Chemical reactions typically double in speed with every 10 degrees C. increase in temperature. So oil goes rancid about six times faster at normal room temperature than it does in the fridge. If you'll think about the implications of this data you'll see there are two powerful reasons not to fry food. One, the food is coated with oil and gains in satiety value at the expense of becoming relatively indigestible and productive of toxemia. Secondly, if frying occurs at 150 degrees Centigrade and normal room temperature is 20 degrees Centigrade, then oil goes rancid 2 to the 13th power faster in the frying pan, or about 8,200 times faster. Heating oil for only ten minutes in a hot skillet induces as much rancidity as about 6 weeks of sitting open and exposed to air at room temperature. Think about that the next time you're tempted to eat something from a fast food restaurant where the hot fat in the deep fryer has been reacting with oxygen all day, or even for several days. Back to butter, where we started. If you must have something traditionally northern European on your bread, you are far better off to use butter, not margarine. However, Mediterranean peoples traditionally dip their bread in high-quality extra-virgin olive oil that smells and tastes like olives. Its delicious, why not try it. But best yet, put low-sugar fruit preserves on your toast or develop a taste for dry toast. Probably the finest use for butter is melted over steamed vegetables. This way only small quantities are needed and the fat goes on something that is otherwise very easy to digest so its presence will not produce as many toxins in the digestive tract. Milk, Meat, And Other Protein Foods Speaking of butter, how about milk? The dairy lobby is very powerful in North America. Its political clout and campaign contributions have the governments of both the United States and especially that of Canada eating out of its hand (literally), providing the dairy industry with price supports. Because of these price supports, in Canada cheese costs half again more than it does in the United States. The dairy lobby is also very cozy with the medical profession so licensed nutritionists constantly bombard us with "drink milk" and "cheese is good for you" propaganda.
