Eating oily fish like salmon, anchovies or sardines twice a week could increase omega-3 levels by 1%, which is all a person needs to add nearly five years to their life expectancy, scientists say. 

The study by researchers from the Hospital del Mar Medical Research Institute in Spain and The Fatty Acid Research Institute in the U.S. discovered that only a 1% increase in omega-3 levels in red blood cells reduces a person’s risk of death as much as quitting smoking. Researchers concluded that measuring these levels in the blood can be an extremely effective tool for calculating life expectancy.

Four types of fatty acids contribute positively to life expectancy, including two saturated fatty acids. Although many health experts advise people to stay away from saturated fats, suggesting a link to heart disease, recent studies show some saturated fats can help people stay healthy.
