Rumors surrounding coffee’s health benefits have spread like wildfire, with drinking it purported to boost metabolism, improve memory retention and protect the heart. But drinking too much could increase blood pressure, cause anxiety attacks or insomnia and even cancer; nevertheless, most experts agree that having one or two cups a day in moderation may actually be healthy for us all.

Caffeine, which acts like a stimulant and temporarily increases both your blood pressure and heart rate, may temporarily increase them; however, when taken in moderation you become used to it without long-term negative impacts on heart or overall health. Black coffee without add-ins such as sugar, cream or milk and limited intake is likely safe for most individuals.

Studies conducted recently revealed that adults who restricted their daily coffee consumption between 4 a.m. and noon were 16% less likely to die of any cause within 10 years than those who abstained from caffeine entirely. Researchers believe limiting consumption early in the day reduces its negative impact on heart disease risk by keeping blood pressure steady.

Coffee contains antioxidants that protect cells against free radical damage and decrease the risk of chronic disease, as well as magnesium, folic acid and potassium which support heart, muscle, nerve health.

Studies have linked moderate coffee consumption with decreased risks of Parkinson’s and Alzheimer’s diseases. While the exact mechanism remains unknown, scientists speculate that caffeine’s anti-deterioration capabilities may prevent some of the depletion in dopamine levels that comes with ageing and contributes to these disorders.

Coffee may help decrease the risk of cirrhosis and liver scarring in those living with hepatitis C by decreasing harmful liver enzyme levels. Researchers speculate that coffee helps break down fat in your body as well as absorb vitamins A and D more effectively.

Coffee has also been proven to improve insulin sensitivity and glucose control in type 2 diabetes by increasing blood flow to the liver and decreasing resistance, both key factors in controlling blood sugar.

Be cautious when drinking coffee during pregnancy as it can increase uterine contractions and cause nausea. Consult your physician first if you’re planning on discontinuing it as they might recommend waiting until after birth to start drinking again; but if you already enjoy coffee don’t give up just yet – just make sure that it is prepared correctly with no fat or carbs added (a cup of black coffee has two calories; no matter the flavor!), so enjoy as part of a weekly indulgence if desired (just stay away from sugars or cream which add additional calories!).
