Foods That Are High in Lectins

This type of protein is found mainly in raw grains and legumes. However, you can still find them in certain seeds which become leaves as in plant sprouts. Apart from those, you can also find them in certain vegetables and dairy products. They include:

The Benefits of Lectins

Are lectins bad for your health? There are different types of foods which contain this type of protein. This means that lectins play different roles in the body which are vital for development. Some of their benefits include:

Immune Regulation

These proteins help to regulate cell adhesion. This is important in immune regulation and improving the immune function. Some research studies indicate that lectins also have anti-microbial properties which make them effective in preventing infections.

Fighting Fungal and Viral Infections

Lectins are effective against fighting various fungal and viral infections. Multiple in-vitro trials suggest that they may help to prevent the growth of specific fungus, especially the one that’s responsible for yeast infections.

Cancer Treatment

A research report published in Cell Proliferation indicates that certain lectins can help treat cancer. Some of these proteins have anticancer properties. These make them effective in minimizing the symptoms and spread of cancer.

Side Effects of Lectin

Consumption of foods with high amounts of lectins is often associated with numerous health effects. There is a direct connection between these proteins and inflammation in the body. Some of the potential downsides of lectins include:

Digestive Issues

These proteins are not easy to digest. So, consuming foods which are rich in lectins may cause damage to the gut wall. As a result, you may end up suffering from leaky gut syndrome. This condition is usually characterized by a permeable gut.

Autoimmune Conditions

These proteins influence how the immune system works. So, there are high chances that they can also result in result in autoimmune diseases like rheumatoid arthritis. Lectins can attack healthy cells in the body and lead to cell inflammation.

Nutritional Deficiencies

Lectins are not easy to digest which means that they form unnecessary bulk in the digestive tract. They also have anti-nutrient properties. So, taking foods which have high amounts of these proteins can increase your risk of nutritional deficiencies.
