===Nutrition values issues===
Open Food Facts identifies some issues related to nutrition values. Some of them are '''very easy to solve''':
*[https://world.openfoodfacts.org/data-quality/energy-value-in-kcal-greater-than-in-kj Energy value in kcal greater than in kJ]
*[https://world.openfoodfacts.org/data-quality/nutrition-value-over-105-salt Nutrition Salt is higher than 100g per 100g]
*[https://world.openfoodfacts.org/data-quality/nutrition-value-over-105-carbohydrates Carbohydrate is higher than 100g per 100g]
*[https://world.openfoodfacts.org/data-quality/nutrition-value-over-105-fat Fat is higher than 100g per 100g]
===Nutri-Score quality===
Some products now have Nutri-Score printed on the front of pack. Some differs from our Nutri-Score calculation. We should take care about that:
*[https://world.openfoodfacts.org/nutrition-grade/e/label/nutriscore-grade-a Nutri-Score printed A but calculated E]
*[https://world.openfoodfacts.org/nutrition-grade/d/label/nutriscore-grade-a Nutri-Score printed A but calculated D]
*[https://world.openfoodfacts.org/nutrition-grade/c/label/nutriscore-grade-a Nutri-Score printed A but calculated C]
*[https://world.openfoodfacts.org/nutrition-grade/a/label/nutriscore-grade-e Nutri-Score printed E but calculated A]
*[https://world.openfoodfacts.org/nutrition-grade/b/label/nutriscore-grade-e Nutri-Score printed E but calculated B]
*[https://world.openfoodfacts.org/nutrition-grade/c/label/nutriscore-grade-e Nutri-Score printed E but calculated C]
*[https://world.openfoodfacts.org/nutrition-grade/a/label/nutriscore-grade-d Nutri-Score printed D but calculated A]
*[https://world.openfoodfacts.org/nutrition-grade/b/label/nutriscore-grade-d Nutri-Score printed D but calculated B]
*[https://world.openfoodfacts.org/nutrition-grade/c/label/nutriscore-grade-d Nutri-Score printed D but calculated C]
*[https://world.openfoodfacts.org/nutrition-grade/e/label/nutriscore-grade-b Nutri-Score printed B but calculated E]
*[https://world.openfoodfacts.org/nutrition-grade/d/label/nutriscore-grade-b Nutri-Score printed B but calculated D]
*[https://world.openfoodfacts.org/nutrition-grade/c/label/nutriscore-grade-b Nutri-Score printed B but calculated C]
There are many reasons why it can differ:
*the label in Open Food Facts does not represent the label printed on the package (easy to solve)
*the label is correct, but our calculation doesn't provide the same result:
**check the category,
**then check the nutrition facts: the issue is sometimes the lack of "fibers" information or the lack of "Fruits, vegetables, nuts and rapeseed, walnut and olive oils" percentage.
*it can be a software issue (quite rare but possible).

===Non-Food Products===
Some people are adding products which are not food: beauty products, books, pet food, etc. These products have to be moved to Open Food Facts side projects. Our AI (artificial intelligence) already identifies many cases. These cases are published in the [https://app.slack.com/client/T02KVRT1Q/CT2N423PA/thread/GCUD53J5R-1586349162.333800?cdn_fallback=2 #bot-image-alerts] channel on our slack space.
