Should You Drink Green Juice

TIME  online


“Veggie juice is very healthy,” says Barry Popkin, PhD, professor of nutrition at the University of North Carolina at Chapel Hill School of Public Health. And way healthier, he says, than fruity concoctions like smoothies, which Popkin recently came down against in this very series. The main concern about juicing and blending—that pulverizing produce lets sugar rush into your bloodstream faster without fiber—isn’t a big issue with juice made from vegetables. “It is low in sugar, so quite different,” Popkin says...

Death by chocolate: the sugar-fueled diabetes surge in South Asia

The Guardian  online


Barry Popkin, a nutrition and population expert at the University of North Carolina, has suggested that after economies improve and famine recedes, patterns of food consumption and physical activity shift in ways that promote the emergence of obesity and its cardiovascular and diabetes complications. Perhaps just as significantly, Indian memories of famines real or threatened during the past century may persist in ways that promote the buffet dining model. Unconscious fear of deprivation prompts the second helping...

Salon  online

Of the trend, Popkin asked, ”Is that because people think it’s quote-unquote natural?”...

China: nutrition guiding light or ticking time bomb?

The Guardian  online

One of the authorities on China’s obesity rates, Barry Popkin, estimates that obesity lowered China’s Gross National Product (GNP) by 3.6% in 2000 and, given projections of income, urbanisation and diet globalisation, that it will grow and in doing so, will lower GNP by 8.8% in 2025...
