Food dyes are used to make food more appetizing. USFDA permitted nine artificial colorings in foods, drugs, and cosmetics, whereas the European Union (EU) approved five artificial colors (E-104, 122, 124, 131, and 142) for food. However, these synthetic coloring materials raise various health hazards.
The toxic effects of food dyes are on the brain, liver, kidney, lungs, urinary bladder, and thyroid gland. Blue 1 causes kidney tumor in mice, and there is evidence of death due to ingestion through a feeding tube. Blue 2 and Citrus Red 2 cause brain and urinary bladder tumors, respectively, whereas other coloring additives may cause different types of cancers and numerous adverse health effects.

We hope that the data collected from in vitro or in vivo studies and from clinical investigations related to the possible health hazards of food color additives will be helpful to both researchers and the food industry in the future.
Using natural food colours like turmeric for yellow, Leafy veggies for green etc will save our health.
Artificial food dyes can cause hyperactivity, allergic reactions, and behavioral issues in sensitive individuals, especially children. Some dyes have been linked to skin rashes, asthma, and migraines. Long-term exposure may increase the risk of cancer and organ toxicity in animal studies.
Artificial colors do make food look attractive, but it is as harmful as well specially for children who are generally more sensitive. Natural alternatives like beetroot, spinach, turmeric and saffron are better options with health benefits.
Food dyes may make the food more appealing, but they provide little real value—and many pose health dangers. Using natural colors such as turmeric, beetroot, or spinach, not only enhances food color but also promotes safety and health.
Mixed safety record. Synthetic food dyes like Red 40, Yellow 5, and Blue 1 have raised concerns over the years. Some, such as Red No. 3, have already been banned due to cancer risks in animal studies. Others are linked to hyperactivity and allergic reactions in sensitive children .
In response, regulatory agencies like the FDA are phasing out many petroleum-based dyes, pushing companies toward natural alternatives even though these alternatives aren’t risk-free. For example, by 2026–2028, major food brands plan to replace synthetic dyes with plant-based options like beet or turmeric extracts .
