Methods
This was a prospective study in Sweden where 61,364 men and women completed food frequency questionnaires in 1997 and were followed for 17 years. Authors examined the effect of nut consumption on seven cardiovascular diseases: acute myocardial infarction, heart failure, atrial fibrillation, aortic valve stenosis, abdominal aortic aneurysm, ischaemic stroke, and intracerebral hemorrhage. In this stuy nuts were grouped into one category, nuts/almonds. This category excluded coconuts and chestnuts.
Key Findings
The study showed that nut consumption three or more times per week was associated with an 18% reduced risk of atrial fibrillation. A moderate consumption (up to 1-2 times/week) was associated with reduced risk of heart failure.
