My Summer Vacation: A Coffee Journal by Michael Sheridan

Some people go to a lake in the Northwoods; others pack up the minivan and head to a Disney resort; others yet gaze upon Mount Rushmore, Niagra Falls or the Rocky Mountains. For his summer vacation, regular Daily Coffee News contributor and CRS Coffeelands blog author Michael Sheridan drinks coffee. Of course, Sheridan can’t be everywhere, but here’s how he spent […]

Qian Xiao et el, 2014, Inverse Association of Total and Decaffeinated Coffee with Liver Enzymes in NHANES 1999 – 2010. Hepatology, published online ahead of print.

Background: Coffee may have hepatoprotective effects and higher coffee consumption has been associated inversely with levels of liver enzymatic markers. However, it is unclear whether decaffeinated coffee is also associated with liver enzymes.
Methods: The study population included 27,793 participants, age 20 or older, in the US National Health and Nutrition Examination Survey (1999-2010). Coffee intake was evaluated by 24-hour dietary recall. Serum levels of aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP) and gamma glutamyl transaminase (GGT) were measured. We examined the relationship between coffee intake and enzymatic levels using weighted multiple variable logistic (abnormally elevated levels of enzymes) and linear regression (continuous enzymatic levels).
Results:  Total coffee consumption was inversely associated with abnormal levels of all four liver enzymes and continuous levels of AST, ALP and GGT. Compared to those reporting no coffee consumption, participants reporting ≥3 cups per day had an odds ratio (OR) (95% confidence interval (CI)) of 0.75 (0.63, 0.89)), 0.82 (0.68, 0.98), 0.73 (0.55, 0.95) and 0.69 (0.57, 0.83) for abnormal levels of ALT, AST, ALP and GGT, respectively. Similar inverse associations were found with decaffeinated coffee intake and abnormal levels of ALT (OR ≥2 vs0 cup/d : 0.62 (0.41, 0.94)), AST (0.74 (0.49, 1.11)), and GGT (0.70, 0.49-1.00).
Conclusion:  Higher intakes of coffee, regardless of its caffeine content, were associated with lower levels of liver enzymes. (Hepatology 2014;).

Coming to Columbus: A New Bar and Roasting HQ for Brioso Coffee

Cafe Brioso, a roastery and cafe that has become a downtown Columbus, Ohio, staple over the past 13 years, is hoping to dramatically increase its production capacity and double its retail presence with the opening of a new headquarters this winter. The Brioso team says the new facility in the Discovery District will have an open floor plan, open cupping and laboratory […]

Inside Denver’s Newest Craft Coffee Bar, The Study at Hotel Teatro

In restaurant conception, it’s always good to have a coffee advocate. In the case of the historic Hotel Teatro in downtown Denver, that advocate was Jake Linzinmeir of the Denver-based restaurant consultancy Blau + Associates, who brought in local Method Roasters early on during a major restaurant redesign. Method is supplying coffee not only to the new Rocky Mountains-inspired restaurant, The Nickel, it’s […]

Say Hello to AltoAir, a Wall-Free Pour Over System from Bairro Alto

The highly design-minded team at British product maker Bairro Alto recently released the AltoAir, a pour over system that visually and functionally more resembles a nest. Here Bairro Alto describes the impetus for the wall-free design: Pour over brewing can yield amazing results, but many people find the filter papers stick to the walls of the brewer and block up. This makes […]

C H Ruxton, 2014, The Suitability of Caffeinated Drinks for Children: a Systematic Review of Randomised Controlled Trials, Observational Studies and Expert Panel Guidance, Journal of Human Nutrition and Dietetics, Volume 27 (4).

BACKGROUND: The increased availability of caffeinated drinks raises questions about the level of caffeine that is appropriate for children, as well as the benefits and risks associated with their consumption.

METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, this systematic review evaluates evidence from randomised controlled trials investigating the effects of caffeine on cognition, behaviour, mood and exercise performance in children. Observational studies and expert panel guidelines are also discussed.

RESULTS: One hundred and nine studies were found, with 11 randomised controlled trials and 13 observational studies meeting the criteria. High caffeine intakes (e.g. >5 mg kg(-1) body weight day(-1) ) were associated with an increased risk of anxiety and withdrawal symptoms. However, smaller amounts were not linked with such effects and may benefit cognitive function and sports performance based on adult studies. The evidence suggests that children and adolescents should limit daily caffeine consumption to 2.5 mg kg(-1) body weight day(-1) , equating to one or two cups of tea or one small cup of coffee. Lower contributors of caffeine, such as tea, may be more appropriate for children because they contribute to daily fluid intakes and provide flavonoids. By contrast, caffeinated soft drinks may be less suitable options for children as a result of their acidity, higher caffeine content, presence of added sugar (in some cases) and absence of bioactive compounds.

CONCLUSIONS: More studies are needed to determine the intakes that represent a risk and whether there may be benefits for alertness and sports performance with moderate intakes of caffeine.

I Guessous et al, 2014, Blood pressure in relation to coffee and caffeine consumption, Current Hypertension Reports, published online ahead of print.

Abstract

The relationship between blood pressure (BP) and coffee is of major interest given its widespread consumption and the public health burden of high BP. Yet, there is no specific recommendation regarding coffee intake in existing hypertension guidelines. The lack of a definitive understanding of the BP-coffee relationship is partially attributable to issues that we discuss in this review, issues such as acute vs. chronic effects, genetic and smoking effect modifications, and coffee vs. caffeine effects. We also present evidence from meta-analyses of studies on the association of BP with coffeeintake. The scope of this review is limited to the latest advances published with a specific focus on caffeine, acknowledging that caffeine is only one among numerous components in coffee that may influence BP. Finally, considering the state of the research, we propose a mechanism by which the CYP1A2 gene and enzyme influence BP via inhibition of the adenosine receptor differentially in smokers and non-smokers.

Canadian Coffee Shop Owners Detained by China on Suspicion of International Espionage

Two Canadians who until last week were running a coffee shop on the China/North Korea border are being detained by the Chinese government for suspected theft of military intelligence and threats to national security, according to China’s Foreign Ministry. Vancouver couple Kevin Garrett and Julia Dawn Garratt opened Peter’s Coffeehouse Dandong, Liaoning province, a gateway city to North Korea, in 2008, after years […]
