Understanding how sweet potatoes became a key component of healthy living involves delving into their nutritional benefits, historical significance, and cultural relevance across different societies.
Sweet potatoes belong to the Convolvulaceae family, which includes morning glory plants. They are often confused with yams, which are entirely different tubers with a rougher texture and a starchy flavor profile. Sweet potatoes come in various varieties, each offering a unique taste and texture.
