How many calories are in 120 g of new potatoes?

4 min read

According to nutrition data, a 120g serving of plain, boiled new potatoes contains approximately 90 calories. This makes them a nutritious and relatively low-calorie addition to meals, especially when compared to their mature counterparts or higher-fat cooking methods. Factors like cooking style and additions can alter the final count.

Quick Summary

A 120g portion of plain, boiled new potatoes contains around 90 calories. The final calorie total can be influenced by cooking methods, such as boiling versus frying, and any added ingredients like butter or oil.

Key Points

  • Low Calorie Count: 120g of plain, boiled new potatoes contains approximately 90 calories.

  • Cooking Method Matters: Frying and adding fats significantly increase the calorie count, while boiling and steaming keep it low.

  • New vs. Mature Potatoes: New potatoes are higher in moisture and lower in starch than mature potatoes, resulting in a lower calorie density.

  • Resistant Starch Benefit: Cooking and then cooling potatoes increases resistant starch, which reduces the number of absorbable calories and promotes gut health.

  • Nutrient Dense: New potatoes are a good source of potassium, vitamin C, and fiber, particularly when cooked with the skin on.

  • Focus on Simple Preparation: To keep the calorie count low, opt for boiling, steaming, or air frying with minimal added oil.

Calorie Breakdown for 120g of New Potatoes

For a 120-gram serving of boiled new potatoes, the calorie count is approximately 90 kcal. This measurement is based on potatoes cooked with their skins on in salted water, and it represents a modest energy contribution to a balanced meal. The primary source of these calories comes from carbohydrates, with a negligible amount of fat.

To put this into perspective, the calorie content can change based on the preparation and the potato's maturity. New potatoes are harvested early, giving them a waxy, high-moisture, and lower-starch profile than mature potatoes. A raw, mature potato of the same weight might have a slightly higher calorie count due to more concentrated starch. Ultimately, a simple boiling method keeps the calorie count low, making it a favorable option for those monitoring their intake.

New Potatoes vs. Mature Potatoes: A Nutritional Comparison

The primary distinction between new and mature potatoes lies in their starch content and moisture levels, which directly impacts their nutritional profile. New potatoes are higher in moisture and lower in starch, resulting in a slightly lower calorie density per gram compared to their fully grown counterparts.

  • Moisture Content: New potatoes have a higher water content, contributing to their creamy, waxy texture. Mature potatoes have less water and are drier.
  • Starch Levels: As potatoes mature, their simple sugars convert to starch. This is why mature potatoes are starchier and more floury, while new potatoes remain sweeter and less starchy.
  • Nutrient Concentration: While new potatoes are rich in vitamin C, potassium, and fibre, some nutrients become more concentrated in mature potatoes as they grow. However, the difference is often not substantial enough to make one vastly superior to the other for general nutritional purposes.

How Cooking Methods Impact Calorie Count

While a plain, boiled new potato is low in calories, the preparation method can drastically alter the final nutritional value. Adding fats like oil or butter is the most significant factor for increasing calories.

  • Boiling/Steaming: This is the healthiest preparation method for new potatoes, as it adds no extra fat. It also helps preserve some water-soluble nutrients like vitamin C, especially when cooked with the skin on.
  • Frying/Roasting: These methods involve adding fats, which are calorie-dense. Frying, in particular, can cause potatoes to absorb a considerable amount of oil, turning a healthy food into a high-calorie dish. For example, deep-fried chips can have over 600 calories per 100g, dramatically increasing the calorie count of a 120g portion.
  • Cooling and Reheating: A fascinating nutritional hack involves cooking and cooling potatoes. This process converts some of the digestible starch into 'resistant starch', which acts like dietary fibre. Resistant starch is not fully absorbed by the body, meaning the cooled potato has slightly fewer absorbable calories and can also help with gut health and blood sugar control.

Comparison Table: 120g Boiled vs. Fried New Potatoes

Feature 120g Boiled New Potatoes 120g Deep-Fried Potatoes (Approx.)
Calories ~90 kcal 250-300+ kcal (Estimate)
Fat ~0.4 g ~12-17 g (Estimate)
Carbohydrates ~17.1 g (per 100g) High, but varies with fat absorption
Texture Firm, waxy Crispy exterior, soft interior
Recommended For Healthy side dish, salads Occasional treat

Making Healthy Choices with New Potatoes

When aiming for a nutritious diet, the way new potatoes are cooked is as important as their inherent nutritional value. The basic, boiled or steamed potato with its skin intact is a powerhouse of nutrients like potassium and vitamin C. This simple preparation maximizes health benefits while minimizing the calorie load. Conversely, introducing high-fat cooking methods or toppings can quickly negate these advantages. Using a small amount of healthy fat like olive oil for roasting, or a sprinkle of herbs and spices, is a great way to enhance flavour without a major calorie increase.

For those interested in the concept of resistant starch, preparing a batch of new potatoes, boiling them, and then refrigerating them to be used in a salad later is a clever way to reduce their overall glycemic impact and absorbable calories. This makes them an even more versatile and health-conscious food choice.

The Nutritional Upside of New Potatoes

Beyond just their calorie count, new potatoes offer several nutritional benefits that make them a valuable part of a healthy diet.

  • They are naturally fat-free, cholesterol-free, and sodium-free.
  • They are a great source of potassium, which is essential for maintaining normal blood pressure.
  • The presence of fibre (especially in the skin) aids in digestion.
  • New potatoes contain antioxidants and are a good source of vitamin C.

Overall, new potatoes can be an excellent choice for a wide range of meals, from a simple side dish to a potato salad, provided they are prepared in a health-conscious manner. Keeping toppings and cooking fats minimal is the key to enjoying their nutritional benefits while managing calorie intake.

Conclusion

In summary, 120g of plain, boiled new potatoes contains a modest 90 calories, making them a healthy and low-fat option for many diets. This calorie count is influenced by the potato's young, high-moisture, and lower-starch nature compared to mature varieties. The cooking method is the most significant factor affecting the final calorie total, with frying and adding fats drastically increasing the count. For the lowest-calorie and most nutrient-dense option, boiling or steaming with the skin on is recommended. The presence of resistant starch in cooked and cooled potatoes offers an additional benefit for those looking to manage blood sugar and calorie absorption, confirming new potatoes as a versatile and beneficial food. To enjoy new potatoes while being mindful of calorie intake, focus on simple preparations and minimal additions.

Frequently Asked Questions

A 100g portion of new potatoes contains around 14.9g of carbohydrates. This means that a 120g serving would contain approximately 17.88g of carbohydrates, though this can vary slightly with cooking.

Yes, new potatoes are generally lower in calories per gram than mature potatoes. This is because they have a higher moisture content and a lower concentration of starch.

Boiling itself does not reduce the total calories of the potato, but it can alter the calorie density. Because some water is absorbed during boiling, a 100g serving of boiled potato may have fewer calories than 100g of baked potato, which loses water and concentrates calories.

Yes, to an extent. When cooked and then cooled, some of the starch in potatoes converts into resistant starch. This type of starch is not fully digested by the body, meaning fewer calories are absorbed.

The healthiest way to cook new potatoes is by boiling or steaming them with the skin on. These methods add no extra fat and help preserve valuable nutrients like vitamin C.

Fried new potatoes are significantly higher in calories than boiled ones due to the absorption of cooking oil. While a 120g boiled serving is about 90 kcal, a deep-fried serving of the same weight could be over 250 kcal.

Yes, new potatoes are a good source of vitamins and minerals. They are particularly rich in vitamin C and potassium, with the skin containing a good portion of the nutrients.
