Well, I've been touting coffee for preventing dementia and Parkinsons for years.

The impact of coffee subtypes on incident cardiovascular disease, arrhythmias, and mortality: long-term outcomes from the UK Biobank
Abstract
Epidemiological studies report the beneficial effects of habitual coffee consumption on incident arrhythmia, cardiovascular disease (CVD), and mortality. However, the impact of different coffee preparations on cardiovascular outcomes and survival is largely unknown. The aim of this study was to evaluate associations between coffee subtypes on incident outcomes, utilizing the UK Biobank.
Coffee subtypes were defined as decaffeinated, ground, and instant, then divided into 0, <1, 1, 2–3, 4–5, and >5 cups/day, and compared with non-drinkers. Cardiovascular disease included coronary heart disease, cardiac failure, and ischaemic stroke. Cox regression modelling with hazard ratios (HRs) assessed associations with incident arrhythmia, CVD, and mortality. Outcomes were determined through ICD codes and death records. A total of 449 563 participants (median 58 years, 55.3% females) were followed over 12.5 ± 0.7 years. Ground and instant coffee consumption was associated with a significant reduction in arrhythmia at 1–5 cups/day but not for decaffeinated coffee. The lowest risk was 4–5 cups/day for ground coffee(I do 10-12 cups a day since neither dementia or Parkinsons prevention had amounts and I'm making sure I don't fall short.) [HR 0.83, confidence interval (CI) 0.76–0.91, P < 0.0001] and 2–3 cups/day for instant coffee (HR 0.88, CI 0.85–0.92, P < 0.0001). All coffee subtypes were associated with a reduction in incident CVD (the lowest risk was 2–3 cups/day for decaffeinated, P = 0.0093; ground, P < 0.0001; and instant coffee, P < 0.0001) vs. non-drinkers. All-cause mortality was significantly reduced for all coffee subtypes, with the greatest risk reduction seen with 2–3 cups/day for decaffeinated (HR 0.86, CI 0.81–0.91, P < 0.0001); ground (HR 0.73, CI 0.69–0.78, P < 0.0001); and instant coffee (HR 0.89, CI 0.86–0.93, P < 0.0001).
Decaffeinated, ground, and instant coffee, particularly at 2–3 cups/day, were associated with significant reductions in incident CVD and mortality. Ground and instant but not decaffeinated coffee was associated with reduced arrhythmia.
Coffee subtypes and associations with incident arrhythmia, CVD, and mortality. Caffeinated (ground/instant) but not decaffeinated coffee reduced the risk of arrhythmia. Both caffeinated and decaffeinated coffee reduced incident CVD and all-cause and cardiovascular mortality risks. CI, confidence interval; CVD, cardiovascular disease; HR, hazard ratio.
