Good one Hemalatha. I have also found that veering away from the diet I grew up with is not sustainable. However, I have found that as long as I stick to the carb/protein ratios I am fine. My husband grew up primarily eating protein. My body knows how to process and work with carbs and for my husband it's protein. So we both eat what out body knows to process, but we make sure we stick to calorie counts. That I found helps.
This is very interesting. I have learnt a lot about substitutions from my 2 years of being a vegan. It takes a lot of effort to write down non-american recipes, such as indian recipes. I will try it out and see what it tells me.
