Endocrine system is not a term we are familiar with, in most cases. It is a collection of glands that regulate our body's important functions. These functions include growth, metabolism and sexual development, pretty important functions. The glands produce chemicals called hormones, which are directly released into the bloodstream. From there they travel to the organs they are targeted to work with. Each hormone's shape is specific to the target cell it affects, binding to hormone receptors on the cells.
The three classes of hormones, defined by their chemical structures are:
- Amino acid hormones, ie serotonin, adrenaline, and dopamine
- Peptide hormones, ie growth hormones, insulin, prolactin
- Steroid hormones, ie cortisol, testosterone, DHEA
Some fish in the great lakes and birds that eat these fish have been found to have problems caused by endocrine disrupters in their environment, as have some alligators in the Florida Everglades. Dr. David Brownstein believes our environmental surroundings may be affecting us humans, too. He believes over 60% of our population is currently suffering from some kind of thyroid problem. And he has no doubt one of the reasons we are seeing such an epidemic of thyroid problems is due to our toxic overload of various chemicals, including endocrine disrupters. Tomorrow we will do into some detail of what he believes these are.
