Types of Sweet Potatoes
There are four main types of sweet potatoes: Beauregard, Garnet, Jewel, and Purple.
- Beauregard is the most common type grown in the United States. They have red skin and orange flesh and are perfect for roasting, baking, or mashing.
- Garnet has dark red skin and deep orange flesh. They're often used in soups and stews because they hold their shape well when cooked.
- Jewel has copper-colored skin and yellowish flesh. They're great for roasting or baking.
- Purple has purple skin and white flesh. They're perfect for making chips or fries because they hold their shape well when cooked.
The sweet potato is an important source of starch and vitamin A. It is one of the most nutritious foods on earth. They contain more than 100% of your daily requirement of Vitamin A, plus vitamins B6, B1, C, E, K, calcium, iron, magnesium, phosphorus, potassium, zinc, copper, manganese, selenium, and thiamine.

It is a highly productive sweet potato cultivar that yields up to twenty pounds of sweet potatoes per plant. Beauregard is resistant to many major diseases, including common scabs, blackleg, and ring rot. Additionally, Beauregard is tolerant of drought conditions and does not require irrigation.
The Beauregard sweet potato is grown primarily in the southern states of the US. It is the primary cultivar used for commercial sweet potato growing in the south. With its long history of cultivation dating back over 200 years, the Beauregard is considered one of the oldest cultivated sweet potato varieties in existence.
During World War II, the American government encouraged farmers to increase food production for the war effort. As part of this program, scientists at the Agricultural Research Service (ARS), located within the USDA, developed several new sweet potato cultivars. One of those cultivars was "Beauregard." ARS scientist John T. Gentry traveled to Louisiana during the 1940s and collected seeds from local farmers. These seeds were sent to the ARS laboratory and crossbred with existing cultivars. From this breeding process came the Beauregard cultivar.
Berkeley Sweet Potatoes
Berkeley sweet potatoes are typically light orange. They have thin skin and are moist and sweet when cooked. Berkeley is named after the University of California, Berkeley, where it was developed.
Berkeley was developed in the late 1970s by a team of scientists led by Dr. James N. Doyle. The project aimed to create a sweet potato that was more resistant to disease and pests and had a higher sugar content than other varieties.
After years of cross-breeding different varieties, the team finally succeeded in creating the Berkeley Sweet Potato. This variety was more resistant to disease and pests and had a higher sugar content than other varieties.

Sweet Potatoes vs. Yams: What's the Difference?
There's no doubt about it—the world loves sweet potatoes. But many people don't know that there's another type of tuber vegetable out there called a yam. And while you might think that they look similar, they're quite different.
The name "yam' refers to a family of root vegetables that includes sweet potatoes, cassava, taro, and others. These tubers grow underground and come in several varieties.

This doesn't mean that they don't taste good together, though. Combining them creates some delicious dishes. You can find sweet potato recipes like Yam Fries, Sweet Potato Pie, and Sweet Potato Pancakes online.
But even though they're close relatives, they're still completely different types of foods. Here's how they differ.
Yams are much larger than sweet potatoes. On average, they weigh anywhere from 3 pounds to 10 pounds each. A typical sweet potato weighs less than 2 pounds.
Sweet Potato Fry Technique
Are Sweet Potatoes Paleo?
Yes! Sweet potatoes are a fantastic source of vitamins and minerals - especially vitamin A. They are also great sources of high-quality protein and antioxidants.
Please note, however, that the type of Vitamin A found in sweet potato is beta carotene, and only about 5% of the Beta Carotene is converted into Retinol, the usable and active form of Vitamin A.
Vitamin A is important for vision, bone growth, reproduction, cell division, immune function, skin maintenance, and healthy teeth. However, most people don't consume enough beta-carotene-rich foods like sweet potatoes, broccoli, carrots, cabbage, spinach, kale, collard greens, turnip greens, and winter squash to meet their daily requirements.
How Do Potatoes Become Sweet?
Sweet potatoes are one of the most popular root vegetables around the world. They're a staple food throughout Africa, Asia, and Latin America. But how does a vegetable often cooked in water turn into something that tastes like candy?
The answer lies in what happens to the potato as it cooks. Unlike other fruits and vegetables, which contain starch, potatoes contain many complex carbohydrates known as starches. The starches begin to swell up like little balloons inside each cell when you cook a potato. As they expand, the potato becomes softer and sweeter.
How To Store Sweet Potatoes
Once you get them home, put them in a cool, dark spot away from heat and moisture. Ideally, store them in a room where there is air circulation. If you live in a warm climate, try putting them in a cold garage or basement. A closet works too.
The ideal temperature for storage is around 55 degrees Fahrenheit. This allows the starch inside the potato to remain soft without causing the skin to become tough. Temperatures above 60 degrees can cause the potatoes to turn brown.
Don't refrigerate them. Refrigeration causes the starch to go rancid and makes the potatoes taste like cardboard.
If you want to refrigerate them, take them out of the fridge for about 30 minutes before cooking. Otherwise, they won't cook evenly.
