To determine which fruit among apples, cherries, oranges, and watermelons would raise the level of sugar in blood by the least amount, we need to compare the carbohydrate content of these fruits. Here's the carbohydrate content for each:
- Apples: 17 grams of carbohydrates
- Cherries: 19 grams of carbohydrates
- Oranges: 21 grams of carbohydrates
- Watermelons: 12 grams of carbohydrates
From these values, we can see that the fruit with the smallest amount of carbohydrates is watermelons, with only 12 grams of carbohydrates per serving.
Thus, a serving of watermelons would raise the level of sugar in blood by the least amount compared to apples, cherries, and oranges.
