In an interesting twist for the anti-sugar movement, new research shows decreased blood glucose levels correlate with increased aggressive behaviour toward your partner.
Researchers from Ohio State University analysed daily blood glucose in 107 heterosexual married couples over a period of 21 days and discovered a clear correlation between decreased blood glucose levels and increased aggressive behaviour.
They found low glucose levels predicted higher aggressive impulses in the form of stabbing pins in a voodoo doll that represented a spouse and “louder unpleasant noise blasts” for longer durations to a spouse.
Moreover, the findings remained significant even after controlling for “relationship satisfaction and participant sex”.
The researchers concluded that self-control requires a lot of brain food in the form of glucose, and the healthy metabolism of glucose may contribute to more peaceful homes by providing couples a boost to their self-control energy.
