Gout
Published in Charles Theisler, Adjuvant Medical Care, 2023
Cherry Juice: In a 1950 study, 12 patients with gout ingested one-half pound of cherries per day. In all 12 cases, serum uric acid levels fell to normal and no further attacks of gout occurred. Cherry juice appeared to be as effective as whole cherries.12 It is not known how cherry juice works or what the active ingredient is. Cherries or cherry extract reduced the risk of gout attacks by 35%–40% and when combined with allopurinol, risks were reduced by 75%.13
Use of Supplements in Athletes with an Impairment

Another commonly reported effect was gastrointestinal problems. Flueck et al. (2014) reported 5 out of 9 athletes complained about gastrointestinal symptoms such as diarrhoea after sodium citrate ingestion. Anecdotal evidence suggests tart cherry juice may also have a laxative effect, especially in athletes with a SCI, and the documented impact of dietary nitrate supplements (i.e. beetroot juice) on reducing blood pressure (Burke and Cato 2015) could cause adverse effects in athletes whose blood pressure regulation is disrupted, such as athletes with quadriplegia. Graham-Paulson et al. (2016b) reported adverse effects such as increased spasticity and nausea in 5 of 12 wheelchair rugby players after the ingestion of 4 mg/kg caffeine. Since a high proportion of wheelchair athletes suffer from gastrointestinal complications as a consequence of their impairment (Fynne et al. 2012; Krogh et al. 2000), it seems obvious that this population is more prone to adverse effects of this type. A reduction of the dosage (e.g. related to mg/kg muscle mass instead of mg/kg body mass) or a change in the timing might help to solve these problems. These assumptions are supported by results of two studies in wheelchair athletes. In athletes with quadriplegia, higher plasma caffeine concentrations were reached after the same relative (mg/kg) caffeine dose was ingested compared to able-bodied athletes or those with paraplegia (Flueck et al. 2015). Another investigation showed, at least in some cases, longer times to peak plasma caffeine after ingestion in wheelchair rugby athletes compared to able-bodied athletes (Graham-Paulson et al. 2017). Additionally, the fitness level of an athlete might impact supplement effectiveness (Perret and Flueck 2016), an assumption supported by two creatine monohydrate studies. An ergogenic effect in patients with a SCI was found after creatine monohydrate ingestion (Jacobs et al. 2002), whereas no benefits were found in wheelchair racing athletes (Perret et al. 2006). At present, it seems that at least in Paralympic sport, individual adaptations in terms of timing, dosage and potential risks and side effects is evident.
A role for flavonoids in the prevention and/or treatment of cognitive dysfunction, learning, and memory deficits: a review of preclinical and clinical studies

Although a growing evidence has been gathered and confirmed an association between flavonoid consumption and cognitive benefits, some studies found no or slight correlations. In a pilot study by Caldwell and colleagues, 1-week anthocyanin-rich cherry juice effects were evaluated in three groups including 6 young healthy adults aged from 18 to 35 years, 2 older adults aged 55 and above years, and 5 demented older adults. At baseline and 6 h after consumption, 4 cognitive tasks such as RAVLT, a task-switching test, pattern and letter comparison tasks were used. In young healthy and dementia groups, no significant differences were observed. In older adult group, except for a task-switching test, no significant differences were found followed by 300 ml cherry juice consumption. They concluded that anthocyanin-rich cherry juice intake did not improve acute cognitive impairments. However, they supposed that this dose and timing cannot be effective, and they recommended further research to find effective dose respond and time [92].

In fact, recovery strategies such as cold water immersion, electro stimulation and massage, have been proposed to regain performance faster and prevent injury for soccer players participating in multi-match per week (8). Moreover, nutritional strategies such as tart cherry juice and pomegranate juice have been proposed to attenuate the symptoms of muscle damage (force loss, soreness.), and consequently they become a popular recovery strategies for athlets and sport scientists (9, 10). However, the use of nutrition interventions through real soccer match condition is not well studied. Some intervention such as beta-alanine (11), creatine (12), omega-3 fatty acids (13), Bovine colostrum (14) are examined to determine their effect to increase performance or to limit muscle damage. However, the results of these studies are unclear about the ability of supplements to enhance recovery (15).
Effect of New Zealand Blackcurrant on Blood Pressure, Cognitive Function and Functional Performance in Older Adults

Recent studies have shown cherry juice to decrease resting systolic and diastolic blood pressure in young and old adults, old adults with mild-to-moderate dementia, middle-aged adults and young men with pre-hypertension.26–29 Interestingly, the results from these studies both match the methodology within this study such that measurement of blood pressure was taken 2-hours following intake. What is more, it potentially indicates that changes in blood pressure from anthocyanin intake is not specific to cherry but extend to blackcurrant for older adults. Berry specific effects are possible due to the unique anthocyanin profiles within fruits. For example, cherry is high in the anthocyanin cyanidin-3-glucosylrutinoside while blackcurrant is highest in delphinidin-3-rutinoside, which will then have an impact upon the metabolites produced.22,30 The specific metabolites produced are then determinate of the physiological responses; with Keane et al.31 observing that migration of human vascular smooth muscle cells in vitro was dependent upon the presence of both protocatechuic acid and vanillic acid, rather than in isolation.
