Book excerpt: We have the responsibility to build a bridge to link computer revolution with nutrition and food science. So we are hoping that those students who would like to pass on this bridge could be able to see the whole picture of what the computer applications course is all about. Then next, how the computer enriches our specialization and what to expect in the near future about for updating development in that field. We wish this book to be in a great benefit to students of Nutrition and Food science and Dietetics programme. Dr Manal K Abdel-Rahman Dr Aly R Abdel-Moemin
