Green coffee is a coffee bean of coffee fruit that has not been roasted. Since the roasting process of coffee beans can reduce the amount of chlorogenic acid, green coffee beans have higher levels of chlorogenic acid than regular coffee (fried coffee beans).
The benefits of eating green coffee
Extract from coffee beans has shown many health benefits, according to scientific research. The main ingredients that benefit are caffeine and chlorogenic acid, although some are affected by factors other than this compound.
According to a study published in March 2006 in BMC’s Complementary and Alternative Medicine, daily supplements of coffee bean extract can reduce body fat and weight, as well as a combination of fat in rat liver. In that study, caffeine and chlorogenic acid were seen as key compounds for weight loss. The chlorogenic acid found in coffee beans that are not fried can be digested and absorbed by humans as they are in the extract.
Decreasing high blood pressure
In addition to its effectiveness in weight loss, chlorogenic acid in green coffee can also lower blood pressure. A study published in Clinical and Experimental Hypertension in 2000 found that those who consumed 140 mg of coffee bean extract per day had lower blood pressure. At this time, no side effects have been reported by patients, so this drink can be called a safe way to reduce high blood pressure.
Improve mood and cognitive performance.
The caffeine in green coffee also has a positive effect on mood and the functioning of your brain. According to research published in the Nutrition Bulletin in February 2008, several studies have confirmed that caffeine can increase response time, alertness, memory, focus, patience, and a variety of other factors of cognitive performance. Researchers have found that the optimal intake of green coffee is 38-30 mg per day or four cups of bread coffee per second cup.
This coffee bean contains several antioxidants, which can reduce the effects of free radicals that can damage body cells. This preventive action makes you healthier by reducing the amount of damage to your body cells. According to a study published in the Journal of Agricultural and Food Chemistry in July 2004, the antioxidant chlorogenic acid in green coffee beans can prevent the growth of four types of cancer cells, so it can help prevent a variety of cancers.
Side effects of green coffee
Green coffee can be safe with a maximum dose of 480 mg per day, for a maximum of 12 weeks. Some coffee extracts are safe to use a maximum of 200 mg five times in 12 weeks. This is important to note, as green coffee also contains caffeine, similar to regular coffee. Thus, it also causes coffee-related side effects that are similar to coffee.
Caffeine can cause insomnia, nervousness and anxiety, abdominal pain, nausea and vomiting, increased heart rate and respiration, and other side effects. Drinking large amounts of coffee can cause headaches, anxiety, worry, ringing in the ears and irregular heartbeats.
