All you need to know about coffee


Drinking of Coffee is one of the oldest habits on earth. Its story began over a thousand years ago after goat shepherds in Ethiopia (a mountainous country in east Africa) noticed how lively and playful their goats became after feeding on a particular tall plant with small red fruits and so they went for it themselves!

The earliest recognized proof of knowledge of coffee – the tree, its red fruit berries and the brown bean seeds within, its consumption as food and brew – is traced back to the Sufi monasteries of Yamen in the 15th century A.D. Today, coffee is the second most traded product in the world. It is to be found in almost every store, business establishment or home. People drink coffee several times each day, all week, all month, for the whole year.

Coffee makes a complex beverage with over a thousand different compounds in it, most good to human health, some bad. The best-known ingredient of coffee is caffeine. the most widely consumed psychoactive substance on earth. Given these facts, a lot of research has been done on the subject of coffee’s health benefits to the body. Unfortunately, due to the vast array of compounds present in coffee, a lot of conflicting information have been set forth by researchers in the past.



In the past, coffee was blamed for too many ills from madness to stunted growth and heart disease. But new finding shows that most of these assumptions about coffee were groundless.


PEOPLE ALWAYS ASK……

How does coffee really work? Is coffee really good for the body? Does it really cause cancer and heart diseases? What are the advantages and disadvantages of drinking coffee? How many cups is it safe to consume per day?

HOW COFFEE WORKS

Present in your brain is the enzyme Adenosine, which only likes to pair up with receptors. When this union is accomplished, you get all sleepy. Once caffeine shows up in the vicinity, it attaches itself to the receptors instead, making it impossible for the Adenosine to do so. Your pituitary glands see this situation and think there is an emergency, so signals the adrenal glands to produce even more adrenaline. 

Also increased are your dopamine levels and thus you get your boost!

Technically speaking, coffee doesn’t give you a boost but tricks your body into doing just that.

12 ADVANTAGES OF DRINKING COFFEE



1. Long life
Researchers from Harvard University say, drinking just 3 cups of coffee a day (even decaf) could actually help you live longer.

Yet another study showed that the overall risk of premature death in coffee drinkers is 25% lower than in non-coffee drinkers! Coffee contains over 1000 compounds, several of which come into play here. 

2. Parkinson’s disease
Research has shown that regular consumption of coffee does have certain brain disease prevention benefits. The risk of Parkinson's disease is cut down by up to 25 % as coffee causes favorable activity in the part of the brain affected by Parkinson’s,

3. Diabetes
Regular intake of coffee (under 3 cups per day) significantly lowers the risks of type 2 diabetes. Caffeine reduces the body’s insulin sensitivity and weakens glucose tolerance, this leads to a reduction in the risks of type 2 diabetes.

4. Liver Disease
The risks of different kinds of Liver Diseases, particularly liver cancer, is reduced markedly by coffee intake.



5. Mind and Depression
Regular coffee drinking enhances (improves) cognitive function and significantly diminishes the risk of depression. Put simply, coffee enlivens (brightens) your mood, fights depression, and thereby, lessens the risk of committing suicide. How? The central nervous system is stimulated by caffeine, leading to a boost in the production of neurotransmitters such as dopamine, noradrenaline, and serotonin, which improve your mood. Just 2 cups of coffee per day reduces the risk of suicide by up to 50 %.

6. Performance Booster
This is one reason we take coffee. 
Regardless of the funny way it gets the job done, coffee does boost body performance. Drink just one cup of black coffee an hour before going on a workout and your overall performance jumps by at least 11-12%. Caffeine triggers an increase in your blood’s adrenaline levels, pumping you up perfectly for action. Adrenaline is your body’s “action or fight” hormone – it conditions you quickly for physical action or exertion.

7. Weight Loss & Blood Sugar Regulation
Coffee, with its high potassium and magnesium content, helps with weight loss. Coffee stimulates the body’s ability to use up insulin readily, thus regulating blood sugar levels. Coffee also has the strange ability to reduce your craving for snacks and sugary treats.

In addition, the presence of coffee in your bloodstream triggers the burning up of excess fat at every opportunity. Caffeine even helps cells break down complex body fat for use as fuel during vigorous physical exertions. This also helps with weight loss.

8. Concentration
Drinking less than 6 cups of coffee a day is considered moderate and healthy caffeine intake. It improves mental clarity and alertness.

9. Cancers.
Research shows that coffee significantly lowers the risk of developing endometrial cancer in women by up to 25 % and prostate cancer in men by about 20 %. Subjects in this test group consumed just 4 cups of coffee per day. Caffeine, in particular, can stop the development of basal cell carcinoma, which is the most common type of skin cancer.



10. Heart Diseases and stroke.
No medical study has ever linked coffee to an increased risk of heart disease or stroke. The opposite is actually the case with moderate intake of coffee; it significantly lowers overall mortality in people, even cardiovascular mortality. In other words, you can actually cut back the risks of heart attack, stroke and sudden death by just drinking coffee.

This quality of coffee is partly due to its high antioxidant content and the fact that it has the ability to reduce clogging of the arteries.

11. Anti-Aging
Coffee is rich in antioxidants, which are powerful substances that attack free radicals and toxins within the body. Free radicals and toxins are the number one causes of premature aging in humans.

12. Brain
Very regular consumption of coffee, which results in high levels of caffeine in your bloodstream, greatly lowers the risk of developing diseases that induce degeneration of brains cells such as Parkinson’s diseases, Alzheimer’s diseases, Multiple Sclerosis, and dementia. More research is required on the matter.though.


8 DISADVANTAGES OF DRINKING COFFEE



1. Death
Consuming up to 80-100 cups (a staggering 23 liters) in a short session will kill you. This amounts to 10-13 grams of pure caffeine in your bloodstream. That's a lethal. It’s not just the caffeine, though, no one can stand such a high intake of liquid – rapid vomiting will take effect long before the lethal limit is reached. Even the drinking 23 liters of very clean water in a short session can kill you.

2. High-Risk Behavior
Heavy coffee intake tends to induce high-risk behaviors, such as drinking, smoking and physical inactivity. Your body's willingness to engage in physical exercise decreases markedly. Studies have shown that these habits are all too common among heavy drinkers of coffee.

3.High Toxic Levels
A lot of harmful impurities are present in bad quality coffee. Illnesses, headaches or bad moods can result from just drinking bad coffee. Over-ripened coffee beans are the main cause of bad coffee. Just one single bean can ruin a pile. Stick to high-quality coffee and you will be fine.

4. Not For Kids
Coffee doesn’t really harm kids but will dramatically increase their rate of bedwetting.

5. Extreme Restlessness And Sleeplessness (Insomnia)
Can’t sleep at night after drinking a cup of coffee too close to bedtime? Caffeine at work!
Anything over 400 milligrams of caffeine, (roughly the amount gotten from taking 4 cups of coffee) is just too much for a healthy person to sleep on. Caffeine-sensitive people, be extra careful. Interestingly, nature has assigned to every single person a specific amount of caffeine that is perfectly safe for consumption and this is written into the DNA. Once over your specified limit, you begin to feel odd. So people, watch your coffee intake and note how it makes you feel.

For a good night’s sleep, avoid drinking coffee for at least seven hours before bedtime.



6. Coffee and Pregnancy
Are you pregnant? If, yes, do not drink more than 1 cup of coffee per day. Although studies on the exact effects of coffee on unborn babies (fetus) is a subject of endless debate among experts, one thing is certain: drinking coffee when pregnant, results in caffeine reaching the unborn baby (fetus), a developing creature that is highly sensitive to caffeine by nature. If you do not want to cause health complications in your baby, stir clear of coffee completely. If you are a heavy drinker, one cup a day is your limit once pregnant.

7. Cholesterol
People with high cholesterol levels should stir clear of unfiltered coffee. kahweol and Cafestol are two major ingredients of coffee beans that spike LDL cholesterol levels (bad cholesterol). The process of filtering coffee removes most of the LDL ingredients, but kahweol and cafestol are still to be found in some kinds of coffee -- Espresso, French press, Turkish coffee, and Scandinavian coffee (Scandinavian 'style' cooked coffee).

Under normal circumstance, LDL cholesterol intake from one single cup of unfiltered coffee or espresso is so small that people with healthy cholesterol levels are not affected by it in any way, hence the allowance for up to 6 cups a day. Kahweol and Cafestol are not entirely bad, though. New studies show that they can be beneficial to people with liver problems and early-stage cancer.

8. Genetic Flaws
There are people with a kind of genetic mutation that reduces the rate at which caffeine breakdown occurs in the body. For these group of people, just 2 cups of coffee a day can heighten the risk of heart disease.
Generally speaking, the speed at which your body metabolizes coffee affects your health.



CONCLUSION

Stir clear of coffee if you’ve got high cholesterol, caffeine sensitivity, or are pregnant. If you are a parent, pay careful attention to coffee drinking and keep it away from your kids.  

If you are a healthy adult, fine. Stick to healthy consumption of coffee (1-6 cups per day) and it will do you much good. Coffee will keep you safe from chronic illnesses and diseases, boost your muscles and mind, and help you lose weight. Stick to toxin-free, brew it carefully, and enjoy. It is good for you!

POINTS TO BEAR IN MIND

*Coffee may have these many benefits, but other beverages, like milk and certain fruit juices, contain nutrients and vitamins that coffee doesn't. Again, adding things like sugar and cream to your coffee increases its fat and calories levels markedly (up to hundreds of calories depending on ingredients).



*Drinking up to 6 cups of coffee daily is good for you and will have no negative impact on health, say researchers from the Harvard School of Public Health. However, those researchers never gave the go-ahead to rampant coffee consumption. That research only involved very healthy men and women in their 40s - 50s, coffee consumption - moderate, with little milk or sugar.

WARNING! Do not go consuming sugary coffee in extra-large mugs and expect it to be good for you.
