Product

This product with four ingredients will be used to find the recipe. The ingredients states that 25% of each nut (walnut, hazel nut, cashew nut and almond) was used.

Data

Four scenarios:

Four nuts product
Nutrient Product Ciqual Expected Median Expected
Fat 58.0 58.7 56.2
Sat. Fat 6.4 5.95 5.78
Carbohydrates 6.4 11.09 13.5
Sugars 4.2 4.63 4.08
Fiber 8.5 7.93 7.16
Proteins 20.4 16.63 17.33
Salt 0.01 0.042 0.006

The nutritional values for the Ciqual ingredients.

Least squares fit

The table below present four fit results. This compares the Ciqual ingredients against the OFF median ingredients. And for the product itself and the calculated expected product.

The calculated results are pretty good.

The product results are way off. Negative values should not be allowed. Are the nutritional values of products so sensitive to the values of ingredients used? Or is this a big error in the product? The carbohydrates seem much too small. Increasing them to 10, will at least give positive values for the recipe, but nowhere near the expected results.
