Children consume most of their caffeine intake from soda while adults consume the stimulant mostly from instant coffee mix, a study showed Tuesday.

According to a report released by the Ministry of Food and Drug Safety, soda topped the contribution level of caffeine in children aged 8 to 13 at 64 percent, followed by mixed drinks and ice cream, with 20 percent and 5 percent, respectively.

The contribution level of caffeine in adults was 71 percent from coffee mixes, followed by coffee extracts served at cafes and canned coffee products at 17 percent and 4 percent, respectively.

The average amount of daily caffeine consumption by all age groups was relatively low at 67.1 milligrams. The maximum daily dose of caffeine recommended for healthy adults is 400 milligrams.

The study was based on data from the annual state survey of public health conducted in 2010, officials said.
