2. Maintains blood pressure

Cucumber juice has a rich amount of potassium, which helps with the widening of blood vessels. As a result, it helps in relieving the tension of the blood vessels, and thus, regulates blood pressure level. Due to the presence of potassium, cucumber juice is also a good source of electrolytes, which helps in maintaining a healthy balance in body fluids.

3. Lowers blood sugar

Blood Sugar

Cucumber juice contains an ample amount of vitamin K that may be helpful in maintaining blood sugar levels. Vitamin K helps in clotting or coagulation. Blood clotting prevents the loss of blood through wounds, which is crucial for diabetics. Studies conducted by the American Diabetic Association show that it may increase insulin sensitivity as well.

Cucumber juice may be a healthy tonic for diabetes patients as it supplies the required amount of potassium. Low levels of potassium have been linked to an increased risk of diabetes. However, excess potassium is just as bad for the kidneys, therefore, people with diabetes should maintain the required level of potassium.

4. Lowers cholesterol

Cucumber juice consists plant sterols that may help to reduce the low-density lipoprotein (LDL) cholesterol and increase the high-density lipoprotein (HDL) cholesterol. Thus, cucumber improves heart health by minimizing heart attack risks and other related health conditions.

5. May inhibit cancer

Regular consumption of cucumber juice may lower the chances of cancers of the uterus, ovaries, breast, and prostate glands.

6. Maintains bone heath

Calcium and potassium are essential minerals for bone health. Cucumber juice offers a fair amount of these minerals which helps in improving bone structure and bone metabolism. It also induces the production of bone building enzymes.

7. Maintains biochemical functions

Another important mineral that cucumber juice has is magnesium. Magnesium is necessary for normal muscle and nerve function, a steady heart rhythm, strong bones, and good immunity. It is also involved in energy metabolism and protein synthesis.

Cucumber juice may have traces of copper as well, which increases biochemical functions. It is helpful in producing neurotransmitters and healthy red blood cells. It strengthens both connective tissue and immune system.

8. Aids in weight loss

Some amount of dietary fiber may be present in cucumber juice if it’s made with the skin intact and without filtering. As a result, drinking cucumber juice on empty stomach provides a sense of hunger satiation and keeps us feeling full. It also helps with bowel movements and speeds up the metabolism. Thus, cucumber juice for weight loss may help with shedding those extra pounds. Furthermore, it is low in calories and free of saturated fats.

Cucumber juice is enriched with essential nutrients like vitamins K, D, C, and A, as well as folate, calcium, magnesium, and potassium. All these nutrients work together to bring relief from joint conditions such as gout and arthritis pain.

10. Improves eyesight

A good amount of vitamin A in cucumber juice makes it a beneficial drink for eye health. It also enhances the functions of the organs like the heart, lungs, and kidneys. Beta-carotene acts as an antioxidant, thus, protecting cells from free radical damage.

11. Improves skin health

Cucumber juice has vitamin C that plays a vital role in collagen synthesis. Collagen is a protein that builds skin elasticity and reduces the development of fine lines and wrinkles on the skin. Vitamin A is also useful for skin health.

Side Effects of Cucumber and Its Juice

The benefits of cucumber juice come with minimal side effects, and therefore, it should be taken daily for complete wellness. However, as we all know, moderation is the key. These are some of the possible side effects to be mindful of.

  • Excess of cucumbers or their juice can work as a diuretic, leading to loss of fluids in the body. This is because of the cucurbitin present in cucumber seeds.
  • The high water content in cucumbers could put extra pressure on the kidneys if consumed in excess.
  • Some portions of cucumber may taste bitter as they contain cucurbitacins, or tetracyclic triterpenoids, which are toxic. Excess consumption of this bitter portion may be toxic for the body.
  • The vitamin K in cucumber helps in blood clotting, which may interfere with blood thinning medications. So, those who are on blood thinners should consume cucumber with caution and consult their doctor if required.

Now that we know all the benefits of cucumber juice and its side effects, we can conclude that it is a fine choice as a health drink. It is refreshing and harmless to health, even if we consume a small glass every other day. With a good amount of water and other essential nutrients, there is nothing bad cucumber juice can bring to our health, provided we practice moderation. So, enjoy the spring and summer seasons with a glass of refreshingly cool cucumber juice.
