Approximately 94 percent of households in the United States eat strawberries, notes a fact sheet on the University of Illinois Extension website. And not just a few strawberries -- an average of almost 8 pounds of strawberries was eaten per person per year as of 2012. Strawberries are low in calories and a good source of vitamin C, making them a nutritious fruit choice.
The number of calories in a strawberry depends on the size of the strawberry. A small strawberry that is about 1 inch in diameter has just 2 calories. A medium strawberry, which is about 1 1/4 inches in diameter, has 4 calories, and a large 1 3/8-inch-diameter strawberry has 6 calories. You can eat a cup of whole strawberries, and you'll only be consuming 46 calories.
