It could be either; but when you are talking about food, what is of interest is usually the energy content - meaning, chemical energy stored in the food.
Heat IS energy, and a kilocalorie is the energy required to heat one kilogram of water by one degree Celsius.

The energy stored in food is measured in units called?
Calories. Actually the unit called Calorie in food energy is the Kilocalorie, ie 1000 calories.
How energy content in food can be worked out?
A calorie is the amount of energy required to raise a volume of water a certain amount. This historically was determined by completely burning food surrounded by water. The Atwater system averages the components of food to determine a calorie count, because our bodies do not derive energy from certain types of food. In this system protein and carbohydrates add 4 kilocalories per gram to a food's total, whereas fat adds 9 kilocalories per gram. A kilocalorie is the energy required to heat one kilogram of water by one degree Celsius.
A college student produces about 100 kilocalories of heat per hour on the average what is the rate of energy production in watts?
116 W
In what units is heat flow measured?
kilocalories or kilojoules
What do scientists use to measure energy in food?
although not most accuratethe simplest way to test the energy content of foods is using a calorimeter, this is basically a insulated copper beaker filled with water. the item of food is burned under the copper cup. the change in temperature of the water is then taken. using the specific heat of water and copper it is possible to find how many joules of energy were added to the water and beaker. this value can then be converted into calories if desired

Which food item produces more heat energy and why?
Fats, higher calorie content.
Food into energy?
Food has an energy value, it is quoted in kilocalories (normally just called calories in nutrition). The mechanical equivalent of heat (calories) is 4.2 Joules per calorie, so it is obviously 4.2 kiloJoules per kilocalorie
The amount of heat that a food gives off is measured in?
Energy from food is measured in calories or kilocalories (or Calories with a capital "C"). On food labels, the Calorie (kilocalorie) form is used.A calorie is the amount of energy it takes to heat up one gram of water one degree Celsius. It is about 4.2 Joules.A Calorie (or kilocalorie) is the amount of energy it takes to heat up one kilogram of water one degree Celsius. It is about 4.2 KiloJoules.
How do scientist measure energy?
It is measured in food calories or kilocalories, (kcal)A kilocalorie = 1000 calories of heat.A bomb calorimeter is used to determine the heat content of foodstuffs.A representative sample of food is collected and 1 gram is placed in the calorimeter, the bomb is then filled with oxygen and placed in a vessel holding a measured amount of water. The sample is then burned in the bomb and the heat transferred to the water is measured, giving the total amount of heat released, in calories. This is then divided by 1000 to get food calories or kcals.

116 W
Explain why a food chain can have no more than three or four links?
As more organisms participate in a food chain, less energy is transferred from the prey to the predator. On average about 10% of the energy on one level is transferred to the next level. The other 90% is either lost as heat or cannot be digested. Example: A plant contains 10,000 kilocalories. The plant is eaten by an insect that will only gain 1,000 kilocalories of energy. Next, the insect is eaten by a fish which gains 100 kilocalories of energy. A bird consumes the fish and gains 10 kilocalories of energy. Finally, a mountain lion catches the bird and gains only 1 kilocalorie of energy.
What does kilocalories mean?
Kilo means 1,000, so kilocalories means a thousand calories.
In what units is heat flow measured?
kilocalories or kilojoules

What kind of energy is food energy converted to?
Food is chemical energy and is coverted into heat energy (body heat) and kinetic energy (being able to move) when you eat it.
