The aim of the study is to analyze the content of biology textbook for the intermediate stage through using the criteria of food technology and therapeutic nutrition, which is prepared by the two researchers. The method of content analysis has been adopted to accomplish the paper aim. The results show that the biology textbook (Human being and Health) for the third intermediate school is the highest in repetitions about (59) of (%53,3). The dietary habits have been emphasized within the textbooks of principles of biology for the intermediate stage where the repetitions are (70) with (%63,6). The researchers introduced some recommendations including the necessity to include biology textbooks concepts and ideas about food technology and therapeutic nutrition. Also, some suggestions introduced as conducting similar studies on the textbooks of biology for the secondary and primary stages.
