Coffee drinkers may be getting more than an energy boost. A Finnish study found that people who drank more coffee tended to have less total and abdominal fat, more muscle, and healthier metabolic markers despite having similar BMIs. Higher coffee intake was also linked to lower levels of certain amino acids associated with insulin resistance and type 2 diabetes risk.
Does it matter if the coffee is decaf or caf?
Surprisingly there is a inverse relationship in dementia risk. Normal coffe has lower and Decaffeinated has a slightly higher risk. Source
Maybe it’s like tea where the other compounds curb the effects of caffeine. So decaf would stunt you long term.
He says it’s really unclear why this is happening. It might be that people who already have some health problems stop drinking caffeinated and switch to decaf. But it’s clear that caffeine in tea and coffe is healthy with the greatest effect of up to ~3 cups.
oh, it’s just correlation. Honestly us human jump to so many conclusions that I feel like the only things we can begin to trust are peer reviewed evidence of causation.
