That's probably because most Asian and East Indian restaurant dishes add a lot of hot spices to the Curry which can be tough on the stomach.
Buy Turmeric in it's pure powdered form (most health food stores)and add it to some of your home meals. You'll find that by itself it does not have a spicy taste.
It is one of the most healthy food you can take.
LOL I was raised in a Filipino family we didn’t did use curry but later on as an adult I got into a hobby of cooking dishes from all Asian cultures.
That’s when I found out not all Asian cuisine is alike.
Roasted whole Pig, pancit, lumpia and the like is yu uhm my!
