I know in the US, food companies have to put nutrition facts on their packaging.  But isn't it suppose to be reasonably close to accurate?  I'm calling out Bumble Bee.  I've got a pouch of their Premium light tuna in water.  The Nutrition Facts say a serving size is 2 oz (56 g ~ about 1/4 c).  That is followed by Servings Per Pouch about 2.  That implies that if one eats the whole pouch, one should double the nutritional information provided.

However, I hadn't paid attention before to the front of the pouch before.  When I looked at it today, I saw that the Net WT is 5 oz (142 g).  What does the other ounce consist of?  I tried squeezing out any water, but only got a few drops, nothing that would come near an oz.  That added ounce isn't "about" 2 servings, it is pretty close to a half serving. 

I know I have to pay attention to the number of servings and serving size, but didn't realize I also need to pay attention to the size of the entire package.  When they don't match, how does one account for the added weight or volumn when tracking calories? 

Checked one other tuna pouch I have handy from a different company.  The moisture content is similar looking and they were able to get it right.  Like the product but am disappointed in Bumble Bee's inconsistency between the front and back of the pouch. 

While the additional 30 calories isn't a huge make or break it number, it does make me cranky adding it to my daily calories consumed.  And it also makes me wonder what other packages aren't consistent/don't have the info quite right.
