The inspiring Annika Sjö has been in touch with the founders of paleolifestyle.se and received some information on…. potatoes…. I translated the answer into English for ya. Go to Annika’s blog for more info and health tips!
Why sweet potatoes, and not normal potatoes in the Paleo way of eating?
Sweet potatoes can be eaten raw – that doesn’t work so well with normal potatoes. As a matter of fact, sweet potatoes are not even potatoes, they are an herb.
Normal potatoes contains sugar. Sweet potatoes do not, despite their name. 🙂
Normal potatoes contain saponins och lectins. Saponins are poisonous in high doses and lectins are a sort of protein that binds to colon cells and effect the way nutrients are absorbed.
