Intemperance is seen in the quantity as well as in the quality of food eaten. The Lord has instructed me that as a general rule we place too much food in the stomach. Many make themselves uncomfortable by overeating, and sickness is often the result. The Lord did not bring this punishment on them. They brought it on themselves, and God desires them to realize that pain is the result of transgression. CH 576.3
Daily abused, the digestive organs cannot do their work well. A poor quality of blood is made, and thus, through improper eating, the whole machinery is crippled. Give the stomach less to do. It will recover if proper care is shown in regard to the quality and quantity of food eaten. CH 577.1
Many eat too rapidly. Others eat at one meal varieties of food that do not agree. If men and women would only remember how greatly they afflict the soul when they afflict the stomach, and how deeply Christ is dishonored when the stomach is abused, they would deny the appetite and thus give the stomach opportunity to recover its healthy action. While sitting at the table we may do medical missionary work by eating and drinking to the glory of God. CH 577.2
