Replacing 5% of energy from saturated fat with polyunsaturated fat was associated with a 27% lower risk of death in men and women over the next 22-26 years according to a study from researchers at Harvard University in Boston, Massachusetts, USA.
Foods High in Saturated Fat
Saturated fat is found in foods such as beef, lamb, pork, chicken with skin, lard, cream, butter and cheese.
Foods High in Polyunsaturated Fat
Polyunsaturated fat is found in high amounts in foods such as walnuts, flaxseeds and flaxseed oil, grapeseed oil, safflower oil, sunflower oil, sunflower seeds, wheat germ oil, sunflower oil, and fatty fish such as salmon, mackerel, herring and trout.
Subjects: 83,349 women followed for 22 years, 42,884 men followed for 26 years
The study investigated 83,349 women from the Nurses’ Health Study (July 1, 1980, to June 30, 2012) and 42,884 men from the Health Professionals Follow-up Study (February 1, 1986, to January 31, 2012) who were free of cardiovascular disease, cancer, and types 1 and 2 diabetes at baseline.
“These findings support current dietary recommendations to replace saturated fat and trans-fat with unsaturated fats,” the authors of the study concluded.
