If you're aware of your health and your dad has diabetes, you'd be watching out for your sugar intake. If you have orange or carrot juice to choose, go with carrot juice, according to iVillage Health.

1 cup of orange juice has 20 grams of sugar while carrot juice has 14 grams only, and that, is still considered high, apparently.
"A single cup of juice is made from numerous pieces of produce. It's inevitably much higher in fructose, which is sugar from fruit and vegetables. Plus, it lacks the fiber that fruit and veggies contain."
—Manuel Villacorta, R.D., national spokesman for the American Dietetic Association

It's best if you go the old-fashioned way- EAT fruits and veggies.
Based on Manuel's statement here...I think this is for the processed-juices that we can find at supermarkets or grocery stores, which I believe isn't nutritious at all. So I think I'll still drink my daily juices, made at home, with fiber and just a bit of brown sugar added, if necessary. =)
