Study Finds Moderate Caffeine Intake May Lower Dementia Risk by 35% in Adults Under 75
A recent study has revealed that moderate consumption of caffeinated coffee or tea may significantly reduce the risk of developing dementia, particularly in adults aged 75 and younger. The research, which followed 131,821 nurses and healthcare professionals over a span of up to 43 years, found that those who consumed about 250mg-300mg of caffeine daily—equivalent to two to three cups of coffee—had a 35% lower risk of dementia. The study noted that the protective effects of caffeine level off beyond moderate consumption, with no additional benefits observed from higher intake. Interestingly, the study also found that individuals who consumed more decaffeinated coffee experienced faster memory decline, potentially due to pre-existing health conditions prompting a switch to decaf.
