Q I’ve heard that decaf coffee is no better than regular. What’s your view?
A I’m not a great fan of decaf coffee. While there’s no doubt about the harmful and energy-depleting effects of regular caffeine use, decaf still contains two of the three stimulants in regular coffee theobromine and theophyiline (Theobromine is the addictive stuff in chocolate). Both regular and decaf coffee also contain chlorogenic acid, which raises both cholesterol and homocysteine,[1] both of which are associated with an increased risk of heart attack.
A recent trial tested whether decaffeinated coffee would stimulate the nervous system the way regular coffee does,[2] thereby raising blood pressure and heart attack risk. It was found that even without the caffeine, a triple decal espresso still managed to trigger this undesirable effect. However, my real concern with decaf coffee is that, if you are trying to cut back on caffeine, drinking decal does little to stop your behavioral craving for the stuff. I’d suggest drinking something else entirely. Rooibosch tea is a great alternative, [3] as are the many delicious herbal teas on offer these days.
