Are Sweet Potatoes Healthy?

Macronutrients

• Calories. A medium-sized sweet potato (approximately 130 grams) contains around 112 calories, making it a low-calorie food option.
• Carbohydrates. Sweet potatoes are a rich source of complex carbohydrates, with a medium-sized sweet potato providing about 23 grams of carbs.
• Protein. While not a high-protein food, sweet potatoes offer about 2 grams of protein per medium-sized potato.
• Fat. Sweet potatoes are naturally low in fat, containing less than 0.2 grams of fat per medium potato.

Vitamins

• Vitamin A. Sweet potatoes are exceptionally high in vitamin A, primarily in the form of beta-carotene.
• Vitamin C. They also provide a good amount of vitamin C, which is essential for immune function and skin health.
• Vitamin B6. Sweet potatoes contain vitamin B6, which plays a role in brain development and function.
• Vitamin E. This vitamin is an antioxidant that helps protect cells from damage.

Minerals

• Potassium. Sweet potatoes are an excellent source of potassium, which helps regulate blood pressure and fluid balance.
• Manganese. This mineral is involved in metabolism, bone formation, and antioxidant functions.
• Magnesium. Important for muscle and nerve function, as well as bone health.
• Calcium and iron. Sweet potatoes also provide smaller amounts of calcium and iron, contributing to overall mineral intake.

Dietary fibre

• A medium-sized sweet potato contains about 5 grams of dietary fibre, which supports digestive health and helps maintain steady blood sugar levels.

1. Rich in antioxidants. The high levels of beta-carotene in sweet potatoes act as antioxidants. This may reduce the risk of chronic diseases, such as heart disease and cancer.
2. Supports eye health. The vitamin A content in sweet potatoes is crucial for maintaining good vision and eye health. Beta-carotene is converted to vitamin A in the body, which is essential for the production of light-detecting receptors in the eyes.
3. Boosts immune system. Vitamin A and vitamin C in sweet potatoes strengthen the immune system. Vitamin A plays a role in maintaining the integrity of mucous membranes, while vitamin C stimulates the production of white blood cells.
4. Promotes digestive health. The dietary fibre in sweet potatoes supports healthy digestion by promoting regular bowel movements and preventing constipation. Fibre also acts as a prebiotic, feeding beneficial gut bacteria.
5. Regulates blood sugar levels. Despite being a carbohydrate-rich food, sweet potatoes have a low glycemic index, meaning they release sugar slowly into the bloodstream. This helps prevent spikes in blood sugar levels and is beneficial for people with diabetes.
6. Supports heart health. Potassium in sweet potatoes helps regulate blood pressure by counteracting the effects of sodium. The fibre content also helps lower cholesterol levels.
7. Anti-inflammatory properties. Sweet potatoes contain choline, a nutrient that may help reduce chronic inflammation. Chronic inflammation is associated with various diseases, including cardiovascular disease and arthritis.
8. Enhances brain function. The antioxidants and vitamins in sweet potatoes support cognitive function and brain health. Vitamin B6 is involved in the production of neurotransmitters, which influence mood and cognitive function.

Sweet potatoes and weight gain

Some people believe that sweet potatoes contribute to weight gain due to their carbohydrate content. However, sweet potatoes are low in calories, naturally low in fat, and high in fibre, which promotes a feeling of fullness and can aid in weight management when consumed in moderation.

Sugar content

While sweet potatoes are sweet, they have a lower glycemic index than regular potatoes, meaning they have a lesser impact on blood sugar levels. Their natural sugars are released slowly into the bloodstream. It’s certainly not the type of refined sugar you would find in confectionery! 

Nutritional superiority

There is a common misconception that sweet potatoes are nutritionally superior to regular potatoes. Both have unique nutritional profiles and health benefits, and one is not necessarily better than the other. Including both in your diet can provide a range of nutrients.

1. Baking. Baking sweet potatoes is a simple and healthy way to prepare them. Simply wash, poke holes with a fork, and bake at gas mark 6 / 400°F (200°C) for about 45 minutes or until tender. Enjoy as a side dish or stuffed with healthy toppings like black beans, salsa, and avocado.
2. Boiling and mashing. Boil sweet potatoes until tender, then mash them with a little olive oil, garlic, and herbs for a nutritious side dish.
3. Roasting. Cut sweet potatoes into wedges, toss with olive oil, and season with spices like paprika, cumin, and rosemary. Roast at gas mark 6 /  425°F (220°C) for 25-30 minutes for a delicious and crispy treat.
4. Grilling. Slice sweet potatoes into rounds, brush with olive oil, and grill until tender and slightly charred. Grilled sweet potatoes make a great addition to salads or as a side to grilled meats.
5. Soups and stews. Add diced sweet potatoes to soups and stews for added flavour, nutrition, and a touch of sweetness.
6. Smoothies. Blend cooked sweet potato with your favourite smoothie ingredients for a creamy and nutrient-packed drink.
7. Sweet potato chips. Cut sweet potatoes into thin strips, toss with a little olive oil and salt, and bake until crispy for a healthier alternative to traditional chips.

GLP-1 receptor agonists delay stomach emptying and enhance fullness. Eating large portions of heavy or refined carbs can therefore lead to:

• Nausea or bloating
• Blood sugar spikes followed by fatigue
• Reduced intake of protein and other nutrients

Choosing the right carbohydrates helps you:

• Maintain steady energy levels
• Support digestive comfort
• Balance meals without overeating
• Keep blood sugar levels more stable
