Here is a question I recently received from FOODPICKER.org:
I have heard I should avoid fruit juice since I have diabetes. What about vegetable juices? Can I have tomato juice and other vegetable juices?
Answer: While vegetable juice will contain less carbohydrate than fruit juice, it lacks fiber (like fruit juice) when compared to whole vegetables or whole fruits.
Tomato juice and other vegetables juices that are canned or store bought are often high in sodium as well. One-half cup of vegetable juice or tomato juice contains 5 grams of carbohydrate.
You can certainly include this in your diet. You will just want to watch portion sizes if you have it often. Also, consider having whole vegetables in your diet so you can reap the benefits of fiber.
