People age 65 and older who eat fish may live an average of two years longer than people who do not consume the omega-3 fatty acids found mainly in seafood, a US study suggested on Monday.
.
People with higher levels of omega-3 fatty acids also had an overall risk of dying that was 27 percent lower, and a risk of dying from heart disease that was 35 percent lower than counterparts who had lower blood levels, said the study.
.
The research was led by scientists at the Harvard School of Public Health and was published in the Annals of Internal Medicine.
.
While other studies have demonstrated a link between omega-3 fatty acids and lower risk of heart disease, this research examined records of older people to determine any link between fish- eating and death risk.
this is a nice information. To add to this, eating fruits and laughing also increases longeivity.
