### Study Shows Mixed Results on Fish Oil Supplements and Heart Health
A recent study published in the journal BMJ Medicine suggests that while fish oil supplements may increase the risk of developing a heart condition or stroke in individuals without cardiovascular disease, they could potentially reduce the risk for those already diagnosed with heart issues. The study, conducted by a team of researchers from China, the US, the UK, and Denmark, monitored over 400,000 participants in the UK Biobank for an average of 12 years to assess the impact of fish oil supplements on heart health.
### Findings on Fish Oil Supplements
For participants without known cardiovascular disease at the beginning of the study, regular use of fish oil supplements was linked to a 13% higher risk of developing atrial fibrillation and a 5% higher risk of experiencing a stroke. However, for individuals with pre-existing heart conditions, fish oil supplements were associated with a 15% lower risk of progressing from atrial fibrillation to a heart attack and a 9% lower risk of transitioning from heart failure to death.
### Variances in Risk Based on Gender and Smoking Status
The study also observed variations in the effects of omega-3 supplementation based on gender and smoking status. Women and non-smokers showed a 6% higher risk of developing heart issues with fish oil supplements. Conversely, older individuals and men with existing heart conditions experienced a more significant reduction in the risk of transitioning from good health to death.
### Cautionary Notes and Dietary Recommendations
The authors of the study caution that the findings are observational, and no definitive conclusions can be drawn about causal factors. Additionally, the study lacked information on the specific dose or formulation of fish oil supplements used by participants. Tracy Parker, a senior dietitian at the British Heart Foundation, emphasized that while the study results are not cause for alarm, they do not endorse the use of fish oil supplements as a preventive measure for heart and circulatory diseases.
### Emphasis on Healthy Diet Choices
Parker highlighted the importance of a well-rounded, healthy diet over reliance on individual supplements. She recommended following a traditional Mediterranean diet rich in fish, fruits, vegetables, legumes, nuts, seeds, and whole grains to reduce the risk of heart attack or stroke. Ultimately, the study underscores the complex relationship between fish oil supplements and heart health, emphasizing the need for holistic dietary approaches to promote cardiovascular well-being.
