5 positive benefits of spinach juice

This is an automatically translated article.

1. Fresh Spinach Juice Rich in Antioxidants

Drinking spinach juice is a very good way to replenish antioxidants. Antioxidants neutralize unstable chemical molecules (free radicals), so they help protect you from oxidative stress and chronic disease.
Spinach is an exceptional source of nutrients and contains high amounts of antioxidants such as lutein, beta carotene, coumaric acid, violaxanthin, as well as ferulic acid. Based on a small, 16-day study in 8 people participants, drinking 240ml of spinach juice per day helped prevent oxidative damage to DNA. Animal studies have also shown similar findings linking spinach to inhibitions of oxidative stress.

2. Spinach juice can help improve eyesight

Spinach juice is rich in lutein and zeaxanthin, two antioxidants essential for the maintenance of vision. Some studies suggest that these substances help protect against age-related macular degeneration, a common disease that can cause permanent blindness.
A review of 6 studies found that a high intake of zeaxanthin and lutein reduces the risk of cataracts. What's more, spinach is rich in vitamin A, a very important vitamin for the eyes. Vitamin A deficiency causes dry eyes and poor night vision.
Although the amount of nutrients will depend on the amount of water along with other ingredients you add. 120 grams of spinach usually squeezes 240ml of juice. This amount of juice provides nearly 63% of the vitamin A you need daily.

3. May help reduce cancer cell growth

Although more human studies are needed, some studies suggest that certain amounts of spinach juice may help antagonize cancer cell growth. In a 2-week study in rats, spinach helped reduce the size of colon cancer tumors by 56%.
Another mouse study also showed that MGDG, a substance found in spinach, enhances the effectiveness of radiation therapy to eliminate pancreatic cancer cells.
What's more, human studies indicate that a high intake of leafy greens reduces the risk of lung, prostate, breast, and colon cancers. Either way, the studies above focused on the wide variety of greens consumed, not just spinach juice. Therefore, more research is needed.

4. May Help Lower Blood Pressure

Spinach juice is rich in natural nitrates, a substance that helps dilate blood vessels. Thus, this lowers blood pressure and improves circulation. A 7-day study in 27 people found that eating spinach soup daily reduced blood pressure and arterial stiffness, when compared with a group of people who did not.
In one small study, a group of 30 people who ate nitrate-rich spinach showed reduced systolic blood pressure and improved levels of nitric oxide.
A 240ml glass of spinach juice also contains about 14% of the daily requirement for potassium - a mineral that is involved in regulating blood pressure by controlling the amount of sodium excreted in the urine.

5. May help improve hair and skin condition

Spinach juice is a rich source of vitamin A, reaching nearly 63% of the recommended daily intake per 1 cup 240ml. This vitamin helps regulate skin cell production and the production of mucus that protects the body from infections.
One cup containing 240ml of spinach juice also contains about 38% of the recommended daily intake of vitamin C. Water-soluble vitamin C is important for health and is also an antioxidant.
Studies show that vitamin C protects the skin from oxidative stress, inflammation, and skin damage that promote signs of aging. Vitamin C helps synthesize collagen, the connective tissue protein that promotes wound healing and skin elasticity. What's more, vitamin C increases iron absorption and even helps prevent hair loss caused by iron deficiency.

6. Potential side effects

While spinach juice has many benefits, there are some limitations to this vegetable for people to consider.
For starters, most research has focused on the spinach itself, not the juices from it. Therefore, more studies on spinach juice are needed. Furthermore, juicing removes most of the useful fiber from the spinach.
Studies show that fiber improves blood sugar regulation, weight loss, blood pressure and cholesterol levels. Fiber also helps protect against several digestive disorders, including hemorrhoids, constipation, reflux, and appendicitis. Spinach is also rich in vitamin K, which in large amounts interferes with anticoagulants such as warfarin. If you are taking anticoagulants, talk to your healthcare professional before adding spinach to your daily diet. It's important to read labels carefully if buying juice from the store, as many may contain added sugar.
Finally, keep in mind that spinach juice should not be used as a meal replacement, as it lacks many of the nutrients needed for a balanced diet. Rather, you should drink it as a way to support a healthy diet, enjoying this leafy green alongside a variety of other fruits and vegetables.
Spinach juice is rich in antioxidants and other beneficial substances that help protect eyesight, lower blood pressure and improve hair and skin condition. However, it is low in fiber and is not suitable as a meal replacement, as it lacks essential nutrients such as protein and healthy fats.
If you drink spinach juice, make sure you use it alongside other nutrient-rich foods as part of a nutritionally balanced meal.
