Coffee Consumption Won’t Kill You But It Will Help To Mess You Up
Hey there is some good news for coffee drinkers. Coffee consumption does not increase the risk of death. But how does it affect coffee drinker’s quality of life?
If you have acid reflux you will want to avoid drinking coffee. This study[1] showed, by actually sticking a tube down people’s throats, that coffee consumption significantly lowered stomach pH and triggered acid reflux.
The same wasn’t found for tea with caffeine, which didn’t have much of an effect on acid reflux. Coffee does contain more caffeine than tea does so the researchers reduced the amount of caffeine in coffee down to the level tea contains and analyzed its effect on acid reflux.
The level of acid reflux was lowered by lowering the level of caffeine to that of tea, but the decaffeinated coffee still had a greater adverse effect on acid reflux than the caffeinated tea did.
So it appeared the composition of coffee itself had a greater impact on acid reflux than tea did, but the caffeine in coffee was also problematic.
Caffeine consumption has been associated loss of bladder control,[2] and with an increased risk of bone fractures in women.[3]
Caffeine consumption may aid in the deterioration of eyesight in people who have glaucoma,[4] and the consumption of coffee adversely effects the quality of sleep.[5]
The consumption of decaffeinated coffee would be less damaging to quality of life than caffeinated coffee would be, but caffeinated tea might be a better alternative to both.
The consumption of herbal teas that don’t contain caffeine would appear to be the best choice.
