_To Save Wheat_. Potatoes to save wheat! The great potato drive to utilize the surplus of our huge 1917 potato-crop, 100,000,000 bushels above normal, has fixed in every one's mind the interchangeableness of these two foods. Potatoes are one-fifth starch--almost the same quantity as in cooked breakfast cereals. Because of this starch, they give as satisfactory a fuel as wheat or corn or any other cereal. One medium-sized potato supplies the same number of calories as a large slice of bread, and contains more mineral salts than white bread. Europe has learned to eat potatoes instead of wheat. When bread has been short potatoes have been the mainstay in every country. They are to-day the largest single element, in terms of energy, in the German war ration. Sweet potatoes are also first-class wheat-savers. So to a lesser extent are most vegetables and fruits. Very few except white and sweet potatoes contain much starch, but many of them have considerable sugar, which serves as fuel just as starch does--carrots, beets, onions, parsnips, and practically all fruits such as bananas, oranges, and grapes. _To Save Sugar_. We want sugar, of course, both for fuel and flavor. The vegetables and some fruits have their sugar so covered up by other tastes that it does not help to make the food sweet. It does, of course, serve for fuel. Bananas especially are fuel foods, containing much starch when green, which changes to sugar as the fruit ripens. The sweetest fruits are the dried ones--dates, figs, raisins, prunes. They have so much sugar that they can well be used in place of candy. _To Save Fat_, Although few common fruits and vegetables contain fat, jam is a real fat-saver. It is of high fuel value, and has the advantage of being a "spreading material" so that it can replace butter with bread and cereals. Jam is of great importance in Europe to-day and all the Governments have taken steps to keep up the supply. It is a regular part of the English army ration. _To Keep the Nation Well_. An increase in the use of vegetables and fruits is practically sure to mean an increase in health. Many of us, especially city-dwellers, do not eat enough of them. Many a young girl who "does not like vegetables" probably owes part of her languor to inadequate diet. The old-fashioned "touch of scurvy" formerly noticed at the end of the winter and even now not an unknown thing, was probably due to lack of vegetables in the winter diet. The constipation which is so disturbingly prevalent can usually be cured or prevented by eating vegetables and fruits in sufficient quantities. One of the most serious limitations in the diet of many of the very poor is the lack of vegetables as well as milk and the unduly large proportion of meat and bread. In a community in New York City with high mortality rate, 75 mothers whose diet was observed, ate vegetables on the average only twice a week, and fruit about the same number of times.
