There is a lot of confusion when it comes to "White" carbohydrates. Many people automatically think that white = bad. I think this requires some clearing up...
White carbohydrates are generally given a bad reputation because they are processed. These are the BAD carbs if you will. White flour and white rice and the things made with these ingredients (white bread, cookies, cakes, etc) fall into this category. It's best to keep these things to a bare minimum. Maybe a treat here and there, but not a regular food in your diet.
Other white foods that fall under the GOOD carbs category include white kidney beans, white potatoes, popcorn and cauliflower. Potatoes and popcorn are starchy carbs that don't offer as much nutritional value as other things, like sweet potatoes, so I would limit your intake of these as well. Kidney beans and cauliflower are great options. You can eat these as much of these as you like.
Any other great white foods out there?
