The number of Calories in a food is determined by using an apparatus called a calorimeter. A sample is placed in a steel container within the calorimeter and water is added to fill a surrounding chamber. When the food burns, the heat released increases the temperature of the surrounding water. By calculating the heat in kilocalories (or Calories) absorbed by the water, we can determine the caloric content of the food.
The caloric values are the kilocalories per gram of the three types of food: Carbohydrates, fats, and proteins. These values are listed below.
Food Type Carbohydrate Fat (lipid) Protein
Caloric value 4 kcal/1g 9 kcal/1g 4 kcal/1g
If the composition of food is known in terms of the mass of each food type, the caloric content
(the total number of Calories) can be calculated.
Kilocalories= g x kcal/g
Sample problem.
How many kilocalories are in a piece of chocolate cake that contains 35g of carbohydrate, 10g of fat, and 5g of protein? Round the final answer to the nearest tens place.
Carbohydrate: 35g x 4 kcal/1g = 140 kcal
Fat: 10g x 9 kcal/1g = 90 kcal
Protein: 5g x 4 kcal/1g = 20 kcal
Total caloric content: 250 kcal
High caloric value for the amount of food you're actually eating. Compare fried chicken to the same food mass of celery sticks. High caloric value for the amount of food you're actually eating. Compare fried chicken to the same food mass of celery sticks.
high caloric food
Yes, foods are organized into groups in MyPyramid by their caloric content.
A high peroxide value in a food or oil sample indicates that there are high levels of oxidation present. This can lead to rancidity and off-flavors in the product. It is used as an indicator of the freshness and quality of the sample.
Fat has the highest caloric content by weight with 9 Kcal/gram while alcohol comes in second with 7 Kcal/gram. Carbohydrates and proteins carry 4 Kcal/gram. Thus the most caloric food by weight would be pure fat, such as oils and lard.
Salt is not a caloric food.
It depends on your nutritional needs based on how quickly your body metabolizes and the kind of diet you want, but generally: 45% of your caloric intake should be from carbs, 30% protein, and 25% fat, based on a 2,000 calorie diet.
No, corn is not a suitable food for guinea pigs as it's very starchy and too caloric with very little nutritional value. Avoid corn and any guinea pig food that contains it.
There is no scale that measure the calories in food. However, you can use this site to look up caloric information: www.caloriecount.com.
Dairy food is a high caloric, high fat and high fat food group. These are preferred for a variety of endless reasons.
Not any more than any other caloric food.
The modern term for caloric is "calorie." It refers to the unit of measurement used to quantify the amount of energy provided by food and drinks when metabolized by the body.
