Juicing ensures that diabetics drink 100 percent pure fruit and vegetable juices without added sugar, which are the only safe juice drinks for those with diabetes, reports the American Diabetes Association. Pure juice drinks offer needed minerals and vitamins. Additionally, juice is a fast-acting carbohydrate to counter hypoglycemia, a condition of low blood sugar that sometimes affects diabetics, states Mayo Clinic.
Although 100 percent fruit juices are healthy, diabetics must monitor their portions, as carbohydrates and calories add up faster in juices than in whole fruits, advises the American Diabetic Association. Diabetics must include the carbohydrates in juices as part of the total carbohydrate count in their meal plans. Alternatives to carbohydrate-rich fruit juices are low-sodium vegetable juices, which are lower in carbohydrates.
Consuming whole fruits rather than fruit juices provides diabetics with more nutrition and helps them better manage their blood sugar, according to Diabetes Forecast magazine. Whole fruits contain significantly more fiber, which slows down digestion and helps diabetics feel more full. If diabetics drink juice, it should be combined with a meal containing fat and protein to slow digestion and cause blood sugar levels to rise more slowly. Diabetics who drink fruit juice to treat hypoglycemia should check blood sugar levels before and after drinking it.
