You might soon be seeing warning signs along with your favourite chai, samosa and jalebi, at least on the walls near the places where you buy them. The central health institutions like AIIMS Nagpur have been instructed to install signs with "oil and sugar" health warnings in cafeterias, food courts and other public spaces, according to media outlets. The health ministry has ordered all central institutions, including AIIMS Nagpur, to install "oil and sugar boards" - vivid posters spelling out how much hidden fat and sugar lurk in everyday snacks. It's a first step toward treating junk food like tobacco.
