The table of food-values will easily enable the reader to ascertain the proportion of Fat in each kind of food. The following indications of dietetic error may prove useful:-- [Sidenote: =Signs of Dietetic Mistakes.=] Excess of proteid matter causes a general sense of plethora and unbearableness, nervous prostration or drowsiness after meals, a tendency to congestion (often resulting in piles, etc.), headache, irritability, and bad temper. A continuous deficiency of it would tend to produce general weakness and anæmia. Excess of carbohydrate matter (starch), especially if not sufficiently cooked and not well masticated, produces dyspepsia, flatulence, pain in the chest and abdomen, acidity (resulting in pimples and boils), and an inflammatory state of the system. Deficiency of it (or its equivalent, grape sugar) would produce lack of force and physical exhaustion. Excess of fat tends to cause biliousness. Deficiency of it results in nervous weakness, neuralgia, and low temperature of the body. [Sidenote: =Food for Brain Workers.=] It is important to remember that the more _physical_ energy we put forth, the larger is the amount of proteid we require in our diet--and vice versa. Brain workers of sedentary habits require but little proteid, and quickly suffer from indigestion if this is taken too freely. For such, a very simple diet consisting largely of dried and fresh fruits, nuts (flaked or ground), milk, eggs and cheese, and _super-cooked_ cereals (such as wholemeal biscuits, and toast, Granose and Kellogg flakes, and well baked rice dishes) will be found to be the most suitable. In order to supply the brain with phosphates it is very important that mental workers should take whole wheat bread instead of the emasculated white substitute which is provided almost everywhere. It is the outer part of the grain that provides brain-food (combined with an _easily assimilable_ form of protein), and many of our urban bread winners break down because they are deprived of the essential food elements therein contained. To take 'standard' bread does not meet the case, and every food-reformer who wants to keep really fit should demand and obtain well baked and unadulterated wholemeal bread. I feel convinced that if every growing child and every mental toiler could always be supplied with bread of this type, the deterioration of our British race would soon be arrested and we should witness signs of physical regeneration. 'Artox' and 'Ixion' brands of pure whole wheatmeal are the most perfect I know of at the present time, and delicious bread can easily be made from them if the recipe printed on page 114 is followed. =FOOD CHART.= =Showing how to obtain sufficient (1) Protein--for body building.
