My first few weeks as Putnam County’s new Rural Community Health Agent have been packed with activity. Some highlights include getting to know my new coworkers, learning about Putnam County, and providing health and nutrition lessons for youth in 4-H Cloverbuds Camp and Stars & Stripes Camp. I also got the chance to attend Potato Field Day at the Hastings Agricultural Extension Center. This program provided an opportunity for local growers and UF/IFAS Extension Agents and Extension Specialists to come together to discuss promising research on growing new and improved potato varieties. Both table stock and chip potato varieties were showcased. Potatoes provide valuable nutrition to people around the world, which is why it is important to continue improving potato varieties to increase both crop quality and nutrient density.
Nutrition at the Root
Potatoes are classified as starchy root vegetables as they are sources of quality complex carbohydrates. The two main starches in potatoes are amylopectin and amylose. Amylopectin is easily broken down by the human body and converted to glucose for energy. Amylose is not as easily digested as amylopectin and is sometimes referred to as resistant starch. New potatoes that are harvested early typically have a higher concentration of amylose when compared to mature potatoes. Knowing the differences in starch content of potatoes can be helpful for people who are managing their blood glucose levels. Pairing starchy vegetables like potatoes with healthy fats like olive oil and lean sources of protein can create more balanced meals and support steady blood glucose levels.
Little Packages, Big Benefits
Not only do potatoes supply the human body with energy, but they are also great sources of:
- potassium
- Vitamin B6
- Vitamin C
- fiber
One medium potato contains about 600 mg of potassium, which is an essential mineral. Potassium plays important roles in regulating heart rhythm and blood pressure, skeletal muscle movements, and nerve functioning. Vitamin B6 helps support brain health, metabolism, and the immune system. Vitamin C is a powerful antioxidant that helps protect cells from damage and is important for collagen production, immune system functions, and iron absorption. Lastly, one medium-sized potato with the peel typically has around 2-3 grams of fiber. Fiber is often overlooked as most Americans do not consume enough fiber every day. Fiber helps with managing blood glucose levels, supports a healthy gut microbiome, aids in lowering cholesterol levels, and contributes to healthy weight management. Enjoying potatoes for breakfast, lunch, or dinner can easily fit into a well-balanced eating pattern for children and adults.
From Field to Dinner Plate
As researchers seek to improve potato varieties, the focus is not only on increasing crop yields, but also on enhancing the nutritional value of those crops. Potatoes are one of the most popular foods in the world. With many cultures relying on potatoes as a staple food, it is critical that these root vegetables provide optimum amounts of nutrients. Research focused on potato breeding has helped develop varieties that yield higher amounts of iron and zinc, which helps to address nutrition and food security needs. Advances in potato breeding demonstrate how agriculture and nutrition can work hand in hand to support healthier populations.
Closing Thoughts
Attending Potato Field Day reminded me that good agricultural practices support good nutrition. The work being done by researchers today is helping improve potato varieties to support both successful crops and better health, ensuring potatoes will be a staple food in our food system for years to come.
