Moderate fish consumption (up to 5+ meals/week) does not reduce the risk of myocardial infarction, stroke, or cardiovascular death in middle-aged to older men.
If you are a healthy man, eating fish several times a week is unlikely to lower your risk of heart attack or stroke based on this 4-year study. While fish is a healthy food, relying on it as a primary strategy to prevent cardiovascular disease is not supported by this evidence. Focus on proven risk factor management (blood pressure, cholesterol, smoking) rather than expecting fish to act as a shield.
These data do not support the hypothesis that moderate fish consumption lowers the risk of cardiovascular disease.
Why this rating
Large prospective cohort (n=21,185), rigorous endpoint confirmation, but limited follow-up (4 years) and self-reported diet.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
