Study: Too Much Sugar Makes You Dumb

Eating too much sugar can eat away at your brainpower, according to US scientists who published a study Tuesday showing how a steady diet of high-fructose corn syrup sapped lab rats’ memories.

Researchers at the University of California Los Angeles (UCLA) fed two groups of rats a solution containing high-fructose corn syrup — a common ingredient in processed foods – as drinking water for six weeks. One group of rats was supplemented with brain-boosting omega-3 fatty acids in the form of flaxseed oil and docosahexaenoic acid (DHA), while the other group was not.

“The DHA-deprived animals were slower, and their brains showed a decline in synaptic activity,” said Fernando Gomez-Pinilla, a professor of neurosurgery at the David Geffen School of Medicine at UCLA. ”Their brain cells had trouble signaling each other, disrupting the rats’ ability to think clearly and recall the route they’d learned six weeks earlier.”


A closer look at the rat brains revealed that those who were not fed DHA supplements had also developed signs of resistance to insulin, a hormone that controls blood sugar and regulates brain function. In other words, eating too much fructose could interfere with insulin’s ability to regulate how cells use and store sugar, which is necessary for processing thoughts and emotions. High-fructose corn syrup is commonly found in soda, condiments, applesauce, baby food and other processed snacks.

While the study did not say what the equivalent might be for a human to consume as much high-fructose corn syrup as the rats did, researchers said it provides some evidence that metabolic syndrome can affect the mind as well as the body. The study appeared in the Journal of Physiology.

Child Psychopaths — Are They Real?

The groundbreaking HBO documentary “Child of Rage” years ago showed how horrific abuse and neglect could turn a child into a psychopath. But what about the kids who aren’t abused? What about the ones who, for no discernible reason, do horrible things to other people?

Experts are divided about whether it’s right to label a child as a psychopath. On the one hand, their brains are still developing; since psychopathy is largely considered untreatable, such a label would carry a heavy, life-altering stigma. On the other hand, identifying “callous-unemotional” children early could allow for successful treatment — or at least a heads-up to society.

But reaching such a diagnosis can be tricky. Certain tendencies, like narcissism and impulsiveness, that are obvious signs of a psychopath are also part and parcel of childhood. And callous-unemotional kids are often extremely intelligent; they’re able to lie and manipulate without remorse, making it harder to understand what they’re doing and why.


In “Child of Rage,” 6-year-old Beth opens her blue eyes wide and calmly tells her psychiatrist how she’d like to hurt, and even kill, her adoptive parents — a Baptist preacher and his wife — and her biological brother. She’s calm and conversational as she describes how she has deliberately harmed and killed animals, how she drives pins into her brother and sexually molests him, how she repeatedly slammed his head into a cement floor and only stopped because someone caught her.

Beth suffered extreme physical and sexual abuse and neglect by her biological parents, which experts say could explain her detached, calculating demeanor and her lack of “a sense of conscience.” But some other “kid psychopaths” seem to have grown up surrounded by love and affection.

Some experts say that psychopathy, like other mental illnesses, may have a genetic component; others think that it is a neurological condition all its own, like autism is, though it’s not part of the autism spectrum. Though some psychologists believe one can start seeing psychopathic traits as early as age 5, there is not yet a definitive test for children that young.

In your opinion, is it nature or nurture that pushes a child to become a psychopath? Voice out!
