Hot dog menace ?

Dear Reader,

I have seen a newspaper report that some Swedish workers (S.C. Larsson and A. Wolk) have shown that eating hot dogs may be bad for your health. In their meta study it has been shown that eating hot dogs increases the risk of a rare form of cancer, while the cancer is rare and the increased threat posed by eating hot dogs is small it does again show that nitrites which are associated with N-nitrosoamines are carcinogenic. If I get the time I will explain a little more about this class of compound. Examples of these compounds are found in a range of places including in the urine of smokers.

I will explain what a meta study is, it is a study where no new experimental work is done. What happens is that it takes existing data from normal studies and then combines them to allow us to see the trends more clearly. The use of a meta study reduces the effect of random errors and it allows us to reduce the statistical uncertainty in the results.
