Prescription for a better British diet

Area of Science:

• Nutritional Science
• Public Health Nutrition
• Dietary Planning

Background:

• Current dietary guidelines in Britain require reassessment.
• Existing food supply data in the UK provides a basis for dietary recommendations.

Purpose of the Study:

• To devise a new method for establishing upper or prescriptive levels of recommended nutrient intakes.
• To propose actionable dietary changes for the British population.

Main Methods:

• Analysis of current UK food supplies.
• Development of a model for nutrient intake assessment based on food groups and nutrient concentrations per energy unit.
• Proposal of specific food intake modifications for the national diet.

Main Results:

• Recommended moderate reductions in fat, sugar, meat, and alcohol intake.
• Advocated for increased consumption of cereals, potatoes, vegetables, and fruit.
• Maintained current intake levels for milk, eggs, fish, pulses, and nuts.
• Projected an increase in the proportion of food energy from protein despite reduced meat consumption.

Conclusions:

• The proposed dietary changes are substantial yet feasible, with minimal disruption to agricultural and trade policies over ten years.
• The developed methods are flexible for individual and group diet planning, prescription, and evaluation of dietary surveys.
• This approach offers a practical framework for improving the national diet and associated health outcomes.
