Health Benefits
A. Health benefits according to studies
1. Liver diseases
In the research of prunes (Prunus domestica) and its effect on liver function, found that There was significant reduction of serum alanine transaminase (p 0.048) and serum alkaline phosphatase (p 0.017) by the lower dose of prunes. There was no change in serum aspartate transaminase and bilirubin. Alteration in liver function by use of prunes may have clinical relevance in appropriate cases and prunes might prove beneficial in hepatic disease, according to "Report: prunes and liver function: a clinical trial" by Ahmed T, Sadia H, Khalid A, Batool S, Janjua A.(a)

2. Hypertension
In the investigation of prunes (Prunus domestica) and its effect on blood pressure found that there was significant reduction of blood pressure by single dose of prunes daily group and the controls (p < 0.05). With the double dose of prunes, only systolic BP was reduced significantly (p < 0.05), according to "Use of prunes as a control of hypertension" by Ahmed T, Sadia H, Batool S, Janjua A, Shuja F.(b)

3. Antioxidants
In the evaluation of Nine different beverages, including prune juice and their free radical scavenging activity found that there was an almost 7-fold difference in the Total Oxyradical Scavenging Capacity (TOSC) between brewed coffee and ascorbic acid. The data suggest a potential role for commonly consumed beverages in lowering the risk of pathophysiologies associated with peroxyl radical-mediated events, according to "Comparison of peroxyl radical scavenging capacity of commonly consumed beverages" by Kwon do Y, Choi KH, Kim SJ, Choi DW, Kim YS, Kim YC.(c)

4. Cognitive effects
In the observation of prune juice and normal aging in animals and humans is accompanied by a decline in cognitive performance indicated that rats that drank plum juice from 19 to 21 mo of age had improved working memory in the Morris water maze, whereas rats fed dried plum powder were not different from the control group, possibly due to the smaller quantity of phenolics consumed in the powder group compared with the juice group. These results are discussed in relation to the amount and type of phenolics present in the plum products and in relation to other dietary intervention studies in which cognitive benefits have been reported, according "Plum juice, but not dried plum powder, is effective in mitigating cognitive deficits in aged rats" by Shukitt-Hale B, Kalt W, Carey AN, Vinqvist-Tymchuk M, McDonald J, Joseph JA.(d)

5. Human colon carcinoma Caco-2
In the study of the dried fruits of certain cultivars of Prunus domestica L. extract and its effect Caco-2, KATO II found that PE treatment for 24 h led to apoptotic changes in Caco-2 such as cell shrinkage and blebbed surfaces due to the convolutions of nuclear and plasma membranes and chromatin condensation and induced apoptosis in Caco-2, acording to "Prune extract (Prunus domestica L.) suppresses the proliferation and induces the apoptosis of human colon carcinoma Caco-2" by Fujii T, Ikami T, Xu JW, Ikeda K.(e)

6. Hypercholesterolemia
In the identification of Forty-one free-living adult men with mild hypercholesterolemia (5.2-7.5 mmol/L) voluntarily participated in an 8-wk crossover study designed to determine the effect of prunes as a source of fiber on plasma cholesterol and on fecal output and bile acid concentration found that During theprune period, subjects supplemented their usual diets with 12 prunes (100 g; 6 g dietary fiber) daily. Plasma low-density-lipoprotein cholesterol was significantly lower after the prune period (3.9 mmol/L) than after the grape-juice-control period (4.1 mmol/L). Fecal bile acid concentration of lithocholic acid was significantly lower after the prune period (0.95 mg bile acid/g dry wt stool) than after the grape-juice-control period (1.20 mg bile acid/g dry wt stool), according to "Consumption of prunes as a source of dietary fiber in men with mild hypercholesterolemia" by Tinker LF, Schneeman BO, Davis PA, Gallaher DD, Waggoner CR.(f)
