Dont worry gibbob2 regular baked potatoes are still a good source of starch, fiber and vitamins and minerals. Although sweet potatoes are usually higher in certain vitamins and minerals with a lower GI value they are more pricey. Most regular potatoes do have a higher GI value but it varies on the type and preperation of the potatoe, yet they are cheaper. One thing to consider regarding the GI value of a reg. potatoe is since there is a decent amount of fiber it slows the absorption of starches being digested, add some greens or grains and the fiber content is increased even more . Anywho, they surely are more economic alternative to sweet potatoes, but don't forget to incorporate or substitute a regular potatoe for a sweet potatoe every now and again.
