It is believed that the sugar rush provides the brain with the fuel it needs to push away thoughts of blame and revenge, making it easier for us to forgive and forget.
“These findings provide the first evidence that forgiveness depends on how efficiently the body uses glucose,” the Daily Mail quoted researchers at the University of Kentucky as saying.
The researchers team looked at whether there was a link between symptoms of the most common type of diabetes and the ability to forgive.
Type 2 diabetes is linked to obesity and usually develops in middle age. Sufferers struggle to turn glucose, or sugar, into energy needed to fuel the brain.
