Serving and food-state notes
The 36g household measure is the specific serving used on this page. For more repeatable tracking, weigh the fruit after removing stems and before adding yogurt, sweetener, or other ingredients.
Berry size and water content vary naturally, so a loosely filled or heaped cup can weigh more or less than 36g.
How this answer was calculated
For foods without sugar alcohols, this site uses net carbs = total carbohydrate − dietary fiber. “Net carbs” is a tracking convention, not a separate nutrient shown on the standard U.S. Nutrition Facts label. Individual glucose responses and dietary needs vary.
For this record: 14.5g total carbohydrate and 2.4g fiber per 100g are scaled by 0.36, then subtracted: 5.2g − 0.9g = 4.3g net carbs after display rounding.
