In re: Prevalence of diabetes in India compared to Pakistan.

There is a lower prevalence of diabetes in India than in Pakistan. This could have a correlation with excess meat consumption among those Pakistani Muslims who have descended from Hindu castes/groups which were historically vegetarian.

Extensive research on this is necessary. The results of such research could benefit people around the world, not just in Pakistan.

I my case, while I eat meat, poultry & seafood, I tend to do so once or twice a week and when on vacations, on account of the Hindu caste groups of my parents.

Follow your genes, to the extent you find practical and possible.
