About Cup of coffee
Coffee is a brewed beverage made from roasted coffee beans, originating from Ethiopia and now widely consumed globally. It is integral to many cuisines, from Italian espresso traditions to American breakfast habits. A typical cup of black coffee is low in calories, containing approximately 2 calories per 8-ounce serving. It is a source of antioxidants like chlorogenic acids and also provides small amounts of micronutrients such as potassium and magnesium. Additionally, coffee contains caffeine—a natural stimulant that impacts alertness and cognitive function.
Health Benefits
- Caffeine improves mental alertness and supports cognitive functioning by stimulating the central nervous system.
- Antioxidants, such as chlorogenic acids in coffee, help combat oxidative stress and may reduce inflammation.
- Coffee contains small amounts of magnesium, which contributes to bone health and regulates blood sugar levels.
Dietary Considerations
Selection and Storage
Store coffee beans or grounds in an airtight container at room temperature, away from light and moisture. Grind beans just before brewing for optimal flavor.
Common Questions About Cup of coffee Nutrition
Does a cup of coffee have any calories or nutrients?
A plain, brewed 8-ounce cup of black coffee contains just 2 calories, 0 grams of protein, 0 grams of fat, and no significant carbohydrates. It also provides small amounts of essential nutrients like potassium (around 116 mg), magnesium, and niacin, though not enough to contribute significantly to daily requirements.
Is coffee compatible with a keto or low-carb diet?
Yes, plain black coffee is compatible with both keto and low-carb diets as it contains virtually no carbohydrates. However, adding sugar, milk, or cream can increase carb content, so many on keto choose unsweetened almond milk or heavy cream as alternatives.
What are the main health benefits and concerns of drinking coffee?
Coffee is rich in antioxidants and has been linked to lower risks of certain diseases, like Parkinson's, Alzheimer's, and Type 2 diabetes due to its bioactive compounds. However, excessive consumption can lead to side effects like insomnia, anxiety, or digestive discomfort. It's advised to limit intake to 3-5 cups per day, which equals about 400 mg of caffeine.
What is the recommended serving size for coffee?
A standard serving size of coffee is considered to be 8 ounces (1 cup), providing about 80-100 mg of caffeine per serving. For most people, up to 3-5 servings per day, or 24-40 ounces daily, is considered a safe limit based on caffeine guidelines.
How does coffee compare to tea in terms of caffeine and preparation?
An 8-ounce cup of black coffee contains about 95 mg of caffeine, while the same amount of black tea has around 47 mg. Coffee typically has a stronger, bolder flavor and faster preparation using brewing methods like drip or espresso, whereas tea is steeped and offers a wider variety of flavors and caffeine levels depending on the type.
