Isn't a potato a potato?100 grams of raw potato contains about 15 grams of starch and about two grams of protein, as well as some fiber, and the other 75 percent or so is water. After frying, potato fries will lose a lot of water, adsorption of some oil. Because more water is lost and less oil is adsorbed, the same weight of fries actually corresponds to more raw potato. Oil is high in calories, up to 9 kcal per gram, so the calories per unit weight of fried fries increase considerably. In general, French fries contain 300-400 kcal per 100 grams, and thin potato slices can reach 500 kcal. Of course, such calories are really high. Boiled potatoes, on the other hand, have almost 70 kilocalories, which is about 5-6 times more.

Thank you?
