Also known as heart flutter, atrial fibrillation sis a heart rhythm irregularly. Keep reading for the full findings of the large-scale Swedish study.
Swedish study links regular nut consumption to a lower risk of heart problems
The study was conducted by a team of researchers from the Kaolinska Instituet and Uppsala University. The team looked at 61,364 Swedish adults between the ages of 45 and 83 who’d completed the Food Frequency Questionnaire, which asked questions about their diet, liestyle and other risk factors for chronic diseases.
The team followed the participants for a period of 17 years or until death – whichever came first – tracking their heart health. After taking the participants’ age and gender into account, the team found that nut consumption as linked to a lower risk of heart attack, heart failure, atrial fibrillation and abdominal aortic aneurysm, which is a swelling or bulge in a major artery known as the aorta.

Eating nuts is particularly protective against atrial fibrillation and heart failure
However, after the team took lifestyle, general diet, diabetes
and family history into account as well, only links between nut consumption and atrial fibrillation and heart failure remained. They found that the more nuts a participant ate, the lower there risk was of atrial fibrillation. Eating a serving of nuts on to three times a month was tied to a 3% reduction in risk, eating nuts once or twice a week was tied to a 12% reduction and eating nuts three or more times a week resulted in an 18% reduction.
The findings for an association between nut consumption and heart failure were less consistent, but it appeared that moderate – but not high – weekly nut consumption was associated with a 20% reduced risk.
