Fruit juice has come under the spotlight since medical experts recently started looking more closely at the link between high sugar intake and the risk for heart disease. And now, two medical researchers argue that because of its high sugar content, fruit juice could be just as bad for us as sugar-sweetened beverages like carbonated drinks and sodas.

In 2010, researchers said Americans' higher consumption of sugary drinks has led to more diabetes and heart disease over the past decade. Two years later, researchers reported that daily consumption of sugary drinks raised heart disease risk in men. 

Fruit juice Is Not A Low-Sugar Alternative To Sugar-Sweetened Drinks

There seems to be a clear misperception that fruit juices and smoothies are low-sugar alternatives to sugar-sweetened beverages.

Fruit juice has a similar energy density and sugar content to other sugary drinks, for example: 250 ml of apple juice typically contains 110 kcal and 26 g of sugar; and 250 ml of cola typically contains 105 kcal and 26.5 g of sugar.

Research is beginning to show that unlike solid fruit intake, for which high consumption appears linked either to reduced or neutral risk for diabetes, high fruit juice intake is linked to raised risk for diabetes.

One glass of fruit juice contains substantially more sugar than one piece of fruit; in addition, much of the goodness in fruit - fibre, for example - is not found in fruit juice, or is there in far smaller amounts. 

Also, although fruit juices contain vitamins and minerals that are mostly absent in sugar-sweetened drinks, the levels of nutrients in fruit juices many not be enough to offset the unhealthy effect that excessive consumption has on metabolism.
