A review and analysis of other scientific studies published so far have revealed a link between fast food consumption and an increased likelihood of developing asthma, wheeze, and other allergic diseases such as hay fever (pollen allergy), eczema and rhinoconjunctivitis.
This new report, published in the journal Respirology, has included a total of 16 studies on the issue. Among the different types of fast food consumption, hamburger intake three or more times a week has been more clearly associated with severe asthma and wheezing, compared to moderate consumption of once or twice every seven days.
“In conclusion, fast food consumption, particularly hamburgers, correlates with asthma in a dose-response pattern, which needs to be further validated in longitudinal and interventional studies,” said the lead author of this review, Dr. Gang Wang, of the West China Hospital at Sichuan University in China.
Fast food, associated with an increased likelihood of asthma and other allergies
The pattern is repeated in all the foods with abundant fats, high in refined carbohydrates, sodium, sugar, cholesterol, additives such as preservatives and colorants, and high concentrations of saturated fat.
Thus, scientists associated the fast food with allergic diseases depending on the weekly dose. However, the researchers have found differences between consumers discriminating by their income.
For example, a higher correlation has been associated with fast food consumption and asthma in high- and upper-middle-income countries.
Not only fast food but also a poor-quality diet can increase the risks of developing asthma and allergies
The authors of this new review pointed out that a poor-quality diet is also likely to contribute to the development and progression of asthma and wheeze through multiple mechanisms.
However, more studies are needed to what extent are fast food and a poor-quality diet influencing the occurrence of asthma and allergies.
“Further studies are needed to confirm the relationships seen in this analysis to identify possible causal associations between fast food consumption and allergic disease,” Gang Wang said.
