Okay kiddo, so have you ever had a friend who you couldn't play with because they made you feel yucky? Well, there's a type of protein called lectins that can do that to our bodies too.
Lectins are like little sticky and grabby hands that are found in some of the foods we eat. They attach themselves to our digestive system, which is like a long tube that helps our body break down the food we eat and turn it into energy. When lectins grab onto our digestive system, they can cause some trouble.
Sometimes, lectins can make our tummies hurt or give us a squishy feeling. That's because they can damage the lining in our gut, which can make it harder for our body to do its job of turning food into energy.
But not all lectins are bad. In fact, some lectins are actually very helpful for our body. For example, they can help our immune system fight off harmful germs and bad bacteria.
So, in summary, lectins are proteins that are found in some of the foods we eat that can be harmful to our digestive system if we eat too much of them. But some types of lectins can actually be good for us too!
