While coffee may be one of the most popular drinks around, millions are forced to do without it because of heartburn, acid reflux, chronic stomach discomfort and other gastrointestinal issues. The problem, it seems, has to do with the very thing that gives coffee so much flavor: the roasting. But that may soon change.
Joseph Schmer, M.D., a gastrointestinal medical specialist and former co-chief of gastroenterology for Methodist Hospital in Brooklyn, NY, has seen for years just how large of a problem stomach issues are for coffee drinkers. “During the coffee-roasting process, natural acids form which can lead to heartburn, indigestion and upset stomach,” he explains. “Reducing these irritants allows coffee drinkers with sensitive stomachs to enjoy coffee.”
People with sensitive stomachs may want to check out brews such as Coffee Legends’ Gentle Java, a new coffee designed specifically for coffee drinkers who say coffee upsets their stomachs. The java is made from an all-natural steam process-popular in Europe for about 60 years-that reduces around 70 percent of all impurities and irritants. The steaming leaves the coffee aroma, flavor and caffeine completely intact-meaning coffee drinkers without sensitive stomachs can enjoy the brew, too.
Gentle Java is good news for those who rely on coffee to help focus or for anyone who wants to benefit from coffee’s antioxidant qualities.
While caffeine has long been known to help asthmatics prevent attacks, recent studies have shown coffee consumption can have several other health benefits.
Drinking coffee has been associated with a lower risk of gallstone disease in men, reduced risk of kidney stone formation and a reduced risk of colon cancer.
Other studies have found coffee to be a good source of potassium, helpful in promoting the effectiveness of migraine medications, and a way of protecting against free-radical damage to tissues. One study found it had more antioxidant activity than red wine, green or black tea or orange juice.
Caffeine, like chocolate, often receives bad publicity. Whilst in some instances, and in excess, these can have negative effects on our body, they can also be quite beneficial.
I am not disputing that some people are more sensitive to the negative effects of either caffeine or chocolate. For example, excess caffeine can create anxiety, nausea (particularly if taken on an empty stomach), an increase in heart rate, and even depression in some people. And chocolate is certainly not something that should form the mainstay of one’s diet. If struggling with sugar addiction, or wanting to lose weight, there are more nutritionally complete foods that are available.
But scientists have turned up some interesting facts on caffeine. For example, caffeine actually blocks the effects of a neurotransmitter in the brain (adenosine) that otherwise makes us feel tired. This is why it works so well to keep us awake. It also encourages the release of another brain chemical, dopamine (as well as adrenaline). Dopamine contributes to a feeling of well being.
Two studies, one a population based study (which are not as specific or rigorously defined as other types of studies, but nonetheless valuable indicators) found that drinking caffeine containing drinks like coffee and tea had a protective effect for those at risk of developing liver disease. Issues that the study participants had that increased their risk of liver disease included alcoholism, hepatitis B or C, obesity, or other complications.
And the results indicated that people who drank more than 2 cups of coffee a day had a 44% lower chance of showing actual liver damage compared to those who drank no caffeine. This was not a clinical trial, and the reason why coffee and tea had such an effect is not known. Coffee and tea contain a range of plant chemicals (phytonutrients) that could be responsible for this. A 2005 Norwegian study also found similar benefits for coffee with regards liver disease. This study found that drinking 3 cups of coffee a day could lower the risk of death from liver cirrhosis.
Even if you’re not at risk of liver disease, caffeine still has some advantages. Recent research from Austria showed that caffeine may actually enhance short term memory. Researchers found that there was an increase in brain activity (as measured by functional magnetic resonance imaging) in the parts of the brain that were associated with memory and attention. These parts of the brain were the frontal lobe and the anterior cingulum. This was a placebo controlled study, meaning that some people were not given any caffeine. Another, earlier study (2004) found that caffeine did support short term memory, but only when it was in relation to a topic that people were already thinking about. This study found that when testing coffee’s effects on unrelated subjects, short term recall was actually inhibited.
Everything does have a flip side though. Adenosine, which is blocked by coffee, is also calming. This could be why it can also cause anxiety in excess, and in some individuals. After all, the balance of our brain chemistry is unique. And when we are addicted to stimulants like caffeine, we lose the sensitivity to our own natural stimulants (dopamine and adrenaline).
Brewing a great cup of coffee depends on a number of things such as the quality of the coffee bean, the quality of the water being used, the type of brewing being done, and the grind of the coffee. Now quality of bean and water is something you can easily take care. Just use good quality beans and pure water. However the relationship between the grind of the coffee and the type of brewing being done is more detailed and could use a little explanation. Now we all know that we make coffee by passing hot water over crushed coffee beans. However for it to really work well we need to understand just how long the water should be passing over the beans. The purpose of this article is to help you understand how to match your coffee’s grind to the type of brewing you are doing in order to make the best coffee possible.
Generally speaking, the ‘soaking’ time relates directly to how coarse the coffee is ground. This means that smaller coffee grinds need less contact with the water, and coarser grinds need longer contact. Espresso coffee is only exposed to water for 20-40 seconds and as a result is made using extremely fine grind coffee. A French press coffee maker can take as much as 4 minutes and uses an extremely coarse grind. If coffee is left contacting water for too long for its grind size, unwanted extracts emerge and make the coffee taste bitter. Of course if the grind is too large and the water passes very quickly (like using frech press grind in an espresso maker), very little of the caffeine and flavours extracted and will have poor flavour.
Of course filters play an important role in managing the balance between over and under brewing your coffee. Not only do they keep the grind out of your cup, but they also control how fast the water passes over the grinds. Paper filters are the most common, but many people are also using metal varieties. Paper filters are quite good. However they can absorb some of the coffee flavour, and some people claim they can taste the paper in the final coffee. Metal filters are normally made from stainless steel or gold plated mesh. They have very fine weave and filter out the coffee grinds very well. They also do not alter the taste of the coffee at all. Metal filters are also more environmentally friendly than the paper alternative.
Whichever you choose, be sure to buy decent quality. Cheap filters often clog or not allow the coffee to brew properly. A decent quality metal filter will last years and save money in the end.
Brewing a cup of coffee is not that hard. Brewing a great cup takes a little more understanding, but isn’t any harder. Start with fresh beans and good clean water and then match your brewing style to the proper grind and then mess around with the exact proportions and pretty soon your be brewing killer coffee every time.
