Background: The proportion of elderly is increasing worldwide. This trend is paralleled by an increase in chronic diseases, such as cardiovascular disease. A limited number of studies have investigated the effect of diet on cardiometabolic risk factors (such as hypertension, hypercholesterolemia, diabetes, obesity) in older populations, despite the fact that diet plays a significant role in elderly health. In this review, a summary of studies that have evaluated the effect of dietary habits on cardiovascular disease risk in elderly populations is presented.
Methods: A search was made in available databases (PubMed and Scopus) looking for results from observational studies and clinical trials that assessed dietary habits on cardiovascular disease risk in elderly populations (>65 years old). Studies during the last decade were retrieved and summarized.
Results: All eight of the reviewed observational studies and all three reviewed clinical trials performed in elderly populations reported an inverse association between healthy dietary patterns with cardiovascular disease risk and its predisposing markers.
Conclusion: Dietary intervention strategies should be implemented in older adults, in order to prevent cardiovascular disease morbidity and mortality, and improve quality of life.
