Statistics do not bear out such fancies. Butter consumption has plummeted from 18 lb (8.165 kg) per person a year in 1900, to less than 5 lb (2.27 kg) per person a year today. Additionally, Westerners, urged on by government health agencies, have reduced their intake of eggs, cream, lard, and pork. Chicken consumption has risen in the past few decades, but chicken is lower in saturated fat than either beef or pork.
Furthermore, a survey of cookbooks published in America in the last century shows that people of earlier times ate plenty of animal foods and saturated fats. For example, in the Baptist Ladies Cook Book (Monmouth, Illinois, 1895), virtually every recipe calls for butter, cream or lard. Recipes for creamed vegetables are numerous as well. A scan of the Searchlight Recipe Book (Capper Publications, 1931) also has similar recipes: creamed liver, creamed cucumbers, hearts braised in buttermilk, etc. British Jews, as shown by the Jewish Housewives Cookbook (London, 1846), also had diets rich in cream, butter, eggs, and lamb and beef tallows. One recipe for German waffles, for example, calls for a dozen egg yolks and an entire pound of butter. A recipe for Oyster Pie from the Baptist cookbook calls for a quart of cream and a dozen eggs, and so forth and so on.
It does not appear, then, that people ate leaner diets in the last century. It is true that beef consumption has risen in the last few decades, but what has also risen precipitously, however, is consumption of margarine and other food products containing trans-fatty acids, lifeless, packaged "foods", processed vegetable oils, carbohydrates and refined sugar. Since one does not see chronic diseases like cancer and heart disease in beef-eating native peoples like the Maasai and Samburu, it is not possible for beef to be the culprit behind these modern epidemics. This, of course, points the finger squarely at the other dietary factors as the most likely causes.
