Sugar can make you a sweeter person  

i read an article which was from Amsterdam University and Florida State University that sugar can make you a sweeter person. its a saying also but i never read a research that claims it. today when i read it, i wanted to discuss it with all of you on mylot and wanna know your views on it.
to reach the conclusion , the researchers gave a group of people some with sugar and some with an artificial sweetner. they were then shown a picture of Sammy, a young man said to be gay, and asked to write about 5 minutes about his typical day.
those who had drunk the sugary drink used far fewer stereotypes in their essays than those who had the artificial sweetner. leading to a theory that people who can restraint to keep objectionable thoughts to themselves when they have higher amounts of glucose in their body.
people with lower glucose levels are more likely to use stereotypes when describing others and if they are high in prejudice , are more likely to make derogatory remarks.
this is because self control depends on processes that consume glucose as an energy source , people who have lower levels of blood glucose may be more likely to express prejudice.
so what do you people think about it?
