There is some merit to having suspicion on nutrition. The amount of oil consumption is quite high. Every thing is fried or deep fried. You could easily see this in the snacks that are consumed with tea/coffee.

This isn't really accurate. It's is the common conception of Indian food based on what is usually available in the States, but that's usually only Punjabi food, and even for Punjabi food it's the sort of cuisine that you'd cater for a wedding. It's not at all representative of what people eat on a daily basis. It's like going to P.F. Chang's or Tex-mex and assuming that that's what people typically eat in China and Mexico (respectively).
Indian and Bangladeshi cuisines vary quite significantly by region, and in at least some cuisines there's very little oil and/or fried food.
Sure there is. However this article seems to make the point that just even if you eat right and are active, you are predisposed to these problems just by being of South Asian decent. The section of the article "The Indian/South Asian Risk Factor" talks about that.
OK, then why does the same effect seem to exist in Indians living elsewhere, and not among non-Indians in other smoggy places (e.g. China)? The smog factor was already accounted for. There's still something going on here, and several credible genetic/metabolic explanations are being examined. That's science. Presenting obviously-irrelevant facts as explanations is how science gets derailed (and apparenty the local tone police are more than happy to help with that).
