Just like coffee beans, cocoa beans naturally contain caffeine ( 1, 2, 3). On average, an 8-ounce (240-mL) serving of coffee has 100 mg of caffeine. SummaryĬoffee is a brewed beverage that naturally contains varying amounts of caffeine, depending on the serving size and product brand. That’s less than half the amount of caffeine in a regular cup.Ī 2014 review study found that along with drinking regular coffee, drinking decaf coffee may reduce your risk of developing type 2 diabetes ( 7). One cup (240 mL) of decaf coffee contains 1–50 mg of caffeine, depending on the brand and serving size. However, it has reduced levels compared with regular coffee. In case you’re wondering, decaffeinated coffee still contains caffeine. You should read the nutrition label to be aware of the amount of caffeine per serving of coffee. For example, Starbucks’ 16-ounce (475-mL) Grande Vanilla Latte provides 170 mg of caffeine, while a Grande Blonde Roast of the same volume provides 360 mg of caffeine ( 8, 9). However, coffee products may contain very different amounts of caffeine. At this level, 4 cups of coffee per day will keep you within the safe limit of 400 mg of caffeine for healthy adults. On average, an 8-ounce (240-mL) cup of coffee contains about 100 mg of caffeine. Some studies exploring the relationship between coffee consumption and the risk of disease have suggested an increased risk of heart disease, while others have shown potential health benefits, including a reduced risk of type 2 diabetes ( 5, 6, 7). Whether coffee increases the risk of disease is controversial. Revered for its taste and aroma around the world, coffee is consumed for its stimulating effects, which increases energy levels, mood, and alertness ( 1, 2). Here are 10 common foods and drinks that contain caffeine.Ĭoffee is a brewed beverage prepared from coffee beans, which are a natural source of caffeine ( 1, 2, 3).
This is especially important to watch out for if you tend to experience negative side effects when you consume caffeine. These side effects include heart palpitations, anxiety, insomnia, and increased blood pressure and heart rate ( 1).īecause manufacturers add caffeine to some foods and drinks to promote increased energy, alertness, and mood, you may be consuming more caffeine than you think ( 1, 2). However, studies have observed mixed results, and some people may experience negative side effects at intakes of less than 400 mg per day ( 2, 4). One review study showed that 300 mg of caffeine per day in healthy pregnant women is safe, with limited data suggesting that 1.1 mg of caffeine per pound (2.5 mg per kg) of body weight in children and adolescents may be safe ( 2). Consuming up to 400 mg of caffeine per day has not been associated with adverse health effects in healthy adults ( 1, 2, 3). The Food and Drug Administration (FDA) generally recognizes caffeine as safe. The term “psychostimulant” means that it increases the activity of the nervous system ( 1, 3). Caffeine is the most commonly consumed psychostimulant substance in the world.
