Eating fish reduces the risk of heart disease PHOTO: Petpooja
A new study conducted by an international group of scientists from several universities in Italy, Africa of the South, Spain and China, published in the journal Nutrients on October 26, 2023, made an important discovery about a special food that brings unknown health benefits. Experts have found that eating fish significantly reduces the risk of heart disease and stroke.
Studies show that unhealthy eating habits and sedentary lifestyles contribute to high mortality rates from cardiovascular disease worldwide. And recent research reveals that eating fish can greatly reduce the risk of cardiovascular disease and related premature mortality, according to News Medical.
In the present meta-analysis, researchers assessed the impact of fish consumption on heart disease risk outcomes. Using the random-effects approach, researchers synthesized data from multivariate-adjusted relative risk (RR) values of high versus low fish consumption categories on the incidence of cardiovascular disease and associated deaths.

Of the 2,413 records initially identified, 2,348 were eliminated after title-abstract screening. As a result, 65 studies remained, of which 18 eligible studies, conducted in the Netherlands, were analysed. United StatesDenmark, Sweden, Italy, Spain, Germany, Australia, Japan and China. Median values for participant age, proportion of men, sample size and follow-up times were 56 years, 45% and 36,713 people and 12 years, respectively.
The most frequently documented cardiovascular diseases were myocardial infarction (median of 1123 cases), stroke (median of 674 cases) and coronary heart disease (median of 307 cases).
The meta-analysis analyzed 78,805 cardiovascular disease events in a pooled population of 1,442,407 individuals over 18,926,486.0 pooled person-years. High versus low fish consumption was linked to an eight percent reduced risk of cardiovascular disease (RR of 0.9).
Meta-regression analysis indicated that 50 grams of fish consumed daily significantly reduced the risk of life-threatening and non-life-threatening cardiovascular disease by nine percent (RR, 0.9), denoted by a curve in monotonically decreasing S-shape.
Also, eating two to three 150-gram servings of fish weekly reduced the risk of cardiovascular disease by eight percent (RR, 0.9), and eating a full-size serving of fish daily may reduce the risk of cardiovascular diseases by 30%.
High consumption of fatty fish significantly reduced the risk of fatal and nonfatal cardiovascular disease by 12%, likely due to the high content of omega-3 polyunsaturated fatty acids, such as eicosapentaenoic acid and docosahexaenoic acid, which reduce platelet aggregation and inflammation.
