You Have Taste Receptors in Your Colon. Here’s Why.

Taste receptors don’t only exist in your mouth. You can find them all over your body, including your stomach, your lungs, and your colon. Why? It turns out the taste receptors are much more versatile tools than we suppose.

The flavors are so pronounced, you can just sense the aftertaste on the tip of your bum. But that might only be the spicy food…

Six Myths About Digestion That Just Won’t Die

Most of us have a vague idea of how digestion works: we eat food, break it down (that’s the scientific term, right?) and, somehow, profit. But without a better understanding of what goes on in there, we’re liable to believe a few bizarre myths that have become commonplace.

In reality, our digestive tract is a complex system with many parts that communicate with each other and the rest of our body. It’s also very adaptable to what we put in it, and doesn’t need specific food combinations or “cleanses” to keep working at its best. Here are some of the top myths about digestion, and the truths behind them.

How to Avoid the Dreaded “Carb Coma”

Carb-heavy meals are notorious for making you hungry and cranky later in the day, not to mention gaining weight. But if you really want to eat your pasta and potatoes, you can make the meal easier for your body to deal with by adding other food to it. Pancakes and bacon are a better bet than pancakes alone.

FDA Approves Implantable Vagus Nerve Disruptor For Weight Loss

The implants have been used to control certain forms of epilepsy for some time. The side effects are known, which is how the possible use for weight control was discovered.

In a bid to increase treatments for the nation’s 79 million obese adults, the Food and Drug Administration has approved U.S. marketing of an implantable device that stimulates weight loss by manipulating key appetite signals passing between the brain and the gut.

The new device is the Maestro Rechargeable System, manufactured by EnteroMedics of St. Paul, Minn. While the FDA has approved four medications for weight loss in the past 2 1/2 years, the Maestro system is the first weight loss device to be approved since 2007.

Over a year, on average, it increases the weight loss by “about 8.5%” compared to an implant which was turned off. And it worked for about half the people…  An overwhelming amount of the weight loss was attributable to factors other than the implant.

How Does Your Stomach Know When to Vomit?

There are several ways to induce vomiting in humans. Without getting too specific, they are all linked through the “vomiting center” of the brain, also known as the area postrema. The “vomiting center” is capable of responding to many different types of poisons, toxins, conditions, etc. In the case of eating something bad, remember that the stomach is a highly vascularized zone that also happens to have a massive nervous structure called the enteric nervous system.

Usually food poisoning that involves vomiting is caused by organisms that have preformed toxins, including but not limited to B cereus and S aureus. That delicious looking potato salad is teeming with toxins that have been pre-made by the bacterial species to wreak havoc on whomever might eat it. These toxins work within hours, causing inflammation in the gut.  This information gets relayed back to the vomiting center.  Once the brain registers that something is not right in your tummy, it stimulates muscles to close the pyloric sphincter (bottom of the stomach) and open the cardiac sphincter (top of the stomach) before activating the abdominal musculature and diaphragm to propel the harmful substance out of the stomach via forceful contraction.

What about a “strong” vs “weak” stomach?  A lot of why people throw up is mental – you have incredible subconscious control over puking.  Or it could have to do with innoculum – give someone a large enough dose of toxin/bacteria, and they’ll blow chunks.

The funny thing about it, you need your brains “permission” to puke, but your gut doesn’t need your brains permission for diarrhea.  If for some reason you ate something wacky that managed to get past the brain’s vomiting center detection, your intestines will flush with extreme prejudice.  Sometimes, a group of people who eat the same bad food can experience either symptom – vomit or diarrhea.

Can You Bust a Gut from Eating Too Much at Once?

In [the movie] Se7en an obese man is made to stuff himself until his stomach bursts. Is this really possible? Wouldn’t you just naturally throw up?

Although extremely rare, some people actually have ruptured their stomachs after eating too much, and, perhaps not surprisingly, many did not survive.

I was surprised to see Weekly World News quoted.  I’d dismiss that paragraph entirely.
