A molecular pathway activated in the brain during fasting helps halt the spread of GI bacteria into the bloodstream, according to a new study researchers at the Salk Institute. A molecular pathway by which the brain communicates with the GIT prevents unnecessary activation of the immune system during fasting by strengthening the barrier against gut microbes...

Don’t have room for dessert? The bacteria in your gut may be telling you something. 20 min after a meal, gut microbes produce proteins that can suppress food intake in animals, reports a study. The researchers also show how these proteins injected into mice and rats act on the brain reducing appetite, suggesting that gut bacteria may help control when and how much we eat.
The new evidence coexists with current models of appetite control, which involve hormones from the gut signalling to brain circuits when we’re hu...

Read MorePeople fed beta-glucan-enriched pasta for 2 months showed increased populations of beneficial bacteria in their intestinal tracts, and reduced populations of non-beneficial bacteria. They also showed reduced LDL (bad) cholesterol. This work is part of a broad effort to identify potential prebiotics – foods that could encourage the growth of health-promoting bacteria in the gastrointestinal tract.
β-glucans are healthy fibers that humans cannot digest, but that can be digested by some species of our gut bacteria. They are special types of sugars that are found in the cell walls of certain microbes, as well as in oats and barley...
