You can add foods you eat on a regular basis, to your list under the "My Food" section.
I am not quite sure what app and what you are saying, but yes, many discussions of health and diet are fairly WASP-o-centric ("WASP" = white angle-Saxon protestant). And while some ethnic foods in this country might not often make a list of healthy foods (what many Americans confuse for Mexican food is anything with a ton of cheese on it), certainly a lot of Indian cuisine is extremely healthy! Lots of vegetarian options, lots of great spices, and the regular use of curcumin (turmeric) which is considered to be a potentially powerful "superfood" against cancer and inflammation.
