The age old question about coffee and caffeine. Is caffeine good for you? Or is caffeine bad for you? Well, I wish I had a straightforward answer for you, but I don’t. Instead, I’ve included various studies that show the effects of caffeine on your body.
Good for your liver!
Drinking decaffeinated coffee is just as helpful as drinking regular coffee is for maintaining a healthy liver, a new study finds.

Good for your heart!
Drinking one or more cups of coffee a day may reduce the risk of heart failure, according to new research. But only if it’s caffeinated.

Good overall!
The review also found risk reductions of 5 percent for cardiovascular disease and around 30 percent for both Type 2 diabetes and Parkinson’s disease. A coffee habit was also associated with a lowered rate of death from any cause during the course of a study. Great news for coffee drinkers!

Wait, bad for your heart?
Overall, the team found that heavy coffee consumption—at least six cups per day—is associated with increasing the amount of lipids in the blood, leading to a greater risk of cardiovascular disease.

Side effects
Some side effects linked to excess intake include anxiety, restlessness, tremors, irregular heartbeat, and trouble sleeping.
Too much caffeine may also promote headaches, migraine, and high blood pressure in some individuals.

Ultimately, caffeine can affect each person differently. Research is starting to show how and why certain people metabolize caffeine easier than others.
