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.
