Moderate coffee consumption – between three to five cups of brewed coffee or six shots of espresso per day – has been associated with lower risks of early death and lower risks of heart disease, type 2 diabetes and Parkinson’s disease. Too much caffeine consumption may cause anxiety, headaches and insomnia and put additional strain on your heart; too much caffeine consumption should not exceed recommended limits; in fact, FDA recommendations state adults shouldn’t exceed 400mg per day (1 shot of espresso contains 63mg).

For maximum health benefits, hot brewed and filtered coffee should be enjoyed without cream or sugar added, though you could experiment with adding healthy spices like cinnamon for sweetness without increasing calories – plus its anti-inflammatory properties!

Coffee also contains polyphenols, phytochemicals with various health benefits. A cup prepared using high-altitude beans with light roasting, fine grinding and served black will contain around 2,500 mg of polyphenols according to Arnot – these polyphenols may protect against diabetes, heart disease liver disease and cancer as well as lower blood pressure through multiple mechanisms including caffeine but also compounds like chlorogenic acid which have been proven to do just that in rats!

Some individuals are more sensitive to caffeine than others and certain medications can affect tolerance levels. If you have preexisting medical conditions such as heart conditions or diabetes, it’s wise to speak to your physician prior to making any dietary changes or making changes on your own.

Although research on coffee’s exact causes remains conflicted, there’s no question that drinking it can have a profoundly beneficial impact on mental health. Studies show that coffee drinkers are at lower risk of depression and suicide, have improved memory performance and reduced risks for neurological diseases like Parkinson’s and Alzheimer’s.

An excess of caffeine is difficult to overdo if you are an otherwise healthy adult who does not combine espresso with other sources, like energy drinks. An individual would need to consume over 150 shots of espresso daily in order to be killed; in reality, however, such an outcome is highly unlikely.

Moderate coffee drinking has been associated with a decreased risk of early mortality in a number of long-term studies, so if you want to reap maximum benefit from drinking coffee, aim for three to five cups daily if possible; otherwise it might be wiser to limit caffeine or medication sensitivity before increasing intake.
