Exploration of the Effect and Mechanism of Dietary Pattern Adjustment in Preventing Cardiovascular Diseases

Abstract

Cardiovascular disease, as the leading cause of death worldwide, poses a serious threat to human life and health. This study conducted a systematic review and analysis to explore in depth the effects and mechanisms of dietary pattern adjustment in preventing cardiovascular disease. Research has found that dietary patterns such as the Mediterranean diet, which are rich in vegetables, fruits, whole grains, and healthy fats, significantly reduce the risk of cardiovascular disease by optimizing nutrient intake, improving metabolic pathways, and reducing inflammatory responses. Specifically, the dietary fiber, vitamins, and minerals in these dietary patterns help control blood lipid and blood sugar levels, reduce oxidative stress and inflammatory reactions, and thus protect cardiovascular health. In addition, dietary pattern adjustments further reduce the risk of cardiovascular disease by improving metabolic disorders such as insulin resistance and reducing blood lipid abnormalities. In terms of practice, this study proposes effective methods such as dietary assessment, personalized adjustment, nutrition education and guidance, and demonstrates the positive effects of dietary pattern adjustment in preventing cardiovascular disease through practical cases. These findings not only enrich the theoretical basis for cardiovascular disease prevention, but also provide scientific dietary guidance for the public, which has important practical significance.
