Health Line

Children only appeared to be more susceptible to caffeine than adults when, in fact, their is no difference to how it affects their metabolisms, a study showed.

The Australia New Zealand Food Authority (ANZFA), a regulatory body, said a study designed to help set the level for caffeine in the new trend of ‘energy drinks’ found the metabolism of caffeine in adults and children was similar.

" There is no reason to suspect children are more sensitive to the effects of caffeine than adults," Dr. Alex Proudfoot, Chairman of an ANZFA working group, said in a statement. "But further research will be required at doses typically consumed in the diet to examine whether similar withdrawal effects and physical dependency occurs in children."

The study found that even low doses of caffeine in drinks could affect people’s behaviour and become addictive in adults. Dietary levels of caffine at very low levels, such as between half a cup of tea to three cups of instant coffee, boosted energy, alertness, motivation and concentration.

Moderate to high doses of caffeine—over 4 cups of instant coffee – could lead to excitability and anxiety. "There may be some physical dependence and withdrawal effects at doses typically consumed in the diet," Proudfoot said. Withdrawal symptoms included headaches, fatigue, anxiety and increased work difficulties.

Proudfoot said the stud found no link between caffeine and cardiovascular disease and little evidence that caffeine at doses typically consumed in the diet contributed to high blood pressure.
