Bean there, age slower?
Coffee link to slower biological aging in those w mental illness–to point
Study says up to 4 cups may slow aging signs — commenters clap back, cheer on, and meme the beans
TLDR: Study links up to four cups of coffee with longer telomeres (slower aging) in people with bipolar disorder or schizophrenia. Commenters are split: skeptics dunk on self-reported data and missing caffeine details, while a diagnosed user swears coffee steadies symptoms; everyone agrees it’s intriguing but not proven.
A new King’s College London study says people with bipolar disorder or schizophrenia who drink up to four cups of coffee a day have longer telomeres — a sign of slower biological aging — roughly like being five years “younger.” Go past four cups, and the benefit fades. That was enough to send the comments into a caffeine-fueled brawl. Skeptics came in hot: one user blasted it as “completely worthless” without actual caffeine measurements, pointing out the study relied on self-reported coffee habits and didn’t track brew type. Another mocked cherry-picking with a deadpan zinger about needing people “born on Mondays between 07:00 and 11:00.” Meanwhile, a diagnosed reader shared a powerful personal take: for them, coffee is basically medicine — “like breathing air” — and skipping it triggers symptom flare-ups. Meta-commentators rolled their eyes at yet another java headline — “Liking coffee linked to …” — while others pleaded for nuance: correlation isn’t causation, and even the authors say more research is needed. Still, the idea that an everyday habit could help a group facing shorter life expectancy has people buzzing. For context, the study landed in BMJ Mental Health and nods to the NHS cap of roughly four cups. Science says “maybe.” The comments say “prove it,” “pour it,” and “pun it.”
Key Points
- •Coffee consumption up to four cups/day was associated with longer telomeres in adults with schizophrenia, bipolar disorder, or psychotic depression.
- •The strongest association was observed at three to four cups/day; consuming more than four cups was linked to shorter telomeres than the three-to-four-cup group.
- •The association equates to an approximate biological age five years younger compared with non-coffee drinkers.
- •Analyses adjusted for age, sex, ethnicity, medication, and tobacco use; coffee type and caffeine concentration per cup were not recorded.
- •Data came from 436 participants in the Norwegian TOP study (2007–2018); findings were published in BMJ Mental Health and align with NHS guidance (≤400 mg caffeine/day).
