Anthropogenic EMF has bio-effects associated with blood glucose metabolism in many people and animals.  Some of the effects may be interpreted as adverse and some as "beneficial" -- depending on the study design and questions as well as the desired exposure outcome, if any.   Permeability of the blood-brain barrier, cell proliferation, or angiogenesis are examples of effects which may be desired for pharmaceutical delivery or wound healing, but undesired where tumors have been diagnosed.  Therapeutic EMF uses controlled exposures, but the dense artificial EMF atmosphere in which we are forced to live is far from controlled.  This map links studies and articles about EMF effects on blood glucose and insulin levels and functions.  The viewer is free to draw his/her own conclusions.
