Smoothies and fruit juice are the new danger, said Popkin, a distinguished professor at the department of nutrition at the University of North Carolina, in an interview with the Guardian.
He added: It's kind of the next step in the evolution of the battle. And it's a really big part of it because in every country they've been replacing soft drinks with fruit juice and smoothies as the new healthy beverage. So you will find that Coke and Pepsi have bought dozens [of fruit juice companies] around the globe.
In the UK, Coca-Cola owns Innocent smoothies while PepsiCo has Tropicana. Launching Tropicana smoothies in 2008, Pepsi's sales pitch was that the drink would help the nation to reach its five a day fruit and vegetable target. "Smoothies are one of the easiest ways to boost daily fruit intake as each 250ml portion contains the equivalent of 2 fruit portions," it said at the time.
However, Popkin says the five a day advice needs to change. Drink vegetable juice, he says, but not fruit juice. "Think of eating one orange or two and getting filled," he said. "Now think of drinking a smoothie with six oranges and two hours later it does not affect how much you eat. The entire literature shows that we feel full from drinking beverages like smoothies but it does not affect our overall food intake, whereas eating an orange does. So pulped-up smoothies do nothing good for us but do give us the same amount of sugar as four to six oranges or a large coke. It is deceiving. Smoothies and fruit juices are a new risk to health US scientists warn
