Spicy food in India

I was told why that people have been eating spicy food for centuries in India. I will let you decide if it sounds reasonable. I could see where it could be an explanation.

Most of the people in India are so poor that most of their lives they only eat maybe one meal a day. So if they eat spicy food, it makes them very thirsty and they drink a lot of water to quench their thirst and the water fills their stomachs.

Now only eating one meal a day, I can actually see that as a fact even today in India. Looks like you could drinks water without having to eat the food so spicy hot.
