Many are surprised to learn that coffee, in moderation, is considered healthy for the body. Studies have linked moderate coffee consumption with lower risks of heart disease, cancer and diabetes as well as improved mental health and longevity – but it should be noted that overindulging can result in acid reflux, anxiety and lack of sleep as negative side effects.

Coffee contains high amounts of antioxidants that help reduce inflammation and fight disease, while it has also been shown to improve insulin sensitivity, increase metabolism, block receptors responsible for abnormal heart rhythms, and block receptors linked with sudden cardiac death. Furthermore, one recent study discovered that those who drink two to three cups a day have significantly lower risks of heart failure compared with those who don’t consume coffee at all.

Coffee’s anti-inflammatory properties may provide protection from neurodegenerative diseases like Parkinson’s and Alzheimer’s. Furthermore, it helps improve focus and alertness as well as reduce fatigue by blocking receptors for adenosine in the brain. Research has proven this fact.

Coffee beans contain compounds with anti-inflammatory and anti-cancer properties, according to studies. Drinking two or three cups of black coffee without sugar each day has been found to significantly lower risk of Type 2 diabetes than not drinking any at all; those consuming three or four cups daily decreased liver disease risks by up to 80%!

Consuming coffee has also been associated with an increased life expectancy; one study concluded that those who consumed daily cups had up to 30% lower risks of death compared to non-coffee drinkers – this finding being particularly true among those diagnosed with Type 2 diabetes.

Additionally, coffee beans themselves may contain various plant chemicals that help prevent DNA damage and research has revealed that those who drink three or more cups daily of coffee are at reduced risk of Alzheimer’s and Parkinson’s diseases.

However, it’s important to keep in mind that too much coffee may cause adverse side effects, including acid reflux, frequent urination, muscle tremors, insomnia, heart palpitations and anxiety. Furthermore, too much coffee may interfere with certain medications including thyroid medication, antidepressants and antibiotics for UTIs. Studies seem to show that, for most people who enjoy it, consuming one or two plain black coffee beverages every day should not pose any harm and may even provide potential health benefits. However, if you prefer sweetening your coffee with added sugars, take care as too much can counteract any beneficial effects of caffeine. For those sensitive to caffeine, other sources of energy like fruit and vegetables or exercise are advised.
