COLOMBO  - Sri Lanka on Sunday unveiled new guidelines encouraging devotees to donate low-sugar, healthier food to the country’s Buddhist monks after warnings that half of them risk developing diabetes. Sri Lanka’s monks eat food containing on average 12 teaspoons of sugar a day, but it should be reduced to a maximum of eight, while salt intake must also come down sharply, the health ministry said. Fifty per cent of the island’s 40,000 venerated monks face the risk of diabetes.
