This is an often asked question:

Are there any side effects of drinking decaffeinated coffee?

Well, the answer is generally the side effects of drinking decaf coffee are positive, but there can also be less positive side effects as well.

So, what are the positive side effects ff decaffeinated coffee?

Lowered Risks Of Diabetes

Decaffeinated coffee is rich in antioxidants. They can cause a neutralizing effect where they give up their own electrons and this reduces oxidative stress in the body and can help prevents risks of acquiring Type 2 diabetes. 

Besides an abundance of antioxidants, decaf coffee also contains a significant amount of magnesium, which can act as a barrier against diabetes.

Detoxifies The Body

Decaffeinated coffee contains high levels of Vitamin B-3, which boosts the body’s metabolism. This stops the production of fat and helps cleanse the body by eradicating free radicals and foreign materials from it.

Improved Brain Function

Improved brain functions are one of the several benefits that decaf coffee brings to the table. It includes polyphenol compounds that are best known for boosting a person’s cognitive capabilities. This results in enhanced concentration and long-term memory. Additionally, polyphenols are a remarkable tool for battling the early stages of dementia and Alzheimer’s.

Say Goodbye To Caffeine Sensitivity

By drinking decaffeinated coffee, instead of regular caffeinated coffee, all the adverse side effects of regular coffee, namely insomnia, high blood pressure, restlessness, anxiety, or palpitations, can be avoided with decaf coffee.

Better Quality Sleep

Did you know that the half-life of caffeine is five hours? That means that caffeine remains in the bloodstream for a lot longer than we realise. Caffeine can result in hyperactivity which can often be so powerful that it disturbs your sleep patterns, keeping you awake for longer than you would like.

With decaffeinated coffee, particularly if you drink decaffeinated coffee in the afternoon instead of regular coffee, it can also help you catch up on the amount of sleep you had to forego because of regular coffee.

Less Positive Side Effects Of Decaffeinated Coffee

Higher Rates of Rheumatoid Arthritis

This is still a matter of debate and requires more research, but some recent research points to decaffeinated coffee being positively related to the risks of rheumatoid arthritis. The prime reason behind this is the solvents used to decaf the beans for some decaffeination processes. Please note that Decadent Decaf uses the Swiss Water Process of decaffeination, which does not use solvents to decaffeinate the coffee beans.

Can Increase Stomach Acidity

When compared to regular coffee, decaf coffee is less acidic on the pH scale. However, if consumed in large quantities, it can result in a higher concentration of serum gastrin in your stomach. This opens the banks of stomach acid to be released in your body. When this goes beyond a normal levels, it can cause spike in stomach acidity.

Decaffeinated Coffee May Or May Not Have Diuretic Properties

In simple terms, coffee can make you pee more. Coffee with caffeine is seen as being a diuretic, meaning that it promotes the formation of urine by the kidney.But, actually, caffeine is not a strong diuretic - it's a fairly mild diuretic. For many years, it was believed that decaffeinated coffee was also a diuretic, but more recently, scientists now believe that decaffeinated coffee is not a diuretic.

Decaf Coffee May Or May Not Keep You Awake

Some people assert that decaffeinated coffee keeps you awake. It is true that there is some residual caffeine left after the decaffeination process, but this is miniscule. Decaffeinated coffee is between 97% and 99.9% caffeine free depending on the decaffeination process. For example, Swiss Water Decaf coffee is certified 99.9% caffeine free.
