Most of our energy comes from the macronutrients macros , namely carbohydrates including sugar , fat, and protein in food we eat. Each of these macros contain the same type of energy, but in different quantities. Protein provides 4 calories per gram, same as carbs which give 4 per gram, whilst fat releases 9 kcal per gram.
Having covered the difference between kilojoules and calories, and figured out how to swap them, we can answer the question: does it matter which one we use? In theory, since both are standard units which measure energy, it ultimately should not matter. The most important aspect of both kilojoules and calories is that we can use either to record and compare what we consume or plan to consume at any given time. Your choice will probably come down to these factors:.
All physical nutrition labels in Australia list energy in kJ, and some list both kilojoules and Calories. Most digital English language resources list energy in Calories, and some list both. If you get most of your food health information from physical labels, the kJ seems to be the way to go. If you get most of your nutrition information from digital sources, then kcal probably works better.
How easy is it for you to use the label to understand how much energy there is in each food? Can you mentally or electronically with the aid of a digital app use the label effectively, on a day-to-day basis? Can you perform the same task more easily using digital alternatives to the nutrition label? If you find the digital option to be more convenient, you will probably want Calories for reasons outlined above.
Is it easy to convert units between kilojoules and Calories? How hard is to find a printed cross-reference table, or online conversion tool, or perform a mental calculation?
If it is easy to switch between Cal and kJ and vice-versa, then perhaps either are equally appealing. What units are usually listed in your recipe book, website or app? It is easier to become comfortable with the predominant unit of measure over time, rather than having to do conversions for each prepared meal or individual ingredients.
There is more to consider than just the food we eat. Does the equipment display kcal, kJ, or either? In Australia, we use kilojoules kJ to measure how much energy people get from consuming a food or drink. A kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. The food and drinks we eat provide energy, which is measured in kilojoules. Different ingredients in food and how they are prepared mean some have more kilojoules than others.
Larger serving sizes also mean more kilojoules. Some drinks are surprisingly high in kilojoules. You can find out how many kilojoules are in specific foods by checking the label nutrition information panel on packaged foods in the supermarket. When eating out or grabbing food on the run, check for kilojoules on the menu or food display tags.
