While a sweet potato does provide some nutritional value, most dietitians and nutritionists would not recommend eating only a sweet potato for dinner. A balanced meal should include a source of protein, healthy fats, complex carbohydrates, and micronutrients from fruits and vegetables. Eating just a sweet potato is likely to leave you deficient in several key nutrients.
Nutritional Content of Sweet Potatoes
Sweet potatoes are packed with beneficial nutrients including:
- Vitamin A – One medium sweet potato provides over 100% of your daily vitamin A needs.
- Vitamin C – One sweet potato provides about 28% of your daily vitamin C needs.
- Potassium – With 542mg per medium potato, sweet potatoes are an excellent source of potassium.
- Fiber – One medium sweet potato has around 4 grams of fiber.
- Antioxidants – Sweet potatoes contain antioxidants like beta-carotene and anthocyanins.
While sweet potatoes provide lots of key micronutrients, they are lacking in some other areas:
One medium sweet potato only provides about 2 grams of protein. The recommended daily intake for most adults is around 46 grams for women and 56 grams for men. Eating only a sweet potato would leave you significantly short on this macronutrient.
Sweet potatoes contain minimal amounts of healthy fats. Healthy fats like omega-3s are important for hormone regulation, brain function, and heart health.
With just 41mg of calcium per potato, sweet potatoes are not a significant source of this mineral. Calcium is essential for bone health.
Benefits of Eating a Balanced Dinner
Instead of just eating a sweet potato alone, nutrition experts recommend eating it as part of a balanced dinner plate that provides:
Protein provides amino acids that are used for building and repairing muscle, skin, bones and other tissues in the body. It also helps keep you feeling full and satisfied after a meal. Good protein sources include fish, poultry, eggs, lean red meat, beans, lentils, nuts and seeds.
Sources of healthy fats like olive oil, avocados, nuts and salmon provide essential fatty acids and help with the absorption of fat-soluble vitamins. Healthy fats support brain function, regulate hormones, and control inflammation in the body.
Choosing nutrient-rich complex carbs like sweet potatoes, quinoa, brown rice and whole grains over simple carbs provides longer lasting energy and fiber. Fiber promotes digestive health and helps feed the beneficial bacteria in your gut microbiome.
Fruits & Vegetables
Filling half your plate with a variety of colorful fruits and veggies provides a plethora of vitamins, minerals and antioxidants that are vital to good health and disease prevention. They also add fiber, texture and flavor to meals.
Sample Balanced Dinner Plate
Here is an example of a balanced dinner plate that includes a sweet potato along with other nutritious foods:
|Protein||4oz grilled salmon|
|Healthy Fat||1⁄4 avocado|
|Complex Carb||1 medium baked sweet potato|
|Vegetables||1 cup roasted Brussels sprouts|
|Fruit||1 cup blueberries|
This dinner includes high-quality protein from salmon, healthy fats from avocado, complex carbohydrates from the sweet potato, and a variety of micronutrients from produce like Brussels sprouts and blueberries.
Health Consequences of Poor Dinner Choices
Eating a dinner focused solely around a starchy sweet potato and not including a proper balance of all the food groups can have negative health consequences including:
- Nutrient deficiencies – Lacking protein, healthy fats and micronutrients over time can lead to low energy, poor immunity, and increased risk of chronic illnesses.
- Blood sugar spikes – Eating lots of sweet potato without protein, fat or fiber causes rapid blood sugar spikes and crashes.
- Increased hunger – Not getting adequate protein and fats leads to quick returns of hunger.
- Weight gain – Poor portion control and increased hunger promotes overeating and weight gain over time.
- Gut health issues – Not getting enough fiber feeds bad bacteria leading to digestive problems.
Tips for Building a Balanced Dinner Plate
Follow these simple tips for creating a nutritionally balanced dinner plate:
Pick a Protein
Choose a protein source such as chicken, fish, eggs, pork, beef, tofu, beans, lentils, nuts or seeds.Aim for a palm-sized 4-6oz portion.
Add Healthy Fat
Include a thumb-sized serving of healthy fats like olive oil, avocado, nuts, seeds or omega-3 rich fish. This boosts flavor and satisfaction.
Include Complex Carbs
Fill 1⁄4 of your plate with fiber-rich complex carbs like sweet potatoes, quinoa, brown rice or whole grains to provide sustained energy.
Pile on Produce
Fill half your plate with a variety of colorful fruits and vegetables to load up on vitamins, minerals and antioxidants.
Be mindful of appropriate portion sizes for your calorie needs. Limit starchy carbs to 1⁄4 of plate.
Drink water before and during the meal to aid digestion and prevent overeating. Herbal tea is another great option.
