Re: Didn't John Wayne die of Stomach Cancer?

I've heard from somewhere that the reason John Wayne died of stomach cancer was that he had worked many western films in the southwest and because of the nuclear testing in the area had eventually affected him in this way. It'd be interesting to find any studies done on this possible link.

Another possibility is the link between the amount of salt ingested related to fermented soy products:

"It's very important to note that the increased risk of stomach cancer with miso is likely due to the fact that this soy product is high in salt and statistical analysis demonstrated this in the Wu et al. study. A high intake of salt is very strongly linked with increased stomach cancer. Also, the decrease in risk with nonfermented soy products may be due to an accompanying increased intake of fruits and vegetables (well known to decrease stomach cancer risk)."

"looking at the data more closely showed that consumption of fermented and non-fermented soyfoods may be correlated with high salt and fruit and vegetable intake respectively. Salt and fruit and vegetable intake were not adjusted for in these studies and so the apparent effects of soy on stomach cancer risk may be due to these associations. Until studies consider these other dietary factors, the role of soyfoods in the aetiology of stomach cancer remains uncertain."

However, dietary advice in relation to lowering stomach cancer risk is not wholly dependent upon the outcomes of future studies. The findings from this meta-analysis is consistent with current guidelines, i.e. decrease salt intake (which would include fermented soyfoods such as soy paste or miso, which have a high salt content); increase fruit and vegetable consumption; and try replacing some animal protein with vegetable protein (which would include non-fermented soyfoods such as tofu).
