Black coffee and expressos are two popular types of coffee, but each type provides different amounts of caffeine and antioxidants, depending on the portion and brewing method. When compared per ounce, expressos contain more caffeine and polyphenols than black coffee, and have strong antioxidant properties. According to Anna Blazhuk, a nutritionist at the University of Melbourne, Australia, The antioxidant properties in expressos help neutralize free radicals, support heart health and reduce inflammation, but consider small doses because expressos are often served in small amounts.
Caffeine and antioxidants: Benefits of each cup
Black coffee is made from roasted coffee beans in hot water, without added milk or sugar, has a characteristic bitter taste and strong aroma. An 8-ounce (240ml) cup of black coffee typically contains about 96mg of caffeine, which is higher than 63mg in an ounce expressedso. However, since expressos are served in small amounts, the overall caffeine content in a thick cup of coffee is often lower than that of a large cup of black coffee.
Antioxidants, especially polyphenols, play a role in neutralizing free radicals and supporting the body in fighting inflammation and cell damage. Espresso has a polyphenol content of 60 - 90 mg/oz, 20 - 40 mg/oz higher than black coffee. However, when drinking large cups, black coffee provides more total antioxidants due to the volume used.
Notes when enjoying coffee
The preparation greatly affects the quality of nutrition. Seed roasting, blending size, temperature and extraction time determine the polyphenol and caffeine content. Adding milk, cream or sugar also reduces antioxidant activity, while changing nutritional value.
According to Blazhuk, adults can safely consume 400 mg of caffeine per day, equivalent to 2 - 3 cups of 12-ounce coffee. Pregnant women should limit it to 200 mg/day. Choose the type of coffee that suits your taste and energy needs".
In general, express only suitable for those who want to enjoy a small serving rich in energy and antioxidants, while black coffee is ideal for large cups, providing more overall caffeine and antioxidants. Understanding each type helps coffee drinkers enjoy the full flavor and protect their health.
