I hate that supercow !
I find it very hard to calculate calories in real life. Looking up the calories of each ingredient, weighing the food... Anyone wants to write a short novel about this or can you recommend a site?
Simple: just buy a good kitchen scale and put in Excel all data from any box of food you have...
And for food that doesn't come in boxes use this site:
