How to calculate the Glycaemic Index of food?

This is basically impossible. The indices are measured experimentally, based on giving 10 subjects 50g of food and measuring their blood responses 2 hours later. So, unless a) I get a science degree to go alongside my non-existant maths degree, and b)I feed the girls on my team my M&S aubergine and lentil salad and then test them, it's unlikely I'll be able to work this out. Mostly because I don't like sharing food, and they think I get quite enough from them already, without actually giving me their blood.

M&S have done very well out of me today. So far, I have bought their 22% fruit muesli for breakfast, aubergine & lentil and tomato & mozzarella salad's for lunch, almonds, bananas, grapes and plums for snacks - and then ruined it all with two-for-one on jaffa cakes... But seeing as it's impossible to measure the GI of foods (plus, they virtually count as fruit anyway), we'll just assume it's all good!
