Cognitive decline, particularly due to Alzheimer’s disease, is a major public health problem in older adults. Therefore, finding ways to maintain cognitive function is important. To investigate the impact of different levels of tea and coffee consumption on cognitive function in older adults, scientists from Murdoch University, the University of Western Australia, Edith Cowan University and Alzheimer’s Research Australia analyzed data from 8,715 participants aged 60-85.
Participants were free of dementia at the start of the study and were followed for an average of just over 9 years.
Participants reported their coffee and tea intake and were divided into three groups:
Drinking 1-3 cups of coffee a day helps the elderly fight cognitive decline

- Never drink tea or coffee.
- Drink in moderation, 1-3 cups of coffee or 1-3 cups of tea per day (240 ml/cup).
- Drink 4 or more cups of coffee or 4 or more cups of tea per day.
Participants underwent at least two cognitive assessments during the study.
Results found:
For coffee: Drinking 1-3 cups a day is best for protecting against cognitive decline in older adults, especially reasoning and problem-solving abilities, according to News Medical.
Conversely, drinking four or more cups of coffee per day is counterproductive, accelerating cognitive decline.
For tea: Drinking tea at any level, 1-3 or 4 or more cups per day, helps protect against cognitive decline in older adults, compared with not drinking.
Previous analyses have shown similar results. One study found that consuming up to 2.5 cups of coffee a day reduced the risk of cognitive disorders, while the benefits of tea increased with each additional cup, with each additional cup reducing the risk by 11%, according to News Medical.
Another meta-analysis found that low levels of coffee and green tea consumption were protective against cognitive decline and dementia.
