Fatty foods fight inflammation

10.10.2005


"Take two cheeseburgers and call me in the morning," may sound like far-fetched medical advice. After all, high fat foods can worsen blockages in blood vessels. But a new study in the October 17 issue of The Journal of Experimental Medicine shows that high fat foods can, at least in the gut, soothe inflammation. This action may stop immune cells from attacking food as a foreign invader.



Eating -- particularly eating fat-rich foods -- causes cells in the small intestine to produce a hormone called cholecystokinin, or CCK. CCK stimulates digestion and gut peristalsis (the motion that propels food along the digestive tract), and also triggers satiation -- the full feeling that prompts you to stop eating.

The study by Luyer and colleagues shows that fat-induced CCK can also dampen inflammation in the gut, as rats fed a high-fat diet were protected against lethal bacteria-induced shock whereas those fed a low-fat diet were not. CCK sent signals to the brain through the vagus nerve, the nerve that provides the electrical regulation for many internal organs, including the gut and the heart. In response to CCK, vagus nerve endings in the gut released a neurotransmitter called acetylcholine. Acetylcholine then bound to proteins on immune cells and turned the cells off.


The authors think this pathway might explain why the immune system doesn’t react to food proteins and normal gut bacteria as if they were foreign invaders. They also suggest that triggering this fat-driven chain of events in patients might provide a way to reduce inflammatory complications after surgery.

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

Im Focus: Computer-Designed Customized Regenerative Heart Valves

Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.

Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
