Eating fish helps your live longer
The ultimate goal of any healthy behavior is to lead a longer, better life, right? According to researchers from the Harvard School of Public Health and the University of Washington, eating two weekly servings of fish rich in omega-3 fatty acids can help increase life expectancy by an average of 2.2 years. Among elderly adults with high blood levels of omega-3s, all mortality was reduced by 27 percent and the risk of dying from heart disease was lowered by 35 percent.
Earlier research has found that eating fish rich in protein and heart-healthy omega-3 fatty acids can reduce the risk of dying from heart disease. This study focused on the level of omega-3s in the blood and how this affects the length of life in older adults. The study authors compiled 16 years of data from nearly 2,700 adults aged 65 and over, all of whom were healthy at the time of baseline testing. The scientists took three blood samples and tested for fatty acids in each, finding that three different omega-3s were each linked to significantly lowered risk of mortality.
Fatty acid docosahexaenoic acid (DHA) lowered risk of heart disease by 40 percent. Docosapentaenoic acid (DPA) significantly lowered stroke risk and eicosapentaenoic acid (EPA) significantly lowered the risk of nonfatal heart attack.
Seafood high in omega-3s include salmon, mackerel, sardines, swordfish, mussels and oysters.
