Living with diabetes involves limiting foods that could raise blood sugar to high levels. Juice can be a part of an overall healthy diet in limited amounts. When choosing a fruit juice, the American Diabetes Association recommends 100 percent fruit juice with no added sugar. 

While most fruits are forbidden for diabetics because of their sugar, pomegranates are recommended. According to research published in American Journal of Clinical Nutrition Oct 2017, Low–glycemic index diets have demonstrated health benefits associated with a reduced risk of developing type 2 diabetes. Results indicates that pomegranate polyphenols, when present in a beverage but not in a supplement, can reduce the postprandial glycemic response of bread, whereas microbial metabolites from pomegranate polyphenols exhibit the potential to further modulate sugar metabolism much later in the postprandial period.

In another study that was conducted in Israel by Dr. Michael Aviram, a medical expert of the Technion Faculty of Medicine reported that diabetes who drank pomegranate juice for three months had a lower risk of atherosclerosis  or hardening of the arteries. In addition, the pomegranate juice appeared to slow the absorption of unhealthy LDL cholesterol LDL cholesterol by immune cells. This is due to  antioxidants found in pomegranate juice may be especially beneficial in reducing these heart-related risks associated with diabetes.
