The fruit juice industry has essentially taken the 'apple-a-day' mentality and used it to sell fruit juices as healthy," said Barry Popkin, a professor in the department of nutrition at the University of North Carolina at Chapel Hill's Gillings School of Public Health.
Popkin and other experts would rather see people eating whole fruit. Because most juicing methods remove the produce's fiber, drinking juice omits one of the key benefits of eating fruit, while delivering huge amounts of sugar and calories.
"Every one of the long-term studies of the health effects of fruit juices shows that you increase your risk of diabetes and weight gain" with regular juice consumption, Popkin said.
One 2010 study in the American Journal of Epidemiology followed more than 43,000 adults in Singapore for five years and found that those who consumed two or more servings of fruit juice per week had a 29 percent higher risk of developing diabetes than those who didn't drink juice regularly — not far behind the 42 percent increased risk for weekly soda drinkers.
