It is more energy efficient to raise lambs in New Zealand and ship them to the UK than to raise them in the UK, because New Zealand lamb farming is more energy efficient.

The Glycaemic Index Diet
The gi (or glycaemic index) diet is based on the gi index, a list of types of food and a score illustrating the ease with which the energy of the food type gets converted to glucose in your system. The believe is that slow acting types of food (ie those foods with a low Gi score), suppress your appetite and mean that you can eat fewer food without being miserabl;e.
It is also beneficial for people with diabetes, as the low GI food types are beneficial in preventing rises in blood glucose levels.
