"Forcing food manufacturers to cut salt levels in processed food could help cut heart disease rates, claim Australian researchers. A theoretical study suggests mandatory salt limits could help reduce heart disease rates by 18% -- far more than by using existing voluntary measures. High-salt diets are linked to high blood pressure, which can lead to heart attacks or strokes. Adults are advised to consume a maximum of 6g of salt a day -- about a teaspoon. The study looked at the effectiveness of different strategies around the world for reducing salt in processed foods. Many countries, including Finland, the US, the UK, Canada, France, Australia and New Zealand, have adopted salt reduction programmes based on food labelling and voluntary cuts. Australia uses a 'Tick' programme, where food manufacturers can use a health promotion logo on packaging if they volunteer to cut salt content."
