In an email, a follower of the Spanish newspaper El Diario asked whether green coffee has an effect on weight loss, and here we offer you the answer.
What is green coffee?
Writer Jordi Sabati said in his report, published in the Spanish newspaper ElDiario, that we should first know what green coffee is, it is coffee from coffee beans, or coffee extract, without previous roasting like coffee we usually drink.
In general, coffee is roasted for a number of reasons, first because of the concentration of caffeine when the water evaporates from the beans, and secondly because of the removal of the chlorogenic acid responsible for the green color.
And the writer indicated that this compound can be toxic when consumed in large quantities, especially if it is present in the doses of caffeine that we usually take every day, however, this compound contains some interesting properties when consumed in limited quantities.
What are the supposed characteristics of this coffee?
The author added that green coffee is known to cause – thanks to chlorogenic acid – a decrease in the level of glucose in the blood, in addition to speeding up the metabolism that will be added to that already caused by caffeine, and in addition, green coffee expands blood vessels, which reduces blood pressure. .
Based on these properties, green coffee – which should be consumed in appropriate doses – should have the ability to lose weight, as well as its role in lowering blood pressure, so it is recommended for people who suffer from high blood pressure and suffer from obesity, as it is recommended. Also diabetics and Alzheimer’s disease.
How effective is it?
The US National Library of Medicine database classifies natural preparations based on scientific evidence supporting a particular hypothesis or claim.
Based on these data, there is insufficient evidence to make a decision about the effectiveness of green coffee, whether with regard to high blood pressure or the treatment of obesity, and in both cases there are limited initial studies, according to the National Institute of Health.
In contrast, no trials have been conducted in the case of diabetes or Alzheimer’s disease.
Although preliminary research indicates that consuming green coffee extract daily for a period of 8 to 12 weeks can lead to a loss of between two and 4 kilograms of weight, the review has proven that the results are inconclusive.
In the event of high blood pressure, initial and limited research conducted in Japan indicates that consuming green coffee extracts that contain between 50 and 140 milligrams of chlorogenic acids daily for a period of 4 to 12 weeks may lower blood pressure in adults with mild hypertension. Healer.
It also helps reduce systolic blood pressure by 5 to 10 mm Hg.
In contrast, the diastolic blood pressure drops by 3 to 7 mm Hg.
Contraindications to consumption
Green coffee consumption is considered safe for healthy individuals, and in limited doses.
On the other hand, there are some exceptions and contraindications, and in this regard it is not recommended for pregnant women, as both caffeine and chlorogenic acid are transferred to the fetus.
In addition, people with high blood pressure who are undergoing treatment should not drink green coffee, either in the form of extracts or in the form of whole or ground beans, since the antihypertensive effect of chlorogenic acid may interfere with the treatment prescribed by their doctor, and if it is taken. This should be done under the supervision of a specialist.
The same thing happens in diabetics who are undergoing treatment, since the low blood sugar caused by green coffee can cause severe hypoglycemia and interfere with their treatment.
In addition, the diuretic and anticoagulant effects of chlorogenic acid can make existing ulcers bleed or put pressure on the kidneys in people with kidney problems.
