The potential benefits of green coffee, especially in the context of obesity, have been the subject of numerous studies. Research indicates that chlorogenic acids in it might aid in weight loss by reducing fat absorption and activating metabolism, says Dr Priyanka Rohatgi, Chief Nutritionist, Apollo Hospitals
Green coffee has recently surged in popularity as a superfood, lauded for its potential health benefits, particularly in addressing obesity. This burgeoning trend stems from the chemical composition of unroasted coffee beans, which sets them apart from their roasted counterparts. Green coffee is gaining attention for its richness in chlorogenic acids (CGAs), which are potent antioxidants believed to yield various health advantages.
The primary reason for green coffee’s appeal lies in its potential as a weight management aid. Studies have shown that chlorogenic acids may help in weight loss and management. CGAs, particularly one called 5-caffeoylquinic acid, can interfere with the absorption of carbohydrates in the digestive system, resulting in lower blood sugar levels and reduced fat accumulation. This mechanism is thought to contribute to weight loss by altering how the body metabolises fat and sugar. The roasting process alters the chemical structure of coffee beans, resulting in the reduction of chlorogenic acid content. Thus, black coffee tends to have lower levels of these beneficial compounds though roasting improves its aroma and flavour.
Furthermore, green coffee beans contain a lower amount of caffeine compared to their roasted counterparts. This could be advantageous for those sensitive to caffeine, allowing them to benefit from the chlorogenic acids without experiencing the jittery effects often associated with higher caffeine intake.
The potential benefits of green coffee, especially in the context of obesity, have been the subject of numerous studies. Research indicates that chlorogenic acids might aid in weight loss by reducing fat absorption and activating metabolism. A 2019 meta-analysis published in the Journal of Evidence-Based Complementary and Alternative Medicine pooled data from various trials and concluded that green coffee extract consumption could lead to modest weight loss. It suggested that the chlorogenic acid content might contribute to reducing body mass index (BMI) and body weight.
Moreover, the antioxidants in green coffee have been linked to improved heart health. CGAs are thought to have a positive impact on blood pressure and lipid levels. Their potential to improve vascular function and decrease the risk of cardiovascular diseases adds to the allure of green coffee as a health-boosting beverage.
The key difference between the two is that black coffee is oxidised and green is not. Both contain polyphenols that have strong antioxidant effects, potentially reducing your risk of heart disease. Also, they both have caffeine to increase alertness and focus and L-theanine, which releases stress and calms your body.
