String bean juice and other green juice is often seen as a healthy way to get extra vegetable servings into your diet. However, when vegetables are juiced they are stripped of fiber, which is an integral part of the diet for people with diabetes.


While string beans are full of nutrients that are beneficial for people with diabetes, juicing them removes essential fiber that helps control blood sugar levels. Consuming them in their whole form is the healthier choice.

Type 2 diabetes, also known as diabetes mellitus, is the most common type of diabetes, according to the American Diabetes Association (ADA). This condition can often be controlled by adjusting your diet to maintain healthy blood sugar levels and through exercise. Still, some people may need medication or insulin to stay healthy. The ADA says that a healthy diet is a significant component of managing type 2 diabetes.

String Beans for Diabetes

The benefits of string beans for diabetes include a high amount of various nutrients, such as vitamin C, vitamin A, folate and vitamin K. These nutrients are essential for everyone, but vitamin A, in particular, has been linked to diabetes.

A December 2014 study conducted on mice published in the Journal of Biological Chemistry concludes that vitamin A is essential for the maintenance of pancreatic cell function in adults. This indicates that vitamin A deficiency may be a culprit for type 2 diabetes.

Vitamin A assists beta cells in the pancreas to produce the hormone insulin, which helps to regulate blood sugar. A lack of vitamin A can cause the death of beta cells and reduce the production of insulin. A reduction in insulin production will interfere with the body's ability to metabolize sugars that come from the food you eat. Since this study was conducted on mice, further research is necessary.

A March 2015 article published in Endocrinology Metabolic and Immune Disorders Drug Targets says that various vitamins play a significant role in the risk of diabetes mellitus, as well as its progression and complications. The researchers recommend the best course of action would be to obtain these vitamins through the diet and not to supplement.

In other words, eating vegetables like string beans for diabetes is your best bet in obtaining the correct amount of nutrition. The vitamins that are mentioned in the study include vitamins A, C, E and B group vitamins, including folate, which are often found to be decreased in people with diabetes. String bean juice and whole string beans contain many of these essential nutrients, as mentioned, making this green vegetable ideal for those with diabetes.

String Bean Juice and Diabetes

Although eating string beans for diabetes may be beneficial, that doesn't necessarily mean that string bean juice is the best way to consume them. One of the most important dietary factors for people with diabetes is getting enough fiber.

The American Diabetes Association recommends eating between 25 and 30 grams of fiber each day, noting that most Americans do not meet these recommendations. Fiber helps lower your blood sugar, which is an essential factor in controlling type 2 diabetes.

Harvard Health Publishing notes that when you are juicing vegetables, you remove the skin, much of the nutrients and insoluble fiber, which reduces the health benefits that whole vegetables contain. Too much juice, including string bean juice, could cause weight gain for people with diabetes since the calories and sugars are concentrated and the fiber is lacking.

The optimal way for a person with type 2 diabetes to consume green beans is to eat them in their whole form as part of a healthy diet.
