Excessive Coffee Intake May Compromise Bone Strength in Older Women

A research study spanning ten years involving nearly 10,000 women aged 65 and above indicates that high consumption of coffee could be associated with diminished bone density, whereas habitual tea consumption might correlate with slightly enhanced hip strength. The findings, published in the journal Nutrients, reveal that researchers from Flinders University monitored the coffee and tea consumption of participants alongside their bone mineral density assessments at the hip and femoral neck, areas significantly linked to the risk of fractures. While moderate coffee intake seemed benign, exceeding five cups daily was associated with lower bone density, particularly among those who also consumed alcohol. The researchers propose that the advantages of tea may stem from catechins that promote bone formation, whereas caffeine in coffee may hinder calcium absorption; however, they emphasize that the observed differences are modest and do not necessitate drastic changes in lifestyle.
