Tart cherry juice may lessen inflammation, thus reducing pain in women with osteoarthritis, according to changes noted in specific inflammatory serum biomarkers.
This study used a randomized, double blind, placebo-controlled trial design, involving twenty women with inflammatory osteoarthritis, aged between 40 to 70 years. The participants were given 10.5 ounce bottles of tart cherry juice or a placebo cherry drink to consume twice daily for a span of 21 consecutive days. Pain was assessed at the start and the end of the intervention period. At these same junctures, blood samples were collected to monitor the influence of the juice on serum biomarkers of inflammation: C-Reactive Protein, Interleukin-6, Interleukin-10, and Tumor Necrosis Factor-alpha.
The results depicted that the group consuming tart cherry juice experienced a significant reduction in the serum biomarker, C-Reactive Protein, an indication of lowered inflammation. This is suggestive that tart cherry juice could be an efficient way of reducing inflammation, and subsequently, the pain experienced by women suffering from osteoarthritis.

Review Article Anti-Diabetic Anti-Inflammatory Antioxidant
The research primarily studied the health-promoting potential of cherries and blueberries, given their high nutritional density and substantial phenolic compounds. The focus was on their ability to counteract oxidative stress markers and suppress pro-inflammatory responses, which are significant factors in chronic diseases such as diabetes. The researchers analyzed these fruits for their potential incorporation into various products such as pharmaceutical preparations, smart foods, functional beverages, and nutraceuticals.
In the discussion of the results, it was emphasized how cherries and blueberries exhibit significant biological potential. They were not only seen as effective in combatting oxidative stress and inflammation but also as potential immune boosters. The conclusions underscored the fruits' potential role as functional foods and their relevance to the burgeoning popularity of functional beverages, hinting at their promise for inclusion in a variety of health-related products.
Regular dietary intake of olive oil reduces the levels of certain inflammation markers, making it a beneficial alternative dietary fat, especially for managing IL-6.

Systematic Review Anti-Inflammatory CRP IL-6
The methodology of this review involved summarising data from randomized controlled trials to investigate the impact of regular dietary intake of olive oil on three specific inflammatory markers: C-reactive protein, interleukin-6, and tumor necrosis factor-alpha. These studies looked at how regular usage of olive oil as part of the diet can affect these markers and provide benefits to individuals who implement it in their dietary routine. The trials focused primarily on the Mediterranean diet, which is known for its high usage of olive oil as a main fat source.
The results indicate that olive oil, when consumed on a consistent basis, can reduce the levels of inflammatory markers. It has been observed to be particularly effective in managing levels of interleukin-6. The results obtained from the review of these trials suggest that olive oil can indeed be a beneficial supplement to diet with potential impacts on managing inflammation and related diseases. They hint at potential effectiveness of olive oil as a nutritious factor in mitigating the adverse impacts of a diet high in unhealthy fats, by providing it as a healthier alternative.
Green tea and its compounds, especially catechins, may potentially prevent and treat osteoarthritis due to their potent antioxidant and anti-inflammatory properties.
2020 Longhua Chinese Medicine The possible role of green tea on osteoarthritis: a narrative report Barbalho SM, Goulart RA, Buglio DS, Araujo AC, Guiguer EL
Review Article Anti-Inflammatory Antioxidant Green Tea
The researchers performed an extensive review exploring the potential impact of green tea and its bioactive compounds, chiefly catechins, on osteoarthritis management. Their focus was on the anti-inflammatory and antioxidant abilities of these compounds. Based on the review, such compounds can quell inflammation by blocking various signaling pathways interconnected with inflammatory processes. Specifically, they have the potential to suppress the expression of several cytokines and enzymes related to inflammation.
In addition, green tea was noted for its property to neutralize free radicals, thus averting the formation of harmful reactive oxygen species and countering oxidative stress. While many conventional, non-surgical osteoarthritis therapies can lead to numerous adverse effects, the current review suggests that green tea could serve as a safer alternative. It may be a promising direction in the prevention and management of this chronic, painful, and inflammatory condition, which touches a significant number of people globally.
Daily consumption of tart cherry juice may enhance cognitive abilities in older adults, likely due to reduction of hypertension, inflammation, and oxidative stress.
2019 Food & Function Effect of Montmorency tart cherry juice on cognitive performance in older adults: a randomized controlled trial Chai SC, Jerusik J, Davis K, Wright RS, Zhang Z
Randomised Controlled Trial Anti-Ageing Anti-Inflammatory Antioxidant
In this randomized controlled trial, 37 adults aged between 65 and 80 years with normal cognitive function were assigned to consume two cups of Montmorency tart cherry juice daily for a duration of 12 weeks. Participants' subjective memory and objective cognitive performance were evaluated at the starting point and after the 12-week juice supplementation using a validated memory questionnaire and a standard assortment of tests designed for cognitive assessment. Factors such as daily caloric intake and physical activity levels were also monitored during the study.
After the 12-week intervention, participants who consumed tart cherry juice showed an improvement in their contentment with memory scores, demonstrated decreased scores of movement time, and performed better on a task of paired associates learning when compared to the control group. Notably, the results revealed that the tart cherry juice group demonstrated improvements on measures of visual sustained attention and spatial working memory relative to their own baseline values. These findings suggest that the potential benefits of tart cherry juice to cognitive abilities might be attributed to the juice's antioxidant and anti-inflammatory properties, and its capacity to reduce blood pressure.
Powdered tart cherry supplementation surrounding endurance exercise can decrease muscle damage markers, inflammation, oxidative stress and muscle soreness, while improving performance.
2016 Journal of the International Society of Sports Nutrition Effects of powdered Montmorency tart cherry supplementation on acute endurance exercise performance in aerobically trained individuals Levers K, Dalton R, Galvan E, O’Connor A, Goodenough C, Simbo S, et al.
Clinical Study Anti-Inflammatory Cherry Exercise Performance
In this study, 27 endurance-trained runners were matched based on their race pace, age, body mass, and fat-free mass. The runners were split into two groups in a double-blind manner: a placebo group given capsules containing 480 mg of rice flour and a tart cherries group given CherryPURE® capsules. These were ingested daily for 10 days, including on the day of the half-marathon and up to 48 hours post-race.
The results showed that runners given tart cherry supplementation completed their half-marathon faster (by 13%) than those given a placebo. Moreover, the tart cherry group had less muscle damage markers over time, a steady increase in antioxidant activity during recovery, 47% lower inflammatory markers, and a 34% lower pre-run soreness in the medial quadriceps compared to the placebo group. These results demonstrate the beneficial effects of tart cherry supplementation on performance and recovery in aerobically trained individuals.
