I have had clients ask me about eating potatoes versus sweet potatoes, and what the difference was health wise.
I always say that you can never go wrong with eating your veggies, but all veggies are not created equally.
Potatoes are enjoyable as roasted, mashed, fried, and baked; skin on, skin off…they are great and tasty in many forms. However, they have a GI (glycemic index) value of between 56-111 (depending on the potato), which is at the top of the chart. For more info on the Glycemic Index: http://en.wikipedia.org/wiki/Glycemic_index
Sweet potatoes, on the other hand are in the medium category on the GI, and have a host of other benefits such as antioxidants and high fiber content. For more info on sweet potatoes, check out this site: http://www.whfoods.com/genpage.php?tname=george&dbid=69
As with all carbohydrate rich foods, you should take care to eat only what your body needs, and keep your plate mostly loaded with high fiber, colorful veggies with low caloric values, such as spinach, green leaf lettuce, and celery.

That’s all for now; remember to eat well most of the time to enjoy the benefits of your workout program. If you work out hard but eat a ton of junk, you may still remain at the same weight and not look any differently.
