...Mutton, pork, ham, and even venison all dance to the same music. Spinach, turnip-tops and other greens were boiled and baptized with grease. It was hog meat, hog meat everywhere; hog meat for breakfast, hog meat for dinner, hog meat for supper, always fried and served up in its own grease. A caustic observer says that the devil of indigestion holds full sway in certain localities because the frying-pan has a firm grip on the affections of the people. He complains of seeing tall, gaunt men, sallow faces like corpses, having perfect satisfaction with the country, a lack of strong high ambition; women, gaunt, haggard, and hopeless looking, all trace of womanly beauty long since gone, every line of their faces speaking of want, privation, neglect of all sanitary laws, and unvaried monotony of unwholesome food; little children, flabby, yellow, pallid, with old men's faces. This is not malaria, he says, but the frying-pan.--From Good Housekeeping--
To avoid fried foods is something your great-grandmother might have told you. Granted, she might have said it would make you waste away, but then people have been sure their food was killing them for some time.
