You might want to investigate Dr Vasant Lad's videos (2 in number, IIRC) on Ayurvedic cooking in particular, and the principles, or at least techniques, of (spices and masalas used in) Indian cooking in general. All with a view to improved digestion. He is a senior Ayurvedic doctor and the founder of the Ayurvedic Institute, Albuquerque, New Mexico, USA. There is also a book about this subject (the cooking), by some woman, IIRC, but sorry, cannot remember the name.
