Cheese should never be introduced into the stomach.
Testimonies for the Church 3:136TSDF 14
Children are allowed to eat flesh-meats, spices, butter, cheese, pork, rich pastry and condiments generally. They are also allowed to eat irregularly and between meals of unhealthful food. These things do their work of deranging the stomach, exciting the nerves to unnatural action, and enfeebling the intellect. Parents do not realize that they are sowing the seed which will bring forth disease and death.
The Ministry of Healing, 302TSDF 14
Butter is less harmful when eaten on cold bread than when used in cooking, but, as a rule, it is better to dispense with it altogether. Cheese is still more objectionable; it is wholly unfit for food.
Tract Regarding the Use of Flesh Foods (Eight page tract)TSDF 14
I have a large family which often numbers sixteen. In it there are men who work at the plow and who fell trees. These men have vigorous exercise, but not a particle of flesh of animals is placed upon our table. Meat has not been used by us since the Brighton camp-meeting. 1894. It was not my purpose to have it on my table at any time, but urgent pleas were made that such an one was unable to eat this or that, and his stomach could take care of meat better than it could of anything else; then I was enticed to place it on my table. The use of cheese also began to creep in, because some liked cheese. But I soon controlled that.
Christian Temperance and Bible Hygiene, 46-47TSDF 14Many a mother sets a table that is a snare to her family. Flesh-meats, butter, cheese, rich pastry, spiced foods, and condiments are freely partaken of by both old and young. These things do their work in deranging the stomach, exciting the nerves, and enfeebling the intellect. The blood-making organs can not convert such things into good blood. The grease cooked in the food renders it difficult of digestion. The effect of cheese is deleterious.
Letter 62, 1903TSDF 14
Our fare is simple and wholesome. We have on our table no butter, no meat, no cheese, no greasy mixtures of food. TSDF 14.1 - TSDF 14.6
