General tips
When you are travelling, you should have a quick think about where your food has come from. When/if it is locally produced, your food is likely to be tastier, better for the local economy and fresher.
A local veg box shared between friends is a few quid a week, and the perfect way to slash your food miles while eating good food. So if you're self-catering at university why not try a doorstep delivery from one of the many veg box scheme providers?
Diet types
The Glycaemic Index Diet
The gi (or glycaemic index) diet is based around the gi (or glycaemic index), a chart showing types of food and a score representing the ease with which the carbohydrates in the food gets changed to glucose in your body. The claim is that slow acting food types (ie those with a low Gi score), suppress your appetite for longer and help you to consume less food without being miserabl;e.
It is also very good for people with diabetes, as the low GI food types are useful in preventing increases in blood glucose amount.
