TUESDAY, Jan. 24 (HealthDay News) — Researchers in Spain have
some good news for people who enjoy eating fried food: Cooking in olive or
sunflower oil is not linked to heart disease or premature death.
Because heart disease risk factors — such as high blood pressure, high
cholesterol and obesity — have been linked to eating fried foods, the
study authors decided to investigate the association.
For the study, the researchers examined the cooking habits and health
of nearly 41,000 adults, aged 29 to 69, who did not have heart disease at
the start of the 11-year study. The participants were split into four
groups depending on how much fried food they consumed.
The study authors pointed out that because their research was conducted
in Spain, where olive and sunflower oil are used for cooking, the findings
may not apply in other countries where other types of oil are more
commonly used. For example, when food is fried in solid and re-used oils
(as in the Western diet), it absorbs the fat of the oils, which increases
the calories of the food.
There were 606 heart disease-related events and 1,134 deaths during the
study follow-up period, according to the report published in the Jan. 24
online edition of the BMJ.
“In a Mediterranean country where olive and sunflower oils are the most
commonly used fats for frying, and where large amounts of fried foods are
consumed both at and away from home, no association was observed between
fried food consumption and the risk of coronary heart disease or death,”
according to the research team, led by Pilar Guallar-Castillon from
Autonomous University of Madrid.
In an accompanying editorial, Michael Leitzmann, from the University of
Regensburg in Germany, wrote that the findings challenge the belief that
“frying food is generally bad for the heart.”
However, he added that this “does not mean that frequent meals of fish
and chips will have no health consequences.” Specific aspects of frying
food, such as the type of oil used, are important, Leitzmann noted.
