Cereals and Grains
Cereals contain high levels of a certain type of lectin, wheat germ agglutinin (WGA). It is also found in rice, barley, and rye. Studies show that it can lead to various medical disorders, such as intestinal permeability [5]. Ironically, studies also show that foods high in WGA may reduce the risk of cardiovascular disease [6] and type 2 diabetes. Grains can help regulate weight gain. Experts advise people to limit their consumption of grains and cereal.
It is important to note that high-processed bread and packaged foods containing wheat may cause gastrointestinal disorders, while whole grains like brown rice may not.
