Horace Fletcher, whose name has become synonymous with the importance of chewing food well (Fletcherizing), ran an experiment on a military population in Canada. He required half his experimental group to chew thoroughly, and the other half to gulp things down as usual. His study reports significant improvement in the overall health and performance of the group that persistently chewed. Fletcher's report recommended that every mouthful be chewed 50 times for half a minute before being swallowed. Try it, you might be very surprised at what a beneficial effect such a simple change in your approach to eating can make. Not only will you have less intestinal gas, if overweight you will probably find yourself getting smaller because your blood sugar will elevate quicker as you are eating and thus your sense of hunger will go away sooner. If you are very thin and have difficulty gaining weight you may find that the pounds go on easier because chewing well makes your body more capable of actually assimilating the calories you are consuming. A logical conclusion from this data is that anything that would prevent or reduce chewing would be unhealthful. For example, food eaten when too hot tends to be gulped down. The same tends to happen when food is seasoned with fresh Jalapeno or habaneo peppers. People with poor teeth should blend or mash starchy foods and then gum them thoroughly to mix them with saliva. Keep in mind that even so-called protein foods such as beans often contain large quantities of starches and the starch portion of protein foods is also digested in the mouth. Once the food is in the stomach, it is mixed with hydrochloric acid, secreted by the stomach itself, and pepsin, an enzyme. Together these break proteins down into water-soluble amino acids. To accomplish this the stomach muscles agitate the food continuously, somewhat like a washing machine. This extended churning forms a kind of ball in the stomach called a bolis. Many things can and frequently do go wrong at this stage of the digestive process. First, the stomach's very acid environment inactivates pylatin, so any starch not converted to sugar in the mouth does not get properly processed thereafter. And the most dangerous misdigetion comes from the sad fact that cooked proteins are relatively indigestible no matter how strong the constitution, no matter how concentrated the stomach acid or how many enzymes present. It is quite understandable to me that people do not wish to accept this fact. After all, cooked proteins are so delicious, especially cooked red meats and the harder, more flavorful fishes.
