food canal

[AntonioLao]

The food canal is a long tube that begins at the mouth goes thru the body and terminates at the anus. For a fully developed healthy adult human being, it is about 30 feet long that is twisted, folded, and coiled around itself in order to fit inside the body. It has wide sections and narrow sections and every section has a particular digestive function.

To begin, the salivary glands in the cheeks or under the tongue secrete a starch-splitting enzyme called salivary amylase and start the process of digestion. The partially digested food passed thru the esophagus into the stomach. The stomach is the largest section of the food canal. Its muscular walls squeeze and mix the food with gastric hydrochloric acid, strongest acid in the body with pH of 3 or lower. This acid speeds up hydrolysis and helps the protein-splitting enzyme pepsin. Next, the food enters the small intestine where serious digestion takes place. The small intestine is about 20 feet long. At its entrance are two large glands: the liver and the pancreas. The pancreas secretes protein-splitting enzymes called trypsin, fat-splitting lipase, starch-splitting amylase, and other digestive enzymes. For the lipase to speed up fats digestion, it needs the help of the liver’s secretions called bile which is not an enzyme but can dissolve fat in water. Finally, the large intestine disposed the almost completely dehydrated undigestible waste.

By sheer coincidence or not, the length of the food canal is equivalent to the length of sea level gravitational acceleration of 32 feet per second per second. This implies that the healthy eating speed limit going for second serving just takes a second. Breaking this limit has serious consequences. Too slow or too fast would both cause gastric indigestion. Forming a habit of obeying this eating speed limit would definitely boost one’s intelligence as well as one’s physical fitness.

I fail to see a relationship between the two?

Eating too much, too fast, or in poor combinations, may all cause gastric indigestion. Wheat, corn, dairy, and peanuts are just some common allergens that may mimic gastric indigestion or cause other bowel disorder.

An eating speed limit?

How about......'All you can eat buffet! Rules of food combining and blood type must be observed when making your selections. NO FOOD TO BE WASTED! You can refill your plate as many times as you wish in the time allowed. Time limit 5 minutes.' (Seniors, infants, and those requiring assisted eating, 15 minutes.)

I think the missing connection is the heart beat which for human is little bits more than 1 beat per second. For each beat we can then associate it with a distance of about 30 feet and rate can be defined as distance per unit of time.
