The Plant Paradox

In addition to the potential to cause health problems, lectins can also stimulate weight gain. The reason that wheat became the grain of choice in northern climates is thanks to a uniquely small lectin in wheat, known as wheat germ agglutinin (WGA), which is responsible for wheat’s weight-gaining propensity. You read that correctly. Wheat helped your ancestors gain or maintain weight in ancient times when food was often scarce; back then, a “wheat belly” was a great thing to possess! And guess what? That WGA in the “ancient” forms of wheat is just as present in modern wheat—hence the weight gain.
