People often perceive coffee to increase heart attack risk or compromise health; however, moderate coffee intake has proven itself beneficial to overall wellbeing and both regular and decaffeinated varieties offer similar health advantages.

One of the more prominent benefits of drinking coffee regularly is reducing your risk of Type 2 diabetes by improving insulin sensitivity – meaning your body is better at using sugar for energy. One study demonstrated this benefit among participants who consumed four or more cups a day; drinking coffee also helps keep blood sugar levels under control in those already diagnosed.

Coffee may help prevent or treat liver disease by providing essential antioxidants such as choline. Choline protects liver from damage while helping maintain normal cholesterol levels; additionally, coffee contains N-methylpyridinium which may prevent high-density lipoprotein (HDL) cholesterol from accumulating in your system.

Coffee may even help protect against dementia and Alzheimer’s. Scientists believe it may lower the risk of these disorders by blocking receptors for an overexciting chemical called adenosine that causes brain cells to overexcite. Coffee could also reduce amyloid and tau proteins accumulating, potentially contributing to these conditions.

Research demonstrates that coffee may reduce the risk of heart failure and stroke. The protective effect is thought to be linked to its polyphenols (compounds that have physiological benefits) such as those that alleviate oxidative stress and inflammation.

Researchers have also noted that those who drink three or more cups of coffee daily are up to 30% less likely to die of heart disease compared with non-drinkers, likely because regular coffee drinkers typically have lower blood pressure and cholesterol than non-drinkers.

As well as its heart-healthy benefits, coffee can also give an energy and mental alertness boost. A study revealed that those who began their day by sipping a cup of coffee performed better on cognitive tests than those who skipped it – likely due to caffeine’s natural stimulant properties stimulating activity within their brain.

While coffee may provide numerous positive health effects, the results of this study were only observed among those who regularly consumed moderate quantities without overindulging. Therefore, these people could possibly engage in health-promoting behaviors like exercise, sleep and healthy diets more consistently overall. It should also be remembered that typical daily intakes may differ according to demographic and lifestyle factors such as age. Therefore, long-term studies examining actual consumption patterns would provide a more accurate representation of its relationship to health outcomes (JAMA 2018: 319-1942).
