Intriguing study findings begin to explain how and why it's so hard to be good.
There's nothing quite like the satisfaction of biting into a freshly-baked cookie, a chocolate truffle, your favorite kind of ice cream — whatever confection you find most heavenly. Perhaps you get the same kind of "high" from a slice of cheesy pizza with a perfect, chewy crust. Unfortunately, cravings for these foods, and our inability to have just a bite and then stop, can sabotage the best efforts to lose weight and control blood sugar. You may hear someone jokingly say, "I can't help it. I am totally addicted to Reese's Peanut Butter Cups." What if it's not a joke? Could food addiction be real?
"Hi, my name is Susie and I'm a sugar-holic."
The "high" from eating certain foods can lead to compulsive overeating comparable to alcohol binges. When does a strong desire to eat something cross the line from a simple craving to a food addiction? It could be when that desire is so overwhelming there no longer seems to be a choice (i.e., to eat or not eat). Other signs: using food to "feel better" and regularly eating when you're not hungry.
Simon Thornley, Ph.D., a researcher at the Auckland Regional Public Health Service in New Zealand, recently made the argument that high-glycemic foods (sugary treats, white bread, potatoes) tend to be more addictive than low-glycemic foods (protein foods, legumes, some whole grains, green vegetables). On the other hand, you don't often hear people having overpowering cravings for salmon or Cobb salads.
Writing in the November 2008 issue of Medical Hypotheses, Thornley made striking comparisons between food addiction and tobacco addiction. Both are often characterized by the following:
1. consuming increasing amounts over time,
2. difficulty cutting back,
3. loss of control, and
4. withdrawal symptoms.
Thornley cites research showing that both addictive drugs and foods can affect neurotransmitters, the brain chemicals that regulate mood. Chief among these neurotransmitters is dopamine, which can create the "high" feeling associated with drug use, sex, and even shopping.

As I mentioned in an earlier post, one of the benefits that made it cost-effective for me to go with the real healthcare (HSA) plan rather than the phony (HRA) plan is that my company is now covering "preventative" medicines at $0 copay. The formulary for these, as stated by CVS/Caremark (my pharmacy benefits provider), covers all test strips, lancets, and control solutions. I dutifully get my doctor to write up prescriptions for all of my testing needs, submit...
