One question that sometimes comes up from our customers is "why does my recipe have 12% fat, I didn't expect that". Customers also want to be able to adjust their recipes to make them healthier or fit certain macronutritional profiles - so it's not just to calculate nutrition but also to understand how it got there and change it if possible. You want to be able to answer questions like "What's the best way to remove sodium?" and "What happens if we use less of a certain ingredient?".
