The power of the gut

There’s a short article at Physorg about research into the relation between gut bacteria and the brain (and thereby personality, mental illness, etc.)

Using germ-free mice, Foster's research shows gut bacteria influences how the brain is wired for learning and memory. The research paper has been published in the March issue of the science journal Neurogastroenterology and Motility.

The study's results show that genes linked to learning and memory are altered in germ-free mice and, in particular, they are altered in one of the key brain regions for learning and memory – the hippocampus.

"The take-home message is that gut bacteria influences anxiety-like behavior through alterations in the way the brain is wired," said Foster.

Foster's laboratory is located in the Brain-Body Institute, a joint research initiative of McMaster University and St. Joseph's Healthcare in Hamilton. The institute was created to advance understanding of the relationship between the brain, nervous system and bodily disorders.

"We have a hypothesis in my lab that the state of your immune system and your gut bacteria – which are in constant communication – influences your personality," Foster said.

I can’t help but think of Hitler, who had serious digestive problems all his life. This is from an interesting review of a book on the topic of his health:

Theo Morell, recorded in his diary that after Hitler downed a typical vegetable platter, "constipation and colossal flatulence occurred on a scale I have seldom encountered before."….

Morell's diaries (which were recovered from Germany and are kept in the National Archives in Washington, DC) make clear that the bouts of "agonizing flatulence" remained a regular occurrence.

Although I have noted in a previous post the cocaine eyedrops and methamphetamine that Hitler’s quack doctor Morell prescribed, I am not sure if I read this before:

Morell plied him with a remedy called "Dr. Küster's Anti-gas pills," which contained significant amounts of strychnine--and Hitler often took as many as 16 of the little black pills a day. The sallow skin, glaucous eyes and attention lapses noted by observers later in the war are consistent with strychnine poisoning; another ingredient in the pills, antropine, causes mood wings from euphoria to violent anger.

I see that someone on Yahoo Answers has asked whether Adolf might have suffered from celiac disease (the intolerance to gluten that seemingly has risen sharply – at least in diagnosis – lately.) This seems a pretty good suggestion, actually, especially if (as one person in the answers notes) he was “notoriously fond of cakes and pastries.” I see a source for that is Mental Floss Magazine ( a journal that has escaped my attention til now) blog which says:

In fact, Hitler’s favorite dessert chef, Gerhardt Shtammer, claims that Hitler asked him to make delectable desserts right up to the very end, when they were trapped in Hitler’s bunker with hard-core Nazi holdouts. According to Shtammer, Hitler’s favorite desserts were eclairs decorated with little swastikas and strudel.

Googling "Gerhardt Shtammer" does not come up with any more detail, though. If he lived today, he would have had appearances on Oprah, at the very least.

So, there you go. We can add “cream puffs” to our list of speculations as to the cause of World War II.
