I grew up in a family of coffee drinkers. As a child, I spent tons of time in local coffee shops or going on frequent Starbucks runs with my parents. I started drinking espresso in middle school and this became a daily habit when I was in high school. What kind of effects can caffeine consumption have on a developing body? The idea that caffeine stunts a child's growth has been debunked, because coffee consumption does not cause osteoporosis (Harvard Health Publishing, 2020). Additionally, bone growth cannot be reversed, so teens will not shrink once they start regularly drinking coffee. Many people shrink due to compression fractures from osteoporosis or the compression of disks above and below spinal bones, but this has not been linked to coffee consumption (2020). Some studies have linked coffee consumption to reduced liver disease, arrhythmia, Alzheimer's disease, and Parkinson’s disease (2020). With linked health benefits and no impact on bone growth, coffee seems to be a very beneficial stimulant for humans. However, caffeine tolerance in children is much lower than adults. Coffee and caffeinated beverages produced are commonly targeted towards adults, who typically tolerate high caffeine levels better. Children drinking coffee or caffeinated beverages can face health risks and potential reduced cognitive function (Perlman, Ph.D., 2021). The Department of Biomedical Engineering at the National University of Singapore conducted a study that demonstrated an association between children who regularly consumed large amounts of caffeine and lower scores of cognitive function than their non-caffeinated counterparts (2021). The categories included, cognitive flexibility, processing speed, episodic memory, working memory, inhibitory control, reading decoding, and comprehension. An important note is association is not equivalent to causation, so it is unfair to assume high consumption levels of caffeine lead to impeded cognitive abilities.
More research is being conducted on the impacts of coffee on child development and how this would impact the person through adulthood (McVay, 2020). For now, there is very limited research on the impacts of coffee and high doses of caffeine on children. Caffeine can disrupt sleep patterns and reduce sleep quality, which can be damaging for a child because quality sleep during adolescents is crucial for brain and body development (Lodato, 2013). Is it right to buy your children Starbucks beverages and highly caffeinated energy drinks? Everything can be done in moderation, and without significant data supporting detrimental effects to child development, it’s the parents decision.
