How Many Calories Do Potatoes and Beans Have? A Nutritional Comparison

4 min read

A medium-sized boiled potato has about 87 calories per 100g, while boiled kidney beans contain around 127 calories per 100g. Understanding how many calories do potatoes and beans have depends heavily on the type and preparation method, revealing key differences for your diet.

Quick Summary

This article explores the calorie counts for various preparations of potatoes and different types of beans, outlining their key nutritional differences and health benefits.

Key Points

  • Calories Vary: A potato's calorie count depends heavily on how it's prepared, with added fats and oils significantly increasing the total.

  • Beans Are More Calorie-Dense: Per 100g, most cooked beans have a higher calorie count than plain boiled potatoes due to greater protein and carbohydrate density.

  • High in Fiber: Both foods are excellent sources of dietary fiber, but beans generally contain more per serving, promoting satiety.

  • Nutrient-Rich: Potatoes are a great source of potassium and Vitamin C, while beans are particularly rich in folate, iron, and magnesium.

  • Preparation Impacts Health: Opting for boiled or baked methods without excessive additives is the healthiest way to prepare both potatoes and beans.

  • Weight Management Tool: Despite differing calorie counts, both can be part of a healthy, balanced diet for weight management when portion sizes and preparation are considered.

  • Protein Source: Beans offer a significantly higher protein content than potatoes, making them a key component of plant-based diets.

The Caloric Content of Potatoes: Raw vs. Cooked

Potatoes are a versatile and nutrient-dense food, but their caloric value is not static. The calorie count of a potato changes significantly based on how it's prepared, primarily due to the addition of fats and other ingredients. A raw potato serves as a baseline, but few people eat them uncooked.

Raw Potato Calories

According to some nutrition data, a raw potato contains approximately 74-77 calories per 100 grams. They are mostly water and carbohydrates, with very little fat. This raw state provides a reference point for comparing other cooking methods.

Boiled Potato Calories

Boiling a potato is one of the healthiest and lowest-calorie cooking methods. A plain boiled potato contains about 75 to 87 calories per 100g, especially when cooked with the skin on, which retains more nutrients. The boiling process does not add any fat, so the potato's natural energy content remains consistent.

Baked Potato Calories

Baking is another low-fat cooking method, and a plain baked potato (flesh and skin) contains around 97 calories per 100g. However, the calorie count can skyrocket when toppings are added. The popular combination of a baked potato with baked beans contains hundreds of calories depending on portions and ingredients. For example, a single serving can be upwards of 450 calories with modest toppings or over 700 calories with added fats and cheese.

The Impact of Preparation on Potato Calories

Beyond boiling and baking, other cooking methods dramatically alter the calorie content. A simple fried potato has a significantly higher calorie count than a boiled one. Mashed potatoes also vary greatly depending on ingredients. A plain mashed potato might have around 89 kcal per 100g, but with added butter and milk, this can increase substantially. Frying potatoes, as in French fries, can increase calories by over 100 per 100g.

Calorie Breakdown of Various Beans

Beans are a fantastic source of plant-based protein, fiber, and complex carbohydrates. They are generally more calorically dense than plain potatoes due to their higher protein content. Here is a look at some common bean types per 100g when boiled:

Black Beans

Black beans are a popular choice in many cuisines and provide around 114 calories per 100g when cooked. They are also packed with fiber and protein.

Kidney Beans

Boiled kidney beans contain approximately 127 calories per 100g and are known for being a good source of protein and fiber.

Pinto Beans

Often used in Mexican and Southwestern dishes, cooked pinto beans offer about 122 calories per 100g and are rich in nutrients.

Navy Beans

Cooked navy beans are one of the more calorie-dense options, with about 127 calories per 100g, and are particularly high in fiber.

Nutritional Differences Beyond Calories

While calories are a primary consideration, comparing the full nutritional profile of potatoes and beans reveals different benefits.

Protein and Fiber

Beans generally have a higher protein and fiber content than plain potatoes per 100g serving. This makes them excellent for promoting satiety and aiding digestion. Potatoes, particularly with the skin, also contain fiber but a lower overall amount. For example, 100g of kidney beans has about 8.7g of protein and 6.4g of fiber, while 100g of boiled potato has only 2g of protein and 2g of fiber.

Vitamins and Minerals

Potatoes are an excellent source of potassium and Vitamin C, especially when prepared without high heat. Beans are rich in folate (Vitamin B9) and provide notable amounts of iron and magnesium. Both are cholesterol-free and contain valuable vitamins and minerals that contribute to a healthy diet.

How Many Calories Do Potatoes and Beans Have?: A Comparative Table

Food (per 100g, cooked) Calories Protein (g) Fiber (g)
Boiled Potato (skin-on) ~87 ~2 ~2
Mashed Potato (with butter) ~137 ~3 ~2
Black Beans (boiled) ~114 ~8 ~8
Kidney Beans (boiled) ~127 ~8.7 ~6.4
Pinto Beans (boiled) ~122 ~8 ~8

The Health Benefits of Potatoes and Beans

Both potatoes and beans offer significant health benefits when consumed as part of a balanced diet. Potatoes provide an easily digestible source of carbohydrates for energy, while beans contribute to sustained energy release due to their high fiber and protein content. The potassium in potatoes is essential for heart health and muscle function, while the folate in beans is vital for cell growth and metabolism. Together, they can form a complete and nutritious meal, offering a wide array of macro and micronutrients.

Conclusion: Making Informed Dietary Choices

When considering how many calories do potatoes and beans have, it's clear that beans generally contain more calories per 100g than simple boiled potatoes due to higher protein and carbohydrate density. However, the caloric intake from potatoes can quickly surpass that of beans depending on the cooking method and added ingredients. Ultimately, both are nutritious foods that can support weight management and a healthy lifestyle. The best approach is to be mindful of preparation methods and choose whole, minimally processed versions to maximize nutritional value. By understanding the specific calorie and nutrient profiles, you can make informed decisions that align with your dietary goals.
