Properties of green coffee
The coffee tree, Coffea canephora
and Coffea Arabica L
, is a tree of the Rubiaceae family, discovered in Ethiopia around the 10th century. During the Muslim conquests, coffee trees spread to neighboring countries. In the 15th century, coffee was grown throughout the Arabian Peninsula. Finally, in the 17th century, Westerners discovered the coffee bean from the Ottomans. The coffee tree was then found in the Antilles, in Latin America and extends today to the tropical regions of Africa, South America and Asia, in the hot and humid equatorial zone called the "bean belt".
Unlike black coffee, green coffee is not roasted and thus retains its natural virtues. The therapeutic properties of its green seeds are based on their chemical composition (1) rich in caffeine, trigonelline (80% lost if roasted), chlorogenic acid (2) (4 to 8% in green coffee compared to 1 to 3% in roasted black coffee), cafestol and kahweol, antioxidants absent from roasted coffee (3).
Coffee is recommended for its slimming action because it stimulates metabolism, reduces the absorption of carbohydrates and facilitates weight loss through its detoxifying action. It has diuretic and digestive effects by increasing the secretion of enzymes. It has tonic power that fights against states of fatigue and loss of muscular tonus. Its chlorogenic acid with antioxidant potential promotes the fight against cellular aging. Green coffee energises and boosts brain activity (4).
Because of its natural bitterness, green coffee is often consumed in capsules.
