Diabetes is a common problem among people. The most common symptom is persistently high blood sugar levels. People with diabetes should consume foods with a low glycemic index and low carb density.

The glycemic index is a food rating system based on carbohydrates in foods. Your body breaks down the carbohydrates and helps them dissolve into the body’s blood sugar level. Therefore, it results in high blood sugar levels in the human body.

There are many foods known to control diabetes, one of which is cucumber. It belongs to the Cucurbitaceae family and is known for its digestive properties.

Cucumber is a non-starchy vegetable, making it harmless for people with diabetes. A study suggests that adding non-starchy vegetables to the diet effectively controls type 2 diabetes. If you have diabetes, you can eat cucumber as much as possible as it is low in carbohydrates. Low carb diet improves blood sugar and manages diabetes effectively.

Benefits Of Adding Cucumber To Your Diabetes Diet

Rich in Antioxidants

Cucumbers are rich in vitamin C, Vitamin E, and Flavonoids. It makes it an antioxidant to prevent an oxidative reaction in your body. Your body’s cells release large amounts of electrons in an oxidation reaction. A study shows that the antioxidants present in vitamin C help reduce the complications of diabetes. Whereas vitamin E helps improve glycemic control in people with diabetes.

Extremely Hydrating

Cucumbers contain 95% water, which makes them highly hydrating. Water is responsible for the emission of harmful waste materials, transport of nutrients and thermal regulation. Therefore, consuming cucumbers can help you meet most of your fluid requirements. 

Studies show that people with diabetes should drink plenty of fluids because they are at increased risk of dehydration due to polyurea in them. In addition, since high blood sugar levels reduce hydration, it is essential to replenish the necessary fluids in the body.

Regulate Bowel Movements

A study shows that people with diabetes are more likely to suffer from the problem of constipation. Diabetes damages the nerves of the intestines, causing issues with the movement of food in the stomach. Therefore, it is necessary to have regular bowel movements to cure it.

Cucumbers contain a moderate quantity of dietary fibre, which helps cure chronic constipation. The antioxidant properties of this vegetable helps in detoxifying your body. Fibre binds with faecal matter in the human body to increase the size and density of stools. Thus, fibre cleans the intestine and regulates bowel movements to prevent constipation.

Rich in Fibre

Fibre is suitable for a person with diabetes or people showing symptoms of diabetes. Since fibre regulates blood sugar levels and helps maintain good health, people with diabetes should get a good amount of fibre.

Cucumber contains fibre and sufficient amounts of water as constituents of its nutritional composition. They are also not energy-dense and contain minimal calories concerning their mass. According to a study, foods with high fibre help in managing diabetes. 

Other Miscellaneous Benefits of Cucumber for Diabetes

According to various studies, triterpenes, which reduce blood sugar levels, can halt the formation of enzymes required to develop insulin resistance. They also help in the stabilisation of plasma glucose levels. Triterpenes are substances that are known to restore the imbalance in glucose metabolism. It also aids in curing diabetic disorders such as neuropathy, retinopathy, and nephropathy. Cucumbers also have a very low glycemic index and provide nutrition without too many calories. Therefore, this fruit proves to be a healthy and easy way to maintain nutrition and avoid sugars, especially for people with diabetes.

If you consume cucumber in excess, poor digestion, allergies or blood clotting problems may occur. In addition, consuming excessive cucumber slows down the digestion process and can lead to indigestion.

Excess to Vitamin K is Harmful

According to a recent study, vitamin K in cucumbers has anti-hemorrhagic properties. However, it causes blood clotting in the brain and other bone and vascular diseases if taken in massive amounts.
