Potatoes – High in Starch
Potatoes are a perplexing food when you’re preparing a paleo diet for yourself. On one hand, they are clearly a paleo-lithic food in the sense that they have been around for thousands upon thousands of years and require little to no processing to make them edible and provide energy. On the other hand, they are extremely high in starch and have a high GI.
For those last reasons, we don’t recommend eating potatoes, especially white potatoes on a regular basis. If ever. The problem with potatoes lies in their starch and content. If you have any insulin resistance whatsoever (pretty likely) than this can wreak havoc on your metabolism and makes them hard to digest. In addition, due to their high GI (glycemic index), they will make your blood sugar spike unexpectedly.
If you are going to eat potatoes, eat them without the skin and try for sweet potatoes or yams. These contain a little less carbohydrates and starch which make them slightly more desirable.
