Re: Why has a peanut more energy than a marshmallow?

Greetings,

Thanks for submitting your question about calorimetry to the MadSci Network. We have a few answers in our archives that should help address your question. Take a look at answer 1100670148.Gb, and answer 1068860302.Bt, about the caloric content of fats and carbohydrates.

In addition, you can also use our search engine to locate answers containing the words calories fats carbohydrates.

As you will see from these answers, fats contain more caloric energy per gram than carbohydrates. Pure fats contain about 9 kilocalories (also known as Calories with a capital-C) per gram, while pure carbohydrates and pure proteins contain 4 kilocalories per gram.

Lets compare the nutritional/caloric content of a Marshmallow with the nutritional/caloric content of dry-roasted peanuts without added salt and with added salt.

From this, you can see that one serving of marshmallows is 50 grams, of which 0.2% is fat, 1.8% is protein, and 81.2% is carbohydrates, and which contains 159 calories. So one gram of marshmallows contains 3.18 Calories.

In contrast, dry roasted peanuts are 24% protein, 22% carbohydrates, and 72.5% fat, so that one gram of dry-roasted peanuts contains 5.85 Calories!

Keep asking questions!
