No associations were found with deaths from cardiovascular disease or from any cause, but the researchers said this may be due to the relatively small number involved in some studies.
When food is fried, it absorbs some of the fat from the oil, increasing the calorie count. Additionally, commercially fried and processed foods can often contain trans fats, created by an industrialized process that adds hydrogen to liquid vegetable oils to make them firmer (think semi-soft margarine and shortening).
The food industry likes trans fats because they are cheap to produce, last a long time and give food great taste and texture.
In addition to fried foods, you can find trans fats in coffee creamer, cakes, pie crusts, frozen pizzas, cookies, crackers, cookies, and dozens of other processed foods.
However, there is still a loophole. The FDA allows companies to label a food as “0 grams” of trans fats if a serving of the food contains less than 0.5 grams.
Only an association
Despite the evidence behind the health effects of trans fats, this meta-analysis of studies can only demonstrate a link between fried food consumption and cardiovascular risk.
The findings of this study are consistent with current guidelines to limit fried food intake, but cannot be considered definitive evidence for the role of fried food consumption in cardiovascular health, said Alun Hughes, professor of cardiovascular physiology and pharmacology at University College. London, in a statement. Hughes was not involved in the investigation.
That’s because most studies of these types of answers to the memory of the amount and type of fried foods eaten, which is prone to errors. In addition, high consumption of fried foods is likely associated with overeating and obesity, lack of exercise, and other unhealthy behaviors that can contribute to heart disease, experts said.
“If the relationship is causal, we cannot assume that this association is definitely related to the fat content of the foods, as many of these foods are highly processed and often contain both fat and carbohydrates,” said registered dietitian Duane Mellor. , a senior teacher at Aston Medical School in Birmingham, UK.
“So when considering this kind of research, it’s important to remember that while reducing fat intake is a logical part of a healthy diet, it’s also important to consider what foods are eaten instead,” said Mellor, who was not involved in the investigation.
