Juice

Juice is high in carbohydrates and low in fiber, which can make it difficult to include in a low-carb diet even though it provides some important vitamins and minerals.

Fruit juice and smoothies are very high in carbohydrates and have a similar level of sugar as cola or lemonade, so really are best avoided. For instance, 42 grams of carbohydrates are included in 12 ounces (355 mL) of apple juice. This is even greater than the 39 grams in the same serving of soda. Grape juice, on the other hand, has an impressive 55 grams in the same serving size. Vegetable juice has fewer carbohydrates than fruit juice, but even so, a 12-ounce (355 mL) glass still provides 23 grams of carbohydrates, only 4 of which are from fiber. So, if you're on a low-carb diet, you might want to limit your juice intake.
