Mediterranean-Style Diet Linked to Proteins Associated With Heart and Brain Health
Researchers explore possible biological pathways connecting healthy eating with ageing.
ScienceDaily reported on 24 October that USC researchers found higher levels of two small proteins in older adults who more closely followed a Mediterranean-style diet. The proteins may help explain some associations between this dietary pattern and healthy ageing.

A Mediterranean-style diet typically emphasises vegetables, fruits, legumes, whole grains, nuts, olive oil and fish, while limiting some sources of highly processed food. It has been widely studied for its association with cardiovascular health and other long-term outcomes. The USC research investigated whether this eating pattern was associated with levels of two small proteins that may be relevant to the health of the heart and brain. Identifying such biological markers could help researchers understand how diet is linked to changes in the body as people age. The findings do not prove that the proteins directly cause better health or that changing diet will necessarily raise their levels. Researchers need to determine whether these markers explain any of the observed health benefits and whether the associations persist in larger studies. For most adults, a varied eating pattern that includes adequate fibre, vegetables, fruit, whole grains and appropriate protein sources can support general health. Dietary choices should be adjusted for individual medical conditions, allergies, cultural preferences and nutritional requirements. This report is about a potential biological explanation, not a newly established treatment or a guarantee that a specific diet will prevent heart or neurological disease.
