Coffee in the morning has been linked with reduced risk for certain health conditions, including type 2 diabetes and heart disease. Many are left wondering whether regular or decaf coffee would provide more benefits. Both varieties can offer healthful advantages when enjoyed responsibly alongside healthy lifestyle habits.

Though most coffee consumers choose caffeinated varieties, scientific evidence shows that both regular and decaf coffee offer various health advantages. Moderate consumption of all varieties has been associated with increased longevity as well as lower risks of cancers and chronic illnesses.

Coffee contains polyphenols – powerful antioxidants which may reduce risk of heart disease and Type 2 diabetes, among other illnesses. Furthermore, polyphenols may have anti-inflammatory effects as well as improve function in blood vessels and the GI tract.

Coffee was recently associated with lower risk of irregular heart rhythms compared to non-coffee drinkers in the UK Biobank study, an extensive long-term investigation which followed 450,000 adults over 10 years, both caffeinated and decaf varieties found to reduce irregular rhythm risk if consumed without sugar or cream. These results were published by European Journal of Cardiology researchers.

However, the authors of the study acknowledged that their observational study can’t prove coffee to be healthy; there may be other contributing factors beyond coffee that contribute to its positive health effects, including lifestyle factors or genetic traits shared between those who drink coffee and those who don’t.

Other people may be more sensitive to caffeine than others and consuming too much can lead to negative symptoms like jitteriness, sleep disruption, gastrointestinal upset and even racing heart. Luckily, most regulators and health authorities worldwide recommend no more than 400 milligrams a day for adults – equivalent to 2-3 cups (12 ounces each) of coffee per day.

All methods of decaffeination use chemical reactions to extract 97% or more of the naturally occurring caffeine in coffee beans, and typically utilize solvents like methylene chloride as the most popular decaffeination process. All processes have been certified safe by food safety regulators in both North America and Europe and decaf coffee can be integrated into healthy diet plans.
