Are Potatoes Good for You?

By Liv

Potatoes are a staple food enjoyed worldwide, but they often get a bad rap.

Let’s explore the truth about potato nutrition. You might be surprised to learn that potatoes offer an array of nutrients and potential health benefits when prepared in a healthy way.

In this post, I’ll dive into the facts about potatoes, backed by the latest scientific research.

Key Takeaways

  • Potatoes are a nutritious source of carbohydrates, fibre, vitamins, and minerals when prepared in a healthy way.
  • Potatoes may offer health benefits, such as supporting heart health and aiding weight management.
  • Certain compounds in potatoes, like resistant starch and antioxidants, contribute to their nutritional value.
  • Preparation methods significantly impact the healthiness of potatoes, with boiling, baking, and roasting being better options than frying.

Here’s some helpful information about the nutritional profile of potatoes and how they can fit into a balanced diet.

Potato Nutrition Facts

Potatoes are a good source of several essential nutrients. Here’s a breakdown of what you can expect to find in a medium-sized (173g) baked potato with skin:

NutrientAmount
Calories161
Carbohydrates36.6g
Protein4.3g
Fat0.2g
Fibre3.8g
Vitamin C17.7mg
Potassium926mg

Potatoes also contain smaller amounts of other vitamins and minerals, such as vitamin B6, folate, magnesium, and iron. They are also a source of various plant compounds, including antioxidants like flavonoids and phenolic acids, which may contribute to their potential health benefits.

Carbohydrates and Fibre

Potatoes are primarily composed of carbohydrates, with a medium-sized potato containing about 36.6g of carbs. These carbs are mostly in the form of starch, which can be further classified into rapidly digestible starch, slowly digestible starch, and resistant starch.

Resistant starch acts similarly to dietary fibre and has been linked to several potential health benefits, such as improved blood sugar control and enhanced digestive health.

Speaking of fibre, a medium potato with skin provides about 3.8g, which is roughly 15% of the daily recommended intake. The majority of the fibre in potatoes is found in the skin, so it’s best to consume potatoes with the skin on to maximise their fibre content.

Essential Nutrients

One of the most notable vitamins in potatoes is vitamin C, with a medium baked potato providing about 28% of the daily recommended intake. Vitamin C is a powerful antioxidant that supports immune function, collagen synthesis, and iron absorption.

Potatoes are also an excellent source of potassium, with a medium potato offering 26% of the daily recommended intake. Potassium is crucial for maintaining proper nerve and muscle function, as well as regulating blood pressure.

By including potatoes as part of a balanced diet, you can benefit from the various nutrients they provide.

Potential Health Benefits

The nutrients and plant compounds found in potatoes may offer several health benefits when consumed as part of a balanced diet.

  • May support heart health: The potassium in potatoes may help regulate blood pressure, a major risk factor for heart disease. The fibre in potatoes can also help lower cholesterol levels.
  • Could aid weight management: Potatoes are relatively low in calories and high in fibre, which can help promote feelings of fullness and reduce overall calorie intake. However, the preparation method significantly impacts the calorie content, with boiled or baked potatoes being better choices than fried or processed options.

It’s important to remember that the potential health benefits of potatoes depend on factors like preparation method, portion size, and overall dietary context.

Safety Concerns and Side Effects

While potatoes are generally safe and nutritious for most people, there are a few potential safety concerns and side effects to be aware of:

  • Potato allergies: Although rare, some people may have an allergic reaction to patatin, the main protein found in potatoes.
  • Glycoalkaloid toxicity: Potatoes naturally contain compounds called glycoalkaloids, which can be toxic in high amounts. To minimise the risk, avoid consuming green or sprouted potatoes and remove any sprouts or green spots before cooking.
  • Acrylamide formation: When potatoes are cooked at high temperatures (e.g., frying, roasting), a potentially harmful compound called acrylamide can form. To reduce acrylamide formation, avoid storing potatoes in the refrigerator, soak cut potatoes before cooking, and cook potatoes at lower temperatures.

Healthy Preparation Methods

The way you prepare potatoes can significantly impact their nutritional value and overall healthiness. Here are some of the best ways to prepare potatoes to maximise their nutrients and minimise potential harmful compounds:

  • Boiling: Boil potatoes with their skins on and avoid overcooking to retain the most nutrients.
  • Baking and roasting: Cook potatoes at lower temperatures (around 180°C) and avoid browning them too much. Cut potatoes into larger pieces to reduce the surface area exposed to high heat.
  • Microwaving: Pierce the potato skins with a fork to allow steam to escape, and cook on high power until tender.

Some potato preparation methods, like frying and processed potato products, are less healthy and should be limited or avoided.

FAQ

  • Are potatoes high in carbs? Yes, potatoes are relatively high in carbohydrates compared to other vegetables. A medium-sized potato contains about 36.6g of carbs.
  • Can potatoes be part of a weight loss diet? Potatoes can be part of a weight loss diet when prepared in a healthy way and consumed in moderation. Boiled or baked potatoes are lower in calories than fried or processed options.
  • Is it healthy to eat potato skins? Yes, potato skins are a good source of fibre and other nutrients. It’s best to consume potatoes with the skin on to maximise their nutritional value.
  • What’s the healthiest way to cook potatoes? Boiling, baking, and microwaving are some of the healthiest ways to prepare potatoes, as they minimise the formation of harmful compounds and retain the most nutrients.
  • Are sweet potatoes healthier than regular potatoes? Sweet potatoes and regular potatoes have different nutritional profiles. Sweet potatoes are higher in vitamin A, while regular potatoes are higher in potassium. Both can be part of a healthy diet when prepared in a nutritious way.

The Bottom Line on Potato Nutrition

In conclusion, potatoes can be a nutritious addition to a balanced diet when prepared in a healthy way. They offer a variety of essential nutrients, including carbohydrates, fibre, vitamins, and minerals, and may provide potential health benefits like supporting heart health and aiding weight management.

However, it’s important to be mindful of preparation methods and portion sizes, as these factors can significantly impact the healthiness of potatoes. By choosing nutritious cooking methods like boiling, baking, and microwaving, and limiting less healthy options like frying and processed potato products, you can enjoy the many benefits of this versatile vegetable as part of a balanced diet.
