What Are Lectins?
Lectins are a type of protein that is found in nearly all foods, including grains, animal products, plants, and legumes.[*]
Lectins serve a variety of functions in the plant and animal kingdom. For plants, lectins act as a defense mechanism against predators. In animals, lectins play a role in gut function, cell growth, and the immune system.[*]
While some lectins are beneficial, others can be harmful.[*] The type of lectin found in a food determines its effect on the body.

Natural Toxins in Food
Toxins in food are a real thing. Some foods contain toxins that can cause illness or even death.
For example, ricin is a toxin found in castor beans.[*] It has been suggested that as few as two or three castor beans may be fatal if consumed.
Cyanide is another natural toxin found in cassava, an African root vegetable.[*] If not properly prepared, cyanide poisoning can occur.
Lectins are a type of natural toxin found in some plant and animal foods. They’re not as dangerous as ricin or cyanide, but they can still cause problems for some people if you eat them in large quantities.
Do vegetables contain lectins?
Many vegetables contain lectins, but they are generally not harmful to most humans. Some people believe that a lectin-free diet may be beneficial, but there is limited scientific evidence to support this claim. Most of the research has been done on animals, not people.
More research is needed to know the true effects of lectin in the diet.

Lectin-Free Diet Tips
If you want to avoid lectins in your diet, it’s vital to ensure that you’re still getting adequate nutrients from other foods. Many of the foods eliminated from this diet are high in dietary fiber, which is good for your health. To make up for the slack, eat sufficient fruits and veggies or take a fiber supplement. Here are some other tips to keep in mind:
Soak and boil beans before eating them to reduce the lectin content.
You can also reduce lectin content by fermenting or sprouting grains and beans.
An elimination diet can help you figure out if you have a food sensitivity to any lectins. To do this, simply remove one food at a time and see if your symptoms improve.
Consider consulting a health provider or nutritionist to ensure that you are not missing out on any critical nutrients.
