CARACAS, Venezuela – One of every three people in Venezuela is struggling to put enough food on the table to meet minimum nutrition requirements as the nation’s severe economic contraction and political upheaval persists, according to a study published Sunday by the U.N. World Food Program. A nationwide survey based on data from 8,375 questionnaires reveals a startling picture of the large number of Venezuelans surviving off a diet consisting largely of tubers and beans as hyperinflation renders many salaries worthless. A total of 9.3 million people – about one-third of the population – are moderately or severely food insecure, said the World Food Program’s study, which was conducted at the invitation of the Venezuelan government.
