It is easy to draw to many conclusions out of the limited data. The [https://en.wikipedia.org/wiki/Degrees_of_freedom_(statistics) degrees of freedom] concept describes what can be done. This will be explored here.

The limit will be the number of nutrients available for a product. Usually there are 7 nutrients, but when there is no fiber there will be 6 nutrients.

== Deterministic ===
With 7 nutrients we could theoretically determine a recipe of 7 ingredients. This becomes a problem with 7 equations with 7 unknowns. If there are more ingredients, the problem will be unsolvable.

For products with less than 7 ingredients, the problem will be easier to solve, especially when some ingredients are zero.

== No intercept constraint ==
Unfortunately a total free approach can give nonsense results. A total free approach does not assume anything.
