Food Insecurity and Its Cardiovascular Implications in Underresourced Communities.

Background: Food insecurity is linked to poorer cardiovascular health (CVH) outcomes, particularly in underresourced communities, where social determinants of health play a critical role. Despite the recognized connections, there remains a lack of empirical evidence delineating the implications of food insecurity on CVH. CVH, a broader concept than cardiovascular disease, encompasses the overall well-being of the cardiovascular system and is supported by favorable lifestyle choices and physiological metrics.

Telomere length as biomarker of nutritional therapy for prevention of type 2 diabetes mellitus development in patients with coronary heart disease: CORDIOPREV randomised controlled trial.

Background: Telomere Length (TL), a marker of cellular aging, holds promise as a biomarker to elucidate the molecular mechanism of diabetes. This study aimed to investigate whether shorter telomeres are associated with a higher risk of type 2 diabetes mellitus (T2DM) incidence in patients with coronary heart disease; and to determine whether the most suitable dietary patterns, particularly a Mediterranean diet or a low-fat diet, can mitigate the development of diabetes in these patients after a follow-up period of five years.

Methods: The CORonary Diet Intervention with Olive oil and cardiovascular PREVention study (CORDIOPREV study) was a single-centre, randomised clinical trial done at the Reina Sofia University Hospital in Córdoba, Spain.
