Food labels and nutrition facts: What do they really mean?
Nutrition Facts panel: Serving size = 1 cup, Servings per container = 2
Although you may heat and eat an entire can of soup, check the number of servings per can, which is often two. The nutrition information is based on one serving, which is 1 cup. So, if you eat the entire can (about 2 cups), double all of the nutrition numbers you see on the label. Amounts that sound reasonable for one serving may be excessive if you actually eat two servings.
