Via Drudge, "Food colourings linked to hyperactivity, asthma, and even cancer, have been detected in chicken tikka massala, one of the UK�s favourite dishes..."

[One of the dyes used] can cause blurred vision and purple skin patches and is particularly hazardous for asthmatics and anyone allergic to aspirin...

[Another can cause] chromosome damage and kidney tumours as well as abdominal pain, hives, nausea and vomiting...

Mostly just posted for my clever post title. I just don't know what to say, besides "an investigation, limited to chicken tikka massala" is not a line I ever thought I'd see in a news article anywhere. Imagine what the tandoori red color is doing to your insides. Post your favorite completely unnaturally colored foods in the comments. :)
