The T-DDP score model proposed by Chen( 3 )
| Food items consumed | Energy percentage | Rating | Calculated score | Maximum limit of score |
|---|---|---|---|---|
| Cereals and tubers | 60·00 | 0·5 | 30·00 | 40·00 |
| Animal products | 14·00 | 2·5 | 35·00 | 40·00 |
| Beans and products | 5·00 | 2·5 | 12·50 | 18·00 |
| Vegetables and fruit | 5·00 | 2·0 | 10·00 | 15·00 |
| Added fats and oils | 9·00 | 1·0 | 9·00 | 10·00 |
| Nuts and oilseeds | 2·00 | 0·5 | 1·00 | 5·00 |
| Sweeteners | 5·00 | 0·5 | 2·50 | 5·00 |
| Beverages and seasonings | 0·00 | 0·0 | 0·00 | 0·00 |
| Total | 100·00 | – | 100·00 | 133·00 |
T-DDP score, traditional DDP score (DDP-China for 2000); DDP, desirable dietary pattern.
Example for calculation of the scores for food items: (i) energy percentage from the food × rating = score; (ii) add all scores of food items = total score; (iii) when the score for a food item exceeds the maximum limit of the score, the score must be counted at the limit. For example: when the energy percentage from cereals = 85, 85 × 0·5 = 42·5; since the maximum limit for cereals is 40 the score must be limited to 40, not 42·5 as calculated.
