Katie Couric's Notebook: Food Addiction
For decades, Lay's potato chip ads taunted us with the slogan "Bet you can't eat just one."
Turns out they were right.
Scientists at the Scripps Research Institute served one group of rats a steady diet of nutritious food. The other group got unlimited quantities of high-fat goodies like cheesecake and bacon.
No surprise, the rats fed junk food became obese and lethargic. But here's the shocker: when the researchers replaced the junk food with healthy food, the rats wouldn't eat at all. They opted to starve instead.
The authors say it's just like drug addiction, a concept former FDA Commissioner David Kessler explained to me in a recent interview. His book ,The End of Overeating, shows how the food industry -- and our brain chemistry -- work to keep us all hooked.
It's a tough battle between self control and out of control eating, so just say no and send a message to these companies that snack is whack.
That's a page from my notebook.
