Yes. A calorie is just a unit of measure for energy
calories.
Traditionally, this was measured in calories, or Calories (equal to 1000 calories - note the uppercase!). But the tendency is to use the official unit of energy - the Joule. This is the same unit that is used to measure any type of energy.
Kilo joules are used to measure the amount of energy stored in food.
A kilocalorie is not a measure of weight. It is a measure of energy
All foods 'have' kilojoules. A kilojoule is a measure of the amount of energy they can release when we 'burn' them. (You may be more familiar with calories, which are a different sized unit for the same thing). More exactly, all foods release energy when we use them in respiration, and this energy can be measured in kilojoules.
Kilojoules, often abbreviated as kJ, is a unit of energy used to measure the amount of energy contained in food. It is commonly used on nutrition labels to indicate the energy content of foods and drinks.

There is no SI Base Unit for energy. The unit for energy, the joule is a Derived Unit.
