What is the difference between a calorie and a food calorie?
Calories can be broadly classified as
1. Large calories : This is also called as kilogram calorie, dietary calorie, nutritionist's calorie or food calorie.
"It is the energy required to increase the temperature of 1 kg of water by 1 degree C under 1 atmospheric pressure."
In conversion, 1kcal = 1 cal (in terms of large cal)
2. Small Calories : This is also called as gram calorie. (the other term you are refering in the question, 'calorie')
"It is the energy required to raise the temperature of 1gm of water by 1 degree C under 1 atmospheric pressure"
In conversion, 1Kcal = 1000 cal (interms of small cal)
So, when you are talking about 'calories', it refers to small calories.
And when you are talking about food calories or calories related to dietary facts, it refers to 'large calories', and remember the conversion holds.
A calorie is simply a measurement of an amount of energy. A food calorie tells you how much energy is in a food. The biggest difference is that in nutrition, the word calorie is used as short for kilo-calorie (or 1,000 actual calories), whereas in physics or other forms of science, a calorie is simply a calorie.
The difference between nutrient dense Calorie foods and empty Calorie foods lay in the nutritional content (Vitamin & Minerals) contained in the food. Foods such as whole grains, fruits, nuts, etc. contain high amounts of nutrition (Vitamin & Minerals etc.). These are referred to as nutrient dense foods. The term "empty Calorie" refer to foods such as candies, cakes etc. which have a high Calorie count compared to the essential elements contained within the food.
A heat calorie is the amount of energy it takes to heat 1 mL of water 1 degree celsius. A food calorie is 1000 heat calories. 1 food calorie is written as 1 C Answer A calorie is a calorie. Period! There is no such thing as a 'food calorie'! A calorie an obsolete unit from the cgsA system used to measure energy. Any form of energy. It is defined as the energy required to…
Assuming that you're talking about the difference between the calories listed on "Nutritional Information" labels on food, one "food calorie" is equal to 4.184 kilojoules, or 1000 calories in science (a "scientific calorie" being the amount of energy needed to raise one gram of water one degree Celsius).
Both Calorie and calorie are measurements of energy. 1 Calorie = 1000 calories Upper-case Calorie is used in nutritional terms and is sometimes also referred to as a kilocalorie to avoid confusing it with the lower-case calorie. Please see the related link for more details The Calorie (kilocalorie, kcal) is 1000 calories - a more useful unit and widely used.
A calorie is a unit of energy. Your body requires three macronutrients viz. protein, carbohydrates and fats. Protein and carbohydrates supply 4 calories per gram, while fat contains 9 calories per gram, making it much more calorie-dense. Empty-calorie foods have either very little or no nutrient content. They are also calorie-dense, meaning a small serving contains a disproportionately large number of calories eg. sugary food, alcohol, junk food etc.
calorie and Calorie . . . "small calorie" and "large calorie" . . . the common units of energy before the SI system of units was introduced. "small" calorie . . . "gram" calorie energy to warm 1 gram of water 1 degree C. 4.184 joules "large" Calorie . . . "kilogram" Calorie, "kilocalorie", the food calorie energy to warm 1 kilogram of water 1 degree C 1,000 small calories 4,184 joules
The difference between Calories and kilojoules is very much the same difference between metres and feet. They are just two different measures of the same thing, energy. It can be quite confusing though as often food is measured in kilojoules and exercise in Calories. This makes it tough to compare the two, but let's have a look at how it all works: 1 Calorie = 4.184 kilojoules (note that Calorie is with a capital 'C'…
No there's not. Except on the back of food packets it is called Kcal's instead of calories. This answer is wrong. A food, or dietary Calorie is equal to 1000 calories, which is 1 Kcal (kilocalorie). A capital C is also used to designate a Kcal, or 1000 small calories. A small calorie is designated by a small c, and is equal to the amount of heat required to raise the temperature of 1 cubic…
1 food calorie or Calorie or kilocalorie is equivalent of 1000 calories and thus 5 food calories is equal to 5000 heat calories. Answer A 'food calorie' is a unit of measurement that people in the food industry are either too lazy or too stupid to call a 'kilocalorie' (kcal). A calorie is a calorie. There is no such thing as a 'food calorie'. A calorie measures energy. Any energy. However, it is an obsolete…
Calorie is the unit of energy in CGS system of unit. Joule is the unit of energy in general in MKS system of units. Now we must get the relation between these two or tables connecting these. 1 cal = 4.18 J 1 K cal = 4180 J Suppose you rub you hands spening an energy of 4.18 J then 1 cal of heat will be produced. ============================================== calorie and Calorie . . .
