Medford, Massachusetts — A daily cup of coffee might do more than just boost your energy; it could also contribute to a longer life. A recent study from the Tufts University Friedman School of Nutrition Science and Policy suggests that while coffee consumption is generally associated with health benefits, the type and amount of additives can significantly influence mortality risk.
For many Americans, coffee is a staple, with half of the adult population reported to consume at least one cup a day. According to Fang Fang Zhang, the study’s senior author, understanding the implications of coffee consumption on health is increasingly vital. “The health benefits may be linked to coffee’s bioactive compounds,” Zhang stated, “but adding sugar and saturated fats can negate some of these advantages.”
The research highlighted that drinking black coffee or coffee with minimal sugar and fats was linked to a 14% reduction in the risk of death from all causes, compared to non-consumers. Conversely, those who heavily sweetened their coffee or added significant amounts of saturated fats experienced diminished health benefits.
Analyzing data from the National Health and Nutrition Examination Survey between 1999 and 2018, the study examined over 46,000 adults aged 20 and older, of whom 7,074 had died during the study period. The researchers cross-referenced mortality data with coffee consumption patterns, finding a clear trend: while coffee drinkers had a lower overall risk of mortality, high sugar and fat intake correlated with increased risk.
Interestingly, the study revealed that decaffeinated coffee drinkers did not show the same mortality benefits as those who drank caffeinated coffee. This finding raises questions about the components of caffeinated coffee that may contribute to improved longevity.
Bingjie Zhou, a key researcher in the study, emphasized the novelty of the findings. “Few studies have delved into the effects of coffee additives on mortality risk,” Zhou said. “Our research is one of the first to quantitatively assess how much sugar and fat people typically add to their coffee.”
The study aligns with established dietary guidelines that advocate for reduced intake of added sugars and saturated fats. As coffee remains a beloved beverage, these findings may encourage consumers to reconsider how they enhance their daily brew.
In essence, while coffee can be part of a healthy lifestyle, moderation in sweeteners and fats is crucial to maximize its potential health benefits.
