Eating Spicy Food Linked to a Longer Life

As much I read about this particular study, in the group of the more spicy eaters, there where plenty of rural people and in the other group more urban people. So, this sounds to me, that there are different factors inside the study which are interconnected and the "evidence" could also be linked to some different factors, for example more healthy lifestyle of rural people (particular in China: I assume healthier air). In the article, I read, they even suspected, that more tea consume of the spicy group could also cause the positive effect.

So, every study should be taken with a grain of salt, particularly when the exact circumstances are not told.

Good point. Loads of people die early over here in Bangladesh, and we eat some of the spiciest foods in the world.

...maybe. I saw another article about this yesterday, in which they stated that there were other variables in play that could have impacted the results, including a greater of variety of spices in spicier food. Capsaicin is a possible cause of the results, but not definitive

Only if you don't like spicy food.

China has eight main cuisines related to different areas in China. Some of these cuisines are spicy and some are not.

Obviously a whole lot other things also differ together with the spices in these cuisines. It would be nice if they'd asked if the subjects identified with a specific cuisine/area.

There could also be a wealth relation. The poorer Guandong (Cantonese) kitchen has little less chili than the famously spicy Szechuan kitchen which is from a richer area.
