Most raw food, like our bodies, is very perishable. When raw foods are exposed to temperatures above 118 degrees, they start to rapidly break down, just as our bodies would if we had a fever that high. One of the constituents of foods which can break down are enzymes. Enzymes help us digest our food. Enzymes are proteins though, and they have a very specific 3-dimensional structure in space. Once they are heated much above 118 degrees, this structure can change. Once enzymes are exposed to heat, they are no longer able to provide the function for which they were designed. Cooked foods contribute to chronic illness, because their enzyme content is damaged and thus requires us to make our own enzymes to process the food. The digestion of cooked food uses valuable metabolic enzymes in order to help digest your food. Digestion of cooked food demands much more energy than the digestion of raw food. In general, raw food is so much more easily digested that it passes through the digestive tract in 1/2 to 1/3 of the time it takes for cooked food.
Eating enzyme-dead foods places a burden on your pancreas and other organs and overworks them, which eventually exhausts these organs. Many people gradually impair their pancreas and progressively lose the ability to digest their food after a lifetime of ingesting processed foods.
But you certainly can steam and blanch foods if you want your food at least warm. Use a food thermometer and cook them no higher than 118 degrees Fahrenheit. Up to this temperature, you won't be doing too much damage to the enzymes in food.
Are you interested in a raw food diet, but don't think you can do it all the time? You don't have to, certainly not to start. Many of us are conditioned to think of food as reward and comfort. We look forward to the end of the day, having dinner with our families, or going out to dinner with friends.
Try eating raw foods throughout the day. If you go to work every day, take carrots, apples, grapes or dried fruit with you to munch on. If you usually go out to lunch during the day, try to go places where you can get a salad. If you pack a lunch, include sprouts and fruit with it. Steamed brown rice and vegetables and a little fruit might not sound very interesting, but it's a good energy lunch. If you're like many people, those fast food lunches make you want to crawl under your desk and take a nap in the afternoon! They make you sluggish and tired. A lighter lunch of raw foods can keep you energized throughout the day.
The business culture is different these days, and there's less of a routine than there used to be with a morning "coffee break" and then "lunch hour" and an afternoon "break." That routine doesn't work for a lot of people any more, but you can still get hungry during the day. By taking a variety of raw foods with you to work, you can munch periodically during the day. Sometimes it's better to eat to avoid getting hungry. If we let ourselves go too long until we get ravenous, that's when it's easier to make poor food choices. Eating raw foods periodically throughout the day also keeps your metabolism humming along, and keeps your blood sugar at steady levels.
