Foods should be prepared with simplicity and variation, perhaps only three or four dishes at a meal, and properly cooked. Food should be carefully chosen and prepared with intelligence and skill. Avoid the use of grease in foods. Lard, butter, and hydrogenated vegetable fats may be classified as grease. If using oil, use natural oils sparingly, such as olive, flax, or canola, and keep it refrigerated.
Avoid sugar. It is not good for the stomach, because it causes fermentation. Milk and sugar clog the system, irritate the digestive organs, and affect the brain. Sugar, when largely used, is more injurious than meat.
Eat raw vegetable salads or raw fruits before the main course. This will stimulate and assist digestion, and help avoid overeating of cooked foods. Fruits and vegetables should not be eaten at the same meal. Eat fruits at one meal and vegetables at another.
