Abstract
Food additives, such as sweeteners and food colorants, play an important role in the food supply. But despite their widespread use in food, there are always concerns about their side effects on consumer health, and their excessive use can lead to adverse effects. This study aims to provide a brief overview of the beneficial and harmful effects of some sweeteners and food colorants on human health. For this purpose, studies conducted on these food additives from 2001 to 2025 were reviewed. Related articles were collected by using the keywords "food additives, sweeteners, colorants, and health effects." From scientific databases such as Pubmed, Science Direct, Elsevier, SID, etc. The results of studies have shown that artificial sweeteners and colorants, despite their widespread use in industry, can compromise food safety and lead to side effects such as gastrointestinal disorders, allergies, and even cancer in consumers. On the other hand, with the increase in consumer awareness, the demand for natural additives has increased. Therefore, dyes and artificial sweeteners should be limited, and their natural types should be used instead.
