Re: Are hot peppers medically dangerous?

I'd still like to know if anyone has any more info on the potential link between peppers and stomach cancer.
It's hard to find a definitive answer on this. Take this blog post for example:
Quote:
Excessive ingestion of hot peppers has been considered to be a risk factor for gastric and hepatic cancers. Chili and more specifically capsaicin consumption has been shown, however, to be protective against stomach cancer (Surh et al. 1998). In Mexico, where people heavily consume peppers, the frequency of gastric cancer is relatively low (Surh et al. 1998). In the United States, moreover, the rate of stomach cancer incidence has been declining for the past twenty years despite increased chili pepper consumption (Surh et al. 1998). Human gastric cancer may be caused by a number of factors: salty, smoked, or pickled foods, cigarette smoking, insufficient fruit and vegetable intake, and Helicobacter pylori. Capsaicin seems to have some inhibitory effects on carcinogenesis induced by chemical carcinogens such as vinyl carbamate (Surh et al. 1998). Treatment with capsaicin before exposure to gaseous chemicals such as sulfur dioxide and nitrogen dioxide has been shown to protect against free radical-induced pulmonary damage in rats (Surh et al. 1998). Capsaicin is also observed to inhibit inflammatory responses related to tumor promotion (Surh et al. 1998).
All those references are to a 1998 article by Young-Joon Surh, Ph.D. In 2002, Dr. Surh wrote an editorial for the Journal of the National Cancer Institute about the latest research on capsaicum: More Than Spice: Capsaicin in Hot Chili Peppers Makes Tumor Cells Commit Suicide. He stated that The role of capsaicin in carcinogenic processes is quite controversial. Although some investigators suspect that capsaicin is a carcinogen, co-carcinogen, or tumor promoter, others have reported that it has chemopreventive and chemotherapeutic effects. After a detailed look at the current state of knowledge of how it affected cells, he concluded...

There appears to be several studies whose results contradict one another.
