I wouldn't say "no nutes", but I would say it's about as useful as celery...
Why would you even bother eating iceburg? Pick a much greener lettuce and you'll be better off.
If you're looking for low calorie lettuce, you've gone WAAAAAAYYY to far in worrying about calories. You could eat a truckload of green leaf lettuce and not gain weight. You're better off with the good nutes in green lettuce a few more calories than eating iceburg lettuce.
Just my 2cents.
