 '''Solution or workaround:''' there is no solution. The producer did not mention that the products contains ingredients that should not be counted to compute the energy. For example, if a product is Stevia and contains 99g/100g of carbs, there should not be counted because stevia is not providing any energy.

+===When energy values are low (1-10 Kcal)===
 When energy values are low, there are often matching issues between the energy in Kcal and KJ. This often because producers are rounding the values.
 Eg.
-* https://world.openfoodfacts.org/product/3502110008459: In this example, 1 Kcal (rounded) => 6 KJ. Because 6 / 4.2 = '''1.428''', the producer is probably '''rounding 1.42 to 1'''.
