Frequent consumption of trans fats increases the risk of stroke in postmenopausal women, according to a new study from the University of North Carolina at Chapel Hill.
The researchers also found that regular aspirin intake led to a significantly lower risk of developing the condition.
However, the use of aspirin does not reduce the risk of stroke in women whose diet includes trans fats, said the research team.
The researchers analyzed the eating habits of 87,000 women aged 50 to 79 years.
Within a 7-year period, 1,049 cases of stroke were registered.
According to the results, high consumption of trans fats increases the risk of the condition by 39%. It is also found that women who have other unhealthy habits associated with lack of physical activity and smoking, there is an increased risk of developing diabetes.
No link has been found between the consumption of other types of fat and ischemic stroke, the researchers said.
Trans fats also help increase the risk of developing heart disease by increasing "bad" cholesterol and lowering levels of "good" cholesterol.
To avoid the development of heart disease and stroke, experts recommend limiting processed foods in which the content of these fats is extremely high.
Risk factors for stroke include obesity, smoking, hypertension, lack of exercise, and alcohol abuse.
The results are published in the Annals of Neurology .
Another study shows that trans fats are also a risk factor for developing breast cancer. It has been found that women with high levels of the lipids in question have twice the risk of the disease.
