White potatoes can be included as part of a Paleo lifestyle by those who can tolerate the carbs, but they’re not for everyone. Some people experience a sugar rush due to the high starch content and those people should probably stay away from white potatoes.
A Healthy Alternative
Sweet potatoes, on the other hand, are pretty universally Paleo-friendly. They’re also high in carbs, but they have more fiber than white potatoes, which helps slow the digestion of those carbs and prevent a sugar rush. For that reason, sweet potato fries are a better option than French fries. They can satisfy that salty/sweet craving without throwing your blood sugar completely out of whack.
Homemade Is Always Best
As always, you’re better off making your own. Restaurants almost exclusively fry their potatoes in rancid canola or hydrogenated vegetable oils. These oils are full of polyunsaturated fats (PUFA), which are very unstable and tend to oxidize when exposed to heat and light. Consuming the oxidized fat tends to result in oxidized cholesterol in our blood, and that’s the cholesterol we need to watch out for.
Tips and Tricks
You can make your own sweet potato fries by tossing them in salt and olive oil (or your choice of fat) before throwing them in the oven. If you really want to fry them, Mark Sisson has some tips on how to do so in the healthiest way possible.
