These are the vegetables other than potatoes and dried peas and beans and fruits. Fruits and vegetables contain certain mineral elements, which are not present in sufficient proportions in the meats, starches, and fats. Furthermore, the products of their digestion and burning in the body help to neutralize, or render harmless, the waste products from meats, starches, and fats.

How Nuts should be Used. Another form of fat is the "meat" of different nuts walnuts, pecans, almonds, etc. These are quite rich in fats, and also contain a fair amount of proteins, and are, in small quantities, like other fats, appetizing and useful articles of food.

In departing from food customs there is a natural timidity lest the new food shall in some way be less healthful than the old. Recent scientific researches have revealed a hitherto unsuspected property in butter, a discovery which has aroused some concern as to whether we can safely substitute other fats for it.

Remember, fats, animal or vegetable, subjected to high heat become indigestible and toxic and make anything they're cooked with indigestible; salt is a toxic drug; cheese, hard enough to digest as it is, when raised to high temperatures as it is when making pizza, becomes virtually indigestible and cheese inevitably contains a lot of butterfat which, though saturated animal fat, when raised to high temperatures, still becomes slightly rancid.

She noticed that a great many of her patrons had taken second helpings, and that threw her out in her calculation of quantities, while the relative digestibility of the protein and the fats in pork depend so much upon its preparation that she could not approximate the virtue of Hitty's bill of fare without consultation with Hitty.

If one were to choose for example, a diet of meat, eggs, nuts, corn starch, tapioca, sugar, fats and oils, i.e., diets which will be almost completely digested and absorbed, leaving a very small amount of undigested material in the intestines, the bulk of the material in the intestines would be so small that they would not be stimulated to contract.

Many of these children appear to have a lowered tolerance for fats of all sorts, and it may be necessary to limit strictly the consumption of milk, cream, butter, and so forth. A daily administration of a small dose of alkali by the mouth is credited with preventing attacks.

But the Bread culture itself is always supplemented by some form of milk product, of which cheese is typical. It is almost always supplemented further by some special provision of fats; in Mediterranean conditions by olives and oil, involving extensive tree culture; in the forest region by pig's meat; and on the Atlantic seaboard by butter and beef.

At what places, and by the action of what liquids, are fats, proteids, and starch digested? What enzymes are found in the pancreatic juice? What is the digestive action of each? Describe the work performed by the muscles of the stomach, the mouth, the esophagus, and the small intestine. What advantages are derived from the use of cooked food? State the advantages of drinking pure water.

Shake well, and keep the tube in a water-bath at about 100 degrees F. A very good emulsion is obtained. Experiment 80. To show that bile favors filtration and the absorption of fats. Place two small funnels of exactly the same size in a filter stand, and under each a beaker. Pour into each an equal volume of almond oil; cover with a slip of glass to prevent evaporation.
