Do you mean you are looking for a dietary assessment tool in which you can compare your data with recommended intake per nutrient? If so, I think you should check WHO for recommendations or other national guidelines.
The dietary assessment tools that I can think of are mostly used to give the mean nutritional values of food products.
Thank you for your interest. I'm looking for a assessment tool to have quantitative results compare to compare them with recommendations so we can say at the end if the enfant has or hasn't a good diet.
An assessment or an index that will answer to this question.
Then I think assessment tool Nutri-Score is what you are looking for: https://www.foodwatch.org/en/news/2021/who-eu-wide-introduction-of-nutri-score-necessary/?cookieLevel=not-set .
