Exposure to food dyes occurs during most meals that people eat every day, and these dyes can have certain effects on the human body. Many consumers show no signs of being affected by food dyes; however, some specific diseases and disorders, such as ADHD, can be aggravated by dyes in addition to general complaints such as nausea, headaches, and irritability (Walford, 1984). Both natural and synthetic dyes can cause reactions, and about fifty years ago strict regulations on color additives and their certification were implemented due to several studies on dyes and several cases of severe allergic reactions (Vargas & Lopez, 2003). However, not all food colorings are harmful to physical health. The development of nutritionally beneficial food additives is an area of ​​science that is advancing rapidly. Although many food dyes may be harmful to human health, nutritionists are becoming increasingly familiar with the beneficial properties of dyes and the prospect of eating a healthier diet is encouraging (Downham & Collins, 2000). used as a food additive, testing should be performed to determine its toxicological effects. Many food dyes have been shown to induce certain diseases and carcinogenic or allergic reactions in animals and humans. By the 1960s, experiments had shown results that initiated regulations limiting the use of these dyes (Vargas & Lopez, 2003). However, some natural dyes, i.e. those pigments recovered from living organisms, are believed to have fewer negative effects on consumer health and have fewer restrictions on their use than synthetic dyes,... half of the paper... .35( 1): 5-22.
