Protein is adequately present in almost all natural foods, particularly beans, peas, nuts, seeds, grains, and vegetables. In order to become protein deficient, you would need to consume only fruit, only highly processed junk foods, or simply not take in enough calories daily. Teachers, educational institutions, media, and a public that has been mis-educated for a long time support this practice. God designed our bodies to be fueled primarily by clean-burning carbohydrates. People displace needed carbohydrates when they consume more protein and fat than is necessary or beneficial.
Carbohydrates are abundant in natural foods.
