Without a doubt go for 'brown everytime'. Remember 'brown is best!' This is also applicable to bread and rice etc.
Basically what happens is that the white rice/bread/pasta etc are full of calories while being devoid of nutritional values and fibre. Such products contain sweetners, preservatives and other unhealthy additives.
The are highly refined and processed which causes them to lose most of their nutritional value and fibre. Thanks to this processing and additives unfortunately they become temptingly tasty! However they can create dramatic surges in insulin levels which may result in overworking your pancreas, storage of fat, diabetes, heart disease, overweight and even obesity problems. It is more important than we realise to choose brown over white.
I hope that helps.
