What it is and what it contains
Green coffee is the seed of Coffea arabica, Coffea robusta, Coffea liberica, small trees of the Rubiaceae family, spontaneous in Ethiopia and cultivated in many regions of South America, Africa and Asia for the marketing of coffee.
The coffee plant is a tree that reaches about eight meters in height, evergreen, with leathery and shiny leaves and fragrant white flowers from which initially green fruits develop, red when ripe, which contain two seeds. Green coffee is represented by fermented or dried and unroasted seeds which contain, in addition to polysaccharides, proteins and lipids, about 5% of acid phenols (caffeic acid and chlorogenic acid) and variable percentages of caffeine, from 0.6 to 5 % depending on the variety but still lower than traditional roasted coffee.
Roasting modifies the composition of coffee seeds as during the process the polysaccharides and chlorogenic acid are degraded compounds responsible for the color and aroma typical of the coffee we usually consume, one of the most popular drinks in the world with a stimulating action. .
Although the data on green coffee are still few and conflicting, this product is considered a superfood with an antioxidant action and is traditionally used as a slimming in low-calorie diets and as a natural antihypertensive remedy.
Ownership, how to hire it and where to buy it
The seeds of the unroasted coffee fruit, known as green coffee, contain a high amount of chlorogenic acid, a substance that, together with caffeine, is the basis of the properties of unroasted coffee seeds. In fact, chlorogenic acid is attributed with slimming, antioxidant, anti-inflammatory and hypertensive properties, which are therefore useful for promoting weight loss during low-calorie diets, counteracting the harmful action of free radicals and lowering blood pressure.
Green coffee extracts are used to make food supplements in capsules or tablets, sachets or syrups. All green coffee-based products are readily available in herbal shops and pharmacies and are especially recommended to help reduce body weight, fat mass and body mass index in overweight people.
Potentially, green coffee could therefore represent a valid, economical and safe alternative for the treatment of obesity, a disease that is constantly increasing and associated with numerous diseases including cardiovascular and metabolic diseases, as well as some cancers. It being understood that in order to lose weight effectively and lastingly it is essential to follow a balanced and healthy diet and to carry out adequate physical activity, green coffee can contribute to losing weight more than just a diet, if it is taken as part of a diet low calorie intake.
The intake of green coffee then seems to decrease the absorption of carbohydrates in the intestine, thus reducing the amount of sugar in the blood and insulin peaks. This could be useful for preventing the onset or helping to control type 2 diabetes.
Furthermore, the chlorogenic acid present in green coffee can increase fat metabolism, lower blood pressure and total cholesterol and triglyceride levels and protect blood vessels, thus helping to reduce the risk of developing cardiovascular diseases such as heart attack and stroke. The protective effect of green coffee against this type of pathology also depends on the antioxidant and anti-inflammatory properties, since inflammatory processes and the action of free radicals are the basis of many diseases.
Finally, the presence of caffeine has a general tonic and stimulating action, so it can improve concentration and attention to work and study and make you more alert and energetic upon awakening or during the day. Since the amount of caffeine present in green coffee is lower than that contained in roasted coffee, the stimulating effect of green coffee is lower.
Contraindications and side effects
Coffee is one of the most consumed beverages in the world and is considered safe when drunk in moderation. Research on the side effects of green coffee extracts is limited, and although green coffee is believed to have a good safety profile, any long-term side effects are currently unknown. In the short term, prolonged or excessive intake of supplements containing green coffee can cause anxiety, agitation and palpitations due to the presence of caffeine.
However, the use of green coffee-based products is not recommended in case of hypersensitivity to one or more of its constituents and to people sensitive to the stimulating action of caffeine. The intake of green coffee is also contraindicated in pregnant and breastfeeding women, in children, in people suffering from kidney or liver diseases.
