‘Sugar Rush’ a Myth, Actually Worsens Mood
Sugar does not improve mood and it can make people less alert and more tired after its consumption, according to a new study by the University of Warwick, Humboldt University of Berlin, and Lancaster University.
Using data collected from 31 published studies involving almost 1300 adults, Dr Konstantinos Mantantzis at Humboldt University of Berlin, Dr Sandra Sünram-Lea at Lancaster University, and Dr Friederike Schlaghecken and Professor Elizabeth Maylor in the University of Warwick’s Department of Psychology investigated the effect of sugar on various aspects of mood, including anger, alertness, depression, and fatigue.
They also considered how factors such as the quantity and type of sugar consumed might affect mood, and whether engaging in demanding mental and physical activities made any difference.
The researchers found that :
- Sugar consumption has virtually no effect on mood, regardless of how much sugar is consumed or whether people engage in demanding activities after taking it.
- People who consumed sugar felt more tired and less alert than those who had not.
- The idea of a ‘sugar rush’ is a myth without any truth behind it.
Professor Elizabeth Maylor, from the University of Warwick, commented: “We hope that our findings will go a long way to dispel the myth of the ‘sugar rush’ and inform public health policies to decrease sugar consumption.”
