Isn't this fascinating?
From a US food website selling in the UK (so they have to list the ingredients because of the FIR law.) US Fanta doesn't actually contain any fruit juice. Mind blown... I can't post the image here nor copy the text but they have to have a warning on it due to the fact it uses Sunset Yellow and Allura Red (both Southampton colours).
UK product listing:
Ingredients (ingredients and allergens may be subject to change, so it is important you check the labels supplied in each delivery).
Carbonated Water, Sugar, Orange Juice from Concentrate (3.7%), Citrus Fruit from Concentrate (1.3%), Acids (Citric Acid, Malic Acid), Vegetable Extracts (Carrot, Pumpkin), Sweeteners (Acesulfame K, Sucralose), Preservative (Potassium Sorbate), Acidity Regulator (Sodium Citrates), Stabiliser (Guar Gum), Natural Orange Flavourings with other Natural Flavourings, Antioxidant (Ascorbic Acid)
Due to the "sugar tax" in the UK, the US version contains two and a half TIMES the amount of calories and nearly three times the sugar. Wowzers.
Not that the UK version is "natural" or "healthy" per se. That guar gum is there to give more of a thick mouthfeel I suspect, not just to "stabilise".
