Most prepared grocery items list calories by serving size. The serving size of prepared reconstituted lemon juice could be so small as to be almost calorie-free :-) For example, a lemon wedge only has one calorie, a tablespoon only 3. An average whole lemon only has around 17 calories! btw, it is not necessarily the sugar content that determines calories but the amount of carbs.......there is very little sugar in a lemon but a fair amount of carbohydrates.

Reconstituted lemon products (i.e. 'RealLemon' juice) are not the same as a squeezing a fresh lemon. There is a lot of water and what is called 'lemon oil' extracted from the leaves as well as preservatives. If you want real lemon juice, use a real lemon!!

I find it entertaining that the label on lemon juice says "contains artificial ingredients", while the label on dish soap says "contains real lemon juice"... I'm sure what you are looking at is chemistry set lemon juice like most of the products that are sold to us as "real".

Heck, "100% pure fresh squeezed orange juice" gets pasteurized, stored in tanks for months, then gets re-assembled with "flavor packs" because the pasteurization process kills the flavor. Because the ingredients in the flavor packs were derived from oranges, they can call it "real".

Welcome to America, "Reality" TV = fake crap, "Real" food products = fake crap.

redbeard, you need to let us know the name/brand of the product of which you are speaking. How can we answer your question otherwise?
