Like caffeine? There's a gene for that -- two of them, actually

Attention coffee drinkers: If you think your craving for a cuppa joe stems from sleepiness, habit or simply a desire to make Starbucks CEO Howard Schultz an even richer man, you are sorely mistaken. A team of researchers from Harvard, the National Cancer Institute and other esteemed institutions of biological science reports that our need for caffeine is in our DNA. As if there were any part of our lives that weren’t subject to genetics in some form or fashion.

But back to the so-called caffeine genes. There are two of them, according to a report published Tuesday in PLoS Genetics.The first is CYP1A2, which had already been known to have something to do with caffeine metabolism, and the second is AHR, which plays a role in regulating CYP1A2.

Everyone has both of these genes, of course, but we don’t all have the exact same kinds. Those in the study who had the most caffeine-seeking version of CYP1A2 drank an average of 38 milligrams more of the stuff each day than those with the most caffeine-indifferent version. People with the most caffeine-dependent version of the AHR gene consumed an average of 44 mg. more per day than their counterparts with the least caffeine-seeking version.

Fast food breakfast? Think twice about having that coffee‎

If your morning commute usually includes a greasy breakfast sandwich and a stiff cup of joe, here's another reason to trade it all in for a fruit cup. A new study from the University of Guelph found that chugging a coffee after a fatty meal of fast food can spike blood sugar in a healthy person to a level similar to those at risk of diabetes. Eating a greasy meal, we already knew, caused spikes in blood sugar. But the dangerous cocktail of caffeine and grease doubles the impact.

Researchers at the University of Guelph say that eating saturated fat makes it harder for the body to clear sugar from the blood - drinking coffee, even a couple of hours later, only makes that job harder. "This shows that the effect of a high-fat meal can last for hours," said Marie-Soleil Beaudoin, a PhD student who conducted the study with University of Guelph professors Lindsay Robinson and Terry Graham.

In the study, published in the Journal of Nutrition, participants were given a special fat beverage, and then asked to eat a meal with a sugar drink six hours later. Typically, the body should produce insulin to remove sugar from the blood. (People with diabetes do not produce enough insulin.)

But with the high-fat beverage in their system, the blood sugar levels in participants were 32 per cent higher than those who had not consumed any fat. And in the second part of the experiment, when participants were also asked to drink two cups of coffee five hours after the fatty drink and then down a sugar beverage, blood sugar levels were 65 per cent higher than the control group.

"Having sugar remain in our blood for long periods is unhealthy because it can take a toll on our organs," said Ms. Beaudoin, in a release from the university. The study, she said, stresses the need for people at risk of diabetes or with the disease to avoid both high-fat foods and limit their caffeine.

Coming Soon To Your Mug: Temperature-Regulating Coffee Widgets

Coming Soon To Your Mug: Temperature-Regulating Coffee WidgetsA couple of engineer buddies have designed the latest must-have accessory for the coffee drinker. Joulies are metallic beans you drop into your hot cup of coffee to make it exactly 140 degrees. They haven't even been manufactured yet, but already the project has accumulated some $35,000 in Kickstarter cash. I guess a lot of people are tired of blistered tongues.

Each Joulie is a small metal shell filled with a phase-change material that melts at 140º Fahrenheit. (Some people might prefer 155º -- perhaps there will be a version for us.) So the Joulies absorb heat from the coffee till they reach 140º, and then start emitting heat. The effect (if you put in enough Joulies for your volume of beverage) is to maintain the coffee at the desired temperature for long enough to savor it. Using an insulated cup is recommended also.

We've seen this idea before, in the form of Fraunhofer's Perfect Coffee Mug, but this time it seems poised to actually come out of the lab and into your cup.

Coffee lowers stroke risk in women

Coffee lowers stroke risk in womenConsuming more than a cup of coffee a day is linked to a 22 per cent to 25 per cent lower risk of stroke, says a new study. Low or no coffee consumption is associated with an increased risk of stroke, according to the study of 34,670 women (ages 49 to 83) followed for an average 10.4 years. It’s too soon to change coffee-drinking habits, but the study should ease the concerns of some women, researchers noted. Coffee is one of the most widely consumed beverages in the world.

“Therefore, even small health effects of substances in coffee may have large public health consequences,” said Susanna Larsson, lead author of the study and a researcher in the Division of Nutritional Epidemiology, National Institute of Environmental Medicine, Karolinska Institute in Stockholm, Sweden. The study has been reported in Stroke: Journal of the American Heart Association.

Dropping The Drip: How To Get Started With Better Coffee Making

Dropping The Drip: How To Get Started With Better Coffee MakingLike computers, coffee is complex, easy to sink money into, and attracts a vast swath of opinions. And like computers, there is a wise middle path you can walk to get top-notch coffee at home without spending MacBook-like money on brewing gear.Image via Mat Honan.

What will you get out of this treatise on slightly snob-ish coffee? A better understanding of why the standard means of buying, storing and making coffee leaves much to be desired, followed by a rundown of some of the better, and less expensive, coffee-making methods — what I call hand-crafted coffee — and how it’s sometimes faster, and usually more fun, than making a pot of the classic drip stuff or just sticking with instant.

There are two things you should know up front. First: I’m not a coffee expert. In fact, as of a month ago, my coffee came primarily from baristas, a Keurig single-serve machine (photographic evidence here, a standard drip machine, or, on leisurely weekends, a French press that I knew two-thirds of the instructions for. To rectify this, I spent a month experimenting with at-home coffee methods, foisting blind taste tests on friends and co-workers, and researching what I call the Taste-to-Fuss Ratio. I also betrayed everything I once held dear about caffeine dependency.

Second: Your taste in coffee is different to mine. You might be looking for a smooth, gentle cup to accompany your drive to work, while I’m hoping my next cup tastes like pure Arabic gold. You get the freshest, single-source beans you can find from a local source, while I’m okay with the occasional cup of Eight O’ Clock.

What You Get by Leaving Automatic Drip Behind

Standard drip coffee makers have their uses. Automatic timers can be mighty helpful, especially the night before you fly out. If you’re making coffee for ten people after dinner, it’s easy to just load up, hit a button, and meet standard expectations. In my blind tests, too, some drinkers, given the right beans, ranked certain cups of drip above the hand-crafted competition.

But there are means of making coffee at home that can take less time than a drip maker. And you’re making a few sacrifices for set-and-forget:

• You usually use twice as much coffee: Water drains through ground coffee in an automatic machine at a relatively rapid pace, getting less direct exposure to the stuff than with most other means. That’s why most bags of good coffee suggest using two tablespoons per six-ounce serving. It’s a tablespoon here and there, but it adds up quickly if you actually drink the stuff.

• You can’t adjust two of three key elements: The key variables in coffee making are water temperature, the amount of coffee used in relation to the water, and the amount of time the coffee is brewed with the water. With a drip coffee maker, you can only control one of those three elements, and not that precisely.

• Lingering, hard-to-clean tastes: It’s relatively easy to clean out a glass carafe or metal container after you make coffee with it—you kind of have to, actually. Unless you’re meticulous about cleaning your drip maker after each use, its tubes and crevices accumulate residues, and the carafe itself usually smells faintly of whatever was last inside it.
The Tools of the Better Coffee Trade

To get better coffee, you need to to expose hot water to more high-quality coffee. That means doing a few things differently than you’re told by mass coffee merchants. Buy freshly roasted coffee:
Hopefully, somewhere near you, there’s a coffee merchant that roasts beans on-site and stamps their coffee with the date they roasted it. If you can’t find that merchant, find one in the area that sells to a nearby store. If that’s out of the realm, and you’re really game for committing to better coffee, consider buying your own green beans and roasting them yourself. It’s probably not as hard as you might think, and you’ll actually have some real coffee nerd bragging points. Image via B*2.

I didn’t quite get the impact of fresh-roasted coffee until a recent trip to Los Angeles, during which I visited Intelligentsia in Silver Lake. The cappuccino was strong — not heavy, not bitter, but just muscular in its flavour. The single-origin beans on the shelf were so fragrant, I grabbed them more than once during stops in LA traffic for quick aromatic stress relief. It got ridiculous — I could convince myself that Intelligentsia was “on the way” if it only added 6km to a straight-shot trip. Ask Whitson.

Six new zones to raise coffee output to 100,000 tonnes

Six new zones to raise coffee output to 100,000 tonnesThe Tanzania Coffee Board (TCB) has identified six new areas that are potential for coffee production, making a total of 13 regions undertaking coffee cultivation countrywide. In an interview this week, TCB Director General eng. Adolph Kumburu, said the board will sensitise farmers to plant Tanzania Coffee Research Institute’s (Tacri) newly researched varieties in the areas.

The aim is to increase coffee production to 100,000 tonnes by the year 2020, according to the board DG. He said TCB Ffeld officers have been stationed in all coffee producing zones where offices had been established in 2009. Shedding more lights on the new strategy, Kumburu said it is a collaborative effort by industry stakeholders and has been developed as a result of new developments in the coffee industry.

They include amendment of the Crop Board Act and implementation of the new Crop Board reforms, he said. According to him, the strategy sets out a mission on how to increase coffee production from the present 50,000 metric tonnes to at least 80,000 tonnes by 2016 and reach 100,000 tonnes four years thereafter.

It is envisaged that the increase in production volumes will go hand in hand with the increase in quality from the present 35 per cent premium coffee to at least 70 per cent of total production. The move by the Board and stakeholders has comes at the right time when the price of coffee in world market has been soaring.

World coffee price in December last year reached the highest level since October 1994, according to the International Coffee Organization (ICO). The trend led to a sharp rise in the monthly average of the ICO composite indicator price from 173.90 US cent in November, to 184.26 US cents per pound in December.

According to ICO report, world coffee exports reached 7.6 million bags in November last year in contrast to 6.7 million bags over the same period in the previous year. The report says exports in the first two months of 2010 / 2011 (October and November) increased by 9.3 per cent to 15.6 million bags, compared to 14.2 million bags in the same period during the previous year.

During the past twelve months which ended in November last year, exports of Arabica coffee totalled 63.2 million bags compared to 61.1 million bags the previous year. On the other hand, Robusta exports amounted to 31.8 million bags compared to 36.2 million bags over the the period under review.

Tanzania is Africa’s largest coffee producer after Ethiopia, Uganda and Ivory Coast. Approximately seventy percent of coffee produced in Tanzania is Arabica, with most of it grown in the high altitude regions of Mount Kilimanjaro, Arusha and Mbeya.
