Despite extensive research, the cardiovascular effects of coffee consumption in humans remain controversial. Our aim was to investigate the excretion of coffee phenols and the effects of filtered coffee consumption on oxidative stress and plasma homocysteine (tHcy) concentration in humans. The study consisted of a multiple-dose clinical supplementation trial and a single-dose study. In the long...

Coffee drinking may be associated with reduced risk of endometrial cancer; however, prospective data are limited. Further, it is not clear whether any association between coffee and endometrial cancer differs according to coffee caffeine content. The association of coffee drinking with incidence of endometrial cancer was evaluated among 226,732 women, aged 50-71, enrolled in the NIH-AARP Diet a...

Coffee is one of the most popular and widely consumed beverages worldwide due to its stimulating effects on the central nervous system as well as its taste and aroma. Coffee is a complex mixture of more than 800 volatile compounds whereas caffeine and chlorogenic acids are the most common compounds. During the last years, coffee has progressively moved to a less negative position on health due ...

BACKGROUND Coffee consumption has been shown to be inversely associated to type 2 diabetes mellitus (T2DM), but evidence in Chinese populations is limited. We investigated the relationship between coffee consumption and T2DM in a population-based cohort of middle-aged Chinese. MATERIALS AND METHODS We studied 2332 subjects who participated in the Taichung Community Health Study in Taiwan in 2...

melamine is a potentially hazardous compound and one of the major concerns especially in dairy products and pet foods. in the present study a sensitive, simple and reliable method for extraction and determination of melamine in infant milk and coffee mate has been developed. this method consists of an initial extraction in buffer media prepared by formic acid and sodium formate, followed by pro...

BACKGROUND The consumption of unfiltered coffee, containing bioactive diterpenes, causes an increase in plasma homocysteine concentration. A slight increase in plasma homocysteine is also caused by large quantities of filtered coffee. Coffee terpenes also raise plasma glutathione in mice. AIM To verify the effect of Italian-style coffee consumption on the plasma concentration of glutathione a...

Ochratoxin A (OA) is a nephrotoxic and nephrocarcinogenic mycotoxin which is predominantly produced by the two ubiquitous fungal genera, Aspergillus and Penicillium. OA is found in foodstuffs, predominantly in cereals but also in coffee beans. Inconsistent results have been published regarding the influence of roasting on the OA content in roasted beans and the transfer into the coffee brew. In...

Recent epidemiological studies have shown that moderate coffee consumption is associated with a lower risk of certain types of cancers, particularly colon cancer in postmenopausal women. To elucidate the molecular basis for the preventive action of coffee, we investigated the effect of coffee on estrogen sulfotransferase (SULT) because sulfation is the major pathway involved in the inactivation...

BACKGROUND Epidemiologic studies suggest that coffee use might protect against colorectal cancer. Inconsistencies as to the effect of coffee use and colorectal cancer between epidemiologic studies might be related to the type of coffee brew. OBJECTIVE We studied the effect of unfiltered coffee consumption on putative biomarkers for colonic cancer risk. DESIGN A total of 64 healthy volunteer...

CONTEXT Population study data about relations of coffee drinking to arrhythmia are sparse. OBJECTIVE To study relations of coffee drinking to risk of cardiac arrhythmia in 130,054 persons with previous data about coffee habits.Design and Outcome Measure: We used Cox proportional hazards models with 8 covariates to study coffee-related risk in 3137 persons hospitalized for cardiac arrhythmia. ...
