Studies have shown that coffee is the main source of antioxidants in food.

The clinical blood lipid study of the Department of Medicine of the University of Oslo in Norway further confirmed that coffee plays an important role and is the main source of antioxidants in food. at the same time, it also determines that the absorption rate of antioxidants in different foods and the utilization rate in plasma are different.

Arabica coffee contains about 7% antioxidants, which are phenolic compounds and represent chlorogenic acid. Robusta coffee contains about 10% antioxidants, and chlorogenic acid is the most abundant polyphenols and major antioxidants in coffee. Coffee contains more antioxidants (7% Mel 10%) than some other common beverages. Recent studies have found that both tea and coffee have strong antioxidant properties, and the antioxidant effect of coffee is 4 times stronger than that of tea. If the coffee beans are roasted for too long and roasted very black, the antioxidants are almost completely destroyed. As a result, very black coffee contains no antioxidants but only caffeine.

Blueberries, pomegranates, green tea and red wine are foods and drinks rich in antioxidants, and studies since the 1990s have shown that they can prevent diseases. Recent studies have found that wine, beer and martinis also contain antioxidants. Since the 1990s, several articles have been published in the famous journal of the American Medical Association, showing that eating vegetables and fruits can prevent stroke. The researchers found that eating at least five servings of vegetables and fruits a day-especially citrus fruits and juices, green leafy vegetables and cruciferous vegetables such as broccoli, kale and turnips-reduced the risk of ischemic stroke by 30%. The study also found that drinking a glass of orange juice a day reduced the risk of stroke by 25%. The juice maker immediately added the discovery to the ad. Studies have also confirmed that reducing the intake of saturated fats and trans fatty acids and increasing the intake of vegetables and fruits can greatly reduce the risk of coronary heart disease. The antioxidants in coffee make a significant contribution to the prevention of cardiovascular disease and cancer, especially when a recent survey shows that Americans get more antioxidants from coffee than from other diets. Antioxidants are found in almost all fruits, vegetables and plants.
