Undigested Red Meat

Just the other decade I was watching a movie in which a character stated that the average male has four pounds of undigested red meat in his bowels at all times. Now this got me thinking. Why is the meat undigested? And why does the body set aside four pounds of it not to digest? How does it keep it fresh? Is it stored in a special meat sack for emergencies, like when your significant other goes on a weird vegetarian diet and you end up eating dinners consisting of bean sprouts on a bed of sawdust and carbon nanotubles? I think I'll have to send an e-mail to P.Z. Myers, the biologist. He's an expert on squids and pirates, so if anyone could explain the mysteries of the meat sack to me it would be him.

Of course, Australian researchers have long known about the existence of the carrot sack, which can store carrots for years after you've eaten them.

I think the movie was making it up. It's just not true.

What it may refer to is that we all carry 2-5 pounds of bacteria in our guts. Those bacteria have multiple functions and are essential for normal digestion -- "Montezuma's revenge" is what happens when foreign bacteria displace our normal happy colony.

Correction: the average 50 year old meat-eating person - male or female - has up to 8 pounds of undigestable meat in their bowels. This decaying "flesh" or meat as people like to think of it, is the common cause of what many people think of as the "price of living" - colon and pancreatic cancers by the age of 50-60.

Think about what a surgeon tells a heart bypass survivor "cut out the meat in your diet, eat more fruits and vegetables". I say, "why wait until you have to go under the surgeon's knife, start now."

I don't see why you have to ridicule someone for being vegetarian in order to ask a question like that. For someone as clearly intelligent as yourself, it seems uncharacteristic to create a caricature of some other diet simply because you don't practice it yourself. I don't describe meat eaters as being on "some weird ravenous flesh based diet". It would be misleading and a straw-man to do so.

Otherwise, keep up the great work. This is a great blog
