What is Green Coffee?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Green coffee refers to the unroasted seeds of the Coffea plant, which are rich in bioactive compounds, particularly chlorogenic acids. These compounds are known for their antioxidant properties and potential health benefits, distinguishing green coffee from its roasted counterpart. Other names include: Arabica Green Coffee Beans, Café Marchand, Café Verde, Café Vert, Coffea arabica, Coffea arnoldiana, Coffea bukobensis, Coffea canephora, Coffea liberica, Coffea robusta, Extrait de Café Vert, Extrait de Fève de Café Vert, Fèves de Café Vert, Fèves de Café Vert Arabica, Fèves de Café Vert Robusta, GCBE, GCE, Green Coffee Beans, Green Coffee Bean Extract, Green Coffee Extract, Green Coffee Powder, Poudre de Café Vert, Raw Coffee, Raw Coffee Extract, Robusta Green Coffee Beans, Svetol.

Composition and Health Benefits of Green Coffee

Green coffee is notably higher in phenolic compounds compared to roasted coffee, which contributes to its health-promoting properties. The chlorogenic acids present in green coffee are associated with various health benefits, including antioxidant, anti-inflammatory, and lipid-lowering effects1 2 3. These properties make green coffee a popular choice for those seeking natural health supplements.

Cardiovascular Health

Research has shown that moderate consumption of green coffee can positively impact cardiovascular health. A study demonstrated that a blend of green and roasted coffee significantly reduced total cholesterol, LDL cholesterol, and triglycerides in hypercholesterolemic individuals, while also improving plasma antioxidant capacity and reducing blood pressure1. These findings suggest that incorporating green coffee into the diet may help mitigate cardiovascular risk factors.

Metabolic and Glycemic Effects

Green coffee has also been studied for its effects on glucose metabolism and insulin resistance. Long-term consumption of a green/roasted coffee blend has been shown to improve insulin sensitivity and reduce fasting glucose levels, which are critical factors in managing type 2 diabetes mellitus (T2DM)3 4. Additionally, green coffee extract supplementation has been found to improve glycemic indices and lipid profiles in patients with T2DM, further supporting its role in metabolic health5.

Liver Health and Antioxidant Activity

The antioxidant properties of green coffee extend to liver health, where it has been shown to protect against hepatotoxicity. In animal studies, green coffee methanolic extract demonstrated protective effects against liver damage induced by toxic substances, highlighting its potential as a natural therapeutic agent2. This protective effect is attributed to the high antioxidant content of green coffee, which helps reduce oxidative stress and inflammation.

Weight Management

Green coffee is often marketed for its weight management benefits. Studies have indicated that green coffee phenols may aid in reducing body weight and body fat percentage, although results can vary. The combination of green coffee with other compounds, such as oat β-glucans, has been explored for enhanced effects on appetite and satiety, although more research is needed to confirm these benefits7 9.

Adverse Effects of Green Coffee

Blood Pressure and Heart Rate: While some studies suggest that green coffee can reduce blood pressure, it is important to note that caffeine, a component of green coffee, can potentially increase heart rate and blood pressure in sensitive individuals1 6.

Gastrointestinal Issues: Consumption of green coffee may lead to gastrointestinal discomfort, such as stomach upset or diarrhea, due to its high chlorogenic acid content3.

Allergic Reactions: As with any plant-based supplement, there is a risk of allergic reactions, which can manifest as skin rashes, itching, or more severe symptoms in sensitive individuals3.

Impact on Blood Sugar Levels: Green coffee has been shown to affect glucose metabolism, which might be beneficial for some but could pose risks for individuals with certain metabolic conditions if not monitored properly2 8.

Kidney Function: While green coffee has shown protective effects against certain types of kidney damage in animal studies, its impact on human kidney function, especially in those with pre-existing conditions, requires careful consideration10.

How has Green Coffee Improved Patient Outcomes?

Improvements in Metabolic Health

Non-Alcoholic Fatty Liver Disease (NAFLD): GCE supplementation has been found to improve serum lipid profiles, reduce body mass index (BMI), and decrease fasting blood glucose levels in patients with NAFLD. However, it did not significantly affect liver enzymes or adiponectin levels1 6.

Type 2 Diabetes (T2D): In patients with T2D, GCE has been shown to reduce fasting blood glucose, improve insulin sensitivity, and decrease inflammatory markers like high-sensitivity C-reactive protein (hs-CRP)2 4. It also improved lipid profiles by increasing high-density lipoprotein (HDL) and reducing triglycerides2.

Metabolic Syndrome: GCE has been effective in reducing systolic blood pressure, fasting blood glucose, and insulin resistance in patients with metabolic syndrome. It also helped decrease waist circumference and appetite3.

Cardiovascular Health

Lipid Profile and Blood Pressure: Regular consumption of green coffee has been associated with reductions in total cholesterol, low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), and triglycerides. It also improved systolic and diastolic blood pressure, contributing to better cardiovascular health5.

Effects on Polycystic Ovary Syndrome (PCOS)

Lipid Profile: In women with PCOS, GCE supplementation led to significant reductions in cholesterol and triglyceride levels, although it did not significantly affect glycemic indices or insulin resistance9 10.

Green Coffee Mechanisms of Action

Antioxidant Activity: Green coffee exhibits strong antioxidant properties, which help protect against oxidative stress and damage in the body. This is particularly beneficial in protecting liver tissues from toxins, as demonstrated in studies with rats where green coffee extract improved liver function and reduced oxidative markers1.

Vasoreactivity and Blood Pressure: The chlorogenic acid in green coffee influences nitric oxide production, which improves vasoreactivity and can lead to antihypertensive effects. This has been observed in both animal and human studies, where green coffee extract improved blood vessel function and reduced blood pressure2 4.

Metabolic Regulation: Green coffee affects metabolic pathways by increasing the expression of PPARα and PPARγ genes, which are crucial in regulating lipid metabolism and insulin sensitivity. This action helps in managing metabolic syndrome by reducing blood glucose, triglycerides, and improving HDL cholesterol levels3 7.

Weight Management: Green coffee has been shown to reduce visceral fat and body weight, likely due to its influence on metabolic parameters and appetite regulation. It can enhance the expression of adiponectin, a hormone involved in fat metabolism, and reduce inflammatory markers5 6 7.

Cardiovascular Health: Regular consumption of green coffee can improve cardiovascular health by reducing cholesterol levels, blood pressure, and enhancing antioxidant capacity. These effects contribute to a lower risk of cardiovascular diseases4 8.

Common Complaints Associated with Green Coffee Use

Digestive Issues: While not explicitly mentioned in the provided studies, green coffee, like other caffeinated beverages, can potentially cause digestive discomfort such as stomach upset or acid reflux due to its caffeine content.

Caffeine-Related Effects: Green coffee contains caffeine, which can lead to common caffeine-related side effects such as jitteriness, increased heart rate, or insomnia, especially in individuals sensitive to caffeine.

Taste and Palatability: Green coffee is noted to have less acceptable organoleptic properties compared to roasted coffee, which might be a complaint for those who are accustomed to the taste of traditional coffee2 3.
