Women who eat fried chicken every day may be 13% more likely to die prematurely than people who avoid these foods, suggests an American study.
The fried fish is only slightly better, with 7% more risk of premature death for all causes associated with a daily service, according to the study.
"Eating fried foods increases total caloric intake and risk of obesity, which is associated with a higher risk of death," said senior author Wei Bao, from the University of Iowa, at Iowa City.
"However, in our analysis, we have represented total calorie intake, living habits and the obesity state," Bao said via e-mail. "After controlling these factors, the association of fried foods with death was maintained for any reason and cardiovascular death."
As many as three adults in North America eat fast food, usually fried, every day, Bao and his colleagues stand out in the BMJ.
During cold, foods can lose water and absorb fat, which can make meals more cruel and appetizing, but also encourage people to eat more than they should. Previous research has linked fried foods to a higher risk of obesity, heart disease and diabetes, but the potential connection to premature death is unclear.
For the current study, the researchers examined data from the diet questionnaire of 106,966 women aged 50 to 79 who participated in the study of the Women's Health Initiative between 1993 and 2017.
On average, the researchers followed each woman for about 18 years. During the follow-up, 31,588 women died, among which 9,320 died of cardiac problems and 8,358 died of cancer.
To evaluate the consumption of fried foods, the researchers observed the frequency with which women reported some articles when they enrolled in the study, including: "fried chicken"; "Fried fish, fish sandwich and fried seafood (shrimp and oysters)"; and other fried foods, such as chips, tortillas and tacos.
After explaining other factors that could accelerate death, such as limited education, inactivity and generally unhealthy diet, researchers found that fried foods were commonly associated with a high risk of death for anyone cause and, specifically, for cardiac problems.
Women who ate at least one serving of fried chicken were 12% more likely to die of heart problems than women who did not eat fried foods, found the study. Fries, on the other hand, were associated with 13% more risk of death due to cardiac problems.
But eating fried foods did not seem to impact the risk of dying from cancer.
Participants who ate fried foods more often tended to be younger, not white, with less education and lower income. They were also more likely to be smokers, exercise less and have a low quality diet.
The study was not a controlled experiment to show that fried foods directly influence longevity. Another drawback is that he trusted women to accurately remember everything they ate.
Even so, the results offer new evidence of how food is prepared can have a great impact on health, said Dr. Clyde Yancy of the Northwestern University Feinberg School of Medicine in Chicago.
"Poultry and fish are generally considered" heart-healthy "dietary options, but the frying process changes the health consequences," said Yancy, who did not participate in the study, by e-mail
"When fried foods are consumed, the altered structure of these fats used for colds generates signs for increased inflammation, more (hardening of the arteries) and more blood sugar," Yancy added . "This only aggravates when ingestion of fried foods is associated with drinks with sweetened sugar, high sodium content, and less consumption of vegetables and fruits."
Avoiding fried foods may be ideal, but some fried methods may be better than others, said Daniel Lackland, a researcher at the Medical University of South Carolina at Charleston who did not participate in the study.
"The removal of trans fat is important," said Lackland by email. "Consuming grilled or baked foods would be the preferred option, but if occasional fried foods are consumed, frying with safer oils as olive oil would be a good way to" to go".
