First, the lines between type 1 and type 2 are blurring, in that there are some adults that have gotten type 1 diabetes, which used to be called juvenile diabetes. And some children that get type 2, which used to be called adult onset diabetes. Some type 2 diabetics can control with diet and exercise, some with oral meds some with shots and some still that use all methods. I for instance take oral meds plus a 24 hour insulin called Lantus. I also take a shot of a protein called Byetta, taken just before breakfast and dinner, that reduces my appetite, glucose introduced by my liver and the amount of carbs eaten at during the meal that get converted into glucose.
When looking at labels the amount of carbs is the most important thing to look at. Sugar is just another carb. So look for the total carbs which sugar is a part.
Fat is the second important number to control because a lot of people that are diabetic also have high colesterol.
Soy milk is ok, personally I still like the real Moo juice. About candrel sugar substitute, I have never heard of it, are there carbs in it? The major key to diabetic control is controlling blood glucose levels this is done by restricting the amount of carbs in his diet and exercise.
As with food choices the lower the carbs in the things he drinks the lower his blood glucose levels will be.
I was taught the carb counting method for control. I can't say exactly how I do that because I am not a doctor.
Go with him the next time he sees his doctor, find out how many carbs he is limited to for a snack and for meals and how to count those carbs.
There is a book out there that can be bought on line that may help you when you shop it is called. "The Doctor's Pocket Calorie Fat & carbohydrate counter Plus 80 fast food chains and Resturants"
There may be a version out there that covers your region of the world, if not this one can help you with making the correct shopping choices to help your brother.
Type 1 diabetes is believed to be from an auto-immune response that kills the insulin producing cells in the pancreas.
Type 2 diabetes, on the other hand, is believed to be genetic and a lifestyle consequence. This means that if your uncle has it, you and your brother is more likely to get it. It also means that if you tend to be a couch potato you are more likely to get it. Neither can be gotten from drinking too much Coke or eating too much sugar.
Above all, don't neglect your own health get plenty of exercise. In fact you can help your brother's diabetes by taking walks with him if you live close enough.
I hope this helps.
