Drinking two cups of instant coffee mix products which contain high sugar contents takes up about 30% of the daily sugar amount WHO recommends, as sugar takes 50% of one instant coffee mix stick, 4.9~7.0g (average 5.7g)* per one serving size (one bag, about 12g)

* The highest sugar content product per one serving size is the ' Maxwell house original coffee mix(Dongsuh Food)' (7.0g), and the lowest sugar content product is the 'E-mart starmix instant mocha gold coffee mix(E-mart Company ltd.)'(4.9g). The highest reaches up to 1.4 times the lowest by products.

Drinking two cups of instant coffee mix products which have high caffeine contents equals to consuming 40% of the recommended daily intake(400mg), as caffeine content per one serving size is 40.9~77.2mg(average 52.2mg)*.

* The 'E-mart starmix instant mocha gold coffee mix (77.2mg) (E-mart Company ltd.)' contains the highest caffeine content per one serving size. On the other hand, the 'Maxim white gold coffee mix(Dongsuh Food)' (40.9mg) has the lowest level of caffeine, approximately twice lower than the former.
