Drinking coffee may be linked to lower mortality risk in type 2 diabetes patients.
In this study, the researchers conducted an exhaustive literature search through PubMed, Scopus, and Web of Sciences up to November 2020. They were looking for prospective cohort studies that evaluated the link between coffee consumption and the risk of cardiovascular disease and mortality in patients with type 2 diabetes. Two reviewers took on the work of extracting relevant data and assessing the certainty of evidence using the GRADE approach. A random-effects model was deployed to estimate hazard ratios. Dose-response connections were modeled using a one-stage mixed-effects meta-analysis. The researchers included ten prospective cohort studies that totalled 82,270 cases.
The results showed an interesting trend: compared to those who did not consume coffee, the hazard ratios were consistently lower for mortality outcomes and cardiovascular disease, especially where the consumption rate was four cups per day. Importantly, no such association was found for either cancer mortality or stroke. The evidence suggested a potential inverse monotonic association between coffee drinking and mortality across all causes and cardiovascular disease, alongside a linear association for coronary heart disease and total cardiovascular events. The degree of certainty in these results was moderate for all-cause mortality, but was low or very low for all other reported outcomes.

Sardines, being an affordable source of Omega-3 and other cardioprotective nutrients, can potentially reduce the need for Omega-3 supplementation and manage cardiometabolic diseases.
2023 Frontiers in Nutrition Eating more sardines instead of fish oil supplementation: Beyond omega-3 polyunsaturated fatty acids, a matrix of nutrients with cardiovascular benefits Santos HO, May TL, Bueno AA
Review Article Cardiovascular Disease Cholesterol High Blood Pressure
The abstract primarily acknowledges the importance of Omega-3 polyunsaturated fatty acids with respect to managing diseases related to heart health and metabolism, for instance, type 2 diabetes, hypertension, hypertriglyceridaemia, and fatty liver disease. However, these fatty acids are not the sole beneficial component of sardines. Minerals including but not limited to calcium, potassium, and magnesium as well as substances like taurine and arginine found in sardines have a significant role in controlling mild inflammation and oxidative stress which are usually present in cardiovascular diseases and hemodynamic dysfunction.
The results discussed in the abstract suggest a positive correlation between consumption of sardines and potential cardiometabolic benefits. By considering the dose-response relationship effects, a pragmatic approach towards consumption of nutrients was suggested. The intake of sardines was seen not only as a means of Omega-3 supplementation but also as a comprehensive approach to enhancing cardiovascular health. The abstract concludes with an emphasis on the many beneficial nutrients found in sardines besides Omega-3, underlining the need to shift the focus from synthetic supplementation to natural dietary improvement.
Almond consumption has beneficial impacts on cardiovascular diseases, diabetes, obesity, and it can improve cognitive performance and protect against skin aging.

Review Article Almond Cardiovascular Disease Cognitive Function
The methodology employed in this study included analyzing a range of clinical studies centered on the health benefits linked to the consumption of sweet almond nuts. Various health outcomes correlated with almond consumption were investigated such as body weight, food intake, blood pressure, blood lipid composition, glucose and insulin levels, oxidative status, liver enzymes, and some inflammation biomarkers.
The discussion of the results reveals that almond consumption has been found to create favorable alteration in aspects like body weight, food intake, blood pressure, blood lipid composition, glucose, and insulin levels, as well as oxidative status, liver enzymes, and inflammation biomarkers. These findings highlight the beneficial impact of almonds on multiple health issues including cardiovascular diseases, diabetes, and obesity. Additionally, the consumption of almonds has been associated with improved cognitive performance and protection against skin photodamage and aging.
Heavy coffee consumption increases the risk of cardiovascular disease mortality in individuals with severe hypertension, while green tea consumption does not.

Cohort Study Cardiovascular Disease Coffee Green Tea
With the use of the Japan Collaborative Cohort Study, researchers assessed 18,609 participants, both male and female, aged between 40 to 79 years. These participants had varying blood pressure levels, categorized into optimal and normal BP, high-normal BP, and two stages of hypertension. They completed a questionnaire about their lifestyle, diet, and medical history, and underwent health examinations, which were followed up until 2009. The association of coffee and green tea consumption on cardiovascular disease mortality was then calculated using a Cox proportional hazard model.
It was found over an 18.9 year follow-up period that heavy coffee consumption was linked to increased risk of cardiovascular disease mortality among those suffering from the second to third grade of hypertension. In stark contrast, people with optimal and normal, high-normal blood pressure and first grade hypertension did not show such associations between coffee consumption and cardiovascular disease mortality. Interestingly, the risk of cardiovascular disease mortality was not found to be increased across any blood pressure categories in relation to green tea consumption.
Consumption of tea and coffee may possibly provide anti-inflammatory effects, contributing to reduced cardiovascular risk and mortality.
2023 Pharmacological Research Coffee or tea: Anti-inflammatory properties in the context of atherosclerotic cardiovascular disease prevention Surma S, Sahebkar A, Banach M
Review Article Anti-Inflammatory Cardiovascular Disease Coffee
The methodology of this narrative review examined the potential anti-inflammatory properties of consuming tea and coffee as a factor in reducing the risk of cardiovascular disease. This was done by analyzing a plethora of studies and meta-analyses that explored the impact of diet on inflammation, with a keen focus on the consumption of these beverages. The studies looked at a variety of risk factors for atherosclerotic cardiovascular disease, including inflammation biomarkers such as C-reactive protein, along with the impact of modern lipid-lowering treatments.
In discussing the results, it was noticed that inconsistent findings were produced from the analysed studies which made a conclusive determination challenging. However, a trend was observed where drinking tea and coffee seemed to raise adiponectin levels, reduce reactive oxygen species and lower low-density lipoprotein cholesterol levels. Despite these potential anti-inflammatory properties of tea and coffee being somewhat uncertain due to various confounding factors, their consumption is still recommended as part of a healthy diet.

Systematic Review Blood Sugar Cardiovascular Disease Heart Disease
Tart cherry juice was found to lower fasting blood sugar but didn't have a significant impact on blood pressure, insulin, cholesterol, body fat, or weight. It is rich in antioxidants, which may be why it's beneficial for the heart. Changes in gut bacteria might also play a role. More research with larger and varied groups of people is needed to confirm these findings and understand them better. In the meantime, healthcare professionals may consider suggesting tart cherry juice for heart health.
