If we know how the nutritional data for a product is reported, we can normalise that data. And with the normalised data we have a consistent dataset, which can be used to get the real nutritional values. We will normalise on the per 100g values with the formula: | If we know how the nutritional data for a product is reported, we can normalise that data.
