In his latest study, James Perfield, assistant professor of food science in the College of Agriculture, Food and Natural Resources (CAFNR), found that a specific plant oil, known as sterculic oil, may be a key in the fight against obesity. Sterculic oil is extracted from seeds of the Sterculia foetida tree.
To study the compound, Perfield added sterculic oil to the feed of rats that are genetically disposed to have a high amount of abdominal fat. He tested the rats over the course of 13 weeks and found that rats given a diet supplemented with sterulic oil had less abdominal fat and a decreased likelihood of developing diabetes. Perfield gave the rats a relatively small dose of oil each day, comparable to giving three grams to a 250-pound human.
Belly fat, clinically known as intra-abdominal fat, is between internal organs and the torso. Intra-abdominal fat is composed of "adipose" deposits. Unusually high adipose levels trigger health problems that may induce insulin resistance, which causes the body to have difficulty maintaining blood sugar levels. Initially, the body is able to compensate by producing more insulin, but eventually the pancreas is unable to produce enough insulin, thus increasing excess sugar in the bloodstream and setting the stage for diabetes, cardiovascular disease and other obesity-associated health disorders.
Perfield plans to conduct further studies of sterulic oil in hopes of developing a natural nutritional supplement. He says future research will focus on the effectiveness of the oil in humans, as well as any side effects.
"The oil from this seed is very similar to other vegetable oils," Perfield said. "It shares many of the same chemical properties, which could allow it to be easily substituted with other oils. While eating the seed directly may be possible, it's easier to control the amount of oil if you extract it directly."
Perfield presented the research at the Diabetes, Insulin Resistance and Metabolic Dysfunction Symposium in Keystone, Colo. The research was funded by the Diabetes Action Research and Education Foundation, MU Food for the 21st Century, and CAFNR.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
