The Claim
In US adults with a prior diagnosis of myocardial infarction, higher intake of polyunsaturated fatty acids is not associated with reduced heart disease mortality, based on data from 1,541 individuals, suggesting that PUFA intake may not provide the same survival benefit in secondary prevention as observed in primary prevention populations.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you've already had a heart attack, eating more healthy fats like those in fish or nuts might not help you live longer — at least that's what one study found in American adults.
See the scientific wording
The inverse association between polyunsaturated fatty acid intake and heart disease mortality is not observed in US adults with a prior diagnosis of myocardial infarction, based on data from 1,541 individuals, suggesting that PUFA intake may not confer the same survival benefit in secondary prevention.
What the research says
1 studyStudy: Dietary fatty acids and mortality risk from heart disease in US adults: an analysis based on NHANES
The study found that eating more healthy fats (PUFAs) lowers heart disease risk for most people, but not for those who already had a heart attack, which is exactly what the claim says.
