From time to time, usually as I'm measuring foods to be tracked, I have wondered if I have been consistently cheating. Today I took the time to experiment to answer my own question, at least for this particular situation.
The question that I've pondered without answering for months - if not years - is whether the water/liquid in the can is included in the nutritional information. Today I took a can of low sodium pinto beans. I poured off the liquid which was about 1/4 cup. The label reported that the can contained 3.5 half-cup serving. So, you would expect it to hold 1 and 3/4 cups beans. When I measured the can, it held 2 full cups of water.
So, I'm thinking that when I measure out 1/2 cup of beans the nutritional info should be correct. I was concerned that if the liquid was to be counted and I always just selected the beans that I was repeatedly getting more calories and nutrients than I was tracking. Now I need to confirm this observation with several cans.
Yes, I know this experiment is bordering on the obsessive. Yes, I know that the answer for fruit in juice or syrup is different since the juice is actually higher in carbohydrates and calories than the fruit pieces. Yes, I know I don't have to be precise in order to succeed. Yes, I know all of those calorie listings are really estimates.
Nonetheless, I found it quite satisfying to find this particular answer today.
