Clinical studies have shown how green coffee extract helps to lose weight, prevents the onset of diabetes and helps reduce high blood pressure.
Green coffee extract contains chlorogenic acid, an antioxidant that promotes health in many different ways.
It additionally contributes to the slower release of glucose in the blood, so it is very useful in cases of type II diabetes.
It has also been shown to have an effect on the reduction of high blood pressure and on digestion. Green coffee extract consumption may facilitate weight reduction when combined with diet and exercise.
What is green coffee?
Green coffee extract is obtained from green coffee beans that haven't been toasted. Once toasted, the grains acquire their typical brown colour and can be used to make coffee, the most popular caffeine beverage.
The roasting process does not affect the content of caffeine in the plant, but it does destroy the majority of chlorogenic acid contained by the grains. This chemical element is also contained in bamboo, peaches, prunes and sunflower seeds.
Green coffee was presented as a weight-reducing supplement on the American TV programme "Dr. Oz Show" in 2012.
This programme cited a study published in the journal of "Applied Food Sciences", which showed how people who took green coffee, either with or without dieting and who exercised every day, managed to lose 10.5% of their body weight and 16% body fat in 22 weeks.
Some studies suggest that green coffee reduces the uptake of glucose in the intestine as well as blood sugar levels.
It has also been proven to reduce the output of glucose through the liver, causing the body to consume more fat reserves for energy.
Blood sugar levels and green coffee
Green coffee extract helps to control blood sugar in the treatment of type II diabetes.
In type II diabetes the body developes a resistance to insulin. Insulin is a hormone that instructs the body's cells to take glucose from the blood and metabolise it into useful energy.
The level of glucose in the blood increases after eating since the digestive system extract nutrients from food. Pancreatic insulin then makes the cells absorb glucose and use it, causing the blood sugar to return to its initial level.
With insulin resistance, cells do not respond to the insulin's signal to absorb glucose, so it accumulates in the blood, producing diabetes symptoms such as hunger or intense thirst and exhaustion.
Green coffee extract slows down the release of glucose into the bloodstream after eating.
Who is green coffee important for?
Green coffee extract helps one lose weight, since the caffeine it contains reduces the appetite.
Green coffee is also useful for regulating blood sugar levels.
It is believed that chlorogenic acid from green coffee produces a slower blood glucose release. As a result, it helps to relieve the symptoms of high blood sugar, which include urine increase, drowsiness, dizziness and problems with concentration or flatulence.
Type II diabetics that do not take anti-diabetic medicines and maintain balanced blood sugar levels in the blood with diet and exercise, can benefit from the health advantages offered by green coffee extract.
Green coffee and hypertension
Preliminary studies suggest that green coffee can be used in the treatment of hypertension, also called high blood pressure.
In 2006 the results of a study were published in the journal "Clinical and experimental Hypertension", in which green coffee extracts were applied to rats and humans, whose conclusions were later confirmed in a 2016 study.
These studies found that after taking green coffee extract a reduction in high blood pressure was brought about in both the rats and the humans. In animals and humans who only received a placebo, the blood pressure remained unchanged.
The studies concluded that the chlorogenic acid content in green coffee extract reduces high blood pressure. In addition, no side effects were observed.
Therefore, we recommend green coffee extract for the treatment of individuals suffering from hypertension.
Hypertension is a chronic disease that increases blood pressure in the arteries. An elevated blood pressure over an extended period increases the risk of developeing coronary artery disease, suffering a cerebrovascular attack, or the occurence of a chronic renal failure or an aortic aneurysm.
The chlorogenic acid in green coffee extract has antioxidant properties and reduces high blood pressure.
Who is green coffee beneficial for?
For people with hypertension (high blood pressure)
For people who want to lose weight
For people with type II diabetes
Does green coffee have any side effects?
Chlorogenic acid may have harmful effects if taken in high doses.
The possible side effects of green coffee are due to its caffeine content. Caffeine can cause increased urination, nervousness, stomach pain, headaches, and arrhythmias.
However, taken in the proper dosages, the health benefits of green coffee are more positive than the possible undesired effects. People who are sensitive to caffeine can use the decaffeinated preparation.
Green coffee interactions
There have been reports about possible interactions with green coffee.
Caution is advised for patients with diabetes who are taking insulin or other oral anti-diabetic agents, as green coffee may lead to hypoglycemia in this case.
This is because less glucose is absorbed and it also slows the release of glucose from the liver into the blood.
Diabetics should first consult their doctor before taking green coffee extract and control blood glucose levels more closely.
Benefits of green coffee
Green coffee is recommended for the treatment of hypertension and type II diabetes, as well as for those who wish to lose weight.
The recommended daily dose of green coffee is 93 mg or 185 mg for Svetol in the case of hypertension. In any case, the dose varies depending on each manufacturer of green coffee extract.
Reasons for taking green coffee extract
As an aid in weight loss diets
To avoid exhaustion after meals due to the delayed release of glucose
