Hormones get a lot of bad press, especially when people are talking about food. So what are these things, why do we care, and are they good or bad?
Hormones are basically messengers. They are little proteins that are made by one part of the body, they travel through the blood to another part of the body, and then they tell that part of the body what to do.
For example… Insulin is a hormone. It is made by the pancreas, travels through the blood to all the other tissues and cells in your body, and tells your cells when to take glucose out of your blood and into the cells. The cells then use glucose for energy.
