Different studies have shown that milk may interact with polyphenols and affect their bioavailability in humans. The present study investigated the effect of the simultaneous consumption of coffee and milk on the urinary excretion of chlorogenic acids (CGA) and metabolites. Subjects were submitted to consumption of water, instant coffee (609 mmol of CGA) dissolved in water, and instant coffee d...

Coffee is a popular beverage in society. Acrylamide is an undesirable substance that will metabolically activated to carcinogens.Acrylamide formation is found to occur during the browning process, which is called Maillard reaction. This is the reaction between sugars and asparagines at temperature above 120°C. The roasting temperature of coffee is at least 200°C, meaning that coffee surely cont...

Caffeine is by far the most commonly used psychoactive substance. Caffeine is consumed regularly as an ingredient of coffee. Coffee consumption and coffee preference was explored in a sample of 4,495 twins (including 1,231 pairs) registered with the Netherlands Twin Registry. Twin resemblance was assessed by tetrachoric correlations and the influence of both genetic and environmental factors wa...

BACKGROUND The association between consumption of caffeinated and decaffeinated coffee and risk of mortality remains inconclusive. METHODS AND RESULTS We examined the associations of consumption of total, caffeinated, and decaffeinated coffee with risk of subsequent total and cause-specific mortality among 74,890 women in the Nurses' Health Study (NHS), 93,054 women in the Nurses' Health Stud...

1. Ants are important predators in agricultural systems, and have complex and often strong effects on lower trophic levels. Agricultural intensification reduces habitat complexity, food web diversity and structure, and affects predator communities. Theory predicts that strong top-down cascades are less likely to occur as habitat and food web complexity decrease. 2. To examine relationships betw...

coffee shops have always played a key role and have affected the shaping and stability of important parts of social cultures and traditions as well as public rituals. although this effectiveness during different periods has been associated with distinct ups and downs, a number of traditional religious and other kinds of shows such as minstrelsy, eloquence, curtain narration and tornabazi have b...

Introduction Intensify, innovate, and specialize—this was the essential message for governments and donors looking to address the devastations of the coffee crisis in Central America and other coffee-producing regions. Between 1999 and 2005, prices paid for green coffee did not allow producers in Central America to cover their variable costs of production (IADB 2002). Most smallholders reduced ...

Determining the permeability of different types of landscape matrices to animal movement is essential for conserving populations in fragmented landscapes. We evaluated the effects of habitat patch size and matrix type on diversity, isolation, and dispersal of ithomiine butterflies in forest fragments surrounded by coffee agroecosystems in the Colombian Andes. Because ithomiines prefer a shaded ...

Nicaraguan smallholder cooperative leaders working in partnership with a California-based small-scaleroasting company pioneered an alternative approach to confronting the post-1999 coffee crisis. They builtcoffee tasting laboratories and integrated grassroots organizing efforts to create a national smallholdercooperative association that dramatically improved the quality, consistenc...

Coffee roasting affects the taste, color, and aroma of coffee. The Maillard reaction, a major reaction during the roasting process, produces melanoidin, which affects the overall antioxidant capacity and anti-inflammatory effects of coffee. In this experiment, coffee roasting was divided into four degrees: Light, Medium, City, and French. To examine the in vivo antioxidant and anti-inflammatory...
