2026 Dietary Guidance to Improve Cardiovascular Health: A Scientific Statement From the American Heart Association

Poor diet quality is strongly associated with elevated cardiovascular disease morbidity and mortality risk. This American Heart Association scientific statement for food-based cardiovascular health optimization and cardiovascular disease risk reduction guidance summarizes available evidence and provides contextual guidance for the key features of heart-healthy dietary patterns. It enumerates collateral benefits of adopting a heart-healthy dietary […]

Nut consumption and risk of cardiovascular disease events and all-cause mortality: A systematic review and dose-response meta-analysis of prospective cohort studies

Background: Evidence for the effects of nut consumption on cardiovascular disease (CVD) events and all-cause mortality has been reported inconsistently. Aims: To assess the associations between nut consumption and CVD events and all-cause mortality. Methods: We searched the Web of Science, Embase and PubMed up until 24 October 2023. In order to compute relative risks […]

Daily Almond Supplementation Improves Blood Pressure and Lipid Profile in Pregnant Women with Hypertension and Dyslipidemia: A Randomized Controlled Trial

Background: Hypertension and dyslipidemia during pregnancy increase the risk of adverse maternal and fetal outcomes. While almond supplementation is recognized for its cardioprotective effects in non-pregnant populations, its role during pregnancy remains underexplored despite its potential as a safe and accessible dietary intervention. Objective: To evaluate the effects of almond supplementation at two doses (10g/day […]

Nut Consumption and Risk of Cardiovascular Disease and Ischemic Heart Disease Mortality: The Adventist Health Study 2

Background: Cardiovascular disease (CVD) and ischemic heart disease (IHD) are leading causes of mortality worldwide. Nut consumption has been associated with reduced risk. Objectives: To examine the associations between total nut and tree nut intake with CVD and IHD mortality, and to explore the potential benefits of substituting nuts for less heart-healthy foods. Methods: This […]

Effect of the Mediterranean diet supplemented with olive oil versus the Mediterranean diet supplemented with mixed nuts on blood pressure and serum lipid indexes among adults: a systematic review and meta-analysis of randomized controlled trials

Background and Aim: Hypertension and dyslipidemia are major risk factors for cardiovascular disease (CVD). This systematic review and meta-analysis compared the effects of two Mediterranean (MED) dietary patterns—one supplemented with olive oil and the other with mixed nuts—on blood pressure and lipid profile. Methods and Results: Relevant studies published until April 24, 2024, were thoroughly […]

Association Between Nut Consumption and Metabolic Syndrome in Korean Adults

Objective: Although nuts have been reported to lower the risk of multiple diseases, evidence regarding their effect on metabolic syndrome (MetS) in Asian populations is limited. Therefore, this study aimed to clarify the association between nut consumption and the risk of MetS. Methods: A cross-sectional analysis was conducted using data from the seventh Korea National […]

Impact of a 12-Week Hypocaloric Weight Loss Diet with Mixed Tree Nuts vs. Pretzels on Trimethylamine-N-Oxide (TMAO) Levels in Overweight Adults

Trimethylamine N-oxide (TMAO), a gut microbiome metabolite linked to cardiovascular health, can be influenced by dietary factors like choline intake and diet quality. This study compared the effects of mixed tree nuts (MTNs) and pretzels, as part of a 12-week hypocaloric weight loss diet, on TMAO levels and identified dietary predictors. Methods: Plasma samples from […]

Pecan Consumption Improves Cardiometabolic Risk Factors in Overweight and Obese Adults

Objectives: Tree nut intake benefits cardiometabolic health, but polyphenol-rich pecans have been less studied. The aim of this dissertation was to evaluate the cardiometabolic effects of consuming pecans in place of usual snacks compared to usual intake in adults at risk for cardiometabolic diseases. Methods: This was a 12-week parallel randomized controlled trial in which […]

Does Medication Status Impact the Effectiveness of Nuts in Altering Blood Pressure and Lipids? A Systematic Review and Meta-Analysis

Context: Nut consumption is attributed to improvements in risk factors for cardiovascular disease (CVD), including high blood pressure (BP) and dyslipidemia. However, it is unclear whether these effects are altered with concurrent treatment with BP and lipid-lowering medication. Objective: We sought to investigate the effects of the consumption of whole tree nuts and peanuts (collectively […]
