This book contains portion size data for a wide range of food items and is invaluable for calculating nutritional intakes for the coursework! It generally gives small, medium, large and average protion sizes for foods included. A MAJOR shortcoming is that there is no index and some of the catagorisation of food items is not great, which can be very frustrating indeed!!! Hopefully this will be rectified in the next edition.
However, it is good for the purpose it serves and overall I would recommend this book for nutrition / nutrition and dietetics students.
