What is Caffeine?

Caffeine (also known as 1,3,7-trimethylxanthine) is a natural stimulant commonly found in tea, coffee, and cocoa.

What is Caffeine?

According to the US Food & Drug Administration, caffeine is considered a drug because it causes many neurological effects and can cause a mild dependence when used.

Currently, 80% of the world’s population consumes caffeine every day, even increasing to 85-90% of adults in America.

How does caffeine work?

If you’ve ever used caffeine, you’ve probably experienced feelings like increased concentration, increased alertness and can sometimes cause restlessness and anxiety. So why does caffeine do all this?

Caffeine works mainly in the central nervous system (brain and spinal cord). Their job is to interfere with the effects of adenosine. Adenosine is a compound produced by the body to perform a variety of functions.

One of these is acting as a neurotransmitter (a chemical that helps transmit information between nerve cells). When adenosine binds to adenosine receptors (receptors), they emit a sleep signal.

How does caffeine work?

When we use caffeine, caffeine will bind to adenosine receptors and prevent adenosine molecules from doing their job. In this way, caffeine increases alertness and fights drowsiness.

To make it easy to understand, you can imagine the following: if you put a key in a lock “not of the same type” then this will not only fail to unlock the lock but also block the “same type” key from performing the task its case.

The working principle of caffeine doesn’t stop there. According to research, caffeine also helps stimulate the release of neurotransmitters such as dopamine, epinephrine (also known as adrenaline), and norepinephrine (noradrenaline).

These are substances that help increase alertness, focus, and energy production. Unlike other substances, caffeine not only indirectly produces neurotransmitters, they act directly on the adrenal glands (adrenal glands).

This means that caffeine directly activates the body’s “fight or flight” mechanism. A physiological response occurs when we are in danger or threat.

When we use caffeine, they tend to act pretty quickly. For example, the amount of caffeine in a cup of coffee only takes 20 minutes to absorb into the bloodstream and takes about 1 hour to fully exert its effects.

Caffeinated foods

Caffeine is commonly found in nuts or leaves. From these natural sources people produce caffeinated foods and beverages. Here are the amounts of caffeine in 240 ml of some popular beverages:

Caffeinated foods

The first is espresso coffee (240-720 mg), black coffee (102–200 mg) energy drinks (50–160 mg), tea drinks (40–120 mg), carbonated soft drinks (20–40 mg). ), decaffeinated coffee (3-12 mg), cocoa drink (2-7 mg), chocolate milk (2-7 mg) …

In addition to beverages, many foods also contain caffeine. For example, while 28 grams of chocolate milk has only 1–15 mg of caffeine, 28 grams of dark chocolate has 5–35 mg.

In addition, caffeine can also be found in cold medicines. allergy medicine, pain relief.

Not only that, but caffeine is also a common ingredient in fat loss supplements. In conclusion, caffeine is commonly found in chocolate, tea, coffee, carbonated soft drinks, and energy drinks.

improve brain function?

From there, it helps to improve mood and brain function. In one study, when participants consumed 37.5–450 mg of caffeine, their alertness, short-term memory, and reaction time (of the brain) improved.

Not only that, one study found that drinking 2 to 3 cups of caffeinated coffee per day reduced the risk of suicide by 45%. Meanwhile, another study found that caffeine consumption reduced the risk of depression by 13%.

On the other hand, from a mood improvement perspective, the use of more caffeine is not necessarily better.

One study found that having a second cup of coffee had no benefit unless they were consumed in the first isolation for at least 8 hours.

Besides, many studies have also demonstrated that drinking 3-5 cups of coffee a day can help reduce the risk of brain diseases like Alzheimer’s and Parkinson’s by 28-60%.

In conclusion, caffeine intake can help improve mood, decrease the likelihood of depression, stimulate brain function and protect them from diseases like Alzheimer’s and Parkinson’s.

Can caffeine help with fat loss?

Thanks to its ability to stimulate the central nervous system, caffeine can help increase the metabolic rate by 11% and burn fat by 13% more. And this has been proven in quite a few studies.

increase the metabolic rate

Not only that but consuming 300 mg of caffeine per day can also help you burn 79 more calories per day. These calories seem quite small, but they are the equivalent of the extra calories that cause weight gain (1 kg) annually in the US.

However, in a 12-year study of caffeine and weight gain, coffee users lost only 0.4-0.5 kg after follow-up. In conclusion, caffeine can boost metabolism and lose fat, but the effect is small if maintained over a long period.

In a study by the University Of Birmingham, results showed that consuming 5 mg of caffeine per kilogram of body weight improved endurance training by 5 percent.

In this study, caffeine was consumed 1 hour before exercise. Also, in another study, scientists found that a low dose (3 mg / kg of body weight) is still enough for us to benefit from caffeine.

What’s more, many studies report that caffeine has similar benefits in combination sports, intense exercise, resistance training … Besides, caffeine also helps reduce the feeling of exertion during exercise. practice down 5.6%.

Can caffeine help prevent disease?

In addition, some studies show that drinking 2 to 4 cups of coffee or green tea per day reduces the risk of stroke (stroke) by 14-20%. In some people, caffeine use can cause a slight increase in blood pressure.

However, this effect is quite small, only about 3–4 mmHg (Millimeter of mercury – unit pressure). And they tend to decrease gradually for most people when they regularly consume coffee.

Not only that, caffeine also works to help fight diabetes. Research shows that people who drink a lot of coffee have a 29% lower risk of type 2 diabetes.

Likewise, people who consume caffeine also reduce their risk of the disease by about 30%. The study’s authors found that the risk decreased by between 12-14% for every 200 mg of caffeine consumed by the participants.

In this study, there is something very interesting. That is, the consumption of decaffeinated coffee still reduces the risk of diabetes by 21%. Through this, we can see that in addition to caffeine, coffee still has a number of other compounds that help prevent diabetes.

In conclusion, caffeinated beverages like tea and coffee may reduce the risk of heart disease and type 2 diabetes. .

Other benefits of caffeine

In addition to helping with fat loss and exercise support, caffeine has a ton of other benefits for the body as well. One of those benefits is its ability to protect the liver.

Not only that, consuming 3 cups of coffee per day for 3 weeks can increase the number and activity of beneficial bacteria in the gut. Note that among the studies above, some of the benefits may be due to other substances in coffee, not just caffeine.

Is caffeine safe or not?

In general, caffeine is a fairly safe substance. However, they are addictive and some people’s genes may make them more susceptible to this problem. Not only that, according to research, caffeine can also cause a number of side effects.

What’s more, caffeine can easily cross the placenta. From there, it can increase the risk of miscarriage or cause underweight in the newborn. For this reason, pregnant women need to limit their caffeine intake.

Besides, caffeine can also react with some drugs. Therefore, people using the muscle relaxer Zanaflex or the antidepressant Luvox should avoid caffeine, because they increase the effects of the drug.

Dosage when using caffeine

Both the US Department of Agriculture (USDA) and the European Food Safety Authority (EFSA) recommend 400 mg of caffeine per day as safe.

This amount of caffeine will be equivalent to 2-4 cups of coffee per day. On the other hand, taking 500 mg of caffeine in a single dose causes an overdose and can lead to death. Therefore, many studies recommend consuming only 200 mg of caffeine per dose.

In addition, according to the American College of Obstetricians and Gynecologists, pregnant women should limit their daily caffeine intake to 200 mg.
