Maybe a reason for the difference, is when you cook green beans they soften and you can get a WHOLE LOT MORE in a cup measure! At least that is what I find with cooked beans, carrots, etc. Softer food measures differently. So your best bet if you are using fresh food is scroll down that list of food and find how your food is prepared among the listing... such as, Green Beans, cooked, from Frozen, boiled, drained without salt. I happen to like the varied listings, especially when I am eating food that someone else has prepared. I can get a view of how the rest of the world eats... and how to accurately log that food.
1 pound to goal...
Don't worry I am setting new goal once I get this little pound off!
