In an analysis of the UK Government’s dietary guidelines that were updated in March 2016, the team also found that sticking to this advice may also prevent as many as 850,000 diabetic cases over the next ten years,
This, the study’s authors said, could be achieved by reducing of foods high in sugar and fat by half (53%), reducing consumption of beans, pulses, fish, eggs, meat and other proteins by a quarter (24%) and cutting dairy and alternative products by a third (29%).
At the other end of the scale, a substantial increase (69%) in consumption of potatoes, bread, rice, pasta and other starchy carbohydrates and fruit and vegetables (71%), was also required.
The findings follow a review of the latest evidence on carbohydrates and health by the Food Standard Agency's (FSA) Scientific Advisory Committee on Nutrition (SACN).
Here, the advisory panel to the UK Government advised the reduction of the recommended average intakes of free sugars to no more than 5% of dietary energy intake.
Free sugars include sugars added to foods and beverages before consumption, and naturally occurring sugars such as those in honey, syrups and fruit juices.
The Eatwell Guide does not include sugars incorporated within intact fruits and vegetables or sugars naturally present in milk.
“The strengthening of sugar and fibre recommendations more than doubles the health that could potentially be gained if everyone were to follow dietary recommendations without increasing energy intake,” the study stated.
“The results show how big changes in fruit and vegetables and meat consumption that are recommended in the Eatwell Guide could translate into big improvements in health when compared to average consumption levels in the current UK diet.”
Meat and dairy industry
While the analysis also outlined the health gains from reducing meat and dairy consumption, they also highlighted the implications such a drastic reduction would have on the two industries.
“There would be economic implications for the meat and dairy industries due to reduced demand for their products,” said the team. “While agriculture adds just 0.7% to GDP in the UK, meat and dairy commodities are responsible for two-thirds of that value.”
Despite this prediction, previous findings have argued that the impact on total food and drink costs for the individual would on average be insignificant, actually reducing slightly from, on average £6.02 (€6.93) to £5.99 (€6.90) in 2016.
In addition to an extension to the life span, the model suggested that through prevention of type 2 diabetes, cardiovascular diseases and colorectal cancer may also possible.
A smaller, but still substantial, number of cases of stomach, lung and breast cancer would also be prevented.
The pattern of disease outcomes is similar with a diet that meets old recommendations, but substantially fewer cases of disease would be averted, ranging from 38% fewer cases of diabetes up to 79% fewer cases of stroke.
