In order to maintain normal functions of the human body, in addition to the five nutrients, dietary fiber and phytochemicals are added; chlorogenic acid is one of the phytochemicals. Chlorogenic acid (CGA), also known as coffee tannic acid and eucommia chlorogenic acid, is a natural polyphenolic compound.
Many foods have chlorogenic acid, including apples, grapes, tomatoes, blueberries and other fruits; however, the content of chlorogenic acid in coffee is the highest of all substances, so it is also called coffee polyphenols.
Chlorogenic acid is also a key component of coffee aroma. It produces a chemical reaction through roasting to change the color of coffee beans and release a unique aroma and flavor. However, the heat resistance of chlorogenic acid is low, and more than 40 kinds of chlorogenic acid in coffee beans are easily destroyed by heat due to the high temperature and time of the roasting process; therefore, green coffee retains the most chlorogenic acid through low-temperature shallow roasting.
Cell studies have shown that chlorogenic acid can reduce cell death, reduce DNA fragmentation, and reduce reactive oxygen species and nitrogen species (ROS / RNOS) levels.
The International Journal of Medicine found in a human experiment that subjects who consumed coffee with a high content of chlorogenic acid had an average weight loss of 5.4 kg after 12 weeks. As for the group that drank coffee with a lower content of chlorogenic acid , The average weight is only 1.7 kg. In terms of body fat, the group with more chlorogenic acid in coffee decreased by an average of 3.6%, while the group with lower chlorogenic acid intake decreased by an average of 0.7%.
A study published in the 2010 International Coffee Science Conference pointed out that chlorogenic acid can interfere with the activity of lipase enzymes and inhibit the decomposition and absorption of fat. It also means that subcutaneous fat or visceral fat is not easy to accumulate in the body.
Dr. Joe Vinson of the University of Scranton in Pennsylvania published in 2013 that chlorogenic acid has the function of inhibiting glucose absorption and can also promote weight loss. This will be a major advancement in the treatment of type 2 diabetes.
As an active ingredient in coffee, chlorogenic acid can prevent diabetes and improve blood sugar control in normal, pre-diabetic and diabetic patients. In the study, overweight or obese people who used chlorogenic acid extract lost about 10% of their body weight within 22 weeks.
The Journal of International Medical Research also found that coffee rich in chlorogenic acid induced a 6.9% decrease in glucose absorption.
Vascular power refers to the power of blood vessels to regulate contraction and expansion in order to transport the necessary amount of blood to the necessary part. Irregular diet, aging, and various reasons cause blood vessels to harden, which makes the nerve function that controls vasoconstriction and expansion low, and blood flow is blocked, which makes it difficult to transport necessary oxygen, nutrients, heat, etc. to cells, and carbon dioxide in the body. Old waste materials cannot be recycled and metabolized. Cold hands and feet, dry skin, cardiovascular disease, etc. follow suit.
For vascular health, in addition to re-examining your diet, sleep time and other lifestyle habits, consuming chlorogenic acid can effectively improve vascular power. "Clinical and Experimental Hypertension" in a clinical experimental study found that the intake of chlorogenic acid has an anti-hypertensive effect. The metabolites of chlorogenic acid can attenuate the oxidative stress (reactive oxygen species) response, improve the endothelial function of arteries and blood vessels and lower blood pressure.
When the human body is inflamed, many oxidative reactions are produced in the body, which destroys diseased cells, but also damages otherwise healthy cells. The antioxidant capacity of chlorogenic acid improves inflammation. The National Institute of Public Health of Finland (National Institute of Public Health) After tracking the coffee drinking habits of 19,000 Finns for 15 years, it was found that people who drink more than 3 cups a day suffer from rheumatoid arthritis at twice the rate of people who drink less than 3 cups.
In 2017, the "Liver Pathophysiology-Therapies and Antioxidants" document pointed out that the ingredients in coffee contain chlorogenic acid, which has anti-fibrotic properties and is related to the regulation of transforming growth factor, connective tissue growth factor and antioxidant; coffee can also Inhibit the reproduction of hepatitis C virus.
Drinking coffee in moderation daily can help resist the oxidative pressure of body tissues and inhibit the formation of carcinogens. Japan has conducted a study on the population of 90,000 Tokyo metropolitan people. The study found that drinking coffee for hepatitis B and C patients has a dose relationship with reducing the risk of liver cirrhosis and hepatitis. Drinking a cup of coffee a day can reduce the risk of liver cirrhosis and hepatitis by 78%.
Among 39 elderly people, 3 cups of coffee rich in chlorogenic acid can improve mood.
Research from Kobe Pharmaceutical University in Japan pointed out that chlorogenic acid protects the skin from ultraviolet (UVB) damage, Prevents melanin precipitation, prevents dark spots, and resists active oxygen substances to keep the skin elastic and shiny; it can also accelerate the skin's metabolism, accelerate the skin to expel dead keratin, and reduce the dark circles caused by poor circulation.
