Caffeine is one of coffee’s primary constituents with psychoactive activities. It’s part of a group of substances collectively referred to as methylxanthines. These alkaloids are well known for their ability to increase cognitive abilities, improve energy, enhance well-being, and increase arousal and alertness.

Studies demonstrating the effects of caffeine on neurotransmitters (chemicals that allow the cells of our nervous system to communicate) don’t always give us a realistic picture.

The dose used in neurochemical studies generally exceeds quantities ingested during normal everyday life.

Coffee, discovered by a shepherd in Ethiopia, is one of the most important beverages in Ethiopian society and in the world today.  Most studies support the benefits of drinking coffee in moderation.

It is true that every thing that is beneficial, when  exceeds a limit has disadvantages and severe consequences. A prescribed medicine can be poisonous if taken beyond the limit. Our body system might have a capacity limit on caffeine as it is a stimulant agent,  to properly utilize and function beyond which it creates extreme excitement and nervousness, the opposite effect of why we drink coffee in the first place. 

I always see similar acquisitions and support in drinking caffeine and wine where such organizations you mentioned make. In both cases, moderation is the optimal way of consuming wine and caffeine for a desired result, either to enjoyment or excitement.  

Dear friend

I would like to add some spice to the above answer.

Coffee is beneficial to our health, but let us see how.

Caffeine is chemical compound (drug) that affects our nervous system. Its just like any narcotics drugs that we see around.

You might have seen so many people around you that they wont start their day without having coffee. Their body biological clock starts with coffee (so much dependent on coffee). Its like having cigarettes in a day.

just like alcohol is having some positive effect on the metabolic process, provided that  it is taken in limited quantity. Likewise too much coffee may spoil our metabolic process.

Our brain is highly complex organ of our body. If you go deeper the way the brain neuron cells interact, you will see that the chemical reactions that takes place is highly complex in nature. The essential amino acids required for the information processing may be affected if any kind of drugs or narcotic products are consumed.

There is even more deeper explanation, but I think it is sufficient for the time being, which I am not writing for want of space.

I hope this helps you.

Best regards

I take green tea and chocolate Horlicks. I have a daily habit of starting with a hot tea in the morning, and a cup of chocolate Horlicks in the night time. If I don't take them, my normal activities are not disturbed. I was told that green tea too mild  or no caffeine at all, and I posted a query related to green tea yesterday.

When I was at USA, I used to take Starbucks Coffee, but after returning to India, I stopped taking Coffee.

Of course, people have different taste, and we proceed with our likes and dislikes in life. Have a great day.

This is a good question: I think that we should consume different kinds of drinks and not take always the same drinks; this leads to consume different healthy ingredients and do not consume unhealthy ingredients in dangerous amounts.

Thank you for all your posts concerning the use of Caffeine. I would like to expand the question and ask whether any research exists on the long-lasting effects of drinking a lot of coffee. Is there a chance of getting Thrombosis?

Hi,

Here is a nice research article, In conclusion it says

"In this large prospective study, coffee consumption was inversely associated with

total and cause-specific mortality. Whether this was a causal or associational finding

cannot be determined from our data."

Big recommend to both colleagues Mahfuz Judeh and Ljubomir Jacić

There are many another agents that affect our health times more than caffeine.

Dear Colleague,

I think it is best to focus light on many other recent medical problems at least to contribute in solving such critical cases, for example, Ebola virus, Zika virus, ..etc.

The health costs of physical inactivity are substantial. Physical inactivity is associated with reduced lifespan and increased risk of disability, cardiovascular disease, hypertension, diabetes, certain types of cancer, and dementia. On the hand physical activity prevents and manages obesity, improves mental health, and increases quality of life for people affected by a number of chronic conditions. This list of benefits gives physical activity a strong case in being called a “miracle cure”.

Why then does less than half of the EU adult population meet the current physical activity guidelines and even less in the USA? In my opinion we have never payed enough attention to the core psychobiological reason for physical inactivity: humans are inherently “lazy.” By lazy I mean that humans have a natural tendency to avoid effort, a principle of human behaviour well established since 1943. Unfortunately, even moderate-intensity physical activity requires considerable effort compared to sedentary leisure-time activities like watching TV or surfing the internet. So it is not surprising that most people, when faced with daily decisions like “Do I go out for a walk/run or do I sit on my sofa watching television?” choose the latter.

The scope of the problem encouraged me to make a proposal late last month. In my article, I suggested the use of psychoactive drugs like caffeine or methylphenidate and modafinil to reduce perception of effort and, thus, facilitate physical activity behaviour. This novel strategy has been described as “doping for lazy people” because caffeine was included in the World Anti-Doping Agency (WADA) list of prohibited substances until 2004, and both methylphenidate and modafinil are still banned. In addition to these stimulants, I also propose the use of psychoactive drugs to enhance the so-called “runner’s high” because, if enhanced, the positive feelings experienced after exercise may provide immediate rewards which are more motivational than delayed and probabilistic rewards (e.g. a reduced risk of developing coronary heart disease in 20-years)...

Caffeine or coffee is an alkaline substance from the group of zantines and is classified as psychotropic drugs from the group of stimulants. Caffeine acts as an alarm for the central nervous system in humans, temporarily renewing activity. Tea, Arabic coffee and cola are the most important sources of caffeine. Human consumption of caffeine since the Stone Age has been known by chewing some seeds and leaves of some plants because of the harsh life they lived to relieve the effects of fatigue as well as motivating them to awareness and permanent orgasm. According to a Chinese folk legend, the discovery of caffeine is due to the Chinese Emperor Chenyong (reputed to rule in 3000 BC). It was accidentally discovered, as some leaves fell in the boiling water and smelled of it. Coffee dates back to the ninth century BC, where its granules were used in Africa in the barter system. The definition of caffeine is a sub-alkaline substance known as bitter white. There are many compounds that fall under sub-alkaline compounds, including methylxanthine, which is composed of three compounds: caffeine, theophylline, and theobromine found in coffee and tea. And seeds of some plants, as they are naturally pesticides that paralyze and kill some insects that feed on these plants, as discovered in 1821 by French pharmacies. That the world Balluteh, noting that the drug was isolated from coffee. It also has chemical and biological effects in different proportions on humans. C8H10N4O2 The Benefits of Caffeine A scientific report from the National University of Singapore states that drinking a cup of tea is beneficial to the brain, slowing the deterioration of cells and keeping the mind sharp. The study, which lasted four years by scientists in Singapore, said tea has a long list of benefits. Singapore scientists have found that caffeine protects the brain cells from the accumulation of the destroyed protein over the years, keeping the brain strong. But they said the caffeine in tea is different from that in coffee, as it contains natural protein thiamine, which has the natural side effects of caffeine, such as high blood pressure, headaches and stress. A study team at Duke University Medical Center in North Carolina found a strong relationship between caffeine intake with meals and increased levels of sugar and insulin in patients with type 2 diabetes. diabetic. [Edit] The BBC broadcast on its website on July 20, 2004, the news of a study by the International School of Advanced Studies in Italy that caffeine can block the memory and remember some names. Students should be advised not to drink coffee, tea, coca, and other caffeine-containing substances, especially on exam days. [9] In addition, women, nursing mothers and pregnant women, in particular, must avoid coffee, tea and cola products in order to preserve the health of their pregnancies and the lives of their babies. [10] Many other damages [edit] Eating caffeine causes anxiety, headache and insomnia. It also causes addiction. Although coffee has no nutritional value and no calories, the caffeine makes it lose a lot of minerals and vitamins through the urine and interferes with the absorption of nutrients. Caffeine in coffee, tea and cola makes the kidneys leak with urine a number of essential vitamins, calcium, iron, potassium, magnesium and trace elements and this is a nutritional loss to the body. And women who over-tea, coffee and cola, then lack of bone density and osteoporosis osteoporosis, especially after menopause and even if the treatment of calcium heavily. Caffeine causes anemia, debilitation and depression. The pancreas is exhausted and damaged as it makes the liver excrete glucose sugar and this raises the blood rate and secrete the pancreas more insulin to store excess sugar as a fat person feels the decline of energy. He turned to another cup of coffee. The presence of caffeine with carbohydrates increases the rate of caffeine found in many plant species, as high rates are found in nutrient plants, and high levels of caffeine are found in the soil around the coffee beans. There are common sources of caffeine, coffee and tea found in chocolate, such as redbull and soft drinks such as cola, as well as some medications for treating respiratory disorders. In 1819, the German chemist Ferdinandong isolated relatively a quantity of caffeine for the first time. In 1821, All the caffeine was isolated by French chemist Jean-Pierre and the duo from French pharmacies Pierre Joseph Blutte, Joseph and Joseph Caventobenem. According to Swedish chemist Berzelius, the Swedish chemist also said that French chemists had made discoveries independently of the knowledge of German chemist Rong Oggere . The health effects of caffeine The global consumption of caffeine is estimated at 120,000 tons per year, making it the world's most popular psychoactive substance. This does not amount to serving one of the drinks that contains caffeine per person every day. Caffeine is the central nervous system and also stimulant, it is used recreationally and medically to reduce physical fatigue and restore mental alertness when tired or unusual drowsiness occurs. Caffeine and other methylxanthine derivatives are also used on newborns to treat arrhythmia and correct breathing cessation. Caffeine stimulates the central nervous system first at higher levels, resulting in increased vigilance, faster flow and more pronounced thought

Caffeine acts as a central nervous system stimulant. When it reaches your brain, the most noticeable effect is alertness. You'll feel more awake and less tired, so it's a common ingredient in medications to treat or manage drowsiness, headaches, and migraines. ... For example, too much caffeine can give you headaches.
