Do you hate the taste of decaffeinated coffee because there’s almost no flavor in it? Well you’re in luck, since there might be a few more reasons to avoid the stuff. People often drink decaf coffee to avoid sleeplessness and other such effects of caffeine. But it isn’t all that good for you.

For starters, decaf coffee isn’t completely “decaf.” In fact, it still contains about 3–4% of caffeine. So, if you think you’re reaping all the health benefits of coffee by drinking 7–8 cups of decaf in a day but avoiding all of the caffeine, you may be wrong. Your decaf coffee can also contain traces of other harmful chemicals left over from the decaffeinating process, which affect your health in the long run.

Side Effects Of Decaf Coffee

1. Increased Risk Of Osteoporosis

Osteoporosis can be one side effect of decaf coffee

Decaf coffee is believed to cause osteoporosis by reducing calcium content in your body. It is known to contain a few compounds that may cause low bone density and lead to weaker bones.1

2. Increased Cholesterol And Heart Problems

Heart problems can be an effect of decaf coffee

Studies have shown that decaffeinated coffee causes elevated plasma cholesterol levels. Researchers found that people who drank more decaffeinated coffee had an 8% rise in apolipoprotein B than people who consumed regular coffee.2 Apolipoprotein B is a type of protein associated with a type of cholesterol linked to heart disease.

3. Heartburn And Acid Reflux

Heartburn is a reason why decaf coffee can be bad for you

If you drink too much of decaf coffee in a day, you might be at risk of developing heartburn or acid reflux. The decaffeinating process is known to increase the acidity levels of the coffee, which may lead to the increased release of gastrin, a hormone that stimulates the production of stomach acid.

4. Increased Risk Of Glaucoma

Glaucoma may be an effect of decaf coffee

Decaf coffee may also put you at the risk of developing eye conditions. It is believed to cause excessive pressure behind your eye, leading to higher risk of glaucoma. However, there isn’t enough research to prove the relation between decaf coffee and glaucoma.

5. Impact On Nervous System

Decaf coffee can be bad for your nervous system

Huge amounts of decaf coffee may have a significant impact on your nervous system. It could have an adverse effect on your heart rate and may increase your blood pressure causing jitters.

A Word Of Caution

If you have to drink decaf coffee, keep the following things in mind:

  • When purchasing decaf coffee, always choose brands with the least amount of caffeine to avoid adverse effects.
  • Drink moderate amounts to avoid any of the side effects mentioned here.
  • Consult your doctor if you aren’t sure about consuming decaffeinated coffee.
