【单选题】

Fried foods have long been frowned upon. Nevertheless, the skillet(长柄平底煎锅) is about our handiest and most useful piece of kitchen equipment. Strong woodcutters and others engaged in active labor requiring 4,000 calories per day or more will take approximately one-third of their rations prepared in this fashion. Meat, eggs, and French toast cooked in this way are served in millions of homes daily. Apparently the consumers are not beset with more signs of indigestion than afflicted by those who insist upon broiling, roasting, or boiling. Some years ago one of our most eminent physiologists investigated the digestibility of fried potatoes. He found that the pan variety was more easily broken down for assimilation than when deep fat was employed. The latter, however, dissolved within the alimentary, tract(消化道) more readily than the boiled type. Furthermore, be learned, by watching the progress of the contents of the stomach by means of the fluoroscope(荧光检查仪), that fat actually accelerated the rate of digestion. Now all this is quite in contrast with "authority". Volumes have been written on nutrition, and everywhere the dictum(权威意见) has been accepted—no fried edibles of any sort for children. A few will go so far as to forbid this style of cooking wholly. Now and then an expert will be bold enough to admit that he uses them himself, the absence of discomfort being explained on the ground that he possesses a powerful gastric(胃的) apparatus. We can of course sizzle perfectly good articles to death so that they will be leathery and tough. But thorough heating, in the presence of shortening, is not the awful crime that it has been labeled. Such dishes stimulate rather than retard contractions of the gall bladder. Thus it is that bile(胆汁) mixes with the nutriment shortly after it leaves the stomach.
We don’t need to allow our foodstuffs to become oil soaked, but other than that, there seems to be no basis for the widely heralded prohibition against this method. But notions become fixed. The first condemnation probably rose because an "oracle"(圣贤) suffered from dyspepsia(消化不良) which he ascribed to some fried item on the menu. The theory spread. Others agreed with him, and after a time the doctrine became incorporated in our textbooks. The belief is now tradition rather than proved fact. It should have been refuted long since, as experience has demonstrated its falsity.

A.
