A study has found if people adhered to the recommended 5 portions of fruit and vegetables each day and reduced their daily intake of salt to 3.5g as well as their saturated fat intake to 3% of their daily energy intake, this could prevent around 33,000 deaths each year. It was calculated that 20,800 coronoary artery disease deaths, 5,876 stroke deaths, amd 6,481 cancer deaths could be prevented each year by following such guidance. Around 12,500 deaths would be in the 75 years and under category.
