   • 2013 June 29, “A punch in the gut”, in The Economist, volume 407, number 8842, page 72-3:

     Mostly, the microbiome is beneficial. It helps with digestion and enables people to extract a lot more calories from their food than would otherwise be possible. Research over the past few years, however, has implicated it in diseases from atherosclerosis to asthma to autism.

2. (physics, chemistry, obsolete) The gram calorie or small calorie, a non-SI unit of energy, equivalent to approximately 4.2 joules. This unit was widely used in chemistry and physics, being the amount of energy needed to raise the temperature of 1 gram of water by 1 °C.

使用する際の注意点

• Most scientific studies are now carried out using the joule (an SI unit).
• In nutritional contexts the term calorie refers to the kilogram calorie and the term kilocalorie refers to 1000 gram calories. Thus the two terms are equivalent.
• Calorie counters, such as those on fitness bikes, use the first, more modern, definition.
• European legislation now requires foods to be labelled with the term kilocalorie.
