Hi, thanks for any help you can offer.
To clarify my question with a specific example: I am trying to measure green beans. The nutrition information for this product is the link below.
http://fatsecret.com/calories-nutrition/safeway/french-style-green-beans
The green beans come in a can that says it has 3.5 servings total. However, I know that these 3.5 servings are a result of the liquid in the can as well. If I drain the water in the can and weigh the beans, I find about 200 or so grams instead of the expected 3.5*120 = 420 grams.
So my question is this, how many calories of green beans are actually in the can? If I eat the entire can without measurement, then the caloric content would be 3.5*20 = 70 total calories. If I drain the liquid then measure the beans (200 grams), The calories would be (200/120)=1.66*20=33.33 calories… if indeed the nutrition facts are for the beans without liquid.
Essentially, I don’t understand if the liquid in the can means anything when it comes to measurement. If not negligible, a serving of green beans would have to have some percentage of the vegetable and some percentage of the water to match the amount listed.
I hope that this question makes sense, and I would really, really appreciate any help that can be offered!! Thanks so much!
With Jim’s answer in mind… So then, tell me if this is an acceptable strategy for a potentially unlisted vegetable: I drain the liquid and weigh the remaining vegetables (let’s say the weight is 200 grams)
If the can indicates that there are 3.5 servings total (with 1 serving being 20 calories) and I want 20 calories of this vegetable, then I measure out [1/3.5=28.6% of 200] = 57.1g of the vegetable to obtain these 20 calories.
Thoughts?
No, you’re meant to drain the liquid, which usually contains a lot of salt.
Short and to the point answer: No.
References :
don’t include the liquid I think it is there to preserve the vegetables and only include the liquid if a recipe says so. Buy a packet of dry beans either from a health food store, asian store, or in a supermarket health food section. The liquid that is in a can of beans is packed with salt so be weary of that.

No, you throw the liquid away and just measure the weight of beans themselves. The liquid has no real nutritional value.
Consult the USDA nutrition database:

Here you go for canned green beans solids, drained liquid:

Note that the ENERGY is 98 calories per 100 grams
Therefore, each gram equals 98/100 = 0.98 Calories
200 grams therefore equals 200 x 0.98 = 196 calories
