The Use of Candy in Diet
Candy, is an energy-giving food, but unfortunately perhaps, it is not (at all times) a most desirable energy-giving food. Sugar exists in candy in concentrated form. Such sugar is irritating to the organs of digestion.
Sugar is contained in large quantity in some fruits, especially in dried fruits: figs, dates, prunes, etc. These fruits are a much better source of sweets for children than is candy, because they do not contain as much sugar, and have, in addition, valuable food materials in the form of ash. Note the large quantity of carbohydrates and ash in raisins.
Candy should never be used to excess or at the wrong time. A little eaten at the end of a meal is not harmful to the normal person. At that time the sugar is diluted because it is mixed with other foods. When diluted it does not irritate the digestive tract to the extent that it would if eaten between meals with no other foods. It is well to drink a generous quantity of water when eating candy or other sweets. Since molasses, honey, and maple syrup are not so concentrated as is sugar, they are desirable sweets for children – provided they are used moderately at the right time, and are mixed with other foods.

The old book mentions the role of “ash” in the diet. Today ash would be called minerals.
