All MIXED UP - Coffee lovers

Wow...I am a coffee drinker, it's ok coffee is not acidic when it gets into your stomach which has an acidic pH factor of around 1.5...7 being neutral...coffee is alkaline in nature. BUT...wow!!!! what is dangerous is the ADULTERATED mixture you get in the coffee you drink. Like the tasty chicken franks you eat which include all the chicken heads and legs 'dumped' in while processing, the coffee you drink could include coffee plant husks, stems, skins or stalks added before roasting takes place. So are you being conned?...wow...for your money's worth, you may be gulping down an impure mixture of coffee plus this plus that...you may opt to buy the real coffee beans and DIY if you are a coffee lover, that's a way out...or get the processed ones...instant coffee!
