POTATOES ARE WELL NOURISHED, HAVE HIGH NUTRITIONAL AND PHARMACEUTICAL VALUES, CONTAIN VARIOUS COMPONENTS SUCH AS PROTEINS, MINERALS (PHOSPHORUS, CALCIUM, ETC.), VITAMINS, AND HAVE A MORE RATIONAL NUTRITIONAL STRUCTURE, KNOWN AS “UNDERGROUND APPLES”. IT CONTAINS PROTEIN AND VITAMIN C, VITAMIN B1, VITAMIN B2 MUCH HIGHER THAN APPLES: ONE AND VITAMIN C 10 TIMES MORE THAN APPLES. TWO, B VITAMINS ARE FOUR TIMES MORE THAN APPLES. THE LEVELS OF CALCIUM, PHOSPHORUS, MAGNESIUM AND POTASSIUM VARY FROM SEVERAL TO SEVERAL DOZEN TIMES THOSE OF APPLES, ESPECIALLY POTASSIUM, AND CAN BE SAID TO RANK FIRST IN VEGETABLES.
