Eating regular variety of nuts associated with lower risk of heart disease

People who regularly eat nuts, including peanuts, walnuts and tree nuts, have a lower risk of developing cardiovascular disease or coronary heart disease compared to people who never or almost never eat nuts, according to a new study. The study is the largest to date looking at frequency of nut consumption in relation to incident cardiovascular disease.

The study found a consistent inverse association between total nut consumption and total cardiovascular disease and coronary heart disease. Also, after looking at individual nut consumption, eating walnuts one or more times per week was associated with a 19 percent lower risk of cardiovascular disease and 21 percent lower risk of coronary heart disease. Participants who ate peanuts or tree nuts two or more times per week had a 13 percent and 15 percent lower risk of cardiovascular disease, respectively, and a 15 percent and 23 percent, lower risk of coronary heart disease, respectively, compared to those who never consumed nuts.

Participants who consumed five or more servings of nuts a week had a 14 percent lower risk of cardiovascular disease and a 20 percent lower risk of coronary heart disease than participants who never or almost never consumed nuts. The results were similar when accounting for consumption of tree nuts, peanuts and walnuts individually. Researchers found no evidence of an association between total nut consumption and risk of stroke, but eating peanuts and walnuts was inversely associated with the risk of stroke. Peanut butter and tree nuts were not associated with stroke risk.

So that bowl of nuts on the bar?  Yes, eat them.

Race Ranks Higher than Pounds for South Asians, Hispanics – ScienceDaily

Americans of South Asian descent are twice as likely as whites to have risks for heart disease, stroke and diabetes, when their weight is in the normal range, according to a study headed by Emory University and UC San Francisco.

Similarly, Americans of Hispanic descent were 80 percent more likely than whites to suffer from so-called cardio-metabolic abnormalities that give rise to heart disease, stroke and diabetes, compared with 50 percent more likely for those who were Chinese and African-American.

These risks include high blood pressure (hypertension), elevated glucose, low HDL, the “good cholesterol,” and high triglycerides, a fat found in blood. In the study, participants who were aged between 45 and 84, were classified as having cardio-metabolic abnormalities if they had two or more of these four risk factors.

If you don’t drink alcohol, start drinking to reduce your risk of cardiac diseases.

If you drink alcohol heavily, decrease consumption to reduce your risk of cardiac diseases.

Conclusions: Treatment with rosuvastatin at a dose of 10 mg per day resulted in a significantly lower risk of cardiovascular events than placebo in an intermediate-risk, ethnically diverse population without cardiovascular disease.

JAMA Cardiology – Effect of the Presence and Type of Angina on Cardiovascular Events in Patients Without Known Coronary Artery Disease Referred for Elective Coronary Angiography

This study describes the characteristics of patients referred for typical, atypical, or no angina and examines the associations between angina type, pre–cardiac catheterization stress test results, and burden of coronary atherosclerosis identified on coronary angiography.

In this short research letter we find further lack of utility for stress tests in the manner for which we are currently using them for risk stratification. The authors categorized patients referred for catheterization without known CAD to groups based on chest pain symptoms of: typical, atypical, or absent. They then looked at their stress test results, categorized as positive or negative, and found that a negative stress test did not help predict those without obstructive CAD on catheterization. Specifically, patients with typical angina symptoms and a negative stress test were the MOST likely to have obstructive CAD (74%). Clearly limited by the nature of the data presented, and the limited information given regarding the methodology in this research letter, it does further raise doubts regarding the utility of stress testing to risk stratify patients for CAD.
