Unlike sugary drinks, 100% fruit juices do have nutritional value. Many parents see them as a way to get their kids to eat fruit, but they are high in natural sugar. It's best to replace fruit juice with real fruit. Real fruit has fiber that is filling and missing from fruit juice. When serving 100% fruit juice: 1) Keep the portions small; 2) Take a look at the amount of sugar and calories they are getting; and 3) Instead of sugary drinks serve them water the rest of the day.
