[Sidenote: Application of the term "sweets" as herein used] In order to avoid repetition, all articles containing sugar are referred to throughout this work as _sweets_. By "sweets" I mean sugar, sirups, honey, and all foods containing sugars, such as desserts, soda-fountain drinks, and the limitless number of confections. While carbohydrates rank second in importance in the human diet, yet Nature has made no provision for sugar being taken in its concentrated form. In this form it is the most severe article of human diet, and to its use can be traced the origin of a vast number of stomach, intestinal, and other disorders. Superacidity, fermentation, intestinal gas, and the large number of sympathetic disorders that follow these conditions are caused largely by the overconsumption of sugars. It would be equally as important for the Federal Government, or the States, to regulate the manufacture and the sale of confections as to regulate the manufacture and the sale of intoxicating liquors. VEGETABLE OILS [Sidenote: Value of vegetable oils] Vegetable oils form too small a portion of the modern bill of fare. Oils of vegetable origin, whether taken in their natural form or pressed out, and used with other foods, are the most valuable nutrients known for the production of heat and energy. By this statement I mean to convey the idea that a given quantity of fat will produce more heat and energy than any other article of human nutrition, and that vegetable fats are more valuable than animal fats, because they are more adapted to the fat metabolism of the human body, and less likely to contain harmful substances. Vegetable oils contain a larger per cent of olein, which is considered the most palatable and the most valuable fat known. [Sidenote: Olives and olive-oil] The olive is a unique plant, standing along the border line between fruits and nuts. Ripe olives contain from 40 to 60 per cent oil, the best quality of which is extracted by cold pressure, the cheaper grades being pressed out at higher temperature. The superiority of olive-oil is due to the fact that it is composed almost wholly of olein; that it contains very little fatty acids and other impurities, and has a mild, sweet, and agreeable flavor. The adulteration of olive-oil has been extensively practised, but the agitation of pure food, and the demand for same are improving the quality of this excellent article of food. [Sidenote: Cottonseed-oil] Cottonseed-oil is the largest vegetable oil industry in America. It is also the cheapest of vegetable oils. The cottonseed-kernel from which the oil is taken is not an edible product. Though used as cattle feed, it contains alkaloid substances which sometimes have a poisonous effect when fed too generously.
