Uncooked kidney beans... toxic!

    So yesterday I learned the hard way that a mere 3-5 kidney beans (uncooked) contained enough phytohaemaglutanin to cause nausea and whole bunch of other symptoms. OMG. Worst morning in a long time.

    I didn't know they had toxins in them (kidney beans being the worst of the beans).... but I drank around 18 beans in a smoothie (just to try a new ingredient). An hour later, I was feeling awfully nauseated and got progressively worse.

    I had a class to teach at 9:45A, but at around 9:30 I was feeling REALLY bad so I did a Google search on kidney beans to discover that I had ingested this poisonous toxin. Symptoms: I would vomit, have stomach aches, waves of diarrhea, dizziness, among other symptoms. Ugh. I knew my class was going to require me to be a bit more active and that there was no way I could teach without throwing up during it, so I decided to induce vomiting.

    Long story short, cancelled class, ended up at the hospital. Dealt with an incompetent doctor, OMG, SO incredibly incompetent. He ignored my explanation regarding what I ate and was treating me like I had a digestive disorder. WTF?!

    The effects of the toxin wore off after about 5-6 hours. THANK GOD. Otherwise I think due to the incompetency of the doctor, I would have been dead if the toxin was left in my system at life-threatening levels.

    Anyway, lesson learned: BOIL your kidney beans well. And thank God for the Internet. The induction of vomitting I think saved me from it being a lot worse.

    I read about that last year sometime, I had no idea that red kidney beans contained that before then. Glad that you're safe, hope you feel better soon.

    I thought this was going to be a thread about toxic farts.

    The name itself makes the food seem unappealing, but, that is some scary shit. WTF, good to know, glad you are alive, killed by kidney beans isn't the way to go.

    Interesting piece of info. Wonder if it belongs in the kitchen grimoire.

    Turbo, you can buy dried kidney --and other-- beans in any grocery store, but you usually soak and then boil them before eating. I must have eaten my weight in kidney bean salad as a kid. Still love it with boiled eggs, chopped onions, pickles and some mayo so they obviously are fine if you cook 'em.

    Always boil them before putting them in a slow cooker, as the temperatures never get high enough to kill the toxins.

    And this is why raw foods diets aren't all they're cracked up to be.

    raw food diets don't propose eating poison. even kids know raw beans are for sticking up your nose, not for eating.

    Wow, terra, thanks for posting. Sorry you had to learn it through experience. I had no idea.

    Can you explain exactly what you did? did you not boil them long enough? did you buy them in a can or prepared?

    I just didn't cook the dried beans. I don't usually eat beans, nor do I have cooking experience with beans. All I knew was what I read regarding the wonderful health benefits of kidney beans, which was all very glowing and positive. I never came across any toxic info. I had purchased a bag of beans the day before and added some to my "veggie" smoothie for the added nutritional benefit.

    Anyway, the toxin affects cell metabolism and causes red blood cells to clump together. It also affects protein transport through the cell membranes and induces mitosis (cell division). Reading this description seriously FREAKED ME OUT. I was like... I need to throw up NOW. icon_eek.gif

    On the bright side, I got a nice digestive cleanse. icon_confused.gif

    ECnAZ, he was consuming the dry, uncooked beans you get in a bag, not canned ones, which are cooked. You can eat the canned ones right out of the can and they are fine, except for the possibility of farts.

    Guys, I am soooo confused and I'm trying not to sound like an ass here. But, who would ever think that dried beans or any kind, are edible? Dried beans are about as hard as stone, like a bag full of pebbles. I couldn't even imagine thinking that my body could digest them unless they were cooked.

    Don't get me wrong. I am unbelievably sorry for Terra that he went thorugh what he did and am grateful that it didn't turn out worse.

    MuchMoreThanMuscle said^ Well, he probably thought that after throwing them in the blender to mix them into his beverage that things would have been fine.

    It's not that hard to assume that this could be a possibility. We do this with nuts and peanuts (which are also technically a legume just like beans but simply much higher in fat content). The only reason they (true nuts) turn into a creamy texture is because of their higher fat content after blending them in a blender.


    I guess. But, using the nut comparison, thinking the dried bean would be okay would be like putting the shells of the nuts instead of the meat of the nuts into a blender. Just keep in mind, though, that I grew up with dried kidney beans in our cupboard constantly. So I've always been accustomed to knowing that they and any other dried legume need to be cooked/boiled.

    I never would´ve thought of tossing in dried beans either. In fact, I never knew about the hazards of that until now! Quite an informative thread.

    I have a high-powered Vitamixer which basically pulverizes anything into liquid, so nothing in my smoothie is chunky. I usually throw in a few nuts and other things as well, so it wasn't unusual for me. I just didn't know about the toxins in kidney beans. I don't want anyone else to learn the hard way. It was bad.

    Well, I'm glad you posted this thread. It definitely helped several avoid such consequences.

    Again, very glad you're okay
