Starchy vegetables are a vital part of a balanced diet, offering essential nutrients alongside carbohydrates. While often compared to their non-starchy counterparts, these foods provide fiber, protein, and vitamins that contribute to overall well-being. Understanding how to incorporate them effectively can optimize your health, especially if you’re managing conditions like diabetes or aiming for stable blood sugar levels.
Most adults should aim for roughly 2.5 cups of vegetables daily, with approximately 5 cups being starchy vegetables each week. Pairing these with protein or fats can further support blood sugar regulation. Here’s a breakdown of 10 starchy vegetables to include in your diet:
1. Potatoes: Energy-Rich and Nutrient-Packed
Potatoes are a complex carbohydrate source, providing sustained energy due to their fiber content. Unlike simple carbs, they digest slower, minimizing blood sugar spikes. They also deliver antioxidants, vitamin K, vitamin C, and potassium.
One medium potato (136g) contains:
- Calories: 118
- Protein: 2.5g
- Carbs: 49g
- Fiber: 2.7g
- Vitamin K: 31% DV
- Vitamin C: 20% DV
- Potassium: 11% DV
Those watching carbohydrate intake may want to moderate their potato portions.
2. Corn: Digestive Support and Antioxidant Benefits
Corn’s insoluble fiber aids digestion, keeping bowel movements regular. It also contains carotenoid antioxidants, which may benefit heart and eye health.
One medium ear of sweet yellow corn provides:
- Calories: 60
- Protein: 2g
- Carbs: 14g
- Fiber: 1.8g
3. Sweet Potatoes: Vitamin A Powerhouse
Sweet potatoes are a nutritional gem, especially rich in vitamin A, fiber, and potassium. Their fiber acts as a prebiotic, fostering beneficial gut bacteria. The resistant starch content can help with weight management and improve insulin sensitivity.
One medium sweet potato provides:
- Calories: 112
- Protein: 2g
- Carbs: 26.1g
- Fiber: 3.9g
- Vitamin A: 102% DV
- Potassium: 9% DV
Cooking and cooling sweet potatoes increases their resistant starch content.
4. Lentils: Plant-Based Protein and Fiber
Lentils are legumes packed with plant-based protein and fiber, promoting gut health and weight management. Their low glycemic index (GI) helps prevent blood sugar spikes. They also provide iron, potassium, magnesium, and other essential nutrients.
A half-cup serving of cooked lentils contains:
- Calories: 113
- Protein: 9g
- Carbs: 19.3g
- Fiber: 7.8g
- Iron: 18% DV
- Magnesium: 8% DV
- Potassium: 8% DV
5. Peas: Versatile and Nutrient-Dense
Peas are a good source of fiber, protein, iron, folate, and vitamins C, K, and B6. Their slow-digesting carbohydrates make them helpful for blood sugar control, particularly for those with type 2 diabetes.
One cup of cooked green peas contains:
- Calories: 134
- Protein: 8.6g
- Carbs: 25g
- Fiber: 8.8g
- Vitamin K: 35% DV
- Vitamin C: 25% DV
- Vitamin B6: 20% DV
6. Beans: Health Benefits Galore
Beans are another legume, offering plant-based protein, fiber, magnesium, folate, and iron. Studies link bean consumption to weight loss, reduced inflammation, and heart health. While evidence is limited, they may also lower the risk of colorectal cancer.
A half-cup serving of black beans provides:
- Calories: 120
- Protein: 7.6g
- Carbs: 22.5g
- Fiber: 7.7g
- Folate: 20% DV
- Iron: 15% DV
- Magnesium: 11% DV
7. Butternut Squash: Lower-Calorie Option
Butternut squash is high in fiber but lower in calories and carbs compared to other starchy vegetables. It’s rich in antioxidants, including carotenoids and vitamin C, which may protect against certain cancers.
One cup of cooked butternut squash contains:
- Calories: 82
- Protein: 1.8g
- Carbs: 21.5g
- Fiber: 6.6g
- Vitamin A: 127% DV
- Vitamin C: 34% DV
- Potassium: 12% DV
8. Pumpkin: Immune-Boosting Nutrients
Pumpkin is similar to butternut squash, being lower in calories and carbs while providing potassium and vitamins A and C for immune support.
One cup of mashed pumpkin provides:
- Calories: 49
- Protein: 1.8g
- Carbs: 12g
- Fiber: 2.7g
- Vitamin A: 78% DV
- Vitamin C: 13% DV
- Potassium: 12% DV
9. Parsnips: Vitamin-Rich Root Vegetable
Parsnips offer vitamin C, potassium, magnesium, and folate, along with fiber for blood sugar control.

- Vitamin C: 23% DV
- Folate: 23% DV
- Potassium: 12% DV
- Magnesium: 11% DV
10. Plantains: Starchy Fruit with Blood Sugar Benefits
Plantains, similar to bananas, are used as a starchy vegetable in cooking. They provide vitamin C and potassium, and studies suggest their resistant starch content may help improve blood sugar control in people with type 2 diabetes.
Incorporating starchy vegetables into your diet provides a range of health benefits, from sustained energy to improved gut health and blood sugar management. By understanding their nutritional profiles and how to prepare them, you can optimize these foods for your well-being.
