Is V8 Paleo?

Yes

A big part of living a Paleo lifestyle is to generally avoid eating or drinking anything that comes out of a can. More often than not, they tend to come loaded with added sugars and preservatives that don’t resemble food, but there’s more to the story. If canned foods and drinks include all-natural ingredients (that are truly all natural, not just claiming to be) there’s no reason they can’t be included on the Paleo menu.

Sodium/Potassium Balance

V8 is one such rare packaged drink. It’s basically just tomato juice and salt. The salt does pose a slight problem because there’s enough in there to counteract all the potassium contained in the tomato juice. There’s nothing inherently bad about salt, but one of the main reasons we should be eating lots of vegetables is to balance out the sodium we get elsewhere in our diet. If you consume lots of salt with your vegetables, that kind of defeats the purpose.

The Importance of Variety

Another important aspect to living a Paleo lifestyle is to eat a wide variety of foods because that’s the best way to make sure we get as many different nutrients as possible. While V8 claims to have all your vegetables covered, it’s almost entirely tomatoes, which technically aren’t even vegetables. One of the best ways to get and stay healthy is by eating a wide variety of foods, including spinach, onions, broccoli, and cauliflower and V8 doesn’t help you with any of those.

Mark Sisson gave V8 his seal of approval, with some notes for concern.
