7 Ways Sweet Potatoes Help You Manage Stress

by Michelle Beadle Holder, PhD

While stress is a natural part of life, it can feel like an almost constant companion. Whether it's the pressure of work deadlines, personal responsibilities, social, political, or economic turmoil, or the general pace of modern life, stress can take a significant toll on our physical and mental well-being. While seeking relief through vacations or relaxation techniques is important, there may be one simple, yet powerful stress-busting tool already in your kitchen: the sweet potato.

Beyond being a delicious and versatile food, sweet potatoes are packed with nutrients that can help our bodies cope with and recover from stress. Below are seven reasons to consider adding sweet potatoes to your stress relief toolkit:

1. Complex Carbohydrates for Sustained Energy

When stressed, your body can go into "fight-or-flight" mode which often leads to quick energy crashes. Turning to refined sugars or caffeine can provide a temporary energy boost. However, these quick fixes are often followed by an energy dip that can leave you feeling worse.

Sweet potatoes, on the other hand, are a rich source of complex carbohydrates. Compared to white potatoes or more refined convenience foods, the slow-digesting carbs of sweet potatoes provide a steady, sustainable release of glucose into the bloodstream, helping to maintain energy levels without the spike-and-crash effect. Sweet potatoes can make a noticeable difference in how you feel throughout a busy, stressful day.

(Note: Sweet potatoes have a medium to high glycemic index (GI), ranging from 44 to 96. Since the GI measures how quickly blood sugar levels rise after eating, consuming large amounts in one meal may not be ideal for people with type 2 diabetes. Moderation is key.)

2. Magnesium to Calm the Nervous System

Magnesium is a key mineral in the body. It plays a significant role in managing stress and promoting relaxation. Deficiency in magnesium stores can contribute to feelings of anxiety, irritability, and physical tension. Sweet potatoes are a good source of magnesium, which can help to regulate the body’s stress response.

By including more magnesium-rich foods like sweet potatoes in your diet, you can support the nervous system, reduce muscle cramps, and encourage a sense of calm during stressful moments.

3. Antioxidants to Combat Oxidative Stress

Stress doesn’t just take an emotional toll. It can increase oxidative stress in the body. Oxidative stress is a condition where free radicals overwhelm our cells. Over time, oxidative stress contributes to aging and chronic health conditions.

Sweet potatoes are rich in antioxidants, especially beta-carotene, which is converted to vitamin A in the body. These antioxidants help neutralize free radicals, protecting your cells from the harmful effects of chronic stress and helping to maintain a healthy immune system.

4. Fiber for Gut Health and Emotional Well-being

Consuming a diet high in highly processed convenient foods, which often lack essential nutrients like fiber, can have a significant impact on mood and emotional well-being. Fiber plays a crucial role in supporting gut health. A lack of fiber can disrupt the delicate balance of the gut microbiome. When the gut is out of balance, it can negatively affect the production of neurotransmitters like serotonin, which regulate mood and emotions. Without enough fiber to nourish beneficial gut bacteria, harmful bacteria can thrive. This imbalance can contribute to mood swings, irritability, and even anxiety or depression. In essence, the absence of fiber-rich, whole foods can not only affect digestion but also create a ripple effect that compromises emotional stability and overall mental health.

The connection between the gut and the brain (often called the “gut-brain axis”) is well-established in scientific literature. Poor gut health can have a direct impact on mood regulation, including increased feelings of anxiety and depression. Sweet potatoes are an excellent source of dietary fiber, which supports a healthy digestive system. By improving gut health, sweet potatoes may help optimize mood and reduce the emotional strain that often accompanies periods of high stress.

5. Vitamin C to Regulate Cortisol Levels

Cortisol, the body's primary stress hormone, is essential for managing the “fight or flight” response. However, chronic stress can lead to elevated levels of cortisol, which can weaken the immune system and affect overall well-being. Research suggests that Vitamin C could aid in the body’s ability to regulate cortisol levels. Fortunately, sweet potatoes are also a good source of vitamin C, which can help replenish this important nutrient during stressful times.

6. Potassium for Better Sleep and Relaxation

Stress can wreak havoc on our sleep patterns, and poor sleep can, in turn, exacerbate stress. Potassium, a mineral found in sweet potatoes, helps regulate fluid balance and supports proper muscle function, which is important for achieving restful sleep. Potassium also helps reduce the physical tension that can build up in the body during stress. By incorporating potassium-rich foods like sweet potatoes into your diet, you can support relaxation and promote more restful nights, helping to break the cycle of stress-induced sleep deprivation.

7. Versatility and Comfort in Every Bite

On top of all the nutritional benefits, sweet potatoes offer a sense of comfort that can be crucial when we're feeling stressed. Their natural sweetness and hearty texture can be a soothing way to nourish your body. Whether baked, mashed, or roasted, they are versatile ingredients that can be incorporated into a wide range of meals, making them easy to enjoy while also reaping their stress-relief benefits.

Sweet Potatoes are More Than Just a Side Dish

While no single food can completely eliminate stress, sweet potatoes are a nutritious, accessible, and delicious way to support your body during stressful times. From stabilizing blood sugar levels to promoting relaxation, sweet potatoes offer a range of benefits that can help reduce the physical and emotional toll of stress. By adding more sweet potatoes to your diet, you're not just nourishing your body, you're investing in your mental well-being too.

Incorporate this humble vegetable into your next meal, and take a small but powerful step toward better health during stress.
