Story summary

Using data from the U.S. National Health and Nutrition Examination Survey (NHANES), researchers found a significant negative association between omega-3 intake and all-cause mortality in patients with cardiovascular disease.
The effect was strongest for alpha-linolenic acid (ALA).
An optimal intake of 2.12 grams per day was suggested for CVD patients.
However, the observational nature of the study limits conclusions, and causation cannot be established, calling for further research.
