Chili Peppers Don’t Stop Heart Attacks
Why spicy food is delicious, but probably not life-saving

At the end of this period, they found that those who ate more chili peppers had a lower risk of death, in particular death from heart disease, than those who ate very few chilies. In relative terms, chilies appeared to reduce the risk of death by about 25%, which sounds pretty impressive for a seasoning.

Like most epidemiological trials of this kind, the scientists controlled for a range of factors that might be causing both death and chili consumption. It was a large sample, with long-term follow up, and in many ways ticks all the boxes for what…
