Study reveals a novel learning process orchestrated between the digestive system and brain that compels animals to seek out novel foods.
Researchers say the sight and smell of food alone may be enough to prompt the liver to start the processes that help digest food.
Researchers reveal the Western diet can induce the expansion of microbes in the small intestine that promote the digestion and absorption of high fat foods. Over time, researchers say, these microbes can increase the risk of obesity.
According to researchers, modern primates, including humans, are still able to digest insects as well as our ancestors did. The CHIA gene allows us to digest an insect's exoskeleton, researchers report.
A new study investigates how digestive problems and anxiety may be linked.
