The sugar myth

The researchers from the University of Warwick, Humboldt University of Berlin and Lancaster University, examined literature from 31 previous studies on the subject and additionally employed the service of 1, 259 participants to determine more concretely the impact sugar has on anger, alertness, depression, and fatigue.  The individuals examined were tasked with demanding physical and mental activity to see if their performance faired any better or worse after sugar consumption.

Dr. Konstantinos Mantantzis, the study’s other lead author, said of the purported rush of energy furthered significantly by “pop culture” that it’s nothing more than a myth. The team’s data could not substantiate anything resembling a boost to cognitive or emotional performance. “If anything, sugar will probably make you feel worse,” says Mantantzis.

A mere hour after imbibing sugar, the participants of the study were found to be more likely to feel tuckered out.

This data comes on the back of a sobering new study published in The Lancet about the surging mortality rates informed by our unhealthy diets. One of the dietary risk factors contributing to the 11 million early deaths statics mentioned in the Lancet study is sugary beverages, the consumption. of which fattens cancer deaths and cardiovascular-related deaths annually.
