Understanding the Standard Blackberry Serving Size
For most people in the United States, a standard single serving of raw blackberries is defined as one cup. This measures approximately 144 grams by weight, making it easy to portion out with a standard measuring cup. This serving size delivers a wealth of nutrients in a low-calorie package, fitting perfectly into a balanced diet. However, it is worth noting that serving sizes can vary by region. For instance, an 80-gram serving (around 10 large berries) is considered one of your five-a-day in the United Kingdom. For most nutritional guidance and calorie counting purposes in the US, the one-cup measure is the most reliable.
