Coffee

Coffee is a beverage prepare from roasted coffee beans, which are obtained from the Coffea plant. Coffee has two main species: Arabica and Robusta. Robusta coffee packs 50% more caffeine, and a sharp bitter flavor. This is one reason why Arabica coffee is the more desirable of the two, as it possesses a smoother taste and enjoyable flavor characteristics.

A regular cup of coffee contains around 2.4 calories, and absolutely no fat and sugar. Coffee contains a number of micronutrients such as potassium, magnesium and niacin. The type of water used in preparation of coffee can often influence its micronutrient content, and this is especially true for black coffee.

Health Benefits of Coffee

Mentioned below are the best health benefits of Coffee
Health Benefits of Coffee

Boosts energy levels

Coffee contains extremely high amounts of a compound called caffeine, which is the most widely consumed psychoactive compound in the world. When you consume coffee, the caffeine is absorbed into the bloodstream. Once in the brain, caffeine blocks an inhibitory neurotransmitter called Adenosine. When that happens, the amount of other neurotransmitters like norepinephrine and dopamine actually increases, leading to enhanced firing of neurons. This leads to improved energy levels, mood, reaction times, and overall cognitive function.

Can aid in weight loss

Coffee has numerous health benefits, and helping with weight loss is one of them. There is a reason caffeine is found in almost every fat burning supplement. Caffeine is one of the very few natural substances that aid weight loss efforts. Caffeine can boost the body’s metabolic rate by around 10%, thus helping the body burn fat faster.

Improves physical performance

Caffeine stimulates the nervous system, causing it to send signals to the fat cells to break down body fat. Additionally, caffeine also increases adrenaline levels in the body. Adrenaline is the ‘fight or flight’ hormone, which, when released, readies the body for physical exertion. When this happens, fatty acids are released from the fat tissues, thus making them available as furl. So, it is advisable to drink coffee before activities that require physical exertion.

Coffee can lower risk of diabetes

Type 2 diabetes is currently a huge problem which affects millions of people all over the globe. Diabetes is characterized by elevated blood sugars in the context of insulin resistance or an inability to secrete insulin. Studies have shown that people who drink coffee on a daily basis have a reduced risk of developing type 2 diabetes.

Prevents onset of diseases such as Alzheimer’s and Parkinson’s

Alzheimer’s and Parkinson’s are two very common neurodegenerative diseases that affect older people, and are still incurable. Studies have proved that drinking coffee regularly can reduce the risk of developing these diseases. This is because the caffeine in coffee helps keep the brain functioning well and keeps cognitive functioning at the maximum level.

Is very beneficial for the liver

The liver is one of the most vital organs of the body, and keeping it in top shape is very important. Regular consumption of coffee has been proved to help prevent disease such as liver cancer, fatty liver disease, alcoholic cirrhosis and hepatitis. People who drink 4 or more cups of black coffee everyday have 80 per cent lower chances of developing any liver disease. Coffee helps by lowering the level of harmful liver enzymes in the blood.

Helps cleanse the stomach

Coffee is a diuretic beverage, which means that it increases urine output and frequency of urination. Regular consumption of coffee ensures that the toxins and bacteria in your system are easily and quickly flushed out in the form of urine. This helps cleanse the stomach and keep it free from infections.

Reduces depression

Too much work pressure and tension can lead to depression and stress which in turn can cause many serious health issues. Drinking coffee regularly can help counteract depression. Coffee stimulates the central nervous system and increases the production of dopamine, serotonin, and noradrenaline, important neurotransmitters that elevate the mood, thus preventing depression.

Reduces risk of cancer

Coffee contains certain compounds which have been proved to prevent certain types of cancer such as breast cancer liver cancer colon cancer and rectal cancer. The main reason behind this is that coffee is extremely rich in anti-inflammatory compounds. These anti-inflammatory compounds help prevent tumors, thus protecting against cancer.

Prevents gout

Research has shown that regular consumption of coffee can reduce the risk of developing diseases such as gout. The powerful antioxidants present in coffee reduces the risk of developing gout by decreasing the level of insulin and uric acid in the body. Even in people who are already suffering from gout, drinking coffee can help alleviates its symptoms.

Uses of Coffee

The most common use of drinking coffee is to help relieve physical and mental fatigue, and to increase mental alertness. Most of us swear by a cup or two of coffee every day in the mornings. Coffee contains caffeine in very high amounts, and caffeine has the capability to increase alertness and boost mental clear thinking. Additionally, coffee can be used to prevent diseases such as Parkinson’s, gastrointestinal cancer, Type 2 diabetes, breast cancer and lung cancer.

Side-Effects & Allergies of Coffee

Coffee contains high amounts of caffeine, as a result of which it can cause side effects such as insomnia, nervousness and restlessness, stomach upset, nausea, vomiting, and increases heart rate. Consuming large amounts of coffee might also cause headache, anxiety, agitation, ringing in the ears, and palpitations. Additionally, drinking coffee on an empty stomach can be harmful, because coffee stimulates the production of hydrochloric acid, which is an acid that should only be produced when meals need to be digested. If your body has to make HCL more often in response to regular cups of coffee, it may have difficulty producing enough to deal with a large meal.

Cultivation of Coffee

The Coffea plant is native to tropical Africa and Madagascar, and the modern version of roasted coffee has its origins in Arabia. During the 13th century, coffee was extremely popular with the Muslim community for its stimulant powers, which proved useful during long prayer sessions. In 1616, the Dutch founded the first European-owned coffee estate in Sri Lanka, then Ceylon, then Java in 1696. The French began growing coffee in the Caribbean, followed by the Spanish in Central America and the Portuguese in Brazil. European coffee houses sprang up in Italy and later France, where they reached a new level of popularity. Soon after, coffee plants reached the US, and by the late 1800s, coffee had become a worldwide community. The coffee plant needs ample rainfall to grow, and its temperature requirements vary depending on its type. Coffee crops grow very well in higher altitudes, but they are very vulnerable to frost. Coffee plants can grow on a wide range of soils, but sandy loam soil is ideal for its cultivation.

Now being hailed as the elixir of life, coffee is said to improve cell regeneration besides increasing immunity and stamina, thereby increasing life expectancy for compulsive caffeine addicts. That does not mean indulging in an indiscriminate drinking of coffee. The consumption must naturally be kept in check as well; the harmful side effects of drinking excess coffee still stand.

The fact that coffee is the most delicious beverage and preferred by young and old alike in all its forms and shapes, makes it even better.

  1. Coffee however is also endowed with the power to prevent certain chronic diseases that affect people in their advanced age- Parkinson's disease, Diabetes, prostate cancer, liver malfunction, even dementia and Alzheimer's.
  2. It also helps in easing movement problems common in old age. This is the primary reason why coffee enables you to lead a longer life.
  3. Another factor working in favor of coffee is its beans consist of some extremely useful elements, including antioxidants and antibacterial substances that help in fighting viral pathogens.
  4. Besides increasing life span, well up to hundred years of age, coffee is also reputed to decrease the risk of premature death in adults by a total of 8 percent. Drinking coffee regularly is therefore a good habit to inculcate for more than one reason.

Usually coffee drinkers are also smokers. If you want to reap the full benefits of coffee, you must quit smoking and use of other harmful substances.

Coffee Consumption Reduces Mortality
===============================
The largest prospective cohort study evaluated the impact of coffee consumption on all?cause mortality and involved 229,000 men and 173,000 women, who were followed for up to 13 years (N Engl J Med 2012;366:1891).

After adjustment for smoking status and other potential confounders, associations between coffee consumption (either caffeinated or decaffeinated) and reduced all?cause mortality were evident at relatively low levels of consumption (2 to 3 cups/day).

Compared to non?coffee drinkers, the risk of all?cause mortality among men and women who consumed 2 to 3 cups of coffee daily was 0.90 and 0.87.

The apparent benefit of coffee was similar for individuals with high levels of coffee consumption, including those who drank six or more cups of coffee per day.

Coffee Drinking Is Good For You?

It appears that, in large populations of people, drinking coffee may (on average) confer health benefits. In particular, the risk of cardiac death and of overall mortality appears to be lower in coffee drinkers, with the optimal benefits seen in people who drink 3 - 4 cups per day. Whether caffeine has anything to do with such health benefits is not entirely known. Coffee contains a host of active substances aside from caffeine - substances that are thought to act as antioxidants and anti-inflammatory agents, for instance - that may be contributing to this beneficial effect.

Epidemiological studies like this one, no matter how well they are performed, cannot possibly answer whether a specific individual will realize health benefits from coffee drinking. They can only tell us about the average response, across a large population.

We know that some individuals (probably determined by their genetic makeup) are particularly sensitive to caffeine, and may suffer severe sleep deprivation, jitteriness, or palpitations after drinking coffee (or any other caffeine-containing food or medication). We also know that caffeine sensitivity can change dramatically at various periods in one?s life (especially during pregnancy, when sensitivity to caffeine almost always increases). Drinking coffee is clearly not a good idea for everyone.

As a general rule, then, coffee drinking appears to have health benefits. But at least until routine genetic testing is available that might tell us about our own individual sensitivity to caffeine, whether coffee drinking is a good idea for us is something we?re just going to have to figure out for ourselves.

Read all about coffee and your heart.

Cardiac mortality: Compared to people who drank no coffee, people who drank one cup per day experienced an 11% reduction in cardiac mortality.This mortality
benefit ?peaked? (at about 20%) for people who drank 3 - 4 cups per day, and then began to diminish as the amount of coffee consumption increased beyond that level.
Cancer mortality: Several reports over the years have suggested that coffee might reduce the risk of certain cancers. In this large study, however, there was no difference in cancer mortality between people who drank no coffee, and people who drank from 1 to 6 cups of coffee per day.

Overall mortality: Compared to people who drank no coffee, coffee drinkers had a reduced mortality rate. Again, this mortality benefit seemed to peak at between 3 - 4 cups per day (at about a 15% reduction in mortality).
