Is a sweet potato enough for dinner?

Quick Answer

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.

Healthy Fats

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.

Healthy Fats

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.

Complex Carbohydrates

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:

Food Group 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.

Watch Portions

Be mindful of appropriate portion sizes for your calorie needs. Limit starchy carbs to 1⁄4 of plate.

Stay Hydrated

Drink water before and during the meal to aid digestion and prevent overeating. Herbal tea is another great option.
