We assessed the availability of the Dietary Balance Guide（A） compared to the Four Food Groups（B） and Nutrient Intake calculated using a personal computer（C） as a teaching aid of meal planning lessons for senior high school students.　Two hundred and thirty-seven students （121 males and 116 females） of the second grade in senior high school took two of the three （A, B, and C） lessons and were then questioned about the availability of the material and method used in each lesson.
　The results were as follows:
1. Students answered that they could pleasantly study and were interested in either of the three lessons.
2. Dietary Balance Guide（A） was assessed as the most simple and easy to understand a nutritionally balanced meal, but difficult to be aware of the over-consumption of fat, meanwhile, they could easily be aware of the over-consumption of fat using the Four Food Groups（B） or using the personal computer（C）.
3. 3-4 servings of milk and milk products based on the Dietary Balance Guide was desirable for the students to achieve an adequate intake of calcium.
4. It was proved that there were the students who wanted to more deeply study using the Four Food Groups（B） or personal computer（C） rather than the Dietary Balance Guide（A）.
