Improving diets and multimorbidity prevention.

Area of Science:

• Public Health Nutrition
• Health Policy
• Non-Communicable Disease Prevention

Background:

• The UK's Major Conditions Strategy targets cancers, diabetes, dementia, mental ill health, musculoskeletal disorders, cardiovascular disease (CVD), and chronic respiratory diseases.
• These conditions cause 60% of disability-adjusted life years lost in England, with 25% of adults experiencing multimorbidity.
• Nutrition and excess weight significantly impact the onset, prognosis, and quality of life for individuals with these major conditions.

Purpose of the Study:

• To review key dietary risks associated with the UK's Major Conditions Strategy focus areas.
• To examine population-level policies aimed at improving diets and mitigating health risks.
• To explore the role of nutritional science in informing health improvement policies and disease management.

Main Methods:

• Analysis of UK government documents, including the Major Conditions Strategy and the Eatwell Guide.
• Review of scientific evidence linking diet to major non-communicable diseases.
• Examination of dietary data from the National Diet and Nutrition Survey and Kantar consumer data.
• Assessment of policies such as food labelling, public procurement, sugar/salt reduction, and reformulation.

Main Results:

• Most individuals in the UK do not meet national dietary recommendations, as indicated by consumption and purchase data.
• A range of policies, from encouraging healthier choices (labelling, procurement) to minimizing unhealthy ones (sugar/salt reduction, reformulation), are considered.
• Nutritional strategies can play a role in managing established non-communicable diseases.

Conclusions:

• Significant potential exists for improving population health through even modest dietary enhancements.
• Evidence-based dietary policies are essential for addressing the burden of major conditions.
• Integrating nutritional science into health policy can lead to substantial public health gains.
