Very simple application to calculate energy (percent) produced from fat. The calcucation needs kJ and fat per 100g, and these numbers can in most countries be found on the food nutritional information label. Please comment (problems/requests) to make the app better.
See http://en.wikipedia.org/wiki/Food_energy for information about food energy.
