Potato health benefits and why you should eat more spuds

From mashed potatoes, scalloped cheesy potatoes and the fast-food fried variety, potatoes are everywhere. They’re by far one of the most popular vegetables in America. But are potatoes good for your health?

There seems to be a lot of misconceptions on the health benefits of potatoes. UC Davis Health dietetic intern Adrienne Posner breaks down the nutrition facts on potatoes and why you may want to serve them at your next meal.

Are potatoes vegetables?

Yes. Potatoes are stem tubers and are considered a starchy vegetable. As the name implies, these vegetables contain more starch as compared to others. This isn’t bad. It means that the vegetable delivers more calories and typically less fiber.

Starch is a type of carbohydrate that our body breaks into glucose to use as energy. Therefore, starchy foods could be a good food source if you want to add calories or add a food choice to round out a meal.

Many cultures serve sides of rice, pasta, or potatoes with meals. These choices add calories and give a “full feeling” to hungry families. Other types of starchy vegetables include:

Potatoes for health and nutrition

In addition to starch, potatoes contain vitamins, minerals, and fiber. They’re rich in vitamin C, which is an antioxidant. Potatoes were a life-saving food source in early times because the vitamin C prevented scurvy. Another major nutrient in potatoes is potassium, an electrolyte which aids in the workings of our heart, muscles, and nervous system. Potato skin contains fiber, which is important for digestive health.

Different types of potatoes, especially those that come in other colors, contain more nutrients that have health benefits. In general, the darker the potato, the more antioxidants it contains. Sweet potatoes are a good source of vitamin A, an important nutrient for immunity and eye health. Purple potatoes are rich in antioxidants including anthocyanins which may prevent heart disease and cancer and boost brain health.1

Types of potatoes

Potatoes come in all colors, shapes, and sizes. There are many different varieties of potatoes. Some of the common types at most grocery stores include:

Fingerling potatoes: Small, stubby, finger-shaped potatoes

Russet potatoes: Large potatoes with dark brown skin and white flesh

Sweet potatoes: Large potatoes with bright orange flesh and sweet taste

White and red potatoes: Many sizes and shapes with either white- or red-colored skin

Purple potatoes: Oval-shaped potatoes with a purplish-black skin and purple flesh

What makes potatoes unhealthy?

Generally, potatoes move into the less than healthy category when they are loaded with toppings such as cheese, sour cream, and bacon. When you are mindful of both portion size and toppings, potatoes can provide comfort and satisfaction with any meal.

So why eat potatoes?

In addition to being budget-friendly, there are many health benefits to potatoes. They’re rich in energy, fiber, vitamins, and minerals. Try to include different varieties of potatoes in your diet to maximize the nutritional benefits.

The popular Paleolithic diet, or paleo diet, centers on the idea that eating like our ancestors aligns with our genetics and promotes good health. It’s also known as the caveman, Stone Age, or steak and bacon diet. A paleo dieter’s food choices are limited to what could be hunted, fished, or gathered in prehistoric times such as meats, fish, and vegetables.

The theory is that the rise in chronic diseases in modern society stems from the agricultural revolution. It suggests that adding grains, legumes, and dairy to meals may lead to a host of chronic diseases and conditions — from obesity to allergies.

UC Davis Health registered dietitians answer some of your questions about the paleo diet.

Long-term studies don’t offer much information on how the paleo diet affects health. However, the diet has the potential to be a healthy way of eating. The typical paleo diet focuses on naturally raised meat and fish, as well as vegetables and fruits. It promotes avoiding dairy products and grains.

This diet can put you at risk for deficiencies in calcium and vitamin D, which are critical to bone health. At the same time, you may consume saturated fat and protein far above recommended levels due to eating so much meat. This can cause an increased risk of kidney and heart disease and certain cancers.
