Dear Mark: Are Peas and Green Beans Healthy?

By Mark Sisson
194 Comments

For today’s Dear Mark post, I’m going to hold off on doing a big roundup and instead focus on a single question that keeps appearing in my inbox: the suitability of green beans and peas in a Primal Blueprint eating plan. I regret not getting to it sooner, for I can imagine the Vibram-clad pausing in produce aisles across the world, looming over the bright green beans and agonizing over the antinutrient content of the admittedly tasty legumes, dipping their callused hands heavy with barbell stink into the display case full of sweet peas, letting the tiny green pearls cascade through their fingers like Maximus Decimus Meridius caressing the stalks of wheat in Gladiator and thinking of casseroles from days long past. Well, wonder no more. Today we dig in.

Are peas and green beans Primal?

Sue

Peas and green beans are, botanically speaking, legumes. And since I generally recommend against the consumption of legumes, it seems to follow that the consumption of peas and green beans is “not Primal.” But hold on. Peas and green beans eaten fresh – not dried – are young seeds picked when unripe. The type of legumes we’re wary of are dried beans – beans that are allowed to dry on the vine until they rattle in their pods. Green beans and fresh peas are picked before they dry. In fact, green beans and peas have been bred to be digestible, palatable, and easily cooked before maturation. No lab-coated genetic modification, just good old fashioned selective breeding – the stuff we’ve been doing for tens of thousands of years.

When you pop them into an online database, the nutritional profile of legumes is pretty decent. They’ve got more protein than grains, fewer antinutrients (and zero gluten!), and a decent amount of minerals. I’ve always advised against making legumes a significant part of your diet, mostly because far tastier and more nutrient dense foods exist out there, but I’ve never said they’re evil, either. I’d much rather you load up on soaked, well-prepared beans than hearthealthywholegrains.

Now, as for why I personally avoid legumes? They don’t agree with my digestive tract. Through years of intensive and occasional culinary dalliance with the legume, I’ve determined that when I eat them in just about any quantity – more than a few bites – I suffer the distinctively rumbling protestations of my gut. And I tend to listen to my gut. He’s pretty astute, and he imparts a lot of wisdom.

But why do I occasionally eat green beans and (less often) fresh (not dried) peas? Because they taste good, make an easy dish to prepare, and make my gut happy. I can, and often do, eat a side dish of green beans (and sometimes peas, though not as frequently) sauteed in butter and tossed with a half cup of bone broth that simultaneously steams the beans and reduces down with the butter to form a viscous sauce that coats the tongue. Add some fresh ground pepper and a half pinch of chunky unrefined sea salt and I’ve got myself a “side dish” that can almost make me forget about the “main dish.” Eating this never makes my stomach rumble (unless it’s out of anticipatory hunger) and it never negatively affects my digestion. By all (of my) subjective measures, green beans and peas are fairly benign.

By most objective measures I was able to dig up, green beans and peas are also quite benign:

  • The green pea lectin (pisum sativum agglutinin) is “much less toxic” than others, according to renowned legume opponent Dr. Loren Cordain’s research.
  • Phytate content of green beans and green peas, which isn’t that high to begin with, was greatly reduced by simple cooking (PDF): green beans dropped from 150 mg phytate per 100 g portion to 52 mg phytate; green peas dropped from 384 mg phytate to 158 mg phytate. Most of the phytic acid was retained in the cooking water, though, so if you’re trying to avoid phytates, discard the water.
  • I couldn’t find solid figures for phytohaemagglutinin (the primary bean lectin) content of green beans, but we do know that uncooked kidney beans are extremely dense with the stuff. We also know that eating uncooked kidney beans will make a person acutely ill from phytohaemagglutinin toxicity, but that eating uncooked green beans will not. I think it’s safe to assume that green beans are therefore pretty low in the lectin, and in any case, cooking at a temperature of 100 degrees C deactivates most of it (enough to make soaked kidney beans safe to eat).
  • Carbohydrate content of both green beans and fresh peas are lower than the dried varieties.

I often say that all food exists on a spectrum of suitability, with the classic example being dairy. Raw, grass-fed, fermented is best, followed by grass-fed, fermented, followed by grass-fed, followed by organic, fermented, followed by fermented, and so on. To malign an entire category of food with impunity and without regard for the subtleties that exist between individual foods within that category is foolish. Wheat is not rice (or oats), bologna is not leg of lamb, the honey-roasted peanut is not the raw macadamia nut, iceberg is not chard, corn oil is not red palm oil, and the green bean is not the kidney bean.

Now I’d like your take on the subject. How do you handle young legume upstarts? Do you yell at them to get off your lawn, or do you welcome them into your home and hearth for dinner? Let me know in the comment section!

Thanks Mark! I was wondering where green beans stood in the spectrum of foods. I’m doing research in Chile right now, where green beans are really popular. While I was shopping with a friend, she encouraged me to buy a bag of frozen green beans. I did, but they’ve been sitting in my freezer for two months because I thought they were just like other legumes and didn’t really take the time to look more into it. Now I know! I’ll pull them out soon and see if they agree with me.

Like someone long ago said, the not-so-good part about the Primal Blueprint is that people start fearing the food at some point – unless they hear “the orders from above”.

WildGrok

That sounds good to me. If I don’t know enough of an issue I usually rely on “above”. It is different when I do my own research, which may or not agree with above. Not a problem for me 🙂

Very true. In my opinion, a strict primal diet is a great idea for everyone for maybe a month to start, but after that I believe everyone should do some experimenting to find what they can tolerate. I feared carbs for a while, but after a little experimenting I found that a bit of a higher carb approach with potatoes and some white rice works great for me. But everyone is different. To me, being in tune with your body’s response to food is key 🙂

I promise you that is a people problem and not a primal blueprint problem. The word “sheeple” didn’t come from nowhere. It’s a good point though. I’ve been primal since 2001. What I tell people is “know your enemy”. Your enemies are: 1) CORN!!! Corn syrup, cornbread, corndogs, Doritos, etc. No single food source has done more damage to more people than corn 2) artificial _____ – You are real. If your food is artificial it will make you less than your ideal self in increasing increments. Your body will also struggle to process it and over sustained periods of… Read more »

I agree, those are great points–“know your enemy,” tune/listen to your body, and.. live!

Analysis is only beneficial until the moment that it becomes excessive with diminishing returns; a stress that can deter you from confidence in your lifestyle. There is value in persistence, but knowing what information you’re looking for and when to stop is important to prevent getting burnt out in the search for a perfected diet.

I really appreciate this reply. My primal nephew questions my choice of protein shake, which is yellow pea based and an anti-inflammatory formula. When I can’t eat raw – this is my convenience vs. the horror of horrors I used to grab on the way to work. Whey protein inflames my joints – as said above- it’s all about getting to know your body. I cut the “mass-murderers” out – am a new and revitalized me. I can continue my intake without feeling that doubt…

This is so strange!!! I went to outback steakhouse for the first time last night, forgoing the loaded baked potato for some seasonal veggies which included green peas in the pod. I stared at them for a full five minutes, contemplating the relative evils of legumes before I just left them on my plate. If they had just been regular ole’ peas out of the pod I probably would have eaten them without a thought…but the fact that the pod was there made me pause(are green pea pods primal? Are they even called green pea pods? I always called them… Read more »

I’ve always loved fresh green beans and never seem to give me issues. But staying away from the squishy, preservative-soaked, and metallic-tasting canned varieties of beans and peas is always for the best.

Well, canned beans are technically already soaked and you can always find then either in glass or BPA-free cans.

Del Monte green beans are the highest in BPA among canned goods, even higher than the progreso soups that increased BPA 1200%! http://www.consumerreports.org/cro/magazine-archive/december-2009/food/bpa/what-we-found/bisphenol-a-what-we-found.htm

Canned green beans used to be my standard “low carb side dish.” and, when fresh and in season, I’m sure they will make another appearance 🙂

Jesse

Do you know of a brand that does NOT have BPA that carries peas or green beans?

I know for coconut milk its best to go with native forest since they are bpa free but… what about peas and green beans?

Eden Foods (a 100%Organic brand) lines their cans with Ceramic–very cool company–in all ways.

There are some other Organic companies that do as well–look on the label, they’ll usually say ceramic-lined or BPA-free.

The one thing I haven’t stopped eating is green beans (I was never a pea fan). The main reason was the number of plants my man put in the garden this past summer. But I have no gut issues with the green beans. I can’t say that with any other bean. And they taste amazing sauteed in some butter or bacon fat! Good to know about the phytates after cooking!

All Brits love peas with mint. They even sell frozen peas with mint in Tesco’s.

Have been avoiding peas but eating green beans because they came in my CSA boxes. Anything I get in the CSA box I eat (carrots, sweet potatoes etc as well as the “good” veg).

I love the primal approach because it doesn’t advocate all or nothing.

This is great to know, I have been wondering if beans or peas were ok to eat. I kept thinking that anything I can eat straight off the vine or plant should be ok.

yes, especially peas WITH pods, like Snap Peas or Snow Peas–lowers glycemic index ’cause increased fiber. and the pods are juicy, tasty, nutritious.

I’ve read about peas but in the South we have many that aren’t mentioned in the books. And the English language often fails us with the name. Can ya’ll help? What about these fresh frozen types: Field Peas (often come “with snaps), Zipper Peas, Purple Hull Peas, Butter Peas, Crowder Peas, Blackeyed Peas? (I’ve found Field Peas give me flatulence.) These are some I easily find in the stores – Thanks!

Oooh, yes, green beans fried up in bacon fat! It’s a great way to just about guarantee the kids ask for thirds! And how EASY is it to take a bag of frozen green beans, dump them all into a cast-iron pan of bacon fat, and cook till done? VERY!

Hmmm, now I want some with supper….. 🙂

I have always loved green beans but I’ve only had them in butter or bacon fat. I gotta try the bone broth method-its making me drool just thinking about it.

I read somewhere that green beans and snow peas are healthier because they are still in the pod. (And something about them still being in the pod made them more vegetable than seed.) Of course, can’t find where I read it now but does anyone know if that’s true?

Coach Calorie

Green beans are great. I consider them a negative calorie food because it takes nearly as much energy or more to digest them than the energy they contain.

Primal Toad

How did you come about this theory? I’ve never thought about them like this… so I guess leafy greens would most definitely be a negative calorie food if you take the time to chew!

We eat fresh green beans in our primal home and have for over a year. We probably have them twice a month and experience no digestive problems, or any other problem as far as we know. We make them in broth and with the butter as Mark described and enjoy them quite a lot.

Sarah

There is no better treat in the world that the first tender green peas-in-the-pod in the summer. The local (awesome) hothouse does shelling peas – because they’re under glass they’re ready usually by the end of May or early June, about a month before anyone else (including my own garden). I always buy a big bag, and take them with me when I pick my daughter up at school. And I hand them out to all the kids and I tell you, you wouldn’t see that much excitement with jelly beans!!! Then when our peas are ready, my daughter loooves… Read more »

Green beans are a staple at my house. Raw, cooked, it doesn’t matter, they are all good. So are peas, although I don’t eat as many of them.

Green beans with butter, and garlic powder with diced onion added. Just about the only ‘veggie’ I can get my non-primal wife to eat.

katie
4 years 9 months ago

Frozen cut green beans a huge staple in my diet for an easy side dish to pair with meat. I usually saute with herbed butter and dijon mustard beef and sauerkraut. I never really considered them a legume in my mind so this was insightful to read, but I’ll definitely continue to eat them because they agree with my body very well.

Peggy The Primal Parent

I’ve heard this question a lot too because my daughter loves to eat green peas. People ask me if they’re really primal. I have always read that they’re not but that hasn’t stopped me from letting my daughter eat a little bit. Now, I might just let her eat more! Thanks for the info, Mark.

Isn’t it nice to have someone like Mark confirm what you are doing is ok? Not that I do everything that Mark says but I’ve always thought that peas, green beans and sugar snap peas are not as harmful as other legumes.

We don’t eat a lot of peas, but once in awhile, I will make them. I buy the giant bags of frozen gb’s from Trader Joes … perfect for winter, when we don’t have a lot of GOOD fresh produce here in Nebraska!

Green beans are certified by Robb Wolf as well – at least he put them on his Shopping List for Week 1 on his site. I enjoy mine with pastured butter and a steak. Not AS tasty as a sweet potato, but for variety and a different color on the plate, why not?

I grow snap peas and green beans in my garden. When your three-year-old twins plant, pick, cook and EAT all of their own garden “veggies”, you don’t get too picky about whether a green bean is optimal or not. You just say, “thank goodness” and let them eat it. The snap peas tend to be eaten sun warm and straight off the vine. Man is that good! I had figured since the pods were mostly vegetable matter and very little seed was actually being eaten that they were probably on the healthier end of the spectrum from dried beans.

What a coincidence. I just bought a 1 lb bag of fresh sugar snap peas for $2 yesterday. I ate half last night and I’m eating the other half tonight. This article couldn’t have come at a better time. Hell, even if the conclusion was negative, they’re so good I’d be eating them anyway. I love them because they’re low in fiber, and I’m trying to cut the fiber in my diet. More carrots, snap peas, zucchini and mushrooms. Less endive, kale, cabbage and other things that are starting to bind up my gut.

I’m learning to listen to my body and trust myself and not CW. Before primal I always made chili with out beans because my body really did not like them. Now I’m just fine tuning my ear for subtle signs of what my body likes and dislikes.

Green beans, skipping breakfast when I’m not hungry, dairy are fine. Wheat, rice, legumes, eating late at night; not fine!

Big thunk on the forehead, accompanied by a “DOH!”

For some reason I have never considered green beans to be legumes — the fact that all beans are legumes never actually connected in my brain. Perhaps it’s because they are low in calories and taste good.

I shall happily continue eating green beans — especially trying the sauté’ in butter and add some bone broth recipe. I shall continue to eat snow peas as well. I have never liked green peas.

My son was allergic to eggs and nuts for a long time so I had to find food for him to eat on the paleo diet. I did include the peas and beans in his diet and homemade hummus and peanut butter. However, now that he is healed we gave the hummus and peanut butter a kick in the butt.

I have a lot of paleo recipes since I had to be creative for 3 years of his life. You can see a collection of them on my website.

Alas, I am allergic to green beans so none for me! Like Mark mentioned they are legumes, which can cause allergic reactions for some. Strangely, I am not allergic to peanuts, which are in the same family, but I don’t eat them anyway.

Fresh peas every once and a while are OK… not my favorite though!

Well, since we’ve gone mostly primal, my 5 kids eat bowls of peas or green beans instead of bread, biscuits or potatoes with their meals. A good trade off, I think. And since these two items are their favorite “vegetables”, collectively, we’re sticking with them.

Thanks Mark. I knew that fresh legumes were fine but appreciate the full report.

In the forum, newbies often ask about green beans and peas. Some uniformed member always says green beans = legumes = no primal. I hope this post will reduce that some.

I frequently eat both green and traditionally soaked legumes, and do fine.

Fresh pea soup is much better – just cook in some chicken broth, puree with a stick blender. I add a dollop of yogurt or heavy cream sometimes before pureeing. Really good, fresh flavor. You can also use frozen peas for this. Add some chopped green herbs if you like – mint is particularly good.

For a quick-ish vegetable side, I prefer carrots or broccoli over green beans, but I probably eat them 1-3 times a week. My favorite way to eat them is oven roasted (http://www.howsweeteats.com/2010/10/roasted-green-bean-fries/). Oh so salty and crispy.

I tend to think that if you can eat something raw without it upsetting your digestive system then it’s probably OK to eat generally.
