Answer: Decaf coffee is not diuretic

10 Questions That Everyone Asks

The coffee lovers, when getting this answer, asked a lot of knowledge-based questions. From their queries, I listed 8 of the best questions. These answers will help you to know: why decaf coffee is not diuretic?

1. What is decaf coffee, and how is it made?

Let’s start the answer by breaking the word “decaf coffee.” It means decaffeinated coffee – a short version. The coffee has the least amount of caffeine than regular coffee. Here is a fact about regular coffee.

  • A regular cup of coffee contains 95mg caffeine.

It’s huge, right? Let me share another unknown fact:

  •  A cup of decaf coffee has only 2 to 7 mg caffeine.

Can you see a significant difference? Yes, now it will be easier for me to explain the decaf coffee.

Decaf coffee

When the coffee beans are harvested, they are divided into many sections. Some of the sections have high caffeine, or, low even least! And decaf is the least one.

The bean producer extracts all the caffeine from the coffee beans for decaffeination. It takes 9 to 10 hours to remove 97% of caffeine. Now how do they perform the process?

2. How is decaffeinated coffee made?

Well, the bean hunter follows four unique procedures to decaf the beans. Here is the process:

  • Indirect solvent process
  • Direct solvent process
  • Swiss water process
  • CO2 procedure

Indirect solvent process Direct solvent process Swiss water process CO2 procedure Indirect solvent process

The process starts by putting the seeds in boiling water. It extracts oils and flavor; then, the beans washed in a tank for 10 hours.

This high-end tank has a mix of methylene chloride. Methylene chloride removes the solvent and caffeine.

Next, the filtered beans are soaked in the first boiled water. This water has oil and flavor -so beans will reabsorb the elements. And this way, the decaf coffee takes birth.

Direct solvent process

The second one is the direct solvent procedure. It starts from boiling the beans for 30 minutes. Then, that coffee rinsed over and over for 10 hours in Methylene Chloride.

This chemical takes all the caffeine, which points to go for the next step. The next step is steaming the beans for removing all residual solvents.

When all the solvents are gone, the beans are ready. This process needs extra care for direct solvent applications.

Swiss water process

The next process is the Swiss water process. This is one of the natural processes that take less time to remove caffeine. It starts by putting the beans in a charcoal activated filter.

Before filtering the beans, coffee makers boil them in hot water to dissolve oil and flavor. This steaming process makes decaffeination faster.

In that process, the charcoal catches the caffeine molecule. It takes some time, but the process keeps the bean natural.

The natural beans then again put the warm water to absorb the flavor and oil. Doing this process over and over makes sure: it has the best coffee.

CO2 procedure

Kurt Zosel is the inventor of the CO2 process. The scientists believe that this is one new and useful process to decaf the beans. In fact, the coffee is not diuretic for an unbeatable making process. So, here is the process:

The CO2 procedure starts by soaking the beans in a hot water chamber. Then, it passed in a CO2 solvent. This solvent removes the caffeine and prepares it for the next step.

In the later step, makers remove the chemical from beans and ensure the flavor, oil, and essential elements. Finally, the coffee is ready to brew and sip.

Now, the explanation leads to the next step.

3. Is decaf coffee really a diuretic?

Yes, this is the step where we are going to share another proven fact. This fact will assure you why decaf coffee is not diuretic.

In research, the scientist found that: an adult needs 360mg caffeine to get diuretic. Oh my god! That is huge. But wait!

We already said that: a cup of coffee has 2 to 7 gm caffeine. So, there is no chance to get diuretic. Yet, some health concerns ask the next questions like:

4. Is decaf coffee harmful to health?

Well, I want to bring Dr. Nandis’s reference here. He concluded this answer in a news channel with some beneficial information.

In that show, the news presenter asked: since the beans go through Methylene chloride chemical, there is a certain health risk. So is it safe?

Brandi replied that: the chemical appearance in the bean is 0.0001%. And it’s completely safe to drink. He also added that, if a person takes the sip within its limits. That’s okay! It’s even better for your health.

5. What are the health benefits of decaf coffee?

The health benefits of decaf coffee are immense. It can reduce type 2 diabetes, heart attack, or even premature death. Even the doctors are also advising to take decaf coffee every day.

They said: a cup of decaf coffee can keep one away from critical disease. Based on the doctor’s point of view, these benefits one can have from the coffee.

  • Decaf coffee reduces the enzymes of the liver.
  • This coffee can also reduce neurodegenerative diseases.
  • Disease like losing memory functions can be improved by decaf coffee.
  • Researchers found that: decaf coffee can reduce rectal cancer risk and heartburn.
  • This coffee can reduce mild depression.
  • Increases the metabolism rate.
  • It burns fat.
  • It improves mood reactions.
  • It even reduces the risk of liver cirrhosis.
  • Decaf can reduce the risk of suicidal thoughts.

6. How many cups of decaf coffee can I safely drink a day?

This is one of the vital questions every coffee enthusiast asks. So, the answer is not more than two cups. Over two cups of decaf coffee can cause these side effects:

Side effects of excessive decaf coffee:

  • Trouble in sleeping
  • Heart arrhythmia
  • Digestive problems
  • Anxiety

This question entices another question: how many cups of regular coffee should one take? Not more than 400mg. If someone takes more than that, these are the side effects they may face.

Side effects of consuming too much regular coffee:

  • Frequent urination
  • Anxiety
  • Headache
  • Increase of heart palpitation
  • Upset stomach
  • Muscle spasm.

Those are the essential information for safe coffee drinking. We are moving to the next phase.

7. Can I drink decaf coffee if I’m Allergic or Intolerant to caffeine?

I found this question on Reddit and then searched for doctors’ advice. The doctor said: it depends on the body condition. According to their research, they did not find any remarkable cases. So, the recommendation is to try a cup of coffee on the weekend. Observe the body reaction. If it’s okay, then don’t worry.

8. Does decaf coffee dehydrate you?

The simple answer is NO. In 1928, a study showed that decaf coffee dehydrates people. But the study proved wrong by many scientists. They said it has the least power to dehydrate. In fact, one should not count it.

Still, some people ask: why does my mouth feel dry during drinking decaf? It’s just a feeling – not dehydration.

9. Does decaf coffee count as water intake?

To answer this question, I need to show the research at the University of Birmingham. The researcher from that university studied people over 18 to 46 years old. They divided them into two sessions.

In the first session, three of the people took black coffee for three days. During those days, the contributors were also advised to drink routine water and eat healthily. They were also advised not to do any physical activity. And that was the first secession.

The next session was a bit different. At that time, the contributors were advised to drink water and less coffee. And these sessions lead to the result after ten days.

The final day: when researchers revealed their result, they found that decaf coffee counts as a similar intake of water.

10. Is decaffeinated tea a diuretic?

The science behind decaf coffee and tea is the same. So, it’s evident that decaffeinated tea has no diuretic. This tea is safe to drink.
