Vitamin C can help beat cancers

Not a very catchy story, is it? Let's spice it up a bit -- "Munch on: Potato chips can help beat cancers":

The mouth-watering chips have long been labelled as a "junk food". Yet, experts have claimed that gorging on a deep-fried potato diet can help people in beating certain cancers.

According to them, chips are rich in vitamin C, which tackles dangerous free radicals associated with cancer growth, and those suffering with the disease can even shrink the size of their tumours by eating wafers, the Daily Star reported.

Why do I get the feeling that this news item has an ulterior motive of persuading people to eat more of a) potatoes or b) junk food? The conspiracy theorist in me leans towards (b) -- potatoes, after all, are proven to be a good source of nutrition (including vitamin C), and there are other, much healthier, sources for vitamin C as well.
