There is a large deviation due to proteins and carbohydrates. Can this be due to variability in the ingredients?

This also has the issue with en:walnut being mapped to a fresh, rather than dried, walnut. Once this is corrected the estimate for Almonds (last ingredient) improves from 0 to 9%, but the overall nutrient difference is slightly worse. This is potentially because each ingredient has a relatively similar nutrient profile, so minor differences in the quality of nut used could significantly affect the results.
