The number of calories in 1 pound of grapes depends on the type and specific variety of the grapes (red, green, or black), as well as their sugar content. Here’s a detailed breakdown:
1 pound (454 grams) of seedless green or red grapes typically contains around 300 to 320 calories.
Black grapes may have slightly more calories, about 320 to 340 calories per pound, as they are often sweeter.
Grapes contain about 62 to 69 calories per 100 grams, which can vary slightly depending on their water content and sugar levels.
Most of these calories come from natural sugars (fructose), along with small amounts of dietary fiber, vitamins (like Vitamin C and K), and antioxidants. Grapes are a healthy, low-calorie snack when consumed in moderation.
