Could Trans Fats Make You Cranky?

THURSDAY, March 15 (HealthDay News) — Eating a diet high in
trans fatty acids, an ingredient found in fried foods, baked goods and
other prepared meals and snacks, might be associated with negative — and
even aggressive — behavior, new research suggests.

In conducting the study, researchers from the University of California,
San Diego School of Medicine analyzed the diet and behavior of 945 men and
women. They also considered other possible contributing factors, such as
the participants’ history of aggression as well as alcohol and tobacco
use.

The study, published online recently in PLoS ONE, found that
people who consumed more trans fats were more likely to demonstrate
negative behaviors, such as impatience, irritability and aggression.

Study leader Dr. Beatrice Golomb, an associate professor in the UC San
Diego department of medicine, explained in a university news release that
higher levels of trans fatty acids in the diet were “significantly
associated with greater aggression, and were more consistently predictive
of aggression and irritability, across the measures tested, than the other
known aggression predictors that were assessed.”

However, while the study uncovered an association between dietary trans
fatty acids and negative behavior, it did not prove a cause-and-effect
relationship.

“If the association between trans fats and aggressive behavior proves
to be causal, this adds further rationale to recommendations to avoid
eating trans fats, or including them in foods provided at institutions
like schools and prisons, since the detrimental effects of trans fats may
extend beyond the person who consumes them to affect others,” Golomb
concluded in the news release.

“Dietary trans fatty acids are primarily products of hydrogenation, a
chemical process that makes [unsaturated] oils solid at room temperature,”
according to background information in the study. Previous research has
linked dietary trans fatty acids to adverse health effects on lipids (such
as cholesterol), metabolic function (how the body turns food into energy),
insulin resistance, inflammation and cardiac and general health, the
authors of the report noted.
