Grape Juice: Uses, Benefits, Side Effects and More!

By Dr Ashok Pal +2 more

Introduction:  

 Many varieties of grapes are grown in the world. However, the European species (Vitis vinifera) and the American species (Vitis labrusca) are mainly utilized for making grape juice and wine. They contain a high amount of bioactive compounds that may make grapes more than just a delicious fruit for juices and wine! The nature of the grape, planting and storage conditions along with the industrial process used for the production of the grape juice may interfere with its potential health- related properties.1

Grape juice has a unique colour, flavour and aroma. It is a non-fermented juice and can be conserved when subjected to treatment. When fresh grape juice undergoes alcoholic fermentation, we obtain one of the world’s loved drinks – wine. The bioactive compounds and properties of grape juice are slightly different from that of wine. Let’s read and find out more about the properties, potential uses and side effects of grape juice.1

Grapes, which are rich in antioxidants, may aid in the battle against free radicals, which are chemicals that may harm cells and perhaps cause cancer. To help lower the risk of cancer, antioxidants minimise what is known as oxidative stress. Resveratrol, an antioxidant found in grapes, may prevent cancer by lowering inflammation and preventing the development of cancer cells. In addition to these antioxidants, grapes also contain catechins, quercetin, and anthocyanins, which together may be particularly effective against cancer. Hence, I strongly recommend the daily consumption of grape juice in the right amount.

Potential Uses of Grape Juice for Overall Health: 

Grape juice might have potential health benefits. However, right now, there is no clear evidence that states the effects of grape juice on our health. So, according to the currently available studies, the following are the potential uses of grape juice. 

1. Potential uses of grape juice for oxidative stress 

A recent study conducted by Cheng et al. in the year 2017 showed that grape juice might have the potential to help reduce oxidative stress. It was observed that grape juice might exhibit this effect due to the antioxidant activity it might possess. Grape juice might help improve the enzymatic activity of certain enzymes (SOD, GP, etc.) which might possibly help reduce the oxidative stress in the body. However, there is a need for more research to prove such effects of grape juice on human health.3 

2. Potential uses of grape juice for cholesterol 

In a study conducted on animals in 2018, it was seen that grape juice might have the potential to help lower the level of lipids in our blood. Other studies reached similar conclusions. This may be due to the presence of bioactive compounds in grape juice. However, there is a need for more studies on humans to understand the effects of grape juice on lipids (fats) in the body. The diagnosis and treatment of cholesterol should be made by a doctor. So, make sure that you consult a doctor.3 

3. Potential uses of grape juice for the liver 

Several studies have shown that grape juice might help the liver. This effect might be due to its possible lipid-lowering effect. This potential property may be attributed to the bioactive compounds present in grape juice. However, more studies are required to prove its effects on humans. Conditions of the liver can be serious so ensure that you visit a doctor if you suspect an underlying liver condition.3 

4. Potential uses of grape juice for inflammation 

Seymour and Bolling, in their study conducted on mice in 2016, found that grape juice might possesses anti-inflammatory property. It is hypothesised that the compounds in grape juice might interfere with the pathways of inflammation and might help reduce inflammation. However, there is a need for more research to prove such claims.3  

5. Potential uses of grape juice for diseases of the nerves 

As per recent studies conducted by Hakova et al. 2020; Cicero, Ruscica and Banach 2019; Rameshrad et al 2019, and Sun et al.2008, it seems that grape juice has a bioactive compound called resveratrol that might have the potential to protect against diseases of the nerves. Researchers think that grape juice might help with Alzheimer’s, Parkinson’s and other chronic degenerative diseases of the nerves. However, a lot of research has to be conducted to back up such claims.1  

Though there are studies that show the potential uses of grape juice in various conditions, these are insufficient, and there is need for further studies to establish the true extent of the benefits of grape juice on human health.  

Because it contains a lot of vitamin C, grape juice may support your immune system’s defence against viral and bacterial illnesses, including yeast infections. From my knowledge, if we have a strong immune system, our body is better able to fight against and avoid any sudden, brief illness.
