Vegetable juice: As good as whole vegetables?
Is vegetable juice as good as whole vegetables for meeting the number of recommended servings a day?
from Katherine Zeratsky, R.D., L.D.
Vegetable juice can be an easy way to increase the amount of vegetables in your diet, but you shouldn't routinely use it to replace whole vegetables.
Most adults should get at least three to four servings of vegetables a day, depending on their age, sex and level of physical activity. Any type of vegetable counts, whether it's raw, cooked, fresh, frozen or canned. Vegetable juice counts, too. Just make sure it's 100 percent vegetable juice and low in sodium.
While vegetable juice has plenty of vitamins and minerals, it's lower in fiber and less filling than is a serving of most whole vegetables. Enough fiber in your diet may reduce your risk of constipation, high cholesterol, high blood sugar and weight gain.Next question
