I see Nick Jonas rarely drinking soda. Soda is the one what’s causing his diabetes! If you know any other reasons, answer this question and If you know Nick Jonas’ email, email this to him. And also, read this(below). This is actually by Dr. Joseph Mercola:

One can of soda has about 10 teaspoons of sugar, 150 calories, 30 to
55 mg of caffeine, and is loaded with artificial food colors and
sulphites. I can’t think of any good reason to ever have it. The
diet varieties are also problematic as they are filled with harmful
artificial sweeteners like aspartame.

Studies have linked soda to osteoporosis, obesity, tooth decay and
heart disease, yet the average American drinks an estimated 56
gallons of soft drinks each year. Plus, drinking all that sugar will
likely suppress your appetite for healthy foods, which pave the way
for nutrient deficiencies.

Soft drink consumption among children has almost doubled in the
United States over the last decade, which is not surprising
considering that most school hallways are lined with soda-filled
vending machines.

Schools often make marketing deals with leading soft drink companies
such as Coca-Cola from which they receive commissions–based on a
percentage of sales at each school–and sometimes a lump-sum
payment, in exchange for their students’ health. School vending
machines can increase the consumption of sweetened beverages by up
to 50 or more cans of soda per student per year.

If you routinely drink soda–regular or diet–eliminating it from
your diet is one of the simplest and most profound health
improvements you can make.

LOL.

You can’t get a rid of diabetes. They haven’t found a cure yet. =[
