Your Gut Bacteria Want You to Eat a Cupcake
Joyce Park stashed this in Science
Tell your doctor that your microbiome made you do it! They used DRUGS to prod and reward you into eating the foods they like.
They did! Bad gut bacteria! I was the victim!!
this is so true. it is not our fault. but now we need to use the force and tell them we won't obey!!
This has the makings of a great Pixar movie.
They could do it Fantastic Voyage style where humans shrink down to go confront the biome.
yes, and then a cute one becomes a pet that they having trouble letting go of by the end.
Oh I like that! They could have a sad goodbye scene near the end -- those always get to me!
and pixar loves those... :)
omg! i cried like a baby! and the very last scene when they say goodbye to andy?!!
Oh right! I'm tearing up just thinking about it.
My gut bacteria are controlling me!
Humans’ gastrointestinal tracts are home to 10,000 species of bacteria, which get energy from our half-digested lunches. (Another estimate puts the number of species as high as 36,000.) In exchange, they help us break down food and keep harmful bacteria out, and have also been shown to help regulate fat storage andprovide vitamins.
But a recent review published in BioEssays suggests that these bacteria might be a little too big for their britches, bossing their hosts around and demanding certain kinds of foods. “Microbial genes outnumber human genes by 100 to 1 in the intestinal microbiome,” the article says, so the microbes are winning the numbers game at least. But it’s not like they’re all on the same team. The authors (who hail from the University of New Mexico and the University of California, San Francisco) note that many different species compete for space and nutrients in our intestines, and the more dominant ones may have more influence on their humans.
They may do this by inducing cravings: “Individuals who are “chocolate desiring” have different microbial metabolites in their urine than “chocolate indifferent” individuals, despite eating identical diets,” the study says. Or, they may influence people’s moods—crying in infants with colic has been linked to changes in the gut microbiome. And one thing parents do to stop their babies’ crying is feed them.
The article suggests some potential mechanisms by which the bacterias exert their influence: They may change the expression of taste receptors, making certain foods taste better; they may release hunger-inducing hormones; or they may manipulate the vagus nerve (which connects the stomach to the brain) to control their hosts’ eating behavior.
And different bacteria want people to eat different things—some crave sugar, some crave fat. Some microbes found in people in Japan are especially good at digesting seaweed.
