Some vegetable juices can be a bit grassy for some, especially green juices, but when mixed correctly they are absolutely refreshing.
If juicing a lot vegetable juices are by far the preferred choice, as fruit juices are quite high in sugar. You may also have heard that fruit juices should be limited to one per day, whereas vegetable juices can be enjoyed throughout the day.
Green apples work great as a sweeter and can be added to almost any vegetable juice. Another great thing to add is ginger, which works great with both fruits and veggies.
