What exactly is the difference between black coffee and milk coffee? Are black coffee and Americano both the same? Follow us so you can learn more about coffee.
Americano vs American Coffee vs Black Coffee
"Americano" (Italian: Caffè Americano), a type of coffee, is also the most common form of coffee. It is made by blending hot water into espresso. Americano is light and clear, almost transparent, and you can even see the brown coffee at the bottom of the cup.
Another name for coffee, American Coffee, is American-style drip coffee, which has nothing to do with American-style coffee and is the same as European drip coffee, but lighter than European drip coffee. The boundaries of American-style coffee are rather blurred, which is related to the spontaneous lifestyle of Americans and their love of freedom, and there is no strict definition of American-style coffee. But generally American-style coffee has some common points, such as light taste, light, and clear color
Black coffee is a coffee with no added sugar, no added milk, and no other flavoring added. Black coffee can be a single coffee or a blended coffee. The ingredients used are the same, but the ratio, the order of preparation, the coarseness of the coffee beans, the extraction time, and other conditions are slightly different, the taste and flavor may be different, but they can all be collectively called black coffee.
For example, Americano and Long Black (some call them light black coffee)
In Americano and Long Black, the ratio of espresso to water = 1:2, but Americano is water added to espresso, while Long Black is filled with water first, then espresso is added in. long Black will have more coffee cream on the surface than Americano.
Both are made with espresso and hot water but in a different orders. They are treated as two different coffees because of the difference in taste, flavor, and appearance. But we can call them both black coffee.
Black coffee and Americano are included and included, and that is to say, Americano is black coffee, black coffee is not necessarily Americano.
What is Black Coffee
Black coffee is unadorned coffee, black coffee brings the original feeling of tasting coffee. Coffee made with a small home coffee machine, visually see the foam on the coffee, brewed properly, the foam should be uniform yellow-brown.
If the coffee bean composition is mostly of the Arabica variety, the foam is fine, dark brown with a slight reddish tinge.
If it is mostly Robusta, the foam is loose and dark brown with gray streaks.
A cup of delicious coffee, for black coffee fans, in addition to the sweet and mellow taste, is most attractive than the coffee in the process of brewing out of a slightly mysterious and attractive aroma. Therefore, the so-called taste of a cup of coffee should be from the moment the coffee is brewed.
After the coffee is brewed, you should smell its aroma and then look at its color before tasting it; only coffee with clear color can bring a fresh and round taste to the mouth. Then sip the coffee in small sips, not rushing to drink the coffee at this time, you should first temporarily hold it in your mouth, let the coffee mix slightly with saliva and air, while feeling the coffee in different parts of the mouth, and then gently let the coffee into the stomach.
Such a combination of smell, vision, taste, and appreciation, to truly appreciate the essence of a cup of black coffee. In this way, you can enjoy the original aroma, sweetness, acidity, and bitterness of black coffee in a balanced taste.
Effect of Black Coffee on the body
A growing number of experiments are studying the effects of coffee on human health. People who drink 4-5 cups of coffee a day (which is moderate) have less chance of getting type 2 diabetes, Parkinson's, Alzheimer's, and high blood pressure compared to people who don't drink coffee. There is also a reduced chance of some cancers, heart rate problems, and strokes.
However, coffee has not been shown to prevent any of these diseases. Most of these experiments were done with cross-sectional studies, all of which were observational experiments. This method of experimentation is mainly observed and recorded by the experimenter. It is possible to find a link between the subject (in this case coffee) that one wants to study and health. The link can be seen, but the results of the experiment do not prove a causal relationship. At the end of the experiment, the area of discussion, people may speculate that it has to do with the fact that the coffee lovers in the experiment may have a healthier diet structure, love to exercise, do not have the above genes for chronic diseases, etc. to refute the results of the resulting experiment.
So, there are these experiments, but the results of these experiments are probably not true.
Note: A cross-sectional study is a collection and description of the characteristics of a population and its disease or health status on an individual basis for a certain range of people at a given time. It is the most widely used method in describing epidemiology.
Potential Benefits
1. Type 2 diabetes and the experiment with coffee
In 2009, Dutch scientists claimed that coffee is likely to prevent type 2 diabetes. The results of the experiment showed that drinking more than 3 cups of tea or coffee a day can reduce the chances of getting type 2 diabetes by 42%. The experiment was conducted by Utrecht University Medical Center. The results of the experiment were derived from the results of 40,000 evaluated questionnaires. According to the data analysis, both tea and coffee showed a tendency to reduce type 2 diabetes. The intake of magnesium, potassium, and caffeine did not strongly explain the link with blood pressure.
On the opposite side - Dr. James Pickett, a research center officer at Diabetes UK, responded: "This is an interesting experiment. But it does not prove that tea and coffee are effective in preventing type 2 diabetes because many other factors influence whether a person has diabetes or not".
On the positive - Frank Hu, a professor of nutrition and epidemiology at Harvard University, disagrees with Dr. James Pickett's opinion. He thinks the results of these experiments are very convincing (pretty solid), given that 15 published experiments had similar results. He said, "Most of the experiments showed the health benefits of coffee, and some of them also showed the health benefits of decaffeinated coffee.
2. Heart disease, stroke, and coffee
Following the results of the above study, coffee has inhibited the development of diabetes. Diabetes can increase the chances of heart disease and stroke. In addition, coffee intake can reduce the chance of heart arrhythmia. Heart arrhythmia is another predisposing factor for heart attack and stroke.
In 2009, a long-term follow-up trial was conducted to investigate the impact of nurses' coffee drinking habits and health. Nurses who drank 2-3 cups of coffee a day were 20% less likely to have a stroke than other nurses who did not drink or drank less. The experiment was simple and did not take into account the effects of many other factors on the nurses' bodies, such as blood pressure, high cholesterol, or diabetes.
In 2010, the American Heart Association recommended that moderate coffee drinking is good for the heart. The British Heart Association states that a simple life change: drinking coffee. The benefits of heart disease are not nearly as pronounced as those from a healthy lifestyle (diet, exercise, etc.).
3. Parkinson's, Alzheimer's, and coffee
In 2010, a trial showed that people who drank 2-3 cups of coffee a day could effectively prevent Parkinson's by reducing their chances of getting Parkinson's by 25%.
In 2009, a 20-year follow-up study in Finland and Sweden showed that among 1,400 subjects, those who drank 3-5 cups of coffee a day had a 65-70% lower chance of getting Alzheimer's and a 62-64% lower chance of getting Alzheimer's disease compared to those who drank occasionally and those who did not. Although the data show that caffeine can effectively reduce cognitive degeneration, but can advise the public that drinking coffee can 100% can prevent Parkinson's and Alzheimer's, which is too hasty.
The president of the British Parkinson's Association said, "These findings suggest that caffeine intake has a role in preventing Parkinson's, but these experiments do not tell us whether Parkinson's can be slowed down if it has already started. Although the results of these experiments are interesting, it's too early to make any definitive conclusions." Widespread promotion of coffee drinking to prevent Parkinson's would be too hasty. Drinking too much coffee may have negative health effects.
4. Cancer and coffee
The International Agency for Research on Cancer (IARC), a division of the World Health Organization, announced in 2016 that there is no evidence that coffee is a carcinogen. Since 1991, the WHO has classified coffee as a "potential carcinogen".
Previously, coffee was classified as a carcinogen, probably because people like to drink it "hot" (above 149°F, which can cause esophageal cancer in the long term).
5. Osteoporosis and coffee
I often hear people say: drinking too much coffee will lead to osteoporosis. This statement is only half right. Drinking more coffee does lead to calcium loss and thus causes osteoporosis. But how much does "too much" mean? The British National Osteoporosis Association says that excessive coffee consumption, where excessive means drinking 8 cups of coffee a day and more will show signs of calcium loss.
6. Coffee and sports performance
Coffee can improve sports performance. The European Food Safety Authority says caffeine can improve endurance levels. Before exercise, the effective dose of intake = 3mg x body weight (KG) / hour. Example: 50KG, I plan to exercise for 1 hour, that is 150mg of caffeine before exercise, a cup of half black tea.
Potential Disadvantages
1. Calorie problem: coffee itself is not high in calories, and even before there are coffee weight loss products. But the general drinking coffee will add sugar, cream, and flavored syrup (similar to those of Starbucks). Is later added to these making coffee drinks high-calorie.
2. Pregnant women miscarriage and premature birth: the current experimental results are not conclusive, but the experimental results show that for pregnant women during pregnancy, drinking high doses of coffee will increase the risk of late pregnancy miscarriage and premature birth (University of Leeds, UK 2010).
The UK NHS recommends that caffeine intake during pregnancy should not exceed 200mg per day, which is equivalent to two cups of instant coffee or one and a half cups of freshly ground coffee. However, the caffeine content of coffee sold in coffee shops can be much higher, and previous quantification results will not be accurate.
3. Drinking coffee in the morning on an empty stomach will stimulate the gastric acid secretion and increase the concentration of gastric acid, and drinking large amounts of strong coffee will lead to stomach pain and nausea. People with upset stomachs are not recommended to drink black coffee (including decaffeinated coffee), which can aggravate the feeling of heartburn and is not conducive to recovery.
Black Coffee Q&A
1. Can coffee lose weight?
Studies show that: athletes who take the right amount of caffeine before training, 3 hours calories burned 15% more than usual, but only if they exercise to do so. Drink a cup of coffee about 45 minutes before exercise, to ensure that caffeine just at the time of training began to work in the body, so exercise "before" 45 minutes to drink a cup of coffee is most beneficial.
2. Can I drink instant coffee?
Sometimes we choose instant black coffee (including freeze-dried coffee) for convenience. If the ingredients list shows "100% coffee beans", "ground coffee powder", and no phyllo, sugar, or other ingredients of the flower, only called black coffee. Although the taste of coffee with sugar is good, but can not avoid adding additives, it is recommended to carefully check the ingredients list before buying.
3. After drinking coffee always go to the toilet how do you?
Caffeine is a natural diuretic. After drinking coffee, some people will want to poop after a while and even have diarrhea. Indeed, some studies say that about 29% of people who drink coffee will have a laxative effect. But it is not clear whether this is the effect of caffeine or not. Because there are also studies that found that decaffeinated coffee also has a similar effect.
4. How to drink coffee insomnia?
Some friends like to drink coffee, but worry that they can not sleep at night. Caffeine in the human body metabolism time is almost 4-6 hours, but each person's physique is different, some friends may need more time to metabolize caffeine. At this time if you still want to drink coffee, we recommend that you try decaffeinated coffee. The caffeine content is low and you can still enjoy coffee at the same time.
