Cardiovascular diseases from fried food? – healing practice

Relationship Between Fried Foods and Heart Disease

French fries, chicken nuggets, fish fingers, pastries such as donuts and donuts – fried food is an integral part of the diet for many. But it is as popular as it is unhealthy. A current study now shows that regular consumption of fried foods is associated with an increased risk of developing cardiovascular diseases.

Researchers from Shenzhen (China) evaluated the data from various epidemiological studies over the past few years. It found that eating fried foods was associated with an increased risk of serious heart disease and stroke. Even small amounts from a regular weekly consumption of 114 grams seem to increase the risk. The results of the meta-analysis were recently presented in the journal “Heart”.

How unhealthy is fried food really?

Most people are well aware that many fried foods are not healthy. It is not known in detail what the regular consumption of fat-soaked foods actually causes and what contribution this food makes to the development of severe heart disease and strokes. The meta-analysis of various data from nutrition studies should shed more light on this.

What was investigated?

The researchers summarized 17 studies, which contained a total of data from 562,445 participants, including 36,727 serious cases of cardiovascular events such as heart attack or stroke, to assess the potential association between the consumption of fried foods and cardiovascular disease.

Risk from fried food

The analysis shows that the group of people with the highest consumption of fried foods had a 28 percent increased risk of major cardiovascular events, a 22 percent increased risk of coronary heart disease and a 37 percent increased risk of heart failure compared to the group with the had the lowest consumption of fried food.

Linear increase in risk

In addition, the data showed a linear relationship between the amount of fried foods regularly consumed and the associated risk of heart disease. The risk increased with each weekly serving of 114 grams.

Why do fried foods have this effect?

How exactly fried foods affect the development of cardiovascular disease was not investigated in this study. This could be the subject of future research. It would also be possible, for example, that a high consumption of fried foods is a general marker of an unhealthy lifestyle.

Possible reasons for the unhealthy effects

Nevertheless, according to the researchers, there are plausible possible reasons for this unhealthy effect: On the one hand, fried foods have a high calorie content and contain many trans fats, which are considered the most unhealthy fats (more information in the article: “Hydrogenated fats – trans fats”). On the other hand, chemical by-products are created during deep-frying, which can trigger inflammatory reactions in the body. In addition, the fried foods are often heavily salted or sugared. (vb)

Editor’s note: The headline of an earlier version of this article suggested a causal link between fried food and cardiovascular disease, which has not yet been scientifically proven. The heading has therefore been corrected accordingly.
