People that regularly drink coffee live longer, and have a lower incidence of Parkinsons disease, prostate cancer, diabetes and heart disease (I wrote more specifically about coffee, heart disease and prostate cancer in 2009 here).
So, is coffee clean and compatible with clean living and well being diets? Absolutely YES! Thats great news, right? Okay, so there are some conditions... If you love a caramel latte or double mocha iced coffee with fresh whipped cream, I've got some bad news for you. Clean eating challenges artificial ingredients in your diet and sweeteners and sugars used in those kinds of beverages are usually over represented and are not good for your clean living diet. Most chain store coffees are considered unhealthy, so you are much better off, as with all clean eating, to prepare your coffee at home or trust a barista to make a quality coffee as black, short black or long black or if you are a milk drinker, try a cappuccino, latte or flat white prepared using almond milk or soy milk.
Clean eating is about eating more whole foods and eliminating processed foods from your diet because your body doesn't know how to effectively process processeed foods. An example of processed foods is white sugar, white flour and really anything with more than half a dozen ingredients, or ingredients your grand mother wouldn't have heard of. So, send your caramel syrups and sugar on a holiday and enjoy clean eating with coffee.
PS: If you are sensitive to caffeine, decaffeinated coffee is a great option for countering any side-effects of caffeine, like sleep troubles or over stimulation. But, don't turn to just any Decaf, you're still entitled to enjoy full flavoured decaf, processed naturally by the Swiss Water Mountain process!
