oh snap grandma’s slow cooker chili is actually killing you all right hear me out I’m gonna make some sense of that all right I just had to make this a little bit light before I get into the scary stuff I’m talking about lectins today lectins are a very very hot topic that people hit me with questions about all of the time basically all lectins are are a form of protein that encourages the binding of certain molecules basically what it does is it causes a certain sugar molecule to bind to the membrane of another cell so since it is sugar binding it means that lectins attached to carbohydrates the purpose of a lectin attaching to a carbohydrate is so that they can communicate with other molecules in the body better that’s all we’re trying to do so lectins cause these cells to basically clump up let’s just simply put it like that because they’re clumped up it’s easier for them to communicate without the involvement of the immune system normally when cells communicate there is a small involvement of the body’s immune system so lectins are actually a positive thing but the negatives come into the equation when we start talking about how lectins are digested you see because lectins are so big and because there’s so many things bound together they run through our digestive system like an absolute maniac like a raging bull just totally destroying things let me explain it like this inside your intestinal tract you have these things called villi villi are basically like little fingers like things that stick out of your intestinal tract right so you’ve got your small intestine and it’s got these small little fingers that absorb nutrients so food comes along and it goes in between the villi okay and that’s how it absorbs but when you have lectins involved lectins cause the molecules to bind together so now your veal I have no longer become an absorption mechanism they’ve become bowling pins and the lectins are a bowling ball and it comes through in a pummels them and it destroys them when that happens you’ve inhibited digestion because you no longer have the villi to absorb the nutrients so now instead of having all of this surface area to absorb nutrients you have this so you have just completely eradicated the chance of absorbing some really good nutrients that’s where lectins cause a big problem and that’s where they get such a bad rap so to add insult to injury once the villi is damaged you now have trauma trauma equals inflammation inflammation equals antibodies antibodies equal a myriad of other issues that occur within the intestinal tract but it gets even worse since you’ve caused damage and since you’ve caused trauma and since you’ve now caused inflammation you have opened yourself up to those lectins getting into the bloodstream through what’s known as a leaky gut now I don’t want to spend a lot of time on a leaky gut because you’ve probably heard about it basically it causes an opening so that things can leak through the intestinal tract and into the bloodstream that ordinarily would not this means things like lectins these lectins barely belong in the digestive system let alone in the bloodstream so now these lectins are floating around the bloodstream we have inflammation being triggered up everywhere but we also have another issue lectins really have a nice affinity for insulin receptors and a nice affinity for leptin that’s leptin with a pee receptors what does that mean it means that lectins can ultimately lead to diabetes and diabetes like symptoms or at least insulin resistance but it can also lead to leptin resistance which is what dictates whether your metabolism goes fast or slow leptin communicates with your brain and I know that’s confusing because of lectin and leptin so don’t get too caught up on that basically all it means is that if these lectins get through your intestinal tract they can really function stuff up now normally a little bit of damage to those villi is normal right so if you consume food it’s going to break it down a little bit but it actually encourages them to grow back stronger but when you have lectins they damage them so bad they don’t grow back very well and continually the lectins basically blunt the regrowth of the v leg so now you have the situation where the villi is damaged and it can’t regrow so can you cause permanent damage to your gut not really but you can cause long-term enough damage that is going to be hard to absorb nutrients for quite some time but that’s enough negative scary stuff about lectins because we really have to talk the cold hard truth here again 30% of the foods that we consume have lectins lectins are there as a good mechanism for ourselves to communicate so then why are they so bad well they’re only bad if you’re consuming a ton of them okay we really just need to consume them in mod raishin because a small amount can actually be good you see a small amount can activate what’s known as the complementary immune system which can actually help fight pathogens so lectins can work advantageous li towards good health with your immune system but again just in moderation and a lot of it comes down to how you cook the foods that contain lectins you’re not going out and eating raw beans are you I sure hope not because if that’s the case then we have some other things to talk about but the thing is lectins are prevalent in raw foods and if you’re not cooking them all the way so when you look at beans you simply want to be soaking them for a long time before you cook them which if you look at the package usually it tells you to do so to begin with so soak your beans soak your grains soak your legumes soak your lentils and then cook them all the way through at a moderately high temperature the other thing that causes excess release of lectins is cooking them slowly so if you slow cook beans or you slow cooked chili you’re going to have more lectins than if you soak your beans and then cook them at high heat like you’re supposed to it’s plain and simple you really should just follow the directions that are on the label and you’re probably not gonna have that much of an issue with elect ins but also you may not want to be consuming copious amounts of beans to begin with one you have other things that are going on like your body lacks the enzymes to break down a lot of the proteins and beans to begin with but you also have a family to be concerned with and I don’t think that they want you eating a lot of beans day in and day out so anyway there you have it that’s why lectins are not as bad as you think they are but they are bad if you let them be bad you just have to know the science you just have to know the details and as always make sure that you comment and let me know what other videos you want to see this is a perfect example of a video that a lot of people wanted to see and here we have it so keep it locked in on the top of still our channel and I will see you in the next video go easy on those beets tell your grandmother chill out

What are Lectins?

They are sugar-binding (bind to carbs) and offer a way for molecules to stick together without getting the immune system involved.

They are resistant to human digestion and they enter the blood unchanged.

This can be helpful for encouraging particles at the molecular level to interact with one another – also necessary for some physiological functions, but in some cases they can be harmful.

We don’t digest lectins and often produce antibodies to them – Almost everyone has antibodies to some dietary lectins in their body, which means our responses vary and certain foods may become intolerable (1)

Foods with Lectins-

Lectins are found in about 30 percent of foods and are especially concentrated in grains and legumes.
Also high in nightshade vegetables such as eggplant, tomatoes, potatoes & peppers.

Lectins and Gut Issues-

Ingesting lectins can cause flatulence. GI distress happens because lectins can damage the intestinal lining. Lectins bind with the intestinal lining, specifically the villi of the small intestine and when the villi are damaged by lectins the body is unable to effectively digest and absorb nutrients from the small intestine. This can lead to a leaky gut in which the intestinal lining has open gaps and now lectins and other particles and pathogenic organisms are able to get directly into the bloodstream. Lectins can blunt the repair so our cells can’t regenerate as fast as they need to in order to keep the intestinal lining secure. Thus, our natural gut defenses are compromised after the damage occurs and the gut can become “leaky,” allowing various molecules to pass back and forth amid the gut wall.

When enough lectins are consumed, it can signal our body to evacuate GI contents. This means nausea, vomiting, cramping and diarrhea. It’s similar to consuming large amounts of alcohol, which can damage the GI lining and cause GI evacuation.

When lectins affect the gut wall, it may also cause a broader immune system response – Symptoms can include skin rashes, joint pain, and general inflammation, as well as a leaky gut (1,2)

Additionally, lectins that are free floating in the bloodstream have an affinity for the insulin and leptin receptors and are believed to desensitize these receptors contributing to insulin and leptin resistance in the body (3)

Solutions – Soaking, Fermenting-

While lectins do have some negative effects, they usually only occur when consumed in high amounts – Some level of lectin consumption can actually provide a mild stress to the digestive system that strengthens our digestive capabilities.

Lectins activate the complement immune system (part of innate immune system), which helps fight pathogens – for example, the lectin pathway can help fight off pneumonia.

The key is not to over consume, but there are ways in which you can reduce the amount of lectins in your food.


Soaking and boiling legumes for adequate amounts of time can remove virtually all of the lectins – Soaking beans and other legumes in water and then cooking them in water at or close to 100°C or 212°F (i.e. boiling) appears to be highly effective at inactivating legume lectins.

If you don’t soak your beans long enough, you may not be able to encourage the heat to penetrate deeply enough to destroy all of the toxins.

Fermenting seeds and grains is also favorable as you are essentially allowing beneficial bacteria to eat the lectins.

Should be noted that low temperatures can actually increase lectin activity. So a slow cooker may not be ideal for cooking beans.
