Potato (potato) is undoubtedly one of the most important and most common ingredients of the Polish diet. Over the years, there has been a false legend surrounding it that potatoes are high in calories and contribute to excess weight. In fact, boiled potatoes without any additives are a low-calorie product with a very high satiety index. This means that after eating them we feel full for much longer than after consuming the same amount of calories from pasta or rice. The problem with the calorie content of potatoes lies not in the vegetable itself, but in the way it is served - traditional Polish additions, such as butter, cream, cracklings or thick meat sauces, can double or triple the calorie content of the entire meal.
Our intelligent potato calorie calculator allows you to quickly calculate the energy value of a portion of potatoes depending on the method of thermal processing (raw, boiled in water, steamed, baked, jacketed), which is an invaluable help when balancing the menu to reduce body fat.
Potato nutritional values - potassium, vitamin C and resistant starch
Potatoes are an excellent source of many essential vitamins and minerals. Although citrus fruits are commonly considered to be the main source of vitamin C, in the Polish diet it is potatoes (due to the amount of their consumption) that provide the most ascorbic acid. In addition, potatoes are rich in:
- Potassium:A mineral crucial for regulating blood pressure and water and electrolyte balance. One large cooked potato can cover up to 20% of your daily potassium requirement.
- B vitamins (mainly B6):They support the functioning of the nervous system and protein metabolism.
- Resistant starch:If cooked potatoes are cooled (e.g. in the refrigerator overnight before eating in a salad), some of the starch they contain is converted into the so-called resistant starch. It acts like fiber - it is not digested in the small intestine, but becomes a medium for the beneficial intestinal microflora in the large intestine, lowering the glycemic load of the dish and reducing its real caloric value by about 10-15%.
Table of nutritional values and macronutrients in 100g of potatoes
The table below compares the nutritional values of raw and cooked potatoes in water (without added salt and fat):
| Nutrient | Raw potatoes (in 100g) | Boiled potatoes (in 100g) | Coverage (RDA) for cooked |
|---|---|---|---|
| Energy value | 77 kcal | 87 kcal | 4.3% (for a 2000 kcal diet) |
| Water | 79.0 g | 77.0 g | - |
| Carbohydrates | 17.5 g | 20.0 g | 6.7% |
| Including starch | 15.0 g | 17.0 g | - |
| Dietary fiber | 2.2 g | 1.8 g | 7.2% |
| Protein | 2.0 g | 1.9 g | 3.8% |
| Fat | 0.1 g | 0.1 g | 0.1% |
| Potassium | 421 mg | 379 mg | 10.8% |
| Vitamin C | 19.7 mg | 9.6 mg | 12.0% (some of it breaks down during cooking) |
The influence of thermal treatment on the glycemic index (GI) of potatoes
The glycemic index of potatoes varies greatly depending on how they are prepared. Hot, mashed potatoes have a high glycemic index (GI around 85-90), which causes a quick release of insulin in the blood and is not recommended for people with diabetes or insulin resistance. In turn, potatoes cooked in their jackets (with skin) have a lower index (GI around 65). Potatoes that are cooked and then completely cooled in the refrigerator have the lowest index (GI drops to approximately 50-55). This phenomenon results from the retrogradation of starch and the formation of the above-mentioned resistant starch.
Frequently asked questions (FAQ)
How many calories does one medium cooked potato have?
A medium-sized potato weighs about 90 grams after peeling. Such a single potato cooked in water without any additives provides about 75-80 kilocalories (kcal).
Do potatoes make you fat and should you give them up when losing weight?
No, potatoes themselves do not make you fat. They have a low caloric density (only 87 kcal in 100g) and a high satiety index, which helps control appetite. The key is to avoid fattening additives (sauces, butter, bacon) and moderation in portions.
What are the benefits of cooling cooked potatoes in the refrigerator?
Cooling causes starch to retrograde and form resistant starch, which is not absorbed in the small intestine. As a result, chilled potatoes have a lower glycemic index and provide fewer digestible calories, which is beneficial for people on a reducing diet and diabetics.
Can you eat raw potatoes or drink their juice?
Eating raw potatoes is not recommended due to the presence of solanine (a toxic glycoalkaloid found in abundance, especially in the green parts and sprouts) and difficult-to-digest starch. Raw potato juice is sometimes used in folk medicine for stomach ulcers, but it requires great caution.
Why do French fries have so many more calories than boiled potatoes?
The difference is due to the absorption of fat during deep frying. While 100g of boiled potatoes has 87 kcal, 100g of traditional fried fries has over 310-330 kcal, which is almost four times more.
