifies faster which is a different form of oxidation. I have no idea if that’s true). Dr MC so-cal has a long video on cancer on YouTube and at about the 10 or 15 min point he shows charts from test results showing how using any vegetable oil increases risk of cancer. And of course, coconut oil is solid at room temp so it’s a huge source of saturated fat. And the fact that the body makes all that it needs doesn’t mean we men huge amounts of it. By comparison, if the body turns things into sugar for energy it doesn’t mean missed of sugar is good for you.

        That’s pretty much what I know. I have longer eat oils. Of a dish has been prepared with it I skip it. I only have a small amount of nuts or seeds or avocado with veggies to get the nutrients absorbed. And that’s it fort me.

  • KK

    Whole wheat food like pasta can provide good amount of selenium. Mushrooms such as white/brown/shiitake can contain small amount of selenium.

  • Kartoffelmao

    Are you stupid? I have to ask, since you seem to have a severe lack of putting things into perspective. 1 brazil nut is around 5g and has 0.7g of protein. Thats 2.8g of protein in 4 brazil nuts. Thats 201.6mg…

    If you are so concerned with methionine, then just eat a low protein diet if you must.

  • Gio Argentati

    I’ve been eating one Brazil nut each day for years. Do you think that I am consuming too many Brazil nuts? If so, what would be the optimal number of Brazil nuts to eat each month?

  • Gabe

    You would have to consume about 25 brazil nuts to equal 100 grams, so your safe eating just four per month.

  • Holleywoodfarm

    Since reading DrGs book I eat 4 brazil nuts on the first of every month and then 2 a day for my selenium. It’s that too many?

    Is it possible high blood pressure might also be lowered or has that been tested before?

    I was eating four a day, but I stoped eating them because I couldn’t find fresh ones. I could only buy ones in a bag with the shells removed. They would often taste a bit mouldy, although I couldn’t see any mould on them. But I read that brazil nuts can contain the mould that is found in peanuts, which you only need a microscopic amount of everyday to destroy your liver over time. If only I could buy them with shells on all year around rather than just at Christmas. They do organic ones on Amazon, but they are too expensive for me.

      Been reading a lot of interesting articles about the unexpected success of animals in the exclusion zone around Chernobyl, and the hormesis concept. Not saying it applies, but something to ponder?

    This is my new favorite nutrition site! I have two brazil nuts a day (for my thyroid) with my rolled oats with quarter cup ground flax seed, tsp cinnamon and berries every morning. Top it off with a cuppa hot turmeric tea.
