A study has stated that about 4000 lives can be saved in Wales, Scotland and Northern Ireland every year if an English styled diet is consumed.
According to experts from Oxford University, more fruits and vegetables are consumed by people in England and their food contains less of salt and fat content and this leads to lesser heart problems and even certain cancers.
They added that the diet divide could be closed by a tax on fatty and salty foods and subsidies on fruit and vegetables.
According to the British Heart Foundation, authorities have to address inequalities in the nations.
Official figures also state that when it comes to death rates for heart disease and cancer, in Scotland, Wales and Northern Ireland it is more when compared to England.
It was concluded based on last year's data that if a diet containing vegetables, fruits, less fat and salt was consumed then about 30,000 lives would have been saved in the UK alone.
Differences that exist within the UK are something that experts from the Department of Public Health at the University of Oxford have now turned to.
They tried to establish a link between the English diet and avoiding deaths from heart disease, stroke and 10 cancers linked with poor diet in Scotland, Wales and Northern Ireland.
They added that perfect diet is not followed in England either but other UK counties should achieve the English diet.
