The Health Benefits of Sweet Potatoes

Sweet potatoes, of all types and colors, are filled with beneficial macronutrients and micronutrients.

Just one cup of cooked sweet potato yields a vast array of beneficial vitamins and minerals, complex carbohydrates, and satiating fiber. This provides 214 percent daily value of vitamin A, 44 percent daily value of vitamin C, and substantial amounts of B vitamins, iron, potassium, magnesium, manganese, and copper.

Vibrantly colored sweet potatoes contain a variety of different antioxidants including beta-carotene, chlorogenic acid, anthocyanins (specifically in purple sweet potatoes), and coumarins. These plant compounds are thought to beneficially affect our health by reducing and removing free radical accumulation and damage to cells.

Sweet potato is a rich source of soluble and insoluble fiber. Soluble fiber helps to increase feelings of fullness while slowing down blood sugar spikes and fluctuations. Insoluble fiber is associated with improved gut health and reduced risk of certain diseases, like type-2 diabetes.

How to Make Perfect Roasted Sweet Potatoes

First thing first, stock up on organic sweet potatoes at the farmers market or grocery store. These inexpensive tubers are often labeled as either yams or sweet potatoes, but are usually varieties of sweet potato.

Yams, which hail from Africa, are often hard to find and are much starchier and drier than their sweet potato cousins.

Sweet potatoes come in several sizes, shapes, and colors with names like Hannah, jewel, garnet, Korean purple, creamsicle, willowleaf, and more. For roasting purposes, I prefer to use purple sweet potatoes (which are gorgeous), garnet, and jewel varieties.

Sweet potatoes need high heat to roast perfectly, and with that a cooking medium that tolerates high heat. When roasting sweet potatoes, I prefer to use ghee or avocado oil, two mediums that have very high smoke points.

Ghee, or clarified butter, provides a nutty and buttery taste to roasted sweet potatoes second to none. Ghee also contains vitamins A, E, and K, along with butyrate, a type of short-chain fatty acid thought to promote the health of gut bacteria. Ghee has a smoke point of 480-500 degrees Fahrenheit, meaning it is suitable for high-heat cooking and roasting.

Avocado oil, which is made from pressed avocado, has a smoke point of 520 degrees Fahrenheit. Along with providing essential B vitamins and healthy fats, avocado is versatile cooking oil that makes roasted sweet potatoes shine.
