10 Reasons to Avoid Eating Legumes [+ Infographic]

10 Reasons To Avoid Eating Legumes - Paleo Diet

Have you ever stopped to reflect on the ways that we talk about beans?

Take the most famous beans in history, for example…

Young Jack was on his way to town to sell his family’s only cow, when a stranger talked him into trading the cow for a handful of “magic” beans. When Jack got back home, his mother was so furious about having only the worthless beans, that she threw them out the window. (The rest of that story took a more fantastic twist, of course.)

And even today, you might off-handedly note that something isn’t worth a “hill of beans,” indicating that it’s practically worthless.

However, if you spend 2 minutes on Google right now, you can find hundreds of articles about the health virtues of beans. Many sites praise their nutritional value, their high-fiber content, their ability to help prevent cancer, and even the amount of protein you can get from legumes.

They’re such darlings in the vegetarian and vegan world that you might think beans actually lead to bags of gold, golden-egg-laying hens, and magical harps.

And yet, you’re Paleo. You avoid legumes at all costs. Are you missing out???

Btw, if you want to find out more about Paleo, check out this article on the Paleo diet here. And if you’re confused by what is and what isn’t Paleo, you can find a comprehensive list of Paleo foods here.

First of All, What is a Legume???

To over-generalize, a legumes is a bean, pea, lentil, or peanut.

To get a bit more specific, here’s a list of the most common legumes (check out this site if you want a really comprehensive list):

List of Legumes

black bean
Boston bean
chili bean
fava bean
field pea
frijole negro
green beans and peas (yes, these are Paleo – read this article for why they are Paleo)
kidney bean
lima bean
Mexican black bean
Mexican red bean
mung bean
pinto bean
red bean
small white bean
split peas
soy bean (read this article for soy specific issues)

Should You Eat Legumes?

Most Paleo folk steer clear of legumes, but do you really know why?

While I don’t think legumes are the worst thing you can eat – things like pizza, milkshakes, and donuts are far worse – but, here are 10 reasons why it’s still healthier to avoid legumes (please pin the infographic below).

10 Reasons To Avoid Legumes on a Paleo Diet Infographic
Proponents of legumes list nutritional values that are based almost entirely on the legume in its raw state, but once a legume is cooked, it loses much (though not all) of its nutritional value.

Legumes are often praised for being a great source of protein, and while they do contain a decent amount, they’re still nowhere near as good as most animal sources, particularly when you account for the quality of the protein.

Legumes are also often high in iron, magnesium, potassium, and calcium. Unfortunately, these are the primary minerals that don’t get absorbed due to high phytate levels (see #2 below).

The Takeaway is that legumes have some nutritional value, but they are not providing you anything that you can’t get more easily and better from other foods.

2. Legumes Contain Phytates

are legumes paleo
Phytates – for the most part – just prevent minerals in a particular food from being absorbed. They’re not stealing minerals out of your body.

Phytates are not a major concern on their own. But if you’re planning on eating beans or lentils as a large portion of your diet, then it’s worth knowing that you’re not actually absorbing a lot of the minerals. This is particularly important if you’re considering replacing meat and animal fat with legumes, since meat and animal fats are some of the most nutritious foods you can eat.

In addition, phytates also inhibit the functioning of certain enzymes that are critical to digestion, such as pepsin and amylase. This explained a bit more in point #4 below. For a really thorough discussion of phytates, see this Weston A. Price Foundation article.

3. Legumes Contain Lectins

paleo stomachLectins are a class of proteins that plants produce partially in order to protect themselves from predators. (You can read more about lectins here.) Some lectins (such as Wheat-Germ-Agglutinin – found primarily in wheat) are terrible and definitely cause problems.

The 2 main effects of lectins are that they cause “Leaky Gut” and they lead to increased inflammation in your gut.

Both of these things may not cause any immediate problems when you eat lectins, but they often lead long-term to all sorts of problems, such as not being able to properly absorb vitamins and minerals, food allergies, arthritis, and a variety of other issues. Here’s a post from Sarah Ballantyne that explains more.

Some of the most well-known lectins are Peanut Agglutinin, Phytohaemagglutinin, and Ricin, all of which are found in legumes such as peanuts, kidney beans, and castor beans.

(Take a look at our Paleo diet food list if you are surprised to find out that peanuts are legumes!)

Now, most lectins are deactivated by heat, meaning that when you cook these foods, most of the lectins become harmless. There are exceptions to this (including both Wheat Germ Agglutinin and Peanut Agglutinin), but this is one of the main reasons that lectins are not as big of a problem as some people make them out to be.

Still, it’s something to consider. In particular, if you have any existing gut issues (IBS, for instance) or any auto-immune conditions (like Crohns or Hashimotos), then lectins are probably going to be far more problematic for you.

4. Legumes are High in Protease Inhibitors

Proteases are enzymes that break down proteins. So Protease Inhibitors are molecules that stop proteases from doing their job.

In your body, because protease inhibitors keep proteins from being properly broken down and absorbed, your body starts producing too much of certain enzymes. When this happens, it can lead to all sorts of problems like Leaky Gut, chronic inflammation, and allergic reactions.

Soy is particularly bad about this, but most legumes are quite high in protease inhibitors.

5. Legumes Have Carbs and Can Stall Weight Loss

I don’t think that carbs are necessarily “bad” for you.

That said, many of us have damaged our bodies and our metabolisms through decades of eating crap and not moving around very much.

If you are such a person – particularly if you are overweight, or worse, have Diabetes – then carbs are probably not your friend the way that they might be for someone who is healthy and not metabolically damaged.

Legumes – although they have more protein and fiber than most highly processed junk food like potato chips or cookies, still have quite a few carbs.

This is probably one of the last reasons that most people should avoid legumes (after all, they’re not really doing very much for you to begin with), but if you need to lose weight or control your blood sugar, then cutting legumes out of your diet can help immensely.

6. Legumes Can Contain PhytoEstrogens

Phyto means “plant,” and you generally know what estrogen is. So it’s not too difficult to figure out what a phytoestrogen might be.

Phytoestrogens are not actually estrogen, but they act like estrogen. Inside your body, phytoestrogens bind to the same receptors that estrogen binds to, but phytoestrogens give a much weaker signal than estrogen. Because the signals are weak, your body will often over-produce estrogen, which will disrupt your entire hormonal system.

This can lead to a variety of problems, such as disrupted reproduction and infertility, bladder cancer, asthma, and increased incidence of Alzheimers.

7. Cans of Legumes Contain BPA

BPA is a chemcial found mostly in plastic. It is strongly associated with heart disease, prostate cancer, breast cancer, miscarriage, erectile dysfunction, and abnormal reproductive development in children.

Legumes don’t naturally have BPA, of course, but the lining of many cans contains BPA.

If you’re eating fresh legumes that haven’t been canned, then this isn’t a concern. Also, there are suggestions that BPA may not be so harmful actually (see Chris Kresser’s article here).

8. Legumes have some Protein and Fiber

This is not actually a reason to avoid legumes, but it’s important to know.

Legumes tend to have more protein and more fiber than most other plants. This is particularly important for vegetarians, since protein can be hard to come by. In addition, much of the fiber in beans is soluble, which promotes – rather than disrupts – gut health.

Like I said, there are some positive qualities to legumes.

However, if you’re not vegetarian, the argument for protein is a fairly weak one, since legumes pale in comparison to most animal sources of protein, both in amount and in quality.

In terms of fiber, legumes are a good source, but contrary to popular belief, fiber is not particularly vital to one’s health, and in any case, if you’re eating enough vegetables (and maybe some occasional fruits), you’re going to get your fiber.

9. Legumes Contain Saponins

Legumes are extremely high in saponins. Ok…but what the heck are saponins???

Saponins are compounds that are found in many plants, including most legumes. They have a particular chemical structure that allows them to bind to the surface of your intestinal cells.

Once saponins bind to your intestinal walls, they often cause the cells lining your intestines to either “open up” or else to die. In either case, the effect is a Leaky Gut.

Once that happens, saponins, bacteria, and other things start leaking into your bloodstream. An immediate effect is that saponins start destroying the cell membranes of your red blood cells (as well as leading to general inflammation in your body). After that, all sorts of other bad things start happening.

10. Legumes Contains FODMAPs

FODMAPs are a type of carbohydrates. They’re not a problem for everyone, but for many people, they cause a variety of digestive problems.

Pretty much all legumes contain Galactins, which are a particular type of FODMAP.

If you know or suspect that you have digestive issues like Irritable Bowel Syndrome, then legumes are one of the first things that you should cut out.

Here is a great post from Chris Kresser on FODMAPs, if you want to learn more.

Peanuts are Particularly Troublesome

Peanuts are terribly unhealthyPeanuts are a particularly bad type of legume, and are something that pretty much everyone should avoid.

There are 2 particular reasons for this:

1. Peanuts contain Peanut Agglutinin, which is one of the most problematic lectins. It’s not adequately broken down by heat, so it causes all of the digestive, inflammatory, and immune problems discussed above.

2. Secondly, peanuts (unless, perhaps you’re eating them within 10 minutes of picking them from the farm) usually contain Aflatoxins, which have been definitively linked to increased risks of cancer.

Soy is the Worst Kind of Legume

Avoid all soy and tofuIf there is any legume I’d avoid above all others, it would probably be soy (with peanuts being a close 2nd). There are a variety of reasons for this:

First, when you eat soy, you typically aren’t just eating the bean itself. Most of the time, you’re eating a processed form such as tofu or soy milk, where the toxins have been concentrated and amplified.

Because of this, soy products are a huge source of lectins, phytates, and particularly phtyoestrogens, which cause all sorts of hormonal problems.

For men, this can often lead to “man-boobs” and infertility, and for women, it can also mean infertility as well as menstrual problems, as well as a host of other problems, such as bladder cancer, asthma, and increased incidence of Alzheimers. (See this article for more studies and side effects.)

The impact on infants who are fed soy formulas can be even worse and more devastating.

Moreover, soy can also lead to faster brain deterioration. It’s unclear whether this effect is caused primarily by the phytoestrogens in soy or the fact that many people who eat a lot of soy don’t eat enough good sources of B-12, such as meat.

In addition to everything else, almost all of the soy in the US is GMO.

So Should You Eat Legumes??

paleo why beans are bad
Despite all of the possible negative effects that I’ve pointed out, I can’t really say that you should definitively avoid legumes. Aside from peanuts and soy, they’re typically better than grains, and if I were vegetarian, I’d almost certainly eat legumes in order to get more protein.

And yet, I can’t ever imagine recommending legumes as a nutritious part of a healthy diet. There is far too little to gain from eating beans versus the potential for digestive and hormonal side effects.

However, if you are going to eat legumes, then it makes sense to eat them the same way that humans have for about 10,000 years (by soaking and sprouting them). (Editorial note: I want to clarify that peas and green beans are Paleo even though they are legumes. This article explains why this is so.)

The process of soaking, sprouting, and/or fermenting can break down many of the lectins and phytates, and if you’re fermenting, you’ll also get some bacteria in there that is very good for your gut.

Personally, I tend to follow the lead of Jack’s mom and toss my beans out the window, hoping that something more magical will come of it. (Cheeky. But true.)

What I don’t understand about this whole idea is the promoting of eating animal flesh rather than a legume, which grows from the ground. Think of all of the harmful effects of eating any non-organic meat and/or dairy products. Here you are picking apart something that grows from the earth, when you could be elaborating on foods that really are horrible for your health – like all non-organic meats and dairy items.

John - February 15

LOL…… diet trends…. so dumb

yelloww2 - March 13

You might want to research protein and cancer, also with all the bad foods you shouldnt eat, beans arent likely on the top of the list

    jmhendon - March 14

    This is probably a useless reply, but let me know if you’d like to discuss any particular cancer research. I’ve read far too many papers on cancer and diet, and while you are correct that beans are nowhere near the top of the list (it’s something I point out in the article above already), my assumption (rightly or wrongly) is that your reference to “protein” is based on a vast misunderstanding of the research. One could make a good argument that the Prolamin class of proteins (found predominantly in grains) are one of the primary contributors to incidence of cancer, and I’d agree, although there are a variety of factors (excess energy intake, micronutrient deficiencies, imbalances of polyunsaturated fats, etc.) that appear to also play significant roles. Unfortunately, much of the reporting of the research has been shoddy at best, often focusing on things like casein – a protein that is linked in vitro and apart from whole foods to cancer but not in vivo or as part of whole foods like raw dairy.

yelloww2 - March 14

It’s not a useless reply and it amazes me that humans (as a whole) still haven’t figured out our ideal diet. This is a well written article and I don’t want to detract from the research you have put in but I recently read “the China Study” and felt that the Macro type approach to analyzing human diet to be more substantial than analyzing individual nutrients within a food. The China study’ evidence of animal based products and cancer are compelling and recently have me wondering if vegetarians had it right all along… I recently joined cross-fit and they push the Paleo diet there which I have been embracing for over two months and am still learning…

    jmhendon - March 15

    Thanks so much for the reply and the compliment. Very much appreciated. I try not to be dogmatic about very many things. I think that being a vegetarian can be fine and done well (I have a lot of vegetarian friends). However, just based on my own reading and his responses to critiques, I generally feel like T. Colin Campbell is not very nice and also intellectually dishonest in many ways. I think that Denise Minger’s critique ( is still the best. In the end, you’re still right, either way, about legumes. They most definitely are not at the top of the list of things to worry about.

neuruss - March 21

As usual, any idea converted in religion ends up converting idiots in fanatics.
I agree with most of the paleo diet principles, but I just can’t understand the banning of legumes, and all the reasons exposed sound lame to me, to say the least.

For every single food group, you will hear thousands of experts in favor and against.
Red meat is essential vs red meat in cancerous, egg is high in cloaks your arteries vs egg is good for you,etc, etc…

When Paleo enthusiasts spell their gospel, they usually talk about an hypothetical cave man called “Grok”, and how would he have eaten in those days,and its way of life, etc… meaning that if Grok did it that way, we should do it too, because we sharethe same genes!

Honestly, I just can’t imagine Grok saying to the starving tribe behind him “Watch out for those beans! They have lectins!!”.

    jmhendon - March 21


    Yours is an excellent point. Pre-agricultural humans who couldn’t find enough food to eat would definitely have eaten anything they found that didn’t cause them to become sick. Not to take away from your point, but with many legumes, although they didn’t know it, the lectins are exactly what would have made them think twice. Raw kidney beans, for instance, will make you incredibly sick.

    Legumes are certainly not the worst things you can eat, and many cultures ate them for thousands of years with no adverse consequences. If you’re going to do it, though, I’d highly recommend soaking overnight, which most people don’t do any longer.

    We shy away from talking about “Grok” because I don’t feel like it advances the discussion very much, although evolutionary biology is necessarily the beginning point of modern nutritional science.

    Also, just because you have people on both sides of an argument, doesn’t mean that one side isn’t wrong. I think you have a great point of view, but my thought would be that just because humans ate a food when they had nothing else to eat does not necessarily mean that it’s optimal. The converse of that is if humans ate a food for millions of years (veggies, meats, seafood, fruits), then the likelihood of harm is very low.

      neuruss - March 22

      I agree.One thing that makes me wonder (and I admit I don’t have an answer) is how much our “genes” are supposed to dictate what we should eat or not.
      2/3 of mankind is lactose intolerant, while most europeans and their descendants consume milk and derived products on a daily basis.
      Is it in our genes, or it’s our feeding habits that make us more tolerant to certain foods?
      Asians are known to be lactose intolerant (except mongols who have been raising horses and drinking their milk for ages).
      However, people of asian origin living in western countries eat exactly what we all eat, with no problem at all. How do we explain that?
      The same goes for amerindians. They are supposed to be lactose intolerant (same example).However, my country (Argentina) has a huge dairy culture and so far, nobody has died (as far as I know…), and there are a lot of people with amerindian genes. So how do we explain that?

      All this makes me believe that the argument about Grok’s genes has many weak points.

        jmhendon - March 22

        Relying solely on genetics does have various weak points, as you pointed out. For instance, when humans first came down from trees onto the savannas, they weren’t “evolved” to scavenge and eat the brains and marrow that they started eating. However, it was highly nutritious and was what permitted the development of larger brains.

        Lactose persistence is interesting because it’s barely a genetic change. The distinction is so minor genetically (to allow for production of lactase into adulthood) that it’s almost an epigenetic shift. The fact that many people of asian origin eat dairy does not mean that there is no problem. Lactose intolerance doesn’t typically cause severe issues, but rather bloating, gas, and mild inflammation. I think you’ll find that those symptoms are pretty common among asian folks who eat dairy.

        In the end, I agree with you that we shouldn’t base what we eat entirely on genetics, but I’d still contend that it’s a very good starting point. For instance, genetically, humans produce zonulin when they eat gluten, which then causes the tight junctions in our epithelial cells to open up, leading to leaky gut, inflammation, auto-immune conditions, etc. It’s a genetic condition of all humans. We don’t usually die off because of it, but it’s not good.

        Marcy - December 11

        I like that idea. I am tired of diets claiming superiority for everyone. Blanket ideas are for people that can’t think beyond that. I am 48 and until I meet someone else that looks younger and healthier than I do at the same age, I will continue to eat vegetarian. I eat my antioxidants, but more than diet, I think it’s the lack of hypocrisy in my diet that keeps me in my youth. I would say it’s genetics, but you should see the rest of my carnivore family.

moo - May 6

i suggest you goto look up pinto beans,to say fiber is not important,is very misinformed ,many cultures use beans if they cant,or dont have the means to eat meat.

    Jeremy - May 6

    I may have worded it too strongly to say that “fiber is not important.” What I would say is that fiber is important for much different reasons that mainstream nutrition has believed for a long time, and that fiber from beans is not necessary, since we get plenty of fiber from fruits, veggies, and even tubers. You shouldn’t rely quite so much on It’s a good site, but limited in its scope.

Anon - June 7

With the high cost of organic meat it makes more sense for some people to eat beans as opposed to the hormone/ antibiotic/corn fed animal flesh that’s cheaply available. As with everything moderation is key. Beans aren’t the only alternatives vegans use. There’s Chia seeds, quinoa, amaranth etc

    Jeremy - June 8

    Thanks so much for the comment. Like you, I wish that our animals were fed fewer antibiotics and grains. Hormones is an odd one – the meat humans used to eat (primarily of bulls) is MUCH higher in hormones than anything humans artificially inject today. However, in any case, most folks are still much better off eating the meat (even if not organic or grass-fed) than legumes, mostly just for the nutritional value. Beans, seeds, and things like quinoa are all fine, but they’re relatively low overall in micronutrients. I find that a lot of people – in the media in particular – simply resort to fear tactics to confuse us. And it’s unfortunate, because I’d much prefer to rely on the simple nutritional facts and scientific research.

Eric - June 11


What do you make of the fact that small red beans and red kidney beans ranked highest in antioxidant potency (and proanthocyanins) in a 2005 Department if Agriculture study?

    Jeremy - June 11

    I don’t know that I’ve seen the study, but I definitely think there are good qualities to legumes. And as I noted in the article, they’re far from the worst things to eat, particularly if they’re properly soaked. From a practical standpoint, I see many people do better without them, but many people also tolerate legumes well.

Jake - June 13

Everyday for lunch I eat a grilled chicken sandwhich and a TON of beans (different kind every day). I have been doing this for about 2 years now and my cholestrol and tryglicorides has came down tremendously and my blood work as A ok. Even my blood pressure has came down to a point where I don’t have to take medicine for it anymore. I still eat red meat for dinner and other vegetables like broccoli and green beans. Obviously the beans are helping.

    Jeremy - June 13


    I’m very glad that your diet and lifestyle are working well for you. If I were you, I’d be very resistant to changing something that I’d seen work well for a long time.

    However, it really doesn’t say anything about beans or legumes. You say “obviously the beans are helping”, but I’m not sure how you came to that conclusion. Just because beans are a part of the diet you’re eating doesn’t necessarily mean that they’re the part that’s helping. And more importantly, it’s dangerous to rely on just one experience (yours), which is why I try to provide the science and also a wider range of experiences. And in both (science and wider range of experiences), I’ve seen many people do much better without the legumes (even though I don’t believe they’re all that bad).


jenna - June 19

Just cook the legumes really well.
Beans and lentils, dried, soak minimum 8 hours with salt and kelp (seaweed)

Double boil with salt and kelp for example 4 hours and keep changing the water every 1-1 1/2 hours washing them to get rid of the nasties that cause bad absorption etc.

I eat a mainly organic raw plant based diet, which include occasional legumes, grains, eggs. I will only consider eating meat if it has been treated 100% humanely but because that is pretty hard to find I don’t eat much. I still don’t have a true understanding about fish yet, but I will eat it if it is sustainable. As for mercury levels I believe it has to do with where the animal is in the food chain, if they aren’t eating other fish containing mercury, example sardines, anchovies etc they will have lower mercury levels.

But really I don’t think we eat enough legumes anyway, I agree we need to focus more on over consumption, production and cruelty of the meat industries and the impact its having on the environment and our health than legumes.

    nick - September 12

    but if a food stuff requires soaking overnite and boiling for 2 hours…..maybe that´s a sign that it is not meant fo us? hi temp cooking for destroys the nutrients anyway!

anon - July 5

JENNA…..what do you mean when you say “double boil?”


Traci - July 8

I have always tried to eat healthy, lots of organic veggies, fruit, chicken and eggs once in a while. I can not eat red meat or fish. I eat various beans for protein, I typically don’t eat much dairy and have oatmeal every day. However, over the past few years my vitamin levels continue to be in the low range, it was like I was not absorbing any nutrients! I recently learned that I have osteoporosis (too young to have it) I constantly felt sore and I repeatedly got canker sores in my mouth. I would wake up feeling weak and old. I did what most of us do and started researching online… Which lead me to this article. It makes so much sense. I have cut out all gluten, all legumes added more fresh fruits, veggies, nuts and chicken. Some could say it is psycho semantic, but I am starting to feel a little better day by day.
Thank you for the great information!

    Hussein - July 19

    How do you cook your beans and what kind of beans have you been using?

Mr J - July 26

Thank you for producing this interest provoking article, I’m an advocate of the paleo concept of evolutionary eating patterns and regard the science to be very compelling.

I have been wrestling with a few research contradictions in regards to the legumes debate and would be interested in your thoughts.

1. An evaluation of the definition of health may boil down in simplistic terms to a psychological definition of happiness and a physiological output of longevity. Although their are many variants that make up the two including genetic theories, I became very interested in a blue zones project which looked for communities across the world with much higher concentrations of centurions.

To cut a long story short, 5 completely different communities of very healthy, low disease level, long living people had very similar lifestyle traits.

They all ate limited amounts of meat (5xper month) and mainly ate plant plant based proteins/ legumes ( probably all cooked in the way you mentioned)?? Is that just genetic or a very strong lifestyle characteristic.

They also had a trait of doing very slow long duration cardio which is pretty much the opposite of what is recommended now as we confuse fat loss with health.

Another issue I have is with modern scientific research. Very little is researched without a monetary motive as it costs so much to research something in the first place. The amount of money made from advising people to increase their protein intake to medium/ high levels is astronomical which has made me question as a health professional what is really true, or what is motive driven data. With this in mind and the added component that lifestyle research is so hard to execute due the substantial variables It is hard to rely on many avenues of scientific data without a deep questioning of the validity of the testing and the motives. I know from experience that scientific peer reviews of literature can be shoddy at best and are more about the prestige of the volume of publications a scientist has to his name, rather than the quality. This is a highly debatable area that is very sad and frustrating as what we’d all like to see is transparent, unbiased data that reflects a truly probable outcome.

Lastly, my thoughts turn to sustainability. The economic issues of our time along with drain of our natural energy resources means that we’re literally destroying the the planet. I like to project an idea, concept or philosophy that is open to the benefit of all mankind and I’m questioning whether meat production fits well into this equation.

What do you think about the global sustainability of everyone on earth following a paleo diet? Would it at all be possible? Would the manufacturing/ecological costs be too damaging to the global resources of the planet? Would we all have to become farmers to eat organic produce at this volume?

Thanks for reading my thoughts. I’ve found that in my many years as health professional and student that is best to not rest and follow a theory in isolation as science is there not to give a right answer but an answer that is the best at the time until more research is done.

In other words, keep an open mind and always stay a student.

    Ancestral Chef - July 26

    Hi – I do think that legumes can be very healthy if prepared and cooked well. However, that doesn’t mean there are more nutritious foods out there (like organ meats, fish, shellfish), especially when measuring micronutrient content.

    I share your concerns about modern scientific research having been a scientist and growing up in a household full of scientists.

    Regarding sustainability – I’ve heard a few good talks on this issue, but I haven’t seen many great articles about it yet (I’ll let you know after I search more!). Here’s one by Robb that touches some of the issues:

      Mr J - July 27

      Thank you for your reply Ancestral chef. Firstly, I’d like to point out that I have no emotional attachment to either paleo, vegan or any other food preference but I do have a passion for health. I personally follow many of the paleo concepts to a lesser degree but also incorporate other vegetarian style methods.

      As a nutritional scientist you are much better placed to inform on the micro- nutrient comparison Vs absorption argument than I am and I’m sure we could reside back to the scientific data validity argument again and again.

      I suspect you could possibly separate micro nutrient comparisons from an individuals nutrition absorption ability, genetics, environment, lifestyle, food timing, hormonal balance, water quality, food combinations etc etc.

      The variables could be vastly complex and override a paper based like for like food micro- nutrient comparison.

      Thank you for the sustainability article, there are many arguments that can swing both ways in the predictions of global economies vs the paleo/ vegan arguments.

      What we can all agree on is that there are some major issues in food production with centralised, corporate, money driven farming taking president over local farming.

      Standards of living have been improving but so has social inequality. Example: the 85 richest people in the world have more money than half of the worlds population of over 3.5 billion people. 1.2 billion people go hungry every single day. We have more slavery today than we had 100 years ago.

      In the current system, GDP goes up when peoples health goes down. More cancer, more money. People having more material stuff hasn’t translated into health and happiness but has actually done the opposite.

      As we stand today under the dis functional system we endure, I see paleo as a middle class dietary option which has interesting and logical, health potential. The cost for my family of five to eat paleo is therefore quite considerable.

      This then brings me back to my question about the definition of health.

      Will paleo help me live longer?
      Will paleo help me live happier?
      Is paleo scientifically sustainable right now/ and will it be so in an improved social system?

      Short term physical improvements in health and performance can also be detrimental in the long term. Example: creatine will improve your strength and endurance but can damage your internal organs long term. What makes the car run better now may run the tyres down quicker in the future.

      Who knows? Very difficult.

      Ps. In regards to future reading for yourself, I have found the Zeitgeist movement literature to be an extremely interesting resource of information regarding health, economics and sustainability. Worth a read.

      I also found literature on sustainable insect protein to be very interesting as a future option as well.

My take away here is that if you have GERD or digestive issues, not eating legumes would be better for you. Should you never, ever eat legumes? In my opinion, the article didn’t say that.

Well, if heat destroys most nutrients in legumes then it does the same with meats!! Obviously! Animal products are the most contaminated foods and difficult to digest….if we are natural meat eaters we wouldn´t need to cook meat….we would lap down the blood straight after the kill…just like natural carnivores do.

And I´m no fan of legumes….if it needs to be boiled 2 hours then it probably ain´t meant for humans! Try eating them raw! (peanuts not inc)

    I have tried vegetarian and vegan diets and eating legumes gives me horrible acid reflux. I really wanted to become a vegan but my body just doesn’t like it. I also have issues with resistant starch. Everyone’s body is different. I eat lots of veggies, some fruits, nuts, seeds, chicken, fish.

    There is no perfect diet for everyone.

Hard enough to give up sugar and bread, now beans too? The paleo diet advocates all talk about the “healthy” paleo man eating meats and vegetables. What about the fact that life expectancy was below 50 years?! I agree the modern diet leaves much to be desired in the way of nutrition, but we definitely need to get up and get moving as a society.

    Hi Meg – much of that increased life expectancy is due to modern medicine (like pace makers, the fact that breaking your arm doesn’t lead to death, better child mortality rates) rather than our “improved diets.” And I completely agree with you that moving more is fantastic and something we all need to do more of.

    As for giving up more foods – that can be one way of viewing things, that you’re giving up freedoms you once had. But really (especially for sugar and bread) you’re giving up vices so that you can live a life free from illness and free from addiction to a food. If you view it in the positive, it’s much easier.

Cashews aren’t legumes.

    Thanks for spotting that Tina – I thought I had edited that error out before, but it must have been in a different post. Deleted now. Cashews are a fruit.
