PURPOSE Anecdotal evidence suggests that patients with painful bladder syndrome/interstitial cystitis report symptom exacerbation after consuming particular foods, beverages and/or supplements. We determined the prevalence of the effect of comestibles on painful bladder syndrome/interstitial cystitis symptoms and identified particular comestible items more likely to affect such symptoms. MATE...

Many studies have indicated that consumption of vegetables and fruits are positively related to lower incidence of several chronic noncommunicable diseases. Although composition of fruit and vegetable juices is different from that of the edible portion of fruits and vegetables, they contain polyphenols and vitamins from fruits and vegetables. Drinking vegetable and fruit juices is very popular ...

Background: Contamination of fruit juices with heavy metals presents a risk for human health. Concentrations of lead, and arsenic in fruit juices of market in Mashhad, Iran, were measured using atomic absorption spectrometry (AAS). Methods: Fifty varieties of commercial fruit juices (grape, apple, orange, pomegranate, and multi-fruit) from 5 popular brands (A, B, C, D and E) were purchased fro...

The levels of trans-piceid, cis-piceid, trans-resveratrol, and cis-resveratrol have been measured in 36 grape juices using an HPLC system with spectral analysis of eluting peaks. The piceid (glucosides) were the major component in the grape juices. In red grape juices the average concentrations were 3.38 mg/L for trans-piceid, 0.79 mg/L for cis-piceid, 0.50 mg/L for trans-resveratrol, and 0.06 ...

Human organic anion-transporting polypeptide B (OATP-B; OATP2B1) is expressed in the human intestinal epithelial cells, and is suggested to be involved in the intestinal absorption of anionic drugs in vivo. Although citrus juices have been shown to inhibit the function of human OATP-A (OATP1A2), the effect of citrus juices on the OATP-B function remains unclear. In this study, we aimed to exami...

Pectin methylesterase (PME) rapidly hydrolyzes pectin methylesters in cold break tomato juice to form methanol and to increase titratable acidity (TA). Within 30 min, the juice methanol concentration increased from 35 to over 400 lg g 1 while the pH dropped from 4.45 to 4.20. On average, cold break juice pH values were 0.21 U lower and TAs 12.4 leq g 1 higher than those for hot break juices pre...

Strains of Lactobacillus plantarum were grown and stored in cherry (ChJ), pineapple (PJ), carrot (CJ), and tomato (TJ) juices to mimic the chemical composition of the respective matrices. Wheat flour hydrolysate (WFH), whey milk (W), and MRS broth were also used as representatives of other ecosystems. The growth rates and cell densities of L. plantarum strains during fermentation (24 h at 30°C)...

It is well known that eating fruits and vegetables lowers the risk of chronic diseases such as heart disease and cancer. The question of what is/are the active ingredient(s) is still unresolved. The initial hypothesis was that the antioxidant vitamins were responsible. However, recently the polyphenols have been investigated since they have been found to have beneficial properties such as being...
