| Summary: | This review focuses on the potential health risks of artificial food additives, especially their effects on lung health. Preservatives, synthetic colorants, and flavor enhancers, which are commonly used in processed foods, play roles in worsening respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD). These additives cause oxidative stress, systemic inflammation, and immune dysregulation, often through the gut-lung axis. The preservatives sodium nitrite and sulfites have the risk of causing bronchial hyper-responsiveness and allergic reactions. The synthetic colorant, Ponceau 4R, is also related to immune-mediated lung inflammation. Flavoring agents such as diacetyl contribute to occupational respiratory diseases like bronchiolitis obliterans. In animal models, prenatal exposure to additives, such as titanium dioxide (E171), might disrupt the development of respiratory neural networks, with long-term consequences. Ultra-processed foods (UPFs), which also contain a high concentration of additives, lead to systemic inflammation and impair lung function. Despite their wide usage, the use of these additives has become a warning sign due to their safety issue, particularly in sensitive people like children, pregnant women, and patients with pre-existing respiratory and chronic conditions. The review highlights the serious need for strict regulation and further research on the long-term effects of food additives on respiratory health. Policymakers should ban these food additives that are more harmful to human health. As an alternative to artificial additives, natural flavors and colors from fruits and vegetables, safe preservatives, and minimally processed ingredients can be used. |
