New Study Finds Correlation Between Almond Intake and General Heart Health

Karolinska Institute researchers found a correlation between eating different kinds of nuts per week, including almonds, and lower chances of developing a heart arrhythmia and heart flutter.

The Study

In this study, more than 1,500 studies on almond intake and heart health were reviewed. The conclusion of the study was that including almonds in your diet is correlated with lowered dyslipidemia, among the most important factors that determine your risk of developing cardiovascular disease.

The scientists used the responses written for the Food Frequency Questionnaire for over 60,000 participants, all aged between 45 and 83 years old. They then followed up on the participants for 17 years (or until they died). They found a correlation between nut intake, high education levels, and healthier lifestyles.

People who consumed nuts also tended not to smoke, have high blood pressure, nor a history of high blood pressure. They tended to be relatively lean, higher in physical activity, consumed higher levels of alcohol as well as fruits and veggies.

It was also linked to lower risks for heart complications such as heart attacks, atrial fibrillation, heart failure and abdominal aortic aneurysm. The study also factored age and gender into account.

What Exactly Does This All Mean?

However, when some other factors were taken into account, such as diabetes, lifestyle, diet and family history, the only correlations that could accurately be made with nut consumption was a lowered risk for atrial fibrillation and heart failure.

It was also found to help regulate blood sugar.

“Research shows that almonds, which are a source of protein and high in dietary fibre, can help in maintaining healthy blood sugar levels, may improve blood sugar control in people with type 2 diabetes, and help lower the blood sugar impact of carbohydrate foods, which affects fasting insulin levels,” Ritika Samaddar, a nutrition expert said.

It’s also important to note that correlation does not necessarily imply causation. The study showed a correlation between nuts and a lowered risk for atrial fibrillation and heart failure. However, this does not mean that nut consumption is what caused this lowered risk, but just that nut consumption and these lowered risks were often found together non-coincidentally throughout the study.
