Energy-value-in-kcal-does-not-match-value-computed-from-other-nutrients: exclude more products

[CharlesNepote]

Describe the bug

In the Wikipedia article about Food Energy, we can read: "Some polyols, like erythritol, are not digested and should be excluded from the count".

For example, stevia sugars generally contain 90+g/100g of polyols and those are erythritol.
1000+ sweeteners are concerned, mainly stevia or 0 calories sugars: https://world.openfoodfacts.org/data-quality-error/energy-value-in-kcal-does-not-match-value-computed-from-other-nutrients/category/sweeteners

Calorie-free ingredients:

• erythritol (E968) (0.2 Kcal/g): https://en.wikipedia.org/wiki/Erythritol
• stevia (natural): https://en.wikipedia.org/wiki/Stevia
• acesulfame K (E950): https://en.wikipedia.org/wiki/Acesulfame_potassium
• saccharin (E954): https://en.wikipedia.org/wiki/Saccharin
• psicose, aka allulose (0.2 Kcal/g): https://en.wikipedia.org/wiki/Psicose

[CharlesNepote]

Many products with low energy (less than 13 Kcal or 55 Kj) are facing this error, probably due to rounded numbers.

Products with polyols and probably calories-free ingredients. Eg.

  etc.

• 92 446 products WITHOUT the quality error

-> hard to make conclusion, but I would say that there is no overlap between category having the error and small energy (i.e. products having low energy do not have necessarily the error).
