Hygiene OF digestion. (2)
On the objectives of different elements to this, the experiment has been shown by physiologists that the superior element carbon, which generally consists of more food, serve three purposes in the body;
1. They provide material for the production of heat;
2. They are a source of strength when taken in conjunction with elements of other food;
3. They replenish the fatty tissues of the body. Of the elements carbon, starch, sugar, and Fats, Fats produce large quantities of heat in proportion to the quantity, the more heat is developed from a pound of fat than the same weight of sugar or starch, but this clearly benefit more than counterbalanced by the fact that Fats far more difficult than from digestion is the element carbon, and if relied upon to provide adequate material for the body heat, be more productive of mischief in overtaxing and producing disease of the digestive organs. The fact that nature has made more provisions of starch and sugars of Fats in the nature of the human diet, seems to indicate that they are intended to be the main source of carbon from the food, however, Fats, when taken in proportion as they are, very important and important element of food.
Nitrogenous food elements especially nourish the brain, nerve, muscle, and all the more high-vitalized and active tissues of the body, and also a stimulus to the network change. Thus it can be said that the food is less in this element is particularly poor food.
The main inorganic elements that are phosphates, carbonates from the potash, soda, and lime, furnishing material assistance necessary for bone and nerve.
The right combination of food.
-----------------------------
Although it is important for our food should contain some all of the various elements of food, both in animal and human experiments indicate that it is the important element, especially the nitrogenous and carbon, used in a certain proportion, as the system is only able to appropriate a certain amount from each , and all excess, especially of nitrogenous elements, is not only useful, but even harmful, to save the system because the additional surplus on duty excretory and digestive organs. The relative proportion of this is the element needed to perfect the food requirements of the system, is six of carbonaceous to one of nitrogenous.
Many scientists have devoted careful study and experiment for the determination of the number of individual elements of the food needed to feed every day from people under various conditions of life, and he has come to the public received from the nitrogenous material which should be the one of six nutrient taken, about three ounces is all that can be done in the use of twenty-four hours, by a healthy adult average of the weight, the amount of work is being conducted. Many articles are food, but less well in one of the elements, and must be supplemented by other articles containing the missing element in superabundance, since to employ a diet in which one of the elements that is less nutritious, although in mass may all digestive organs can manage, it is hunger, and opportunity will result in a serious time.
Thus it is clear that much care should be implemented in the selection and combination of food materials. As the first science is important in education and cooking housekeepers, as they fall from the selection of food for daily needs of the family, and they should not only understand what foods are suitable to supply this, but how to combine them according to physiological laws - Act.
