We need to eat our fruit, not drink it. This is especially important for our children. While we like to think that fruit juice is a convenient way to get all the health benefits that fresh whole fruit provides, fruit juice delivers high levels of sugar and high levels of enamel-damaging acid. Whole fruit offers fiber and other nutrients that juice does not. Fruit juice can lead to cavities, weight gain, as well as unhealthy weight loss. Juice also can cause diarrhea when toddlers drink too much of it.
Fruit juice is popular among children of all ages. The convenience factor of single-serve juice boxes and small bottles combined with children's eagerness to drink juice make it a popular choice for parents on the go. However, parents should consider skipping it and look at the benefits of whole fruit instead. Water is your best option to rehydrate active children. Children should avoid sports drinks as these usually contain high acid levels and are unnecessary for children in most cases.
