Like many of us, you likely enjoy enjoying a cup of coffee for breakfast or lunch every day. Coffee has long been associated with health benefits, with studies continuing to back this claim up.

Harvard researchers recently conducted a study and discovered that people who drink three to five measured cups of coffee every day (rather than giant mugs) may be less likely to die from certain illnesses than those who don’t drink coffee regularly, likely because it helps lower blood sugar levels, adds antioxidants that protect cardiovascular health and provides other beneficial compounds.

Only certain individuals should drink coffee, such as those suffering from acid reflux, sleep issues or having a sensitivity to caffeine; but for most people, coffee can be part of a balanced diet and contribute to good health. When making your beverage more healthful make sure not to use added sugars and opt for healthier add-ins such as cinnamon.

1. It Keeps Your Mind Sharp.

Coffee contains caffeine, which acts as a stimulant by blocking an inhibitory neurotransmitter known as adenosine and making you feel more alert and awake – particularly helpful first thing in the morning or at midday slumps.

Coffee has the power to increase both dopamine and serotonin production – both neurotransmitters that help elevate mood and combat depression. Furthermore, it contains polyphenols which may increase how your liver processes glucose while simultaneously decreasing inflammation in your blood vessels.

3. Coffee promotes healthy metabolism. Caffeine in coffee can speed up the rate at which fats are broken down in your body, helping keep weight under control and avoiding fatty liver disease – an infection of your liver that is caused by improperly processing fats you consume – leading to serious liver conditions like cirrhosis.

4. It can help prevent clogged arteries.

Studies suggest that coffee may protect against heart disease thanks to its polyphenols, which help reduce inflammation and blood vessel stiffness. A recent study demonstrated that those who consumed three to five cups per day had significantly lower risks of coronary artery disease and heart attacks compared with those who didn’t drink coffee at all.

5. It Is an Excellent Source of Potassium.

Coffee contains potassium, which has been shown to lower blood pressure and the risk of kidney stones. But don’t rely solely on coffee as your source for potassium; for best results it is best to visit your doctor for regular check-ups on your levels.

There is ample evidence supporting coffee’s health benefits; however, starting to drink it if you have never done so is still not advised, particularly if you suffer from stomach ulcers, sleep or anxiety issues, or are sensitive to caffeine. A better approach would be including it as part of a balanced diet which also includes vegetables and whole grains.
