The authors of the study noted that while the Western diet does not promote good cardiovascular health, it is not clear what effect fried foods may have on the risks of severe heart disease and stroke.
The researchers searched databases for any relevant studies published up to April 2020, finding 19 studies and collecting data from 17 of them. The studies included 562,445 participants and 36,727 major cardiovascular events, such as heart attack or stroke, which allowed the study authors to assess the risk of cardiovascular disease.
They then collected the data from 6 studies involving 754,873 participants and 85,906 deaths over an average study period of 9.5 years to assess the possible link between fried food consumption and deaths from disease. cardiovascular from any cause.
The analysis showed that, compared with the lowest proportion of weekly fried food consumption, the highest rate was associated with a 28% higher risk of major cardiovascular events, a 22% higher risk of coronary heart disease, and 37% higher risk for heart failure.
The associations remained true when stratified by different study and participant characteristics, and a linear association was found between fried food consumption and major cardiovascular events, coronary heart disease, and heart failure, according to the authors of the inspection. The risks increased 3%, 2%, and 12%, respectively, along with each additional weekly serving of 114 grams.
Several previous studies included only 1 type of fried food, such as fried fish, potatoes, or snacks, rather than whole fried foods, which may be have disregarded the associations found, the authors of the study noted.
No associations have been found for deaths from cardiovascular disease or for any reason, but this may be due to the relatively small numbers involved. Moreover, the design of the included studies varied significantly, and when added, they all relied on memory. These factors should be taken into account when interpreting the results, according to the authors of the study.
The authors of the study also noted that it is not entirely clear how fried foods may influence the development of cardiovascular disease, but this study helps to suggest other possible explanations. there.
