Don’t Eat Sweet Potatoes Until You Know These 13 Important Facts!

Sweet Potatoes Are Not the Same as Yams (and That Matters)Despite what grocery stores label, most “yams” sold in supermarkets are actually sweet potatoes.True yams are starchier, drier, and much less sweet.

They Are Loaded with Vitamin A – Sometimes Too MuchSweet potatoes are one of the richest sources of beta-carotene (vitamin A precursor) in nature.
