Researchers at the University of Gothenburg, Sweden, have now presented results that may change our basic view of how type 2 diabetes occurs. Their study indicates that free fatty acids (FFAs) in the blood trigger insulin release even at a normal blood-sugar level, without an overt uncompensated insulin resistance in fat cells. What is more, the researchers demonstrate the connection with obesity: the amount of FFAs largely depends on how many extra kilos of adipose tissue a person carries, but also on how the body adapt to the increased adiposity.
