I lived in England in the 70's. The only thing open after the pubs closed was Indian restaurants. I loved the spiciest Vindilu (sp) curries. They would create a hostile environment in my colon that I almost died from. I'm not surprised that pathogens can't live there either.
"They would create a hostile environment in my colon that I almost died from."
Yellow curry, particularly at the concentrations used by many Indian restaurants, causes me some digestive discomfort, but red curry does not. Why that is, I really don't know. Thai cooking uses a lot of red curry.
