Fish consumption and the 30-year risk of fatal myocardial infarction. Daviglus ML, Stamler J, Orencia AJ, Dyer AR, Liu K, Greenland P, Walsh MK, Morris D, Shekelle RB. N Engl J Med. 1997 Apr 10;336(15):1046-53. PMID: 9091800 Conclusions These data show an inverse association between fish consumption and death from coronary heart disease, especially nonsudden death from myocardial infarction.

"MedWire News: Zinc supplements could increase the risk for coronary heart disease (CHD) in healthy people by decreasing high-density lipoprotein (HDL) cholesterol levels, researchers claim. Initial findings from a meta-analysis in 14,238 participants from 20 trials suggested no impact of zinc supplements on plasma lipoprotein levels. But a secondary analysis in healthy individuals showed that zinc was associated with a significant decrease in plasma HDL concentrations. Furthermore, zinc was linked with a significant decrease in HDL cholesterol levels among participants with Type 2 diabetes or those undergoing hemodialysis. The researchers suggest the result in patients with diabetes may relate to the action of zinc in determining insulin levels. The meta-analysis included 33 interventions investigating the impact of zinc on lipid levels. The mean dose of elemental zinc used was 58 mg per day, which the researchers note is beyond the recommended upper level of intake of 40 mg."

Calcium:magnesium ratio in local groundwater and incidence of acute myocardial infarction among males in rural Finland. Kousa A, Havulinna AS, Moltchanova E, Taskinen O, Nikkarinen M, Eriksson J, Karvonen M. Environ Health Perspect. 2006 May;114(5):730-4. doi:10.1289/ehp.8438 PMID: 16675428 Results of this study with specific Bayesian statistical analysis support earlier findings of a protective role of Mg and low Ca:Mg ratio against coronary heart disease but do not support the earlier hypothesis of a protective role of Ca

Single food focus dietary guidance: lessons learned from an economic analysis of egg consumption. Schmier JK, Barraj LM, Tran NL. Cost Eff Resour Alloc. 2009 Apr 14;7:7. PMID: 19366457 Methods A risk apportionment model estimated the increased risk for coronary heart disease (CHD) attributable to egg cholesterol content, the decreased risk for other conditions (age-related macular degeneration (AMD), cataract, neural tube defects, and sarcopenia) associated with egg consumption, and a literature search identified the cost of illness of each condition. The base 795 case scenario calculated the costs or savings of each condition attributable to egg cholesterol or nutrient content. Results Given the costs associated with CHD and the benefits associated with the other conditions, the most likely scenario associated with eating an egg a day is savings of $2.82 billion annually with uncertainty ranging from a net cost of $756 million to net savings up to $8.50 billion. Conclusion This study evaluating the economic impact of egg consumption suggests that public health campaigns promoting limiting egg consumption as a means to reduce CHD risk would not be cost-effective from a societal perspective when other benefits are considered. Public health intervention that focuses on a single dietary constituent, and foods that are high in that constituent, may lead to unintended consequences of removing other beneficial constituents and the net effect may not be in its totality a desirable public health outcome. As newer data become available, the model should be updated.

The foods that trigger an inflammatory reaction and create coronary heart disease are also the ones that cause weight gain. And the main culprits that cause inflammation throughout your body, won't let you get rid of tummy fat, and damage your arteries, are the foods that are most abundant at your supermarket and that you may be eating every day.

Drinking more than one soda a day -- even if it's the sugar-free diet kind -- is associated with an increased incidence of metabolic syndrome, a cluster of risk factors linked to the development of diabetes and cardiovascular disease, a study finds
