One of the ex-directors of the FDA (Kessler) has written a book titled "The end of overeating".He appeared on CNN and made a few statemrnts about the obesity crisis.He said that the food industry add substabces to food that we get hooked on eating and related this to the amount of chewing.He said that long time the average amount of chewing prior to swallowing was about 60,but in modern times with the new food technologies,the average is about 4,so more food can be eaten.He went on to say that the idea behind the pre-cooked,abundance of sugar,salt,fat,and other additives are meant to keep us constantly stimulated while ignoring nutritional value. This would seem to imply that the degree of chewability is related to the extent of satiation and the role of peripheral factors in appetitive behavior. Now,as the only creative and divergent thinker on Tips,I am thinking of those rat pellets that were fed to rats.They were easily chewable.Have there been studies manipulating the chewability index of rat food and postulating the consequent effects on behavior? Send me something. Michael Sylvester,PhD Daytona Beach,Florida
