A survey was done in Northern Ireland in 2004. The nutritional content of 100g of different products sold by fast food restaurants was analysed and the results can be found at table 3 of the report.
A brief comparison very quickly summarised from this (per 100g):
Big Mac Meal - 13g fat, 26g carbohydrates, dietary fibre 1g, salt 0.7g, energy 1000kj
Pizza -10g fat, 23g carbohydrates, dietary fibre 1.8g, salt 1.5g energy 1000kj
Fish and Chips -13g fat, 21g carbs, 1.7g fibre, 0.5g salt, energy 1000kj
Chicken curry and fried rice - 6g fat, 15g carbs, 0.5 g fibre, 1.3 g salt, energy 576kj
Sweet and Sour chicken - 9g fat, 27g carbs, 0.5g fibre, .0.4g salt, energy 900kj
From the above it would seem the chicken curry is the healthiest and the kebab the worst.
Donner Kebab - 20.3g fat, 18.4g carbs, 0.2g fibre, 1.6g salt, energy 1300kj.
The above are just approximations taken from the table and the figures do vary between restaurants. The curries and Chinese meals probably vary more due to the larger variety of dishes.
