Calculate the energy content of foods

While this calculator can be used a simple food calorie counter it is an integral part of an article on food labelling. The article provides an insight to the use of food labelling as a governmental policy 'tool' in the 'battle' against obesity and explains the science underlying the calculations.

Calculate the energy value of a food based on its chemical composition
Component % (g / 100 g)
Carbohydrate expressed as monosaccharide equivalent
Available carbohydrate (by difference or by weight)
Total carbohydrate*
Dietary fibre**
Organic acids
Polyols*** (e.g. mannitol, sorbitol, xylitol also known as sugar alcohols)

*Includes energy from dietary fibre. **Average food value used, foods enriched in dietary fibre should have their specific energy factors determined. *** Weighted mean value, individual polyols have specific energy values.
