Don’t they eat a lot of turmeric? I hear it’s a great anti-inflammatory(?) and has a number of benefits.
That they do and it was my first thought too when I read the headline. I started using quite a bit of the spice about 6 months ago when I started buying it in bulk.
On the other hand India has a higher instance of heart disease so who really knows. Could be it simply didn't get into the population before people started being extra aware of contact and generally avoiding germs.
