Think what you eat: Studies point to cellular factors linking diet and behavior
Date:10/20/2009

New research released today is affirming a long-held maxim: you are what you eat and, more to the point, what you eat has a profound influence on the brain. The findings offer insight into the neurobiological factors behind the obesity epidemic in the United States and other developed countries. The findings exposed changes in brain chemistry due to diet and weight gain, and were reported at Neuroscience 2009, the Society for Neuroscience's annual meeting and the world's largest source of emerging news about brain science and health.

Obesity has been linked to rises in diabetes, stroke, and heart attacks, among other disorders. In the past decade alone, medical spending for obesity is estimated to have increased 87 percent in the United States reaching $147 billion in 2008 according to a study funded by the Centers for Disease Control and Prevention. The new research adds another dimension to understanding how obesity rates have more than doubled in the past 30 years.

The new findings show that:

  • Disruptions in the sleep/wake cycle lead to weight gain, impulsivity, slower thinking, and other physiological and behavioral changes. These findings may be particularly important for people who do shift work (Ilia Karatsoreos, PhD, abstract 471.1, see attached summary).

  • Pregnant mice fed a high-fat diet produced pups that were longer, weighed more, and had reduced insulin sensitivity factors that indicate a predisposition toward obesity and diabetes. In addition, despite no further exposure to a high-fat diet, these pups passed on those same traits to their offspring (Tracy Bale, PhD, abstract 666.21, see attached summary).

  • Feeding high-fat food to pregnant mice can affect the brain development of their offspring, causing the pups to be more vulnerable to obesity and to engaging in addictive-like behaviors in adulthood (Teresa Reyes, PhD, abstract 87.1, see attached summary).
