Sorry, Pokey..

Juicing veggies concentrates their natural sugars and removes the beneficial fiber which makes it a lot more likely that you'll get an insulin response even from those 10 grams. I suppose you could drink the V8, but I can almost guarantee you that you will be a lot hungrier a lot sooner than if you have eaten 10 grams of carb worth of whole veggies instead and you'd soon find your body was missing the fiber that it needs to keep things running smoothly.
You don't have to eat just salad, you know. You can eat a lot of other veggies, cooked or raw, such as cucumber, celery, green peppers, broccoli and cauliflower. All of those are great with a nice creamy dip.
