Is Caffeine Bad For You?

Is caffeine bad for you? The answer is a varied pack of tales and data. 

If you are a regular caffeine consumer. You will have fun finding out facts about caffeine, and the myths created through the years. 

In scientific terms, caffeine is a occurring, odorless. Bitter alkaloid found in coffee beans and other plant products, such as tea, yerba mate, and cocoa.

In humans, caffeine targets the central nervous system. And is the most consumed psychoactive drug (affecting consciousness) in the world. And one of the few substances whose consumption is legal. 

It’s a psychoactive drug. Because it stimulates the central nervous system and the autonomic nervous system.

That’s why people like caffeine—it can block the receptors that make you feel tired and boost your ability to focus. 

A six-ounce cup of coffee has about 100 to 200 milligrams of caffeine.

How Much Caffeine is in a Coffee Bean?

Despite what you may have heard. Roast doesn’t bear how much caffeine is in a coffee bean, because caffeine is neither created nor destroyed during the roasting process.

Bean to bean. The caffeine content is stable regardless of the roast level. What can affect the caffeine content of your cup is twofold:

•Species/Varietal. Robusta has about twice as much caffeine as arabica. Arabica beans have about 100 milligrams per six-ounce cup, and robusta beans have closer to 200 milligrams per six-ounce cup.

The level of caffeine can also vary among arabica plants depending on the varietal. But the differences aren’t all that significant.  

•Roast level. What? I just said roast doesn’t matter! It doesn’t on a bean-to-bean level. But you must take weight into consideration. 

Lighter beans. Weigh more than darker beans. A pound of dark roast coffee can have about 90 more beans in it. Than a pound of light roast coffee. 

Therefore. if you measure your beans by weight. A 20-gram dose of dark-roast beans. Would have more caffeine than a 20-gram dose of light-roast beans. But. Only because there would be more beans in the dose.

On the flip side, light beans are smaller than dark beans. As they don’t expand as much during the roasting process.

If you measure your coffee in scoops. There will be more light beans per scoop than dark beans. Which means. There will be more caffeine in your light-roast cup than your dark-roast cup.

In its natural form. Caffeine is a pesticide that kills or paralyses certain insects and prevents other plants from growing too close to the host plant.

Tea leaves or ground coffee meet the boiling water and extraction takes place. And produces flavors and aroma, and creates unique drinks such as tea or coffee.

This is the most popular question from readers, and any discussion about caffeine.

The simple answer is yes – caffeine is an addictive substance. 

Because it affects the central nervous system. Its continuous use causes the physical dependence. 

Withdrawal symptoms last from two to nine days and include: Headaches, fatigue, irritability, trouble concentrating, anxiety, and sometimes a depressed mood.

I base the more complicated answer on the addictive substance definition. 

Most times, the definition should include the threat to the health, social, and economic integrity of the addicted person. As happens with alcohol or heroin addictions. 

As a whole. caffeine does not meet this criterion. So those who accept this definition. Do not consider it an addictive substance.

The more involved answer is that each person has a different sensitivity and resistance to many substances, including caffeine. 

Several of us, could drink a cup of coffee at ten at night and will not affect the quality of our sleep. And the speed at which we fall asleep.

While for others. A cup of coffee at such an hour will ruin the night’s sleep.

The situation is even the opposite. Studies indicate that caffeine’s reasonable consumption leads to a reduced risk of developing quite a few diseases. Including cancers and type 2 diabetes.

The complicated answer is that studies present a general and statistical picture of the link between certain diseases and caffeine.

Still. As I have already mentioned, there are people with caffeine sensitivity, and there are always exceptions.

Is It Diuretic?

Simple answer: No. Contrary to popular belief, no established link exists between moderate coffee consumption and heart disease or high blood pressure. 

There is no evidence that caffeine affects or inhibits the growth of children.

Consumption of caffeine in reasonable amounts, does not cause adverse effects in most people. And even results in a positive impact.
