Juicing is good, but its quite a bit of sugar you're consuming and you lose the fiber. Yes, it maybe easier to assimilate the nutrients but you don't need that much sugar.
How about trying to make a smoothie instead. You get the nutrients and fiber, which is great as many pregnant women can be constipated. Hard things like beets, juice and add to the smoothie. As long as the blender is strong enough, apples, beets, could be placed in as well.
Oh, for my smoothies its some frozen fruit and I toss in a serving of salad and protein powder. It's great for those that can't keep down foods, smoothies do the trick for many.
