Study Finds High Fructose Intake May Trigger Impulsive Behavior, Aggression, and ADHD

ADHD blog 12012021Science Times [1] reported a study conducted by the University of Colorado Anschutz Medical Campus, the University of Denver, and New England Inpatient Specialists that was recently published in the journal Evolution and Human Behavior.

According to Science Times, “The study by the researchers hypothesized that hyperactive disorders such as impulsivity and mania go back to ancient foraging instincts triggered by a high intake of fructose.

The researchers warn that consuming large amounts of fructose stimulates craving, impulsivity, risk-taking, and aggression that increases the risk for ADHD, bipolar disease and aggressive behavior."

The researchers also note that the after effects of fructose metabolism may also stimulate pathways that trigger depression and "desensitization of hedonic responses."

In an interview, Richard Johnson from the University of Colorado Anschutz Medical Campus said, "Behavioral Disorders are common and are associated with obesity and western diet." Excessive intake of fructose in the form of high fructose corn syrup and refined sugars may largely contribute to these conditions.

Fructose triggers a response similar to starvation since it lowers the energy in cells, explained the team. The foraging response stimulates high-risk behaviors such as impulsivity and aggression as a survival response to securing food. Moreover, overactivation of this behavior leads to conditions such as ADHD and bipolar disorder.”

The aforementioned research echoes previous research regarding the effects of high fructose sugars and the western diet in general. Limiting sugar intake, reducing high fat intake, and exercising are often recommended as elements of a healthy lifestyle.
