Food Additives and Their Impact on Human Health: A Review of Current Evidence

Food additives are chemical or natural substances intentionally incorporated into food products to improve shelf life, taste, color, texture, and overall quality. With the rapid expansion of processed and convenience foods, the use of food additives has increased substantially across the globe. Although most additives are approved by regulatory authorities and are considered safe when used within established limits, growing scientific literature suggests that excessive or long-term consumption may be associated with potential health concerns. This review summarizes the major classes of food additives used in the food industry, their technological functions, and the regulatory frameworks governing their use. Additionally, it examines the possible health implications linked with additive consumption, including allergic responses, metabolic alterations and behavioural effects in children, and potential long-term risks such as carcinogenicity and changes in gut microbiota. The review highlights both the benefits and the possible risks associated with food additives and emphasizes the importance of continued monitoring, scientific evaluation, and responsible consumption. Understanding the health effects of food additives is crucial for researchers, policymakers, and consumers in order to ensure food safety and promote healthier dietary practices.
