Increased public awareness of health benefits of green tea is generally based on the high polyphenol content of tea leaves and the resulting beverage. A number of factors, such as species, season, agronomic condition and age of the leaves, are known to affect the composition of commercial teas. In the present study the effects of factors associated with domestic preparation and analytical metho...

Epidemiological studies have argued that green tea could mitigate diabetes and its complications. This study investigated the phytophenolic profile of Mauritian green tea and its antioxidant propensity. The effect of green tea on the risk factors: waist-hip ratio, glucose level, arterial pressure, antioxidant status, and alanine aminotransferase (ALT) in prediabetics was assessed. The experimen...

BACKGROUND Coffee and tea are widely consumed globally and are rich sources of potential chemopreventive compounds. Epidemiologic data for coffee and tea intakes in relation to colorectal cancer remain unclear. Despite differences in gut physiology, few studies have conducted investigations by anatomic subsites. OBJECTIVE We evaluated coffee and tea intakes (caffeinated and decaffeinated) in ...

Objectives: This study aims to evaluate the possible relationship between oral consumption of hot black tea and methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage in a mid-sized town population in central Anatolia. Patients and Methods: Nasal swabs were taken from a total of 109 subjects (53 females, 56 males; mean age 34.4 years; range 18 to 65 years) including 55 non-tea drinke...

We are concerned about the media purporting that drinking six or more cups of coffee per day can prevent lethal prostate cancer, following publication of the Harvard report (1). Such “advice” has been given prominence in the Australian, Chinese, and Korean news media, just to name a few. In the Health Professionals Follow-up Study, coffee intake was measured by cups per day, and separate analys...

BACKGROUND Caffeine and related methylxanthine compounds are recognized as having a diuretic action, and consumers are often advised to avoid beverages containing these compounds in situations where fluid balance may be compromised. The aim of this review is to evaluate the available literature concerning the effect of caffeine ingestion on fluid balance and to formulate targeted and evidence-b...

Prostate cancer (PCa) now remains the 2nd most frequently diagnosed cancer. In recent years, chemoprevention for PCa becomes a possible concept. Especially, many phytochemicals rich foods are suggested to lower the risk of cancer. Among these foods, green tea is considered as effective prevention for various cancers. However, clinical trials and previous meta-analyses on the relationship betwee...

Abstract Sanitation facility conditions and waste disposal practices are hypothesized to affect the fecal contamination of drinking water kitchenware. The present study aimed examine physical sanitation facilities locations as well determine concentrations Escherichia coli in water, cups, dishes, flies, toilet floors, kitchen floors. A total 336 samples were collected from 17 households peri-ur...

background: two of the important radionuclides which are entered to environment and human diet are radium-226 (226ra) and cesium-137 (137cs). it is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. an experiment has been performed at the environmental monitoring section...

Background: Lead (Pb) is a pervasive metal that can be found in, and potentially leached from, ceramics, particularly into acidic foods and beverages. The purpose of this study was to investigate potential lead exposure from coffee and tea consumption, given that both are acidic and routinely consumed from ceramic mugs. We measured the concentration of lead in coffee and tea at two different ti...
