    I have a blood disorder (Hereditary Coproporphyria, a hemoglobinopathy) so these things really matter to me. I soak my beans until they’re about to sprout, then cook. I don’t care how many people say “I don’t think it matters,” because for me it does matter. I also had part of my GI tract actually split apart in my body ten years ago. I should’ve died that day but my son got me to the hospital in time. But it took me years to figure out that I lacked the “real estate” to absorb nutrients now. I have to infuse B vitamins by an IV now, and I eat very carefully! Thanks for this information and clarifications.

    This is the same thing about Runner beans? I've heard people talk about them, as well.

    Seems like soaking beans is done often in indigenous cultures. They just figured it out by themselves that the soaking should be done.

    I rince my dry beans numerous times prior to cooking.
    Our mom use to pour them out of bacon table and check for tiny rocks. Then rinsed several times.
    RICE: We were taught that rice has arsenic, and so we're to rinse untill the water is clear before you cook and eat it.

    I have completely stopped using kidney bean, instead I have switched bean choice for my chili… i use Red Beans instead… but i use the dry bean, so i go through all the fast pre-boil 2 minutes then do pre-soak for 2 hours. Then drain, rinse, then cook for as long as needed, usually only One and a Half hours.

    And That right there (the lectins) is why you should NEVER eat Kidney Beans raw, fresh from the garden….that can make you sick and can kill you eaten straight from your garden. Now i know the science behind the why you dont eat raw!

    My son started having negative reactions everytime he'd eat anything with kidney beans. From the school, to family to KY own cooking he would have issues. He ahd never had a problem before. He'd have terrible upset stomach and diarrhrea. No one else had the issue. It would last a day and then be over. So we stopped using them. It was only for about a year and now, after 10 years he can actually eat them without problems.

    I always buy my kidney beans canned so haven't had to worry about this. I have used my slow cooker to cook garbanzo beans and they turn out great. I have also used my instant pot to cook pintos unsoaked when I forgot to soak them but the end product is better when they are soaked. I will definitely have to research this a little more!

    This is great information! I was told I was being ridiculous. Especially that I used filtered water to soak them in. I explained that because the water is absorbed. Now, I will pass this information on to my bean loving friends. Thank you so much!👍🏻😃

    Can you speak more about the issues cause by the lectins. And can you safely quick soak these beans ( ie: boil for 2 minutes. Sit 1 hour then rinse and drain. Then finish cooking.) ??

    I remember hearing people say, when I was a kid, that the reason you soaked the beans and discarded the soak water was because it would "take away" the excess gas symptoms some people experience. This was presented to me as hearsay and "folk" tales, not scientific. And I disregarded that, thinking, no way. However, now, hearing about lectins causing gastric distress…yeah, I can see where that idea came from.

    Thanks for the video. It was very informative. So apparently, these lectin’s are there to protect the seed from being devoured before it can sprout into a plant. According to Dr. Jason Crean, an avain expert, another way to deactivate the lectins is to sprout the beans after soaking. They put out their own enzymes to soften their shell during this process. Tiny beans only need to be soaked for about an hour, whereas some beans have to be soaked for 24 hours before they are sprouted. But that’s how you can make sprouted bread or in my case I have parrots and I can feed the beans to my parrots as sprouts. Highly nutritious. According to Rick Bayless, a Mexican food expert, Mexicans do not soak beans like Americans. And the way to get past all the gas and problems is to just eat a lots more beans. Personally, no matter what I do to certain beans they bother my stomach and cannellini beans are one of them. Maybe I can soak them longer and that might help.

    Thank you Pam for this video. I've been wondering about lectins for a while. I listened to a doctor on YouTube and read his book. He made it sound like they are in a lot of our foods and causing a lot of our illnesses. Especially in our guts, causing our guts to leak.

    I made many pots of chili over the last45 years. Never dumping the soaking water. Often not soaking at all. Just a long slow cooking time. Who knew about lectins. Not me. Thanks for the explaination.

    What about the Fast Soak Method (hard boil x 2 mins, cover, remove from heat & wait one hour) that was reported and recommended beginning in the 1950’s, I think? Is that safe? Also, does freezing help? We use to Fast Soak, drain, and freeze. Doing this caused the beans to later be cooked in about 15 mins vs on hour or more. Thanks.

    I'd also like to know why you didn't say to rinse after the 30 minutes of cooking the beans. Wouldn't the lectins be in that water? Also, I've heard people call for aquafaba in recipes (water from can of chickpeas); would that be safe?

    I've been reading and watching some videos of doctors who say lectins in any amount are harmful to us and prevent us from absorbing nutrients from other foods like protein from meat, eggs, etc. Is there any truth to this? I'm a big veggie eater and grow a lot of my own produce but was concerned after hearing this. Many "experts" in the carnivore diet community believe this. I believe we have evolved to eat a wide variety of foods but was wondering about this.

    In October and November, would consider creating videos on homemade food gifts for the upcoming holiday season? I like gifting things like homemade vanilla extract or canned chocolate jams. I’d love to see what concoctions you would come up with

    Thank you so much for this information. I never knew any of this as I have never cooked kidney beans from scratch. I only have done the white navy beans to do with a ham bone. Wow this is so interesting. You always bring us something new. Thanks

    Wow i had no idea cannellini beans were in the same boat as kidney beans. I grew them in my garden for a few years. Good thing I cooked them well before eating. I even had them on the same trellis as my pole beans. SO its possible i ate some of the young ones. 😮 Wont be doing that again. Thank you for the informatioN!! 😅

    I just used some White Beans to create a "Bushes Beans" imitation recipe and canned about 12 jars – they turned out delicious, but boy, it took both the overnight soak, the 30 minutes boil, and then the canning to get them soft enough to enjoy eating. The recipe turned out great, though!

    Question? PAM, You say after soaking the beans to always discard and rinse the beans before boiling….So does that mean the water that the beans were boiled in is ok to keep then? If not why? You said the beans that were fully cooked, that the lectins have been
    deactivated so does that mean for the water they’re in too? And I don’t need to drain a second time? Just curious! And I’ve always pressure cooked my beans. Sometimes I soak other times I haven’t. Is that bad? Or does pressure cooking the beans do the same in deactivating the lectins, without having to soak or rinse ? I’m talking about a regular pressure cooker not the kind you would bottle with. And no it’s not an instant pot…
