Nutrition: Chronic Illnesses

United Kingdom dietary recommendations are based on advice from the Scientific Advisory Committee on Nutrition (SACN).

UK dietary advice, as depicted in the UK’s Eatwell Guide and based on the SACN’s advice, indicates that a healthy balanced diet is one based on fruit, vegetables, and higher fibre starchy foods. It is also recommended that high consumers of red and processed meat should reduce their consumption to less than 70 grams per day. Evidence indicates that a diet in line with the Eatwell Guide is associated with a reduced risk of non-communicable diseases such as heart disease, type 2 diabetes, and some cancers.

The SACN considered the topic of plant-based diets at its horizon scan meeting in 2022 and agreed that this was an important topic that would continue to grow in interest. The SACN added the topic to its watching brief. The SACN is considering it future work programme at its horizon scanning meeting on 18 June 2026.

Topics to be covered as part of the SACN’s future work programme that are relevant in relation to plant-based diets include protein, iron, iodine, and omega-3 fatty acids. These assessments are likely to consider the adequacy of animal verses plant sources. In addition, the SACN is currently supporting a Food Standards Scotland review of red and processed meat in relation to Food Standards Scotland’s dietary goals.
