Which has more carbohydrates—raw tomatoes or cooked tomatoes?

The carbohydrate contents of both raw and cooked tomatoes is very similar. However, cooking softens the fiber and may make the cooked tomatoes more easily digested and absorbed. A higher rate of digestion and absorption would more rapidly increase blood glucose (sugar). Keep in mind, too, that tomatoes are an excellent source of vitamins and fiber.

Just be sure to carefully read the nutrition labels on canned or processed tomato products. Stewed tomatoes typically contain added sugar, making this product higher in total carbohydrate than plain canned tomatoes.
