While technically a calorie is an unit of energy, there are some key distinctions assumed when we talk about food. First, when we say for example that an apple has 95 calories, what we really mean is that the apple has 95 kilocalories. Food energetic content is actually measured in thousands of calories. In chemistry, this distinction is typically made. Second, chemically an apple has energy stored in the fiber. If you were to burn the fiber you would get energy out of it.
