Olive Oil may Help Tackle Hunger Pangs

 Olive Oil may Help Tackle Hunger Pangs
Researchers are reporting that a healthy fat found in olive oil, nuts and avocados is important in send message of fullness to the brain. In effect it tells the brain to stop eating.

The study by UC Irvine pharmacologists shows that these fats trigger production of a compound in the small intestine that curbs hunger pangs.

The discovery, the researchers say, points toward new approaches to treating obesity and other eating disorders.

Daniele Piomelli, the Louise Turner Arnold Chair in Neurosciences, and his colleagues have studied how a fat-derived compound called oleoylethanolamide regulates hunger and body weight.

The study has been published in the journal Cell Metabolism.

The analysis revealed that an unsaturated fatty acid called oleic acid stimulates production of OEA, which in turn decreases appetite.

Oleic acid is transformed into OEA by cells in the upper region of the small intestine. OEA then finds its way to nerve endings that carry the hunger-curbing message to the brain.

There, it activates a brain circuit that increases feelings of fullness. In previous studies, Piomelli found that increasing OEA levels can reduce appetite, produce weight loss and lower blood cholesterol and triglyceride levels.

Piomelli believes OEA could be used in a variety of drugs because it is a key to the way the body naturally handles fatty foods and regulates eating and body weight.

"We are excited to find that OEA activates cell receptors that already have been the focus of successful drug development," he said.

"This gives us hope for a new class of anti-obesity drugs based on the savvy use of natural appetite-controlling mechanisms," the expert added.
