Cherry Juice: What Does the Research Say?

Cherries may be small, but they contain an impressive range of naturally occurring compounds that have attracted considerable scientific interest. Whether enjoyed fresh, frozen, dried or as juice, cherries provide vitamins, fibre, antioxidants and plant compounds that contribute to their nutritional value.

In recent years, tart cherry juice in particular has become a popular topic of research, with studies exploring its potential effects on exercise recovery, sleep quality and markers associated with inflammation.

Sweet vs Tart Cherries

You may have noticed different types of cherry juice available, including sweet cherry and tart (sour) cherry varieties.

Both types provide beneficial nutrients, but they differ slightly in their composition. Tart cherries, particularly the Montmorency variety, generally contain higher levels of anthocyanins and other polyphenols compared with sweet cherries.

Sweet cherries are the variety most commonly eaten fresh and remain a nutritious addition to the diet. They provide vitamins, fibre and antioxidants and can be enjoyed on their own, added to fruit salads or incorporated into a variety of recipes.

The Power of Anthocyanins

Anthocyanins are naturally occurring plant compounds responsible for the rich red, purple and blue colours found in cherries, berries, plums and eggplants.

These compounds belong to a group of phytochemicals known as flavonoids and contribute to the antioxidant activity of many fruits and vegetables. The predominant anthocyanins found in cherries are known as cyanidins.

Researchers have investigated anthocyanins for their ability to help protect cells from oxidative stress and support the body's natural antioxidant defences.

Cherry Juice and Inflammation Research

One reason tart cherries have attracted scientific attention is their naturally high concentration of anthocyanins and other polyphenols.

A number of studies have explored the effects of tart cherry juice on markers associated with inflammation and oxidative stress. While results have been promising, further research is needed to better understand the significance of these findings and how they may apply to different populations.

Exercise Recovery and Muscle Function

Tart cherry juice has also been studied in athletes and recreational exercisers.

Some research suggests that consuming tart cherry products before and after strenuous exercise may help support recovery and reduce perceptions of exercise-induced muscle soreness. Researchers believe the antioxidant and polyphenol content of tart cherries may contribute to these effects.

Although the findings are encouraging, study designs and outcomes vary, and additional research continues in this area.

Cherries and Sleep Research

Tart cherries naturally contain small amounts of melatonin, a hormone involved in regulating the body's sleep-wake cycle.

Several studies have investigated whether tart cherry juice may influence sleep quality, sleep duration and sleep efficiency. While some research has reported positive findings, larger and longer-term studies are needed to better understand the role tart cherries may play in supporting healthy sleep patterns.

Cherries and Joint Health Research

Researchers have also explored tart cherry juice in relation to joint health and wellbeing, particularly because oxidative stress and inflammation are involved in many age-related processes.

While some preliminary studies have reported favourable changes in certain biomarkers, more research is required before definitive conclusions can be drawn.

A Nutritious Addition to the Diet

Regardless of whether you choose sweet or tart varieties, cherries can be a nutritious addition to a balanced diet. They provide a range of beneficial nutrients and phytochemicals and are a delicious way to increase fruit intake.

As with many nutrition topics, the overall dietary pattern remains more important than any single food. Including a variety of colourful fruits and vegetables helps provide the broad range of nutrients and plant compounds needed to support general health and wellbeing.
