Around 60 per cent of snacks are too salty, according to a poll by the Consumer Council and the Centre for Food Safety. The watchdogs tested 80 salty snacks and found the highest amount of sodium in preserved fruits. Eating too much salt increased the risks of hypertension, one of the major causes of coronary heart disease and stroke, the council's Ron Hui Shu-yuen warned. According to the British Food Standards Agency, food with more than 600 milligrams of sodium or 1.5 grams of salt per 100 grams is on the high side of sodium content. It roughly equals a teaspoon of salt. One type of preserved sweet plum from the brand Aji Ichiban exceeded the British level by 20 times. Excluding the inedible seeds, there were 13 grams of salt per 100 grams of fruit. 'If you ate three pieces of the preserved plum, the volume of sodium you took in would amount to 20 per cent of the World Health Organisation's recommended daily intake level of 2,000mg of sodium,' Professor Hui said. Eating 18 plums would mean you had exceeded the recommended daily intake. Nam Yue Peanuts contained 2,200mg of sodium in its 200 gram packet. Consuming one packet a day would mean you had exceeded the recommended intake. Eating a bowl of imitation shark fin soup at CafE de Coral would mean you had consumed 90 per cent of the daily sodium intake. Salted plums, imitation shark fin soup and fish shaomai were three of the top snacks for salt content, according to a food habit survey of 5,000 people by the Centre for Food Safety. Consumers should check sodium content on food labels and choose brands with lower levels, recommended Anne Fung Yu-kei, the centre's principal medical officer. Aji Ichiban had withdrawn all preserved plum products since the Consumer Council informed the company of its findings, said company spokeswoman Pinky Chan Mei-lan. The company would try to make its plums less salty, but would not guarantee it would meet recommendations of the British agency. 'We need to consider whether the flavour of the plum is good or not,' she said. A CafE de Coral spokesman said the chain had authorised an external party to perform a quality test and found less salt in its imitation shark fin soup than had been found by the council test. That could be due to differences between samples, the spokesman said. Most adults consume an average of 3.5 to 4 grams of sodium daily, double the WHO's recommended limit, said registered dietitian Leslie Chan Kwok-pan. 'If people have eaten snacks on a day, then they should avoid processed foods such as sausages, canned pork and cup noodles,' he said. If children ate too much salt they could suffer from kidney diseases when they grew up, added the dietitian.
