Normally, juices pack less nutrient power than whole fruits. And virtually all of a fruit's fiber is lost if you use a juice extractor. This way, juice offers more nutrition than does eating the whole fruit. Buy juices that are labeled 100 percent juice.
Fruit juice is more apt to quickly raise blood glucose and insulin levels than is whole fruit.
Buying Tips Fresh is best. Frozen fruits are a good stand-in for fresh. Canned fruits are lower in vitamins, nutrients and antioxidants. Buy fruits packed in water or unsweetened juices. Syrups add sugar and calories.
