Modern medicine has proved that frog meat not only has no special nutrition, but also affects human health and even gets parasitic diseases if eaten too much. Frogs generally live in farmland, and crops use more chemical fertilizers and pesticides. The increase and unreasonable use of pesticides make pests resistant, and the emergence of drug resistance promotes the continuous increase of pesticide consumption.

Frogs often devour pests and water sources with fertilizers and pesticides, and pesticides accumulate in frogs. If people eat them, pesticide residues will enter the human body. Pesticide residues will poison the human body through the "food chain", forming chronic pesticide poisoning, leading to various cancers and tumors; It may even lead to congenital malformation of the baby.
