I have andhra blood. My outer family eats medium spicy stuff. we eat lot of vegetables(we're vegetarians). Average life span about 75 years. There are parts of Andhra Pradesh where they eat too much spicy food. The life span in such areas is less than 65 years. I'm assuming that the article is not referring to this spice level. They're probably suggesting to the average Indian spice levels (which is higher compared to the rest of the world -- especially European and American).
