Black coffee contains no significant amounts of the macronutrients, fat, carbohydrate and protein and therefore contains only 1-2 kcal per 100ml1.
However, the final nutrition profile of a cup of coffee will be affected by several factors:
- The addition of milk, cream, sugar or other sweeteners to taste will affect the final nutritional value and may increase the calorie content.
- The variation in cup sizes used across Europe may alter the nutritional value.
Black coffee contains a number of micronutrients, notably potassium, magnesium and niacin. The sodium level is very low. The data below provides the micronutrients nutritional profile of 100mls of medium strength black coffee1.
The type of water used in preparation (i.e. hard or soft water) may influence the micronutrient content of a cup of black coffee, particularly in relation to calcium and magnesium levels. Slight variations in composition may occur due to origin, growing conditions, blend composition and processing of the coffee.
Coffee and Hydration
Black coffee contains in excess of 95% water and, according to the latest research, when consumed in moderation, it does not lead to dehydration. Therefore, a cup of coffee contributes to the daily fluid balance.
- Studies have shown that caffeine consumption, up to the equivalent amount found in 5 cups of caffeinated coffee, does not cause dehydration2.
- There may be a mild short-term diuretic effect from caffeine but this is not strong enough to outweigh the benefits of fluid intake from coffee consumption2.
- Research suggests that moderate caffeine consumption does not alter total body water and fluid distribution3 and drinking a variety of caffeinated beverages, such as coffee, can contribute to meeting the body’s requirement for fluids4.
- The body of evidence available suggests that advice to abstain from coffee drinking to maintain fluid balance is unfounded.
