Sowbagyavathy VR,
Wheat and rice are easy to grow. Packed with starch and carb. Since it's quite filling, it became the staple diet. Plus, they are easy to store. But they are inlammatory. Anything inflammatory increses blood pressure, reduce blood flow, increses workload on lungs and heart. Spinaches, green leafy vegtable, fruit and vegetables don't do any of these. At one stage Padma was advocating even against dairy products when she was going on a 'liver cleansing diet'. I can't give up my youghurt ( curd); that's were we differed and I did not take part in that 'liver cleansing diet'. I will go for this 'empower Mitocondria diet' since it's much more balanced and I will have yoghurt ( no cheese, no butter though).
I don't know who rice and wheat are meant for.
Cheers!
