'''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.
