They were in my local store today, so I bought a few and plan to go get more before they're gone!
Purple sweet potatoes earn their crown for a few standout reasons, and it is not hype.
They are rich in anthocyanins, the same antioxidant compounds found in blueberries and blackberries. These pigments give them their deep purple color and are studied for their role in supporting cellular resilience and reducing oxidative stress from everyday life.
Unlike many colorful foods, purple sweet potatoes are also:
Naturally high in fiber, which supports digestion and steadier blood sugar response
A source of complex carbohydrates that provide sustained energy rather than quick spikes.
Rich in polyphenols that remain relatively stable even after cooking.
They are also lower on the glycemic index than many orange sweet potato varieties, especially when cooled after cooking, which makes them a favorite in nervous system and metabolic supportive nutrition.
In short, purple sweet potatoes are not just colorful. They deliver nutrient density, antioxidant power, and grounding nourishment in one humble food.
