Side-effects of decaf coffee

Tooth decay 

Decaf coffee not only stains your teeth but also deteriorates the enamel of your teeth due to its acidic nature. As a result, your teeth will become sensitive and susceptible to cavities.

Frequent trips to the bathroom

Like regular coffee, decaf coffee stimulates the release of gastrin hormone in the blood which makes your stomach release acid. 

This acid is helpful in digesting food for better absorption. But It also increases gut motility which makes you pee too often. Besides frequent release of stomach acid in large amounts can lead to diarrhea and ulcers over time.

It might be harder to lose weight

Decaf coffee does not have enough caffeine to speed up your metabolism and fat-burning process. Therefore, you might not achieve the same weight loss goals by drinking decaf as compared to regular coffee. 

Besides It you drink your decaf with lots of added sugar, cream and lots of milk, you won’t lose weight.

Your cholesterol may suffer

A 2005 study showed that drinking 3-6 cups of decaf coffee per day resulted in an increase in blood LDL. besides It also increased the levels of specific blood fat which is linked with metabolic syndrome

The effect can be avoided by drinking only a single cup of decaf per day. However, you must be extra careful If you already suffer from high cholesterol.

You may develop an iron deficiency 

Certain polyphenolic compounds, specifically chlorogenic acid, present in both regular and decaf coffee, inhibit the absorption of non-heme iron from the gut. 

This results in brittle nails, changes in taste, hair loss, and ultimately anemia. It is recommended to not consume iron-containing foods and coffee at the same time to avoid malabsorption of iron.
