WE have been asked to give an opinion regarding the theory that vegetables growing under the ground, such as potatoes, are unwholesome, because deprived of sunlight. Now the potato is simply the storehouse for the potato plant. The material of which the potato is composed is combined in the leaves, under the influence of bright sunlight. It is then carried down to the cellar, as it were, for safe keeping. The farmer often puts his apples in the cellar for winter, without any injury to the apples. Neither the flavor nor the nutritive properties of the fruit are affected by the change. Again: the center of an apple or a grain of wheat is not exposed to direct sunlight. The changes which take place in the foods as a result of the sun's action take place in the green cells of the leaf, and it matters little afterward where this material is stored. Physiological tests conducted by the writer showed conclusively that the starch of potatoes is digested by the saliva more rapidly than the starch of the cereals,—wheat, corn, and oats. It is an excellent food when properly cooked, but should be eaten in connection with some food containing an excess of nitrogen, as peas, beans, or lentils.—Pacific Health Journal.
