That a raw apple eaten at the end of a meal not only acts as a cleanser of the teeth, but also helps to preserve the “alkaline reserve” in the blood, and scientists have discovered that this question of an acid or “alkaline reaction” lies at the bottom of many ailments, as well as having a definite influence on the decay or non-decay of the teeth.
That the mineral salts of the apple have a beneficial and stimulating effect on the kidneys, while the fibrous portion (especially if eaten raw, including the peel) furnishes a certain “roughage” or bulk which helps to regulate the digestive functions.
