The presence of Red 40 in commercial strawberry lemonade
Many commercial strawberry lemonade products contain the synthetic food dye Red 40, also known as Allura Red AC, to create a bright red or pink color that suggests a strong fruit flavor. However, this color doesn't always mean real strawberries are present; in some cases, the color is artificial, and the flavor comes from other sources. Red 40 can be found in various products like drink powders, sports drinks, and bottled juices. Some brands, such as Country Time and Powerade, have used Red 40 in certain strawberry lemonade versions. To avoid this additive, consumers should always check the ingredient label, as its presence may not be evident from the packaging alone.
What is Red 40?
Red 40 (Allura Red AC or E129) is a synthetic dye made from petroleum, distinct from natural colorings derived from plants, minerals, or insects. It's one of nine color additives certified by the U.S. Food and Drug Administration (FDA) for use in food, drugs, and cosmetics. While the FDA considers it safe within regulated amounts, its safety is debated. In Europe, products with Red 40 must carry a warning about potential adverse effects on children's activity and attention. This has led some manufacturers to use natural alternatives in products sold in Europe compared to the same items in the US.
Potential health concerns associated with Red 40
Despite FDA approval, some studies raise concerns about Red 40, leading some consumers to avoid it. Key concerns include:
- Hyperactivity in children: Research suggests a possible link between synthetic food dyes, including Red 40, and increased hyperactivity, especially in children sensitive to these additives or with ADHD. A 2007 study and a 2021 California assessment noted such associations and potential to worsen neurobehavioral issues in some children.
- Allergic reactions: Though uncommon, Red 40 can cause allergic reactions in some individuals, from mild symptoms like hives to more severe anaphylaxis.
- Inflammation and gut health: A mouse study published in 2023 in Nature Communications indicated that continuous exposure to Red 40 caused gut inflammation and altered the gut microbiome. The long-term effects on humans are still being researched.
- Carcinogenic contaminants: Trace amounts of carcinogens have been found in Red 40 production, prompting concerns about cancer risk. This was a factor in the FDA's decision to phase out Red 3.
How to spot Red 40 on ingredient labels
To identify Red 40 on ingredient labels, look for the following names:
- Red 40
- FD&C Red No. 40
- Red No. 40
- Allura Red AC
- E129 (in European markets)
- CI Food Red 17
Checking labels is the best way to avoid Red 40, as it can appear in unexpected products like cereals and baked goods. For those concerned about consumption, particularly for children, reading ingredient lists is crucial.
Natural alternatives and how to find them
Those who want to avoid synthetic dyes have access to natural alternatives, often derived from fruits and vegetables. These are typically listed on labels, simplifying the search for dye-free products.
- Fruits and Vegetables: Concentrates or extracts from fruits and vegetables like black carrot, elderberry, or purple sweet potato can provide natural red or pink colors. In-N-Out, for example, replaced Red 40 with vegetable juice and beta carotene in their pink lemonade.
- Beetroot: Beetroot extract is commonly used for natural pink and red shades, though it can be sensitive to heat.
- Paprika: Paprika extract can create warmer orange-red colors and is more heat-stable.
A comparison of red colorants
| Feature | Red 40 (Allura Red AC) | Natural Alternatives (e.g., Beetroot) | Carmine (Cochineal extract) |
|---|---|---|---|
| Origin | Synthetic, derived from petroleum | Plant-based, from fruits or vegetables | Insect-based, from crushed cochineal beetles |
| Health Concerns | Linked to hyperactivity in sensitive children, possible allergic reactions and inflammation | Generally considered safer; no known links to ADHD or hyperactivity | Can cause allergic reactions in some people |
| Vegan Status | Vegan (synthetic) but tested on animals | Vegan, plant-based | Not vegan |
| Labeling | Explicitly listed as 'Red 40' or 'FD&C Red No. 40' | Listed by source, e.g., 'Beetroot Extract', 'Vegetable Juice' | Listed as 'carmine' or 'cochineal extract' |
| Color Stability | Excellent heat and light stability | Can be less stable, pH-dependent | Excellent stability |
How to make your own natural strawberry lemonade
Making your own lemonade is a great way to ensure a dye-free and healthy drink, giving you control over all ingredients.
Ingredients:
- 1 cup fresh or frozen strawberries

Conclusion: Making an informed choice
Being aware of artificial dyes like Red 40 helps consumers make informed decisions. Checking ingredient lists on strawberry lemonade products is crucial for identifying brands with natural colorants or choosing to make your own. As demand grows for cleaner ingredients, more companies are offering products with natural alternatives, making healthier options more available. While the discussion about Red 40 continues, consumers can make clear choices about what they consume.
