Hidden sources: Beetroot red: Not just for salads! This vibrant vegetable can be concentrated and processed to create a natural red coloring often used in candy, yogurt, and sauces.

Turmeric: This golden spice isn't just for curry. Its curcuminoids provide a bright yellow hue used in cheeses, crackers, and even some ice creams.

Carmine: Derived from cochineal insects, this crimson colorant was prized by Aztecs and is still found in some maraschino cherries, juices, and cosmetics. Beyond aesthetics
Color psychology: Food scientists use color strategically. Studies show cool blue tones can evoke freshness and calming effects, while warm reds trigger excitement and appetite.

Standardization: Consistent colors can reassure consumers. Think bright orange cheese puffs or neon-green Gatorade – these hues become associated with the expected flavor and brand recognition.

Identification: Colors can signal specific dietary needs. Yellow M&Ms might signify peanut-free, while a blue frosting dot on cupcakes could mark the gluten-free ones.

Health considerations
Natural vs. artificial: While natural colorings are generally considered safe, some artificial dyes like Yellow 5 and Red 40 have been linked to hyperactivity in children. Concerns about possible contaminants also exist.

Labeling loopholes: Some processed foods use "natural flavors" to avoid listing individual colorings derived from plants or insects. Check ingredient lists carefully if you have specific sensitivities.

Alternative options: Opting for naturally colorful fruits and vegetables in your diet eliminates the need for added colorings and provides additional nutrients.

Unexpected uses:
Medical diagnostics: Specific dyes can highlight certain tissues or blood flow during medical imaging, aiding in diagnoses.

Textile industry: Food colorings can also be used to dye fabrics, especially in temporary applications like hair color or temporary tattoos.

Remember Moderation is key. While occasional enjoyment of colorful treats is fine, a diet rich in whole, unprocessed foods provides natural color and essential nutrients.

Be an informed consumer. Read ingredient lists and do your research if you have concerns about specific colorings.
