5 Proven Health Benefits of Coffee

1. Coffee may help to reduce the risk of Alzheimer’s disease

A study has shown that the consumption of higher quantities of coffee could help reduce the risk of Alzheimer’s disease. Researchers looked at whether coffee consumption impacted the cognitive decline rate of over 200 participants in ten years.1✅ JOURNAL REFERENCE

Results revealed a connection between coffee and some important markers associated with Alzheimer’s disease. The study discovered individuals without any memory impairments and having a higher coffee intake at the beginning of the study had a reduced risk of the transition to mild cognitive impairment, or the development of Alzheimer’s disease for the duration of the study.

Consuming more coffee provided positive results with regards to certain areas of cognitive function, particularly executive function which involves attention, self-control, and planning,. Higher consumption of coffee also appeared to be connected to the slowing of amyloid protein accumulation in the brain, a major factor in Alzheimer’s.

The study suggests an additional cup could provide better results if restricting to only one cup of coffee each day, although an ideal number of cups every day providing a beneficial effect wasn't able to be identified from this study.

Should the average cup of coffee consumed every day be 240g, the increase to 2 cups each day can potentially lead to a reduction in cognitive decline by 8% after 18 months. This could also lead to a 5% reduction in amyloid accumulation in the brain over the same period of time.

The amyloid accumulated clumps together and form plaques in Alzheimer’s disease that are toxic to the brain.
