Many gujurati Indians suffer from Diabetes in the UK and the west.
Many still eat a mainly familiar diet its the portions and lack of exercise it seems
Another race/nation of people who have changed dramtically are somanlis who i can remeber 10 years ago you would recogonise in the most due to their thin bodies and facial features. Now many have bloated out. I would think that Diabetes would have risen greatly also in their group.
Lets face it many Phills have a diet which has tremdous amounts of fat, sugar and salt used in it.
