Lectins are a type of protein found in various plants, especially grains and legumes, that can bind to cell membranes. They serve a protective function for plants as they grow but can also have negative effects on human health when consumed in large amounts. Despite their natural origins, dietary lectins can be damaging and unhealthy due to their resistance to human digestion and their ability to bind to the cells lining the digestive tract. This post covers the reasons behind the potential harm caused by dietary lectins and provides advice on how to minimize their negative impact on our health.
