evidence: New research by the European Food Standards Authority warns that a contaminant found in the palm oil used in Nutella could cause cancer - but Ferrero, the hazelnut and chocolate spread's creator, is doing everything it can to shut down the claims. The study found that the oil's edible form is carcinogenic (meaning it has the potential to cause cancer), and warned that even moderate consumption of the spread represented a risk to children. [...] But Ferrero insist their product is safe, and have launched an advertising campaign in an attempt to reassure customers that Nutella does not increase the risk of getting cancer - instead insisting they use palm oil to increase the product's quality.
