Worst Food Additives for Children

Children consume more food relative to body weight than adults, their detoxification systems are still developing, and their diets are disproportionately high in processed foods. Here is what the regulatory data says about the additives most prevalent in products marketed to children.

What to Watch For

Body weight scaling

ADIs (Acceptable Daily Intakes) are set in mg/kg body weight. A 25 kg (55 lb) child eating the same portion size as a 75 kg adult receives three times the per-kg dose. Children eating multiple products containing the same additive can cumulatively exceed the ADI on a single day.

Product targeting

Brightly colored products — cereals, candy, fruit snacks, sports drinks, flavored yogurts — are disproportionately marketed to children and disproportionately contain artificial dyes and preservatives. The visual appeal of synthetic color is a deliberate marketing strategy.

The Southampton Six

A 2007 landmark study published in The Lancet (McCann et al.) found that a combination of six food dyes plus sodium benzoate increased hyperactivity in 3-year-old and 8/9-year-old children. The EU responded with mandatory warning labels. The FDA reviewed the same data and concluded it did not demonstrate a causal link — but in 2025 initiated a phased ban on synthetic dyes.

The Dyes to Avoid

FD&C artificial dyes — common in children's cereals, candy, and beverages.

FD&C Red No. 3, Aluminum Lake is a synthetic colorant that was delisted from FDA approval in 2024. It was previously used in food and cosmetics to provide red coloring, though its exact mechanism of action in modern formulations remains unclear.

FDA Dye Phase-Out (2025)

In early 2025, the FDA announced a plan to phase out all remaining petroleum-based synthetic dyes from the US food supply. Red Dye No. 3 (erythrosine) was revoked in January 2025 with a 2027–2028 compliance deadline. Additional dye revocations are expected. This does not constitute an immediate ban — products with these dyes remain on shelves until the compliance deadlines pass.

Preservatives & Other Additives of Concern

Beyond dyes — preservatives and sweeteners with pediatric-specific concerns.

High Fructose Corn Syrup (HFCS) is a sweetener derived from corn starch through enzymatic processing, containing approximately 55% fructose and 42% glucose. It is widely used in beverages, baked goods, and processed foods as a cost-effective alternative to sucrose.

Better Alternatives

Instead of

FD&C dyes (Red 40, Yellow 5/6, Blue 1)

Look for

Beet juice, turmeric, paprika extract, annatto, spirulina

EU-compliant brands already use these in reformulated products sold in Europe.

Instead of

Sodium benzoate

Look for

Rosemary extract, vitamin E (tocopherols), ascorbic acid

Common in preserved fruit drinks. Vitamin C-preserved juices are widely available.

Instead of

BHA / BHT

Look for

Mixed tocopherols (vitamin E), rosemary extract

Many major cereal brands have removed BHT from their formulations in response to consumer pressure.

Instead of

Sodium nitrite in deli meats

Look for

Celery powder (contains natural nitrates), uncured meats

"Uncured" labeling means no added sodium nitrite. Note: celery-cured products still contain nitrates derived from celery.

EU Warning Labels — What They Say

Since 2010, EU Regulation (EC) No 1333/2008 requires all foods containing any of the Southampton Six dyes to carry the following mandatory warning on the label:

"May have an adverse effect on activity and attention in children."

This warning applies to: Sunset Yellow (E110 / Yellow 6), Quinoline Yellow (E104), Carmoisine (E122), Allura Red (E129 / Red 40), Tartrazine (E102 / Yellow 5), and Ponceau 4R (E124). The FDA declined to require similar labeling following a 2011 Food Advisory Committee review, though that decision is under re-evaluation as part of the broader dye phase-out process.
