Roasting Coffee
Roasting transforms green coffee into the aromatic brown beans that we purchase, either whole or already ground, in our favorite stores. Most roasting machines maintain a temperature of about 550 degrees Fahrenheit. The beans are kept moving throughout the entire process to keep them from burning and when they reach an internal temperature of about 400 degrees, they begin to turn brown and the caffeol, or oil, locked inside the beans begins to emerge.
This process, called pyrolysis is at the heart of roasting. It is what produces the flavor and aroma of the coffee we drink. When the beans are removed from the roaster, they are immediately cooled either by air or water. Roasting is generally performed in the importing countries because freshly roasted beans must reach the consumer as quickly as possible.

COFFEE
A new review paper suggests that regular moderate coffee consumption may be associated with a reduced risk of heart failure,stroke,type 2 diabetes and some cancers, as well as reduce mortality, both for all-cause and cardiovascular deaths.
COFFEE AND TEA: PERKS FOR HEALTH AND LONGEVITY?
Purpose of review: Tea and coffee, after water, are the most commonly consumed beverages in the world and are the top sources of caffeine and antioxidant polyphenols in the American diet. The purpose of this review is to assess the health effects of chronic tea and/or coffee consumption.
Recent findings: Tea consumption, especially green tea, is associated with significantly reduced risk for stroke, diabetes and depression, and improved levels of glucose, cholesterol, abdominal obesity and blood pressure. Habitual coffee consumption in large epidemiological studies is associated with reduced mortality, both for all-cause and cardiovascular deaths. In addition, coffee intake is associated with risk of heart failure, stroke, diabetes mellitus and some cancers in an inverse dose-dependent fashion. Surprisingly, coffee is associated with neutral to reduced risks for both atrial and ventricular arrhythmias. However, caffeine at high doses can increase, anxiety, insomnia, calcium loss and possibly the risk of fracture.
Summary: Coffee and tea can generally be recommended as health-promoting additions to an adult diet. Adequate dietary calcium intake may be particularly important for tea and coffee drinkers.
