Thank you much for the detailed reply . It would have taken from your own time for sure 🙏
I am going through your suggestions and advice carefully . Meanwhile I am trying the low FODMAP diet from Monash University , with a modicum of improvement in my diet status .
Yet not all food allowed by this diet agrees with me .
For eg , Sweet potato , lotus seeds, coconut , ivy gourd , egg , almond milk , tofu , soya milk etc are all allowed by FODMAP diet , but are a complete no-no for me .
I am normally an eggetarian and yet so far what agrees with me is

Carrots
Spinach
French beans
Cucumber
2 slices normal tomato
30 gms red cooked pumpkin
Raw banana
Small amount of potato
Ripe banana
Dragonfruit
Blueberries
Tahini sauce 2-3 tsp
Peanut butter 2 tsp
Sesame oil unrestricted
Sesame seeds 2 tsp
Rice

That is it so far .
I must say that I tried two pieces of chicken , though culturally is an enormous challenge for me , and found it seemed to agree with me .

Do not know if I can accept eating chicken though …… have to work that through in my head first . …..
Will keep posting here as I progress .
Thank you to all the kind members , who posted here for me . Your concern and inputs are very valuable to me .
PS - I am a researcher in public health and quickly realized that most dietitians will give only general advice and not pointed to my unique problem ….. it is only information locations like this group that will hopefully help me to climb out of this place .
