Why A High-Fat Diet Should Be Avoided?

People are usually advised not to have high-fat diet, as this would very likely make people become overweight or even obese. At the same time, it would increase the chance of developing many diseases including heart disease, high blood pressure, and stroke.

A study, believed to be the largest to look at stroke risk in women and across all types of fat, revealed that eating a high-fat diet especially trans fats, could raise the risk for ischemic stroke in postmenopausal women. Ischemia stoke is the most common type of stoke caused clogged blood vessels supplying the brain.

Women who aged 55 and above and ate the most total fat, including monounsaturated and polyunsaturated fats as well as trans and saturated fats, had a 44 percent higher risk of ischemic stroke, as compared to those who ate the least. Meanwhile, women who consumed the highest amount of trans fat had a 30 percent more likely to get ischemic stroke, compared with those who consumed the least.

Researchers from the University of North Carolina, Chapel Hill presented their findings on February 24, 2010 at the American Stroke Association International Stroke Conference 2010.

Previous studies had linked trans fat to the development of coronary heart disease, but studies on the association of ischemic stroke and fat have been inconclusive.

87,230 participants in the Women's Health Initiative, which is a federally funded study for revealing health risks from taking hormone pills for menopause symptoms, were involved. Participants, between the age of 50 and 79, were asked to fill out detailed surveys on their diets when they enrolled. They were divided into 4 groups based on how much fat they ate, and were followed for an average of 7.6 years to see how many had suffered ischemia stroke. A total of 1049 ischemic strokes were found among the women.

It has been known that postmenopausal women would face a higher risk of ischemic stroke than men of the same age. Before menopause, women have a lower risk of stroke than men of similar age. Nevertheless, their risk doubles every 10 years after the age of 55.
