Lennerz, Belinda. Effects offects of dietary glycemic index on brain regions related to reward and craving in men.

Scientists examined the effects of the glycemic index on brain activity after eating a typical meal.  Twelve overweight men were gathered to consume two different milk shakes.  One milk shake had “rapidly digesting (high-glycemic) carbohydrates, and the other, slowly digesting(low-glycemic) carbohydrates. ”

The articles question was does high-glycemic food encourage overeating.  The research question was “is there a strong correlation between high-glycemic food and overeating, as oppose to a correlation between low-glycemic food and overeating.

The type of data would be aggregate.  The study requires retrieving numbers from observation.  The articles’ scientists retrieved their data by conducting MRIs upon 12 overweight men as they drank the two shakes.  The scientists observed the body-reactions after consuming the different shakes in relation to desire to consume more food.

After retrieval the data is analyzed by comparing the independent variables, the results from the different shakes, in terms of the dependent variable, the 12 overweight men being tested. By finding there was a stronger correlation between the high-glycemic food and overeating, than low-glycemic food and overeating.  After the participants drank the high-glycemic shake, they experienced a sudden burst in blood sugar levels, then a four hour period of low blood sugar levels.  During the period of low blood sugar levels, humans desire to consume more high-glycemic food to raise our blood sugar levels back to what they were before.

This is important research for people to educate themselves with when dieting.  It is better to consume foods with low-glycemic carbohydrates, because they are less likely to mess with your blood sugar levels.  Therefore, allowing you to have steady eating patterns throughout your diet.

This research also explains the body’s reaction to unhealthy foods and how it can lead to health conditions.
