If you’ve ever placed sweet potatoes and white potatoes side by side at the grocery store, you probably assumed they were close relatives. After all, they share the word “potato” in their name.

Surprisingly, they aren’t closely related at all.

At Lake Isabella Pharmacy, we enjoy sharing simple health and nutrition facts inspired by the fresh fruits and vegetables growing in Efie’s Garden. Sweet potatoes are a perfect example of how nature can surprise us.

Different Families, Different Plants

Sweet potatoes belong to the morning glory family (Convolvulaceae), while white potatoes belong to the nightshade family (Solanaceae), alongside tomatoes, peppers, and eggplants.

Although both grow underground and are commonly called potatoes, they evolved separately and have very different nutritional profiles.

What’s the Difference?

Sweet potatoes are naturally rich in beta-carotene, the plant pigment that gives orange varieties their vibrant color. Your body converts beta-carotene into vitamin A, an essential nutrient that supports healthy vision, immune function, and skin health.

White potatoes, on the other hand, provide more potassium and vitamin C than many people realize and can absolutely be part of a healthy eating pattern.

Rather than asking which one is “healthier,” it’s better to think of them as offering different nutritional strengths.

Not All Sweet Potatoes Look the Same

While orange sweet potatoes are the most common, you’ll also find varieties with purple or even white flesh.

Purple sweet potatoes owe their rich color to anthocyanins, the same naturally occurring plant compounds found in blueberries and blackberries.

Each colorful variety brings its own unique combination of nutrients to the table.

Did You Know?

Many people use the terms yam and sweet potato interchangeably, but they’re usually not the same thing.

True yams are native to Africa and Asia and belong to an entirely different plant family. In most American grocery stores, the vegetables labeled “yams” are actually sweet potatoes.

A Colorful Addition to Your Plate

Whether they’re baked, roasted, mashed, or added to soups, sweet potatoes are a delicious way to enjoy more colorful vegetables as part of a balanced diet.

At Lake Isabella Pharmacy, we believe healthy living starts with everyday choices—including what’s growing in the garden. Through Efie’s Garden, we’re excited to share interesting facts about the foods that nourish our community, one harvest at a time.
