Is coffee healthy? The benefits of a cup of joe and when to draw the line

Key Points:

• Sixty-six percent of American adults drink at least one cup of coffee daily, with studies highlighting coffee's potential health benefits such as reducing dementia risk, stress, heart attack risk, and promoting longevity.
• Coffee contains phytochemicals like chlorogenic acid, which has anti-inflammatory properties and may help reduce cardiovascular diseases and Type 2 diabetes by regulating blood sugar and metabolism.
• Caffeine in coffee not only boosts energy and alertness but also protects the neurological system, potentially lowering the risk of Alzheimer's and Parkinson's diseases, and can act as a mild antidepressant by releasing dopamine.
• The FDA considers three to four cups of coffee per day safe for most adults, but individual tolerance varies, and excessive consumption may cause jitters, high blood pressure, and anxiety.
• Coffee's health benefits can be compromised by added sugars, creams, and syrups, which increase calorie and fat intake; moderation and minimal additives are recommended for optimal health effects.
