We posted about this a month ago.  Now, new reports of a study in rats suggests the same thing!  Says CNN:

A new study in rats suggests that high-fat, high-calorie foods affect the brain in much the same way as cocaine and heroin. When rats consume these foods in great enough quantities, it leads to compulsive eating habits that resemble drug addiction, the study found.

Some rats were fed a regular diet or just 1 hour a day of fatty foods.  If they were then presented with fatty food, but had to first get an electric shock to “earn” the fatty food, they avoided it.  But the rats who ate the fatty food all the time accepted the painful electric shocks so that they could get their “fix!”  These researchers found that cocaine caused rats to do similar things.  Both cocaine and fatty food caused brain changes – changes in dopamine receptors!

1 hour a day of fatty foods for the rats might be like us having a burger, fries, and a coke maybe once a week?  Not every day.  For me, it’s best to avoid alltogether!

I have gotten quite used to the taste of food without added sugar/salt/fat.  I don’t want to get used to it again… So I try hard not to “cheat.”  If I “cheat” today, it will set me up to “cheat” tomorrow…
