When it comes to your health, green coffee brings lots of different benefits. Green coffee beans refer to the raw and un-roasted beans that originate from coffee fruits. Typically, green coffee beans are washed, dried and then roasted to create the coffee beans that most know and love.
But these unroasted coffee beans bring lots of benefits that you won’t necessarily find in your morning cup of brew, ranging from weight loss to lowered blood pressure, detoxification and even cancer prevention.
Green coffee beans rose to popularity after the iconic Dr. Mehmet Oz featured them on his television show, but unfortunately, they aren’t all that palatable. Therefore, they’re typically processed to derive green coffee bean extract, which is sold on the market as a nutritional supplement.
The following are the top 8 evidence-based health benefits of green coffee, that have been confirmed in actual medical research and studies.
1. Higher Antioxidant For Protection Against Disease
While roasted coffee beans do contain antioxidants, a large portion of antioxidant content is lost during the roasting and brewing process. Green coffee beans have been found to contain a much higher antioxidant content.
In fact, according to studies, green coffee bean extracts carry a score of 2,500 or higher on the oxygen radical absorbance capacity or ORAC scale. This measures the food’s ability to bring about a reduction in oxidative stress, which arises from aging, stress, dietary deficiency, exposure to chemicals, and other factors.
Notably, if you compare green coffee beans to an equal quantity of oranges or blueberries (by weight), the green coffee beans score 2,500, while the blueberries score 10 and oranges come in at just 3 on the ORAC scale!
2. Green Coffee Can Lower Blood Pressure
According to a 2005 study, the research revealed that males suffering from hypertension saw a significant reduction in systolic and diastolic blood pressure when they were given daily doses of green coffee bean extract over the course of four weeks.
In addition, a study published in 2006 revealed that subjects saw a reduction in blood pressure when given 140 milligrams per day of chlorogenic acid, derived from green coffee bean extract.
According to another study published in 2007, green coffee bean extract is more effective than roasted coffee when it comes to lowering blood pressure due to the lower levels of hydroxyhydroquinone, which is a roasting process byproduct.
3. Green Coffee Improves Detoxification
Green coffee beans have been found to be very effective in promoting detoxification; that is, cleansing the body of harmful properties.
Green coffee beans promote detoxification due to the presence of glutathione s transferase, an enzyme that serves as a catalyst in helping carcinogens to bond. Once bonded to the enzymes, the carcinogens and other harmful agents are flushed from the body.
4. Green Coffee Helps With Better Diabetic Control
Green coffee beans contain chlorogenic acid, which promotes more effective management of blood sugar levels in individuals with type two diabetes and those who are pre-diabetic.
University of Scranton professor Joe Vinson Ph.D led the research into green coffee bean extract’s impact on blood sugar levels in Type II diabetics, who number more than 26 million in the United States alone. Chlorogenic acid serves a similar function o as insulin and dietary changes, which are designed to help manage diabetes.
Studies have shown that those who ingested more chlorogenic acid saw a decrease in diabetes risk of fifty percent.
“There was a significant dose-response effect of the green coffee extract and no apparent gastrointestinal side effects… All doses of green coffee extract produced a significant reduction in blood sugar relative to the original blank glucose challenge. The maximum blood glucose occurred at 30 minutes and was 24 percent lower than the original with the 400 mg of green coffee extract and the blood glucose at 120 minutes was 31 percent lower,” Vinson explained of his findings.
5. Green Coffee Bean Extract Helps Boost Weight Loss
In addition to promoting more effective control of blood sugar levels, chlorogenic acid has also been found to promote weight loss, along with preventing diabetes in those who are pre-diabetic. Vinson found that individuals who took green coffee bean extract saw a reduction totaling 10 percent of their body weight in just 22 weeks.
According to Diabetes, Metabolic Syndrome and Obesity, the study revealed that individuals who took green coffee bean extract in doses of 700 milligrams per day and 1,050 milligrams per day saw an average of 18 pounds of weight loss over the course of 22 weeks.
Dr. Oz also tested the weight loss power of green coffee beans. A total of 100 women took part in the study; and those who took a dosage of 400 milligrams three times daily saw an average of one pound per week — that’s twice the amount of the weight lost by women who took a placebo. (The placebo group’s losses were attributed to the womens’ greater awareness of their diets, resulting from the food journal that was kept as part of the study.)
6. Green Coffee May Help Prevent Cancer
A study performed in 2011 revealed that the antioxidants, such as those contained in the chlorogenic acid found in green coffee bean extract, significantly inhibited the proliferation of cancer cells. The study was performed using liver cancer and colon cancer cells; it’s possible that this applies to other types of cancer as well.
So in short, chlorogenic acid from green coffee bean extract can prevent cancer with its free radical-combatting antioxidants, in addition to promoting greater detoxification.
7. Green Coffee May Prevent Rheumatoid Arthritis
The chlorogenic acid and other components of green coffee bean extract have been found to help prevent rheumatoid arthritis in those who are predisposed to developing the condition, while also preventing flares in those who are already diagnosed with the condition.
A study performed in 2012 revealed that chlorogenic acid serves as a potent anti-arthritic agent when given to male rats, limiting the adverse immunological response that can damage the body’s various organ systems. Research is now underway to determine if the same effect occurs in humans.
8. A Boost In Brain Health
Green coffee bean extract has been found to promote better brain health due to its impact on a protein called brain-derived neurotropic factor (BDNF), which has been found to play an essential role when it comes to learning, memory and behavior.
BDNF has been linked to many different conditions, such as dementia, Alzheimer’s disease, Parkinson’s disease, depression (including major depressive disorder), obsessive-compulsive disorder and beyond.
Studies have revealed that individuals suffering from depression have lower-than-average levels of BDNF. Green coffee bean extract serves to raise levels of brain-derived neurotropic factor, which is also elevated by successful depression treatments. BDNF levels decrease due to certain health conditions and as a natural result of aging.
BDNF is one of the few substances that can successfully cross the blood-brain barrier, which enables it to impact the brain chemistry in a positive manner. BDNF also impacts other body systems, such as the immune system and the cardiovascular system.
Green coffee beans can help you lose weight, promote detoxification, control your blood pressure, moderate your blood sugar levels and boost your brain health; it may also help prevent rheumatoid arthritis as well as certain types of cancer, all while delivering lots of helpful nutrients and antioxidants. So if you’re looking for a supplement with lots of benefits, try green coffee beans!
