 Decision-making Abilities may be Affected by Fluctuating Blood Glucose Levels
A new American study has revealed that decision-making abilities may be affected by fluctuating Blood glucose levels.

Psychological scientists X.T. Wang and Robert D. Dvorak from the University of South Dakota looked into how blood glucose levels affect our thinking about present and future rewards.

Participants in the study answered a series of questions asking if they would prefer to receive a certain amount of money tomorrow or a larger amount of money at a later date. The subjects answered seven of these questions before and after drinking either a regular soda that contained containing sugar or a diet soda, which contained the artificial sweetener aspartame. Blood glucose levels were measured at the beginning of the experiment and after the participants drank the soda.

It was seen that blood glucose levels might influence people's preferences for current versus later rewards. The volunteers who drank the regular sodas and thus had higher blood glucose levels were more likely to select receiving more money at a later date, while those who had diet sodas and had lower blood glucose levels were likely to opt for receiving smaller sums of money immediately.
