There has been extensive research showing that moderate consumption of chocolate, particularly dark chocolate, improves markers of cardiovascular health5 and is associated with a lower rate of myocardial infarction,6 heart failure,7 ,8 composite cardiovascular adverse outcome and cardiovascular mortality.9

Conclusions Accumulating evidence indicates that moderate chocolate intake may be inversely associated with AF risk, although residual confounding cannot be ruled out.

The higher flavonoid content of dark chocolate compared with milk chocolate may yield greater cardiovascular benefits. … In addition, flavanol content and total antioxidant capacity in plasma may be lower if cocoa is consumed with milk or if cocoa is ingested as milk chocolate.26 Furthermore, cocoa is usually consumed in high calorie products that use fat and sugar, and modern manufacturing of chocolate may result in losses of more than 80% of the original flavonoids from the cocoa beans.27 Therefore, it may be advantageous to find ways to consume cocoa in forms other than chocolate bars. The ongoing Cocoa Supplement and Multivitamin Outcomes Study is a large randomised trial testing the effect of a concentrated cocoa extract on cardiovascular risk, and may provide insight on the efficacy and feasibility of ingesting cocoa in this form.

In the European Union, milk chocolate must contain a minimum of 30% cocoa solids and dark chocolate must contain a minimum of 43% cocoa solids

Eating 2-6 servings of dark chocolate a week could cut risk of Irregular Heartbeat, study finds

Psychological Distress Across the Life Course and Cardiometabolic Risk

Psychological Distress Across the Life Course and Cardiometabolic Risk
Findings From the 1958 British Birth Cohort Study
Ashley Winning, ScD, MPH, et al.
J Am Coll Cardiol. 2015;66(14):1577-1586.
http://content.onlinejacc.org/article.aspx?articleID=2445329

Background  Research suggests cardiovascular and metabolic diseases are influenced by psychological distress in adulthood; however, this research is often limited to adult populations and/or a snapshot measure of distress. Given emerging recognition that cardiometabolic diseases have childhood origins, an important question is whether psychological distress earlier in life influences disease development.

Objectives  This study sought to assess whether life course patterns of psychological distress assessed from childhood through adulthood predict biomarkers of cardiometabolic risk in adulthood and whether effects of sustained distress differ from more limited exposure.

Methods  The sample (n = 6,714) consists of members of the 1958 British Birth Cohort Study who completed repeated measures of psychological distress and a biomedical survey at age 45 years. Psychological distress profiles over the life course (no distress, childhood only, adulthood only, or persistent distress) were identified from 6 assessments between ages 7 and 42 years. Cardiometabolic risk was assessed by combining information on 9 biomarkers of immune, cardiovascular, and metabolic system function. Covariate adjusted linear regression models were used to assess associations between distress profiles and cardiometabolic risk.

Results  Compared with those with no distress, cardiometabolic risk was higher among people with psychological distress in childhood only (β = 0.11, SE = 0.03, p = 0.0002), in adulthood only (β = 0.09, SE = 0.03, p = 0.007), and persistent across the life course (β = 0.26, SE = 0.04, p < 0.0001).

Conclusions  Psychological distress at any point in the life course is associated with higher cardiometabolic risk. This is the first study to suggest that even if distress appears to remit by adulthood, heightened risk of cardiometabolic disease remains. Findings suggest early emotional development may be a target for primordial prevention and for promoting lifelong cardiovascular health.

Type A personality: a construct of the tobacco industry

The Secret History Behind The Science Of Stress

both Selye’s work and much of the work around Type A, were profoundly influenced by cigarette manufacturers who were interested in promoting the concept of stress because it allowed them to muddy the waters by arguing that it was stress and not cigarettes that was to blame for heart disease and cancer.

PETTIGREW: In the case of Selye, tobacco industry lawyers vetted papers. They vetted the content of the paper. They agreed the wording of papers. Tobacco industry lawyers actually influenced the content of his writings. They suggested to him things that he should comment on.

“What’s never really been appreciated is that the tobacco industry was a major funder and stimulant of research on stress,” he says. “Specifically Selye’s work, but also research on Type A behavior. Type A personality is to a large extent a construct of the tobacco industry.”

I never had any procrastination issues and a lot of my writer friends had procrastination issues, deadline issues, and they were really tortured by magazine writing.

So I think for the most part they really admired the fact that I could just kind of get in there workman-like, knock it out, and go home and go back to fiction.

Red meat consumption and mortality

Red meat consumption and mortality: results from 2 prospective cohort studies.
Arch Intern Med. 2012 Apr 9;172(7):555-63.
Pan A, et al.
http://www.ncbi.nlm.nih.gov/pubmed/22412075

BACKGROUND:
Red meat consumption has been associated with an increased risk of chronic diseases. However, its relationship with mortality remains uncertain.

METHODS:
We prospectively observed 37 698 men from the Health Professionals Follow-up Study (1986-2008) and 83 644 women from the Nurses’ Health Study (1980-2008) who were free of cardiovascular disease (CVD) and cancer at baseline. Diet was assessed by validated food frequency questionnaires and updated every 4 years.

RESULTS:
We documented 23 926 deaths (including 5910 CVD and 9464 cancer deaths) during 2.96 million person-years of follow-up. After multivariate adjustment for major lifestyle and dietary risk factors, the pooled hazard ratio (HR) (95% CI) of total mortality for a 1-serving-per-day increase was 1.13 (1.07-1.20) for unprocessed red meat and 1.20 (1.15-1.24) for processed red meat. The corresponding HRs (95% CIs) were 1.18 (1.13-1.23) and 1.21 (1.13-1.31) for CVD mortality and 1.10 (1.06-1.14) and 1.16 (1.09-1.23) for cancer mortality.
We estimated that substitutions of 1 serving per day of other foods (including fish, poultry, nuts, legumes, low-fat dairy, and whole grains) for 1 serving per day of red meat were associated with a 7% to 19% lower mortality risk. We also estimated that 9.3% of deaths in men and 7.6% in women in these cohorts could be prevented at the end of follow-up if all the individuals consumed fewer than 0.5 servings per day (approximately 42 g/d) of red meat.

CONCLUSIONS:
Red meat consumption is associated with an increased risk of total, CVD, and cancer mortality.
Substitution of other healthy protein sources for red meat is associated with a lower mortality risk.

BP in Relation to Coffee Consumption

Blood Pressure in Relation to Coffee and Caffeine Consumption
Current Hypertension Reports, August 2014, 16:468

The relationship between blood pressure (BP) and coffee is of major interest given its widespread consumption and the public health burden of high BP.
Yet, there is no specific recommendation regarding coffee intake in existing hypertension guidelines.
The lack of a definitive understanding of the BP-coffee relationship is partially attributable to issues that we discuss in this review, issues such as acute vs. chronic effects, genetic and smoking effect modifications, and coffee vs. caffeine effects.

We also present evidence from meta-analyses of studies on the association of BP with coffee intake.
The scope of this review is limited to the latest advances published with a specific focus on caffeine, acknowledging that caffeine is only one among numerous components in coffee that may influence BP.

Finally, considering the state of the research, we propose a mechanism by which the CYP1A2 gene and enzyme influence BP via inhibition of the adenosine receptor differentially in smokers and non-smokers.

Marathon Training Lowers Heart Disease Risk

Impact of Physical Activity on CV Disease
March 29, 2014

Another study of physical activity concluded that marathon training improved cardiovascular risk factors among middle-aged, recreational runners who prepared for the Boston Marathon.
Jodi L. Zilinski, MD, of Massachusetts General Hospital led the study of 45 male runners, ages 35 to 65, who trained for 18 weeks in advance of the 2013 marathon.
Their race preparation led to significant changes in cardiovascular risk: LDL was reduced by five percent overall among participants; total cholesterol fell four percent and triglycerides fell 15 percent.
The men collectively showed a four percent increase in peak oxygen consumption.

“Participants experienced cardiac remodeling,” Zilinski said. “Even with a relatively healthy population that was not exercise naive.”

http://www.nejm.org/doi/full/10.1056/NEJMoa1106468
Conclusions:
Marathons and half-marathons are associated with a low overall risk of cardiac arrest and sudden death.
Cardiac arrest, most commonly attributable to hypertrophic cardiomyopathy or atherosclerotic coronary disease, occurs primarily among male marathon participants; the incidence rate in this group increased during the past decade.
